In dentistry, medical emergencies, even if unforeseen, can still happen. In this case study, a patient presents to a dentist for an implant placement procedure under local anesthesia. During the procedure, the patient suffers a grand mal seizure and is transported to a medical center for care. Later, the patient sues the dentist for negligence, despite lacking medical evidence for the cause of the seizure.

Background Facts

Dr. H is a mid-career, experienced practitioner who has focused on implant dentistry for some years. J, a 50-year-old man with a disclosed history of hypertension, controlled with medication per his history, but no other known medical conditions, presented to Dr. H for her to place a single implant at the site of tooth #30, which had been lost 3 years prior due to a fracture. Radiographs demonstrated that the edentulous area had filled in well with bone that appeared to be of adequate volume and density to accommodate a fixture upon which a crown could eventually be placed.

A 13 mm implant was chosen to be placed into a radiographically-measured 15.5 mm space superior to the inferior alveolar canal. J saw no reason to be sedated for the procedure, as he had always been comfortable during a host of procedures performed under local anesthesia alone. After a thorough informed consent process took place, with written memorialization, Dr. H delivered a long buccal block as well as infiltrations, using 2 carpules of local anesthesia with epinephrine. J tolerated that well, with the area becoming anesthetized within a few minutes, as demonstrated by the lack of any response to a sharp instrument tested at various buccal and lingual locations.

After Dr. H elevated a soft tissue flap following a crestal incision, J became noticeably jittery and started to move around with “odd” opening and closing movements of the jaw, as Dr. H attempted the implant osteotomy. Dr. H briefly stopped work, but as she began again, the movements quickly progressed into what was clearly apparent as a grand mal seizure. Before she was able to stop the bur and remove the handpiece from the mouth, the osteotomy bur pierced through the buccal soft tissue and lower lip, on both sides of the commissure. With Dr. H’s assistance and instruction to her staff, the chairside assistant and Dr. H protected J from causing injury to himself and others, while the receptionist called for EMS.

By the time ambulance personnel arrived, the seizure had ended with J appearing to be in an altered state of awareness. Dr. H placed gauze over the lacerations and maintained hand pressure on them to minimize bleeding. J was then transported to a local medical center, where post-seizure care was provided and where oral and maxillofacial surgery residents repaired the lacerations, and debrided and closed the crestal incision.

J remained an in-patient for a complete neurological work-up, which never reached a conclusion as to the cause of the seizure. After returning home, he shortly resumed his usual activities while remaining under the watchful care of a neurologist. The scar which developed had a keloid appearance which bothered J greatly. Despite 2 scar revision procedures performed by a plastic surgeon, J was constantly self-conscious about his facial appearance, embarrassed to meet new people, both at work and in his social life.

Legal Action

J contacted a “malpractice law firm” whose poster he saw on a subway, wondering whether he might be able to be compensated for what he viewed as a physical deformity. The attorney assigned to handle J’s case soon advised J that he would be filing suit against Dr. H. After Dr. H was served and then assigned defense counsel by her malpractice carrier, the discovery process began. In the usual discovery paperwork, J, through his counsel, claimed that his facial scarring was directly caused by the negligence of Dr. H, namely that she had failed to protect him against the events which took place by having a proper finger rest, that she had failed to timely realize the prodromal stage of the seizure and to act upon that, and in delivering an excess amount of local anesthesia so as to cause the seizure.

The attorneys for Dr. H gathered all of J’s current and prior medical records, with particular focus on J’s post-seizure neurology work-up. They took specific note of the facts that J’s past medical history was as he had described it, and that the neurologist was unable to determine the cause of the seizure.

Armed with this information, as well as the expert affidavits of a dentist, an oral and maxillofacial surgeon, and a neurologist, they sought immediate dismissal of the case by way of a legal approach known as a motion for summary judgment (MSJ). In those MSJ papers, the defense attorneys argued, with the back-up of the experts, that no finger rest could have possibly prevented the seizure from occurring, and without the seizure, there would have been no laceration to develop into a keloid; that seizure prodromal stages are individual to every patient, and with no seizure history, Dr. H could not possibly have foreseen a potential seizure – no less know this patient’s prodromal signs – so as to interpret “odd” movements as being the onset of a seizure; that the amount of local anesthetic was far from excessive; and finally, but perhaps most important, that without a medically-known cause for the seizure, the case cannot legally stand.

