Dental and Oral Surgery Injuries: What Louisiana Patients Should Know

She went in for a routine lower wisdom tooth extraction on a Friday morning and woke up from the sedation with numbness across her lower lip and the right side of her chin. The oral surgeon told her it was normal swelling. Two weeks later, the numbness was the same. Six weeks later, she was referred to a neurologist. The damage to her inferior alveolar nerve, they told her, was likely permanent. She'd never been told that was a meaningful risk of the procedure.

Dental procedures cause serious, permanent injuries more often than most patients expect, and the legal path for getting compensated in Louisiana is more specific than many families realize. This article covers the foundation: how CC Art. 2315 and the Louisiana Medical Malpractice Act (La. R.S. 40:1231.1 et seq.) apply to claims against dentists and oral surgeons, what the standard of care requires under La. R.S. 9:2794, what types of injuries lead to successful claims, and how the 2026 modified comparative fault rule under CC Art. 2323 plays out in dental cases.

How Louisiana Law Treats Dental Malpractice Claims

Dentists in Louisiana are licensed healthcare providers. A claim that a dentist's treatment fell below the accepted standard of care is a medical malpractice claim, governed first by CC Art. 2315 and then filtered through the Louisiana Medical Malpractice Act for providers who qualify.

Most practicing Louisiana dentists maintain LMMA-qualified status, which means they've enrolled with the Patient's Compensation Fund. For those providers, a patient with a malpractice claim must first submit it to a medical review panel before filing suit in court. The panel consists of three licensed healthcare providers in the same or a closely related specialty, plus an attorney chairperson. The panel reviews the medical and dental records and issues a written opinion on whether the standard of care was met. The opinion is admissible at trial but doesn't bind the jury.

The LMMA also caps non-economic damages against qualified providers at $500,000 per occurrence. The Patient's Compensation Fund covers amounts above the individual provider's $100,000 share. Economic damages, the cost of corrective treatment, lost wages, future care costs, are not subject to the LMMA cap and can exceed it substantially in cases involving serious permanent injury.

For dentists who are not LMMA-qualified, the claim can be filed directly in court without a panel, and no cap applies to any category of damages. The tradeoff is that unqualified providers are also not protected by the PCF, meaning the patient recovers directly from the provider or their insurer rather than the fund.

What the Standard of Care Requires

Louisiana Revised Statutes § 9:2794 sets out the standard of care for licensed healthcare providers, including dentists. The statute requires the level of care, skill, and treatment ordinarily exercised under the same or similar circumstances by a member of the provider's profession in good standing in the same community or a similar one.

For general dentists, the standard is measured against other reasonably competent general dentists. For specialists, it's measured against other practitioners in that specialty. An oral surgeon performing a wisdom tooth extraction is held to the standard of a reasonably competent oral surgeon, not just a general dentist who also extracts wisdom teeth. That distinction matters, because specialists take on cases with greater complexity and are expected to bring greater skill to managing the risks those cases carry.

The standard of care is established through expert testimony. An attorney doesn't just assert that the dentist did something wrong; they engage a qualified dental expert who reviews the records, the radiographs, the treatment notes, and the informed consent documentation, and then renders an opinion on what a reasonably competent practitioner would have done differently. Without that expert, there is no malpractice case, regardless of how severe the outcome.

The standard also governs what a dentist is required to tell the patient before a procedure. Informed consent is not just a signature on a form. A dentist is required to disclose material risks, the risks a reasonable patient would want to know about before agreeing to a procedure. Failure to obtain meaningful informed consent, when the undisclosed risk materializes and causes harm, is itself a basis for a malpractice claim.

Types of Injuries That Lead to Dental Malpractice Claims

Nerve damage is the most frequently litigated dental malpractice injury in Louisiana. The inferior alveolar nerve, which runs through the lower jaw, can be damaged during lower wisdom tooth extraction, implant placement, or endodontic treatment, resulting in permanent numbness or altered sensation in the lip, chin, and gum. The lingual nerve, which supplies the tongue, can be damaged during lower third molar extraction, causing permanent loss of taste or sensation on one side of the tongue. Both injuries are known complications of certain procedures, and both can be malpractice when the dentist failed to identify the nerve's proximity on preoperative imaging, chose a technique that created unnecessary risk, or failed to warn the patient of a meaningful risk before proceeding.

Wrong tooth extraction is straightforward to prove but still happens. A tooth extracted on the wrong side, or the wrong tooth in a quadrant where two adjacent teeth had similar radiographic appearance, results in the unnecessary loss of a healthy tooth. The affected patient typically needs an implant or bridge to replace what shouldn't have been removed, and the cost of that corrective treatment is recoverable.