In opposition, J’s attorney obtained his own experts, who, in essence, claimed that the adequacy of the finger rest, the lack of timely realization of the seizure prodome (so as to more quickly remove the bur from the mouth), and the amount of local anesthetic given, should be factual matters left for a jury, rather than legal matters to be determined before trial by a judge. Interestingly and tellingly, J’s opposition did not address the unknown cause for the seizure at all. However, it did add in the claim that Dr. H did not take J’s blood pressure prior to the treatment, in direct contravention of recent guidelines distributed by national organized dentistry.

With the court having read all of the motion papers, at the close of oral arguments by both counsel before the court, the case was dismissed in its entirety. The court acknowledged that there could reasonably be disagreement as to whether Dr. H acted appropriately or negligently regarding the adequacy of the finger rest, or her noticing and acting on an impending seizure, or in how much local she delivered, or even in not measuring the patient’s pre-procedure blood pressure. But there could be no disagreement, the court reasoned, that there was no non-speculative way for a jury to conclude that any such negligence was the direct cause of the seizure, because no medical cause for the seizure – whether negligent or otherwise – had ever been determined.

Takeaways

For a plaintiff to be successful in a dental malpractice case, the burden squarely falls on them to prove that (1) there was negligence on the part of the doctor (2) which directly caused (3) the injury complained-of. Failure to prove any one of those three elements is fatal to the claim. Consequently, a defendant need only disrupt any one of those elements to be successful in defense. Here, it was the judge, prior to trial, who determined that the “causation element” could not be proven by the plaintiff, because, without any medical evidence of the cause of the seizure, the claim that Dr. H’s negligence caused it was pure [legally unsound] speculation. In most cases, it is the jury that goes through a similar assessment, although based on the facts rather than legal principles, as to each of the required elements. And without that causation element proven – or as here, even able to be proven – the defendant dentist prevailed, even though she might have arguably been negligent in some aspect of her care. Such is the world of law.

A motion for summary judgment is premised upon a lack of dispute, as to at least one of the required-to-be-proven case elements, between the parties. Therefore, a motion for summary judgment, when submitted by a defendant, need only demonstrate that at least one of the required elements cannot be met by the plaintiff. Here, Dr. H’s attorneys demonstrated to the court that the element of causation could not possibly be met by the plaintiff, warranting immediate, pre-trial dismissal. The court agreed.

The issue of the lack of the measuring of J’s blood pressure by Dr. H raises a few considerations. First of all, while it is true, as plaintiff contends, that guidelines do exist which suggest the taking of a patient’s blood pressure before every invasive procedure, those guidelines do not represent the standard of care, a concept that dental organizations are quick to point out when issuing guidelines. But even if this court had accepted the guidelines as being the equivalent of standard of care, there was no medical evidence that an elevated blood pressure was the cause of this seizure, as previously discussed. The same can be said regarding the propriety or excessiveness of anesthetic dose, because, once again, the inability of the plaintiff to prove the causation element was fatal to his case.

Finally, we briefly discuss the concept of foreseeability, which is no stranger to issues determined by courts. Perhaps it is more accurate to speak about “foreseeability” as “reasonable foreseeability.” There are so many medical conditions and potential medical conditions that afflict patients, that it would be nearly impossible to foresee every medical problem that might come to pass on any given patient. So, while it is readily seen as reasonably foreseeable that even a well-controlled diabetic might suffer from a hypo- or hyper-glycemic event during a procedure, that same level of reasonableness does not exist so as to foresee a grand mal seizure in a patient with no seizure or neurologic history whatsoever. Yes, courts will often hold practitioners liable for foreseeable events, but that is generally interpreted as reasonably foreseeable events. The takeaway here is when you hear hoof beats, think horses, not zebras.

Background facts

E, a 64-year-old man who was markedly obese with type II diabetes and atrial fibrillation, presented for the insertion visit of a PFM crown on his upper right second molar, tooth #2. Getting to that point had been far from easy for both E and Dr. M, owing to limited opening ability and an excess of facial soft tissue. Preparation for the crown and impressioning had each taken a full visit for the very same reasons. Suffice it to say, as Dr. M later did, there was very little room to work in E's mouth. No local anesthesia was given for this visit; as Dr. M placed the crown for what would be the final try-in, his finger incidentally made contact with E's soft palate, causing him to gag and unexpectedly move forcefully, which then caused the crown to slip out of Dr. M's wet gloved hand, and out of sight. Dr. M, an experienced practitioner nearing the end of his career, who liked to work "solo", called an assistant into the room to suction the oropharynx of the supine patient, with the hope of finding the crown tucked into a tissue fold. The crown was not found.

Dr. M explained that he would need to take another impression because the crown had "slipped behind the mouth"; he did just that over the next hour. As E was being dismissed, Dr. M said that the crown will work its way down the intestines, to be voided in the stool: E should inspect his stool over the following few days, to the extent reasonable, but he shouldn't overly worry about it. E left the office, expecting to return in 10 days for the new crown to be inserted.

On the fourth day after this visit, E noticed that his stool was blood-tinged, so he called Dr. M to learn whether that might be related to the dropped crown, but Dr. M did not think so. He did, though, advise E to speak with his primary care physician if things worsened or even remained the same. The stool got redder toward the end of the week, so, that Sunday, he appeared at an urgent care center, where, upon hearing about the dental crown incident, the physician ordered an abdominal series of radiographs, which located the crown, appearing to be stuck in place at a sharp bend in E's colon. Arrangements were made for E to have a colonoscopy the following morning at a local hospital, where E was admitted for the night.

Under deep sedation, a gastroenterologist removed the crown from the colon by using a grabbing instrument. When the crown was examined after removal, the gastroenterologist reasoned that the metal edge of the crown that projected below the porcelain portion — the margin — had likely dug its way just a small amount into a fold in the wall of the colon, preventing it from moving beyond that point to be expelled. Because of E's underlying medical conditions, he was kept in the hospital until the next day, at which time he was discharged without any problems or complications.

Legal action

Although E was willing to let the situation end without any further action, his wife was particularly annoyed about the hospital, anesthesiology, and gastroenterology fees, which were not covered by E's high-deductible medical insurance policy, as well as what she viewed as Dr. M's lack of caring, as demonstrated by his having never followed up with E about what had occurred.

An attorney was brought on board to sue Dr. M for dental malpractice, so that the out-of-pocket costs and a sum for pain and suffering could be recovered. The attorney's first step was to contact Dr. M's malpractice carrier, specifically its regional claims consultant. When all records were obtained and reviewed, the claims consultant explained to Dr. M that a supportive defense expert was unable to be located, even by a local defense attorney, so that a liability defense could not be mounted, other than by way of Dr. M acting as his own liability expert.

Dr. M realized that this was far from an ideal approach, so he agreed to attempts to settle the case, which was accomplished for a relatively modest amount of money.

Takeaways

Under the best of circumstances, maintaining a grip on small objects placed in the mouth, using wet gloves, is fraught with the risk of losing control of the object — here a crown. When treatment is performed in the back of the mouth, that risk is magnified, and when the patient's anatomy makes the working space smaller than usual, the risk further increases. Adding to that, the gravitational considerations of a supine (rather than upright) patient maximize the likelihood of a dropped object being swallowed or aspirated. Each of these "weak points" can generally be mitigated: oropharyngeal packs are placed to try to physically block the backward and downward path, particularly when rubber dam cannot be used; working with a watchful, suctioning chairside assistant provides extra hands, extra eyes and extra protective devices; and seating a patient in as upright a position as possible can mean the difference between a dropped object falling harmlessly into the floor of mouth where it is easily retrievable, and a swallow/aspiration event.