Endodontic perforations occur when a file or instrument used in root canal treatment perforates the root wall, creating an opening between the root canal and the surrounding bone or periodontal tissue. An undetected perforation leads to infection, bone loss, and often tooth loss. The question for malpractice purposes is whether adequate radiographic monitoring was used and whether the perforation was recognized and managed promptly when it occurred.

Delayed or missed diagnosis of oral cancer is a particularly serious category. Dentists have a professional obligation to visually screen for oral lesions and to biopsy or refer suspicious findings. A dentist who observes a lesion, documents it as unremarkable, and does not follow up or refer over the course of multiple appointments while the cancer advances has potentially created a case for delayed diagnosis malpractice. The damages in these cases, which may include advanced-stage cancer treatment costs, disfigurement, and lost life expectancy, can be severe.

How Louisiana's 51% Comparative Fault Rule Applies

Under CC Art. 2323, a jury assigns fault percentages to all parties including the patient. A plaintiff found more than 50% at fault recovers nothing; below that, recovery is reduced by the plaintiff's share.

In dental cases, comparative fault defenses typically focus on the patient's own conduct: delayed follow-up after a complication was first noted, failure to disclose medical history that affected treatment risk, or failure to attend required post-operative appointments. These arguments are raised even in cases with clear provider fault, because reducing the plaintiff's recovery by even 20% moves substantial money on cases with high damages.

Here's how the arithmetic looks in practice. A patient undergoes implant placement at a Lake Charles dental practice and develops permanent numbness from inferior alveolar nerve damage. The jury values damages at $280,000. The dentist is found 80% at fault for failing to take a cone beam CT scan before placement in a region where the panoramic X-ray showed the nerve positioned unusually close to the planned implant site. The patient is found 20% at fault for not disclosing a prior jaw fracture on the medical history form, which had altered the nerve's position. Recovery: $280,000 x 0.80 = $224,000. The undisclosed history reduced recovery by $56,000, but the case remained worth bringing.

Had the patient's undisclosed history been the dominant cause, shifting their fault share above 50%, the recovery disappears. Full medical history disclosure is not just good clinical practice. In litigation, it's the difference between recovery and nothing.

Frequently Asked Questions

Does the Louisiana Medical Malpractice Act apply to dentists?

Yes, for dentists enrolled as qualified healthcare providers with the Patient's Compensation Fund. For those providers, a mandatory medical review panel precedes any lawsuit, and non-economic damages are capped at $500,000 per occurrence. Most practicing Louisiana dentists carry LMMA-qualified status. Dentists who are not LMMA-qualified can be sued directly without a panel and without the cap, but this is the minority of cases. Confirming a dentist's LMMA status at the start of a case is one of the first things an attorney does.

What is the standard of care for a Louisiana dentist?

The level of care, skill, and treatment that a reasonably competent dentist in the same specialty would exercise under the same or similar circumstances, as defined by La. R.S. 9:2794. For specialists, the standard is measured against other practitioners in that specialty. The standard is established through expert testimony from a qualified dentist who reviews the records and renders an opinion on what competent care required. A bad result standing alone does not prove the standard was breached.

What types of dental injuries are most common in malpractice cases?

Permanent nerve damage (inferior alveolar or lingual nerve) from wisdom tooth extraction or implant placement, wrong tooth extraction, endodontic perforations during root canal treatment, failed or improperly placed implants, delayed or missed diagnosis of oral cancer, and anesthesia or sedation complications. Each category turns on whether the provider deviated from what a reasonably competent dentist would have done, not just on whether the outcome was bad.

How long do I have to file a dental malpractice claim in Louisiana?

One year from the date of discovery under Louisiana's discovery rule. Filing a complaint with the Patient's Compensation Fund tolls the prescriptive period for LMMA claims while the panel is pending. Without that PCF filing, the one-year period continues to run regardless of other steps the family may be taking. Don't assume that requesting records, seeing another dentist, or sending a complaint letter to the dental board extends the legal deadline. It doesn't.

Do I need a dental expert to bring a malpractice claim?

Yes, as a practical matter. The medical review panel process requires expert submissions, and trial requires qualified expert testimony establishing that the standard of care was breached. The clinical decisions in dental malpractice cases, radiographic interpretation, technique selection, nerve proximity assessment, biopsy judgment, are outside a lay jury's expertise. An attorney experienced in dental malpractice cases has established relationships with qualified dental experts in the relevant specialties and begins that process early in the representation.