Any and every time that an object is placed into the mouth, or one becomes free-floating in the mouth, and cannot be accounted for, it should be assumed to have been swallowed or aspirated unless proven otherwise, generally by radiographic evidence either way. As a general rule, the sooner the patient is able to be placed into the care of medical colleagues for locating and treating, the less the ramifications will be. That does not necessarily mean that dental procedures must always be stopped in their tracks, but it does mean that, as soon as it is safe for the patient to move on for definitive care, the better off they will usually be. Because physicians are often less than fully aware of dental materials and instruments, it is helpful to them if a photo example, or actual example, is provided to the patient to pass on to their physicians, so that they know exactly what they are looking to locate.

Two considerations which quite often lead patients to seek legal advice are unexpected and unreimbursed costs, and a perception that their dentist did not truly care about them, particularly when things did not go as planned. The former is unpredictable, and it ended up here as one of the main drivers toward legal action, but the latter can almost always be avoided. Prompt and repeated follow-up communication, by the dentist, rather than an office staff member, with patients; and demonstrating a genuine interest in patients, as people and not only "receivers of dentistry"; can go a long way toward heading off involvement of lawyers.

Not all patients and not all similar procedures are the same, whether because of underlying medical issues, patient anatomy, patient size, patient attitudes, or limited mobility. So, a one-size-fits-all approach is rarely, if ever, a helpful treatment mindset to adopt.

Finally, we address the circumstance here, where no liability expert could be found to help to defend Dr. M. While not very common in the defense of dental malpractice claims, it does occasionally pop up. In most, if not all, jurisdictions, dentists are legally permitted to serve as their own experts. But in the eyes of jurors, that is often a difficult sell. In this situation, as well as all other litigation-related issues, dentists are counseled by their defense attorneys, whether the news is easy to hear, or not.

Summary of takeaways:

Take an objective, measured approach to patient communication
Avoid criticizing prior care without full context
Maintain thorough documentation to support care decisions

Sometimes criticizing a patient’s prior dental work can expose dentists to malpractice risk. Understand where the line lies between appropriate patient education and “jousting,” and how communication choices, documentation, and professionalism can influence legal outcomes.

Background facts

Dr. Y was a general, restorative dentist who recently moved into a suburban community—with great public schools—to both live and work. The area's dentists were, generally speaking, busy but not bursting at the seams, so Dr. Y realized that it would not be easy for him to establish his practice with so much competition. His approach would be to sign on to as many dental insurance panels as he could, hoping to use that platform as a foundation upon which to build a patient base. It took a couple of years, but his practice grew.

It was not that Dr. Y would "manufacture" dentistry to perform upon new patients where that need did not exist, but he was what other dentists in the neighborhood described behind the scenes as "hyper-critical" in his evaluations of the dentistry that had been done by prior dentists. R had been a long-term resident of the area, having never had dental insurance until her recent job change. She had completed implant-supported bridgework on both arches some 6-8 months ago, which had cost her a significant amount of money, and she was in the midst of a very slow process of getting used to functioning with the prostheses. With her new employer now providing her with dental insurance—a plan which Dr. Y, but not her prior dentist, Dr. K, accepted—she presented to Dr. Y as a new patient.

At the initial visit, Dr. Y took a full mouth series of radiographs and did a thorough clinical examination. When R mentioned that she "just didn't feel comfortable" with the new dentistry in her mouth, Dr. Y told her that he knew why: the abutments and pontics were overbuilt, with inadequate embrasure spaces; some of the margins were open, although slightly; and the overall dental anatomy did not allow for self-cleansing, making it "a set-up for periodontal disease.” Dr. Y suggested that all of the prosthetics be removed and replaced. Even with R's dental insurance contributing a fair amount to the cost of the proposed treatment, she would still have to pay a large amount of money out of pocket and endure a months-long process. R was very upset, to say the least, focusing that displeasure on Dr. K; she had always known that a replacement of Dr. K's work would likely be required down the road, but she did not expect that so soon after it was inserted.

Dr. Y removed the existing bridges, replaced the implant abutments, re-prepared the natural teeth, impressioned and temporized the mouth, and ultimately inserted new upper and lower cases. R was no happier with the new work, but Dr. Y told her that there was only so much he could do with the underlying foundation that Dr. K had "inadequately established,” so R would simply have to adjust. She never fully did.

Legal action

With R continually complaining to family members and friends about how unhappy she was, not only dentally, but also because of the money she had paid both Dr. K and Dr. Y, while exhausting her annual dental insurance benefits so early in the calendar year, she was encouraged to seek out an attorney who might have some solutions for her. R's newly retained attorney obtained the dental records of Drs. K and Y, as well as a narrative from Dr. Y, in which he was quite critical of Dr. K's work product, which was directly responsible for the need to exchange it and for the inability to create a more ideal replacement (due to the underlying damage it/he had caused).

When Dr. K reported the contact from R's attorney to his malpractice carrier, he was provided with defense counsel, who was able to obtain the records and report from Dr. Y. Dr. K was in literal disbelief at what he saw in writing, but he knew that it would be a difficult task, from a dental standpoint, to demonstrate the quality of his work, with it having been removed and replaced. At the same time, he felt bad for R, his patient of many years, whom he believed had been sold an inaccurate story, for the sake of Dr. Y's financial gain.

With Dr. K's counsel functioning as an intermediary at Dr. K's request, an offer was made to refund to R all that she had paid to Dr. K, in order to stave off the prospect of a lawsuit. R, through her attorney, accepted that offer, with the money changing hands once R executed a Release of Liability document.

Takeaways

As healthcare professionals, dentists are ethically obligated to advise patients regarding the conditions of their mouths, including the status of existing dental work. But without having ever stood in the shoes of a prior-treating dentist, and not knowing what challenges and limitations might have been placed upon them, or how the patient took care of themselves dentally after that treatment, blanket criticisms that do not take any of these potential factors into account are known in the malpractice world as "jousting" —not the medieval game involving horses and lances, but with similar effect. Part of professionalism is being able to candidly communicate with patients without denouncing the work of others, absent full knowledge of all contributing factors. Here, while Dr. Y acted appropriately by advising R of his findings—presuming that he did, in fact, find deficiencies and problems—he stepped into the jousting arena by doing so in a manner that made certain presumptions of blameworthy wrongdoing. It is a fine line to walk, and one to be figured out by all practitioners. Jousting, as compared with notifying, is a significant driver of dental malpractice claims; why that practice is as common as it is, perhaps more so than in other professions, is a speculative exercise for consideration elsewhere.

Dr. K's decision to try to resolve R's complaints by offering, and ultimately providing, a refund was a personal one, considering all of the issues involved with defending a protracted dental malpractice case, as compared with taking all of that off of his plate quickly. Refunds are far from uncommon in dental practice; when provided, dentists are wise to protect themselves legally by obtaining a Release of Liability (ROL), signed by the patient, in exchange for the returned money. In essence, a ROL in this context states that the patient is willing to accept a monetary benefit, while relinquishing the right to later sue the dentist regarding the course of conduct that led to that refund. As with all legal documents, ROLs are best prepared and overseen by attorneys, who can assure that the process is carried out in the most appropriate manner, so as to afford the best level of protection. We do note, however, that no ROL will prevent a patient from subsequently making a complaint to a state Dental Board, as the right to report to government entities cannot be given up through a civil process, such as a refund or a settlement. For better or worse, that is the way it is.

Dr. Y's preparation of a narrative for an attorney is an everyday occurrence. In many jurisdictions, attorneys for patient-plaintiffs are required to obtain some sort of statement, whether written or otherwise, from a dentist, in which that dentist states, in terms of varying specificity, that the treating dentist who is being considered as a potential defendant violated the standard of care, thereby leading to damage to the patient. Such statements are opinions, and opinions vary much of the time, but that is how the system works. To add to the difficulties in defending cases like this, particularly involving restorative dentistry, the work that is later claimed to have been deficient will, by definition, have been removed and replaced, so there can be no after-the-fact reviewing of the criticized work by the defendant and/or his/her defense expert. That serves as yet another reason that documentation (including post-placement radiographs, when appropriate) is so important, as it might well be the only "living" evidence of steps taken and rationales for doing so. Time-consuming as it is, documentation is not something to shortcut: that includes dentists writing their own chart entries, rather than having an assistant or other staff member do it for them.

Summary of takeaways:

Criticizing prior work without full context can increase malpractice risk.
Keep patient communication objective and avoid assigning blame.
Thorough documentation is critical for defending care decisions.

Background facts

Dr. S was a well-experienced dental practitioner who focused on the care of children, although not a pediatric dentist: she found the work challenging, yet rewarding, especially when those children later brought their own children to be treated. R, age 16, was one such patient, whose father, as a teenager, treated with Dr. S when she was new to practice. Severe, right maxillary pain, with persistent headaches led R to come to the office, outside of the routine of his usual 6-month recall visits. By way of evaluating appropriate periapical films of the upper right molars and premolars, as well as a clinical examination with multiple dental testing modalities that demonstrated equivocal findings, Dr. S concluded that the problem was most likely originating with tooth #3 and/or tooth #4, as both had deep MOD restorations placed approximately 3 years prior.

The more likely offending tooth, in the opinion of Dr. S, was the first molar, so, with the approval of R's father, root canal therapy was completed on that tooth, without any apparent complication, and with the finding of a vital pulp. Nearly a month later, R's symptoms continued as before the endodontic treatment, so, again with the father's agreement, Dr. S completed RCT on tooth #4, also without complication and also with a vital pulp. Despite both teeth being subsequently restored, R's initial presenting complaints remained, and were even subjectively worse, now approaching 6 months later; additionally, R began to have right-sided sinus congestion.

R's parents arranged for him to see an ENT, who, after performing a limited clinical assessment, sent R for a CT of the sinuses. The study clearly showed a well-circumscribed, lima-bean-sized mass in the right maxillary sinus, located seemingly entirely deep to the Schneiderian Membrane and just above the maxillary posterior teeth. Because of its localized appearance, the ENT expressed to R and his parents that the lesion was likely benign, so a plan was developed to perform an exploratory surgical procedure, through a Caldwell-Luc approach, to excise the mass and examine it microscopically. Surgery at a local hospital went forward under general anesthesia, with the lesion removed and the sinus debrided. The biopsy report determination was that the lesion was a polyp which was, as anticipated, benign and in need of no further treatment.

Within 2 weeks, R was, for the first time in the better part of a year, free of pain and headaches. The ENT concluded and stated to his patient and his parents that all of the symptoms were all along not due to any dental problem, but instead the sinus polyp. It was not until over a year after the RCTs were completed that R's father questioned Dr. S as to why she failed to diagnose "something" abnormal in the sinus, why she failed to consider any source for R's complaints other than teeth, and why she performed root canal therapy on 2 teeth without any objective basis for doing so. Although she apologized and expressed empathy for all that R had gone through, she was not able to provide any answers to the direct questions posed to her.

Legal action

R's father read online that teeth which have had root canal therapy are more likely to fracture, and therefore be prematurely lost, so he began to consider costs that would likely and unnecessarily need to be borne by R in the future, as well as the emotional distress he would endure if he had to go through multiple dental extractions and their replacements. He sought out and retained an attorney to act on his son's behalf by suing Dr. S for dental malpractice.

When Dr. S was served with papers that had commenced a lawsuit against her, she was immediately faced with a practical reality that she was aware of but had not realistically considered would arise: she had recently changed malpractice carriers but had not purchased extended reporting coverage – a "tail" – for the first carrier's claims-made policy; because the treatment of R which was at issue took place during the period of the earlier policy, she had no insurance coverage, either for defense or indemnification (payment). After looking at the legal costs she would have to personally bear as a result, she opted to represent herself – acting pro se – counting on some "unofficial" help from a close friend who was an attorney, although not one who had ever practiced in the professional malpractice arena.

Dr. S learned that the state in which she practiced dentistry had a 1-year statute of limitations period for dental malpractice cases, meaning, as she interpreted it, that no such suit against her could validly go forward if it had been started more than 1 year after the date(s) of the claimed negligent treatment, as this suit had. She asked her attorney friend what she could do to stop the suit in its tracks because it was not timely begun: her friend said that the mechanism for doing that was to make a motion to the court for dismissal, on that specific basis. With her friend unwilling to assist her beyond that sole piece of advice, Dr. S thoroughly researched how to place that before the court, realizing that this was her only true hope to be successful in defending the case, acknowledging that she had fallen short in diagnosing the actual problem R had, and instituting incorrect and unneeded treatment. Dr. S's motion was quickly and decisively opposed by the lawyer for the plaintiffs, R and his father.

The opposition made it clear that Dr. S had relied on only a portion of the law which guided the statute of limitations, ignoring the critical part here, namely that R, as a minor, was entitled to an extension of that time period, such that he was permitted to file his case until 1 year after he reached the age of majority; given that R was well short of age 19, the judge denied Dr. S's motion and allowed the case to move forward. This left Dr. S with 3 basic options: (1) hire a lawyer to represent/defend her (which she was not willing to do); (2) continue to represent herself through discovery and potentially trial; or (3) try to reach a settlement to end the case. She weighed the costs, likelihood of success, and an unknown amount of money to be paid out if R later prevailed, if she proceeded with her defense, versus taking the bitter pill right then and there, and resolving the case for a sum of money that would be acceptable to all involved. She opted for the latter, and was able to work with R's attorney to reach an amicable settlement amount, which covered out-of-pocket expenses and compensation for R's pain and suffering after Dr. S completed her treatment.

Takeaways

The statute of limitations is the amount of time a plaintiff has to initiate suit. States differ as to whether that time clock begins at the time of the negligent action, or when the effects of that negligent action are discovered, or small variations on those themes. But regardless of those differences, the amount of time allowed by each state is strictly fixed for the vast majority of cases. The most frequent exception in nearly all, if not all, of the states is that minors are entitled to an extended amount of time within which to begin a suit in dental malpractice, with the exact length of that time extension also specific to each state. As a tandem concept, many states also require that dentists maintain records for minors longer than for adult patients; practitioners need to be aware of these details, lest they destroy records prematurely, thereby setting up significant legal issues if they cannot produce records during litigation or in response to a Board complaint, at a time when they should still have been maintained.

This case speaks also to both the type and quality of radiographs. Here, while Dr. S was able to radiographically visualize the entirety of the teeth she treated, which is a generally agreed-upon requirement in the dental community, she was unable to visualize the neighboring maxillary sinus. While dentists might legitimately debate whether Dr. S should have taken or ordered a radiographic study (such as a panoramic or CBCT) that also captured the sinus, there is no such dispute that, regardless of how and with what diagnostics she went about it, it was her obligation to assure that she was treating the situation for which the patient was seeking treatment. According to the ENT – by way of what might reasonably be viewed as a joust – Dr. S did not do so. But whether a joust or simply a statement of symptom causation, it was that conclusion by the ENT which most prominently led Dr. S to settle the matter rather than fight it.

Finally, we address the factors which left Dr. S without professional liability coverage: her claims-made policy and her not having purchased a tail upon leaving that policy behind in favor of another. While an occurrence policy will forever protect a dentist – whenever a lawsuit might be filed – if a negligent action took place while that policy was in effect, a claims-made policy will only provide coverage if it is in effect at the time a claim of negligence/malpractice is made, unless a tail was purchased to extend the coverage umbrella of a claims-made policy which is no longer in effect. Some exceptions to the need for a tail – such as death, disability, or retirement – might exist, based upon the stated policy terms, but for the most part, it is the norm that a dentist will be left as Dr. S was if they close a claims-made policy without purchasing tail coverage.

Summary of takeaways:

Broaden the diagnosis: Persistent or unclear symptoms should prompt consideration of non-dental causes and appropriate referral.
Avoid unnecessary treatment: Repeating irreversible procedures without clear evidence increases patient harm and liability risk.
Know your legal exposure: Treating minors can extend the statute of limitations, and gaps in malpractice coverage can leave you personally liable.
