Dental Malpractice Lawyer NYC: Suing for Nerve Damage & Implant Errors

Common Types of Dental Malpractice

Dental malpractice cases in New York typically fall into several categories:

• Nerve damage: Injury to the inferior alveolar nerve (IAN) or lingual nerve during wisdom tooth extraction, dental implant placement, root canal, or local anesthetic injection — causing permanent numbness, tingling, pain, or loss of taste. [Link to: /surgical-errors/nerve-damage]
• Dental implant errors: Improper placement of dental implants — including drilling too deep, placing implants into the maxillary sinus or mandibular nerve canal, or using incorrect technique — causing nerve damage, infection, implant failure, or bone loss.
• Anesthesia errors: Improper administration of local or general anesthesia during dental procedures — causing nerve damage, brain injury from hypoxia, or death. [Link to: /medical-malpractice/anesthesia-error]
• Extraction errors: Wrong tooth extraction, fractured jaw during extraction, or failure to properly manage complications like dry socket or infection.
• Root canal errors: Breaking instruments inside the root canal, perforating the tooth root, failing to remove all infected tissue, or using improper filling materials — causing chronic infection and eventual tooth loss.
• Failure to diagnose oral cancer: Failing to screen for or identify signs of oral cancer during routine dental examinations — allowing cancer to progress to advanced stages. [Link to: /medical-malpractice/cancer-misdiagnosis] [Link to: /misdiagnosis/oral-cancer-misdiagnosis]
• Failure to diagnose periodontal disease: Failing to diagnose and treat gum disease — leading to tooth loss, bone loss, and systemic infections.
• Failure to diagnose odontogenic infections: Dental abscesses and infections that spread to deep neck spaces, the mediastinum, or the brain — causing life-threatening sepsis, Ludwig's angina, or brain abscess. [Link to: /medical-malpractice/failure-to-diagnose-infection] [Link to: /delayed-diagnosis-lawyer/brain-abscess]
• Orthodontic errors: Improper orthodontic treatment causing root resorption, TMJ (temporomandibular joint) damage, gum recession, or bite problems.
• Inadequate informed consent: Failing to adequately explain the risks of a dental procedure — particularly the risk of nerve damage from wisdom tooth extraction or implant placement. [Link to: /surgical-errors/informed-consent]
• Improper sterilization and infection control: Failing to follow proper sterilization protocols — leading to cross-contamination and transmission of hepatitis, HIV, or bacterial infections. [Link to: /hospital-negligence/hospital-infections]

Nerve Damage from Dental Procedures

Dental nerve damage is the most common and devastating injury in dental malpractice cases. Two nerves are most frequently injured:

The Inferior Alveolar Nerve (IAN): This nerve runs through the lower jaw (mandible) inside the mandibular canal — carrying sensation from the lower teeth, chin, and lower lip. It is vulnerable during wisdom tooth extraction (third molar extraction), dental implant placement in the lower jaw, and root canal treatment of lower molars. Injury causes numbness, tingling, and pain in the chin, lower lip, and teeth on the affected side.

The Lingual Nerve: This nerve runs near the base of the tongue — carrying sensation and taste from the anterior two-thirds of the tongue. It is vulnerable during wisdom tooth extraction (particularly the lingual approach), local anesthetic injection (particularly inferior alveolar nerve blocks), and tongue surgery. Injury causes numbness, tingling, pain, and loss of taste on the affected side of the tongue.

How dental nerve damage happens:

• Surgical trauma: The dentist or oral surgeon cuts, crushes, stretches, or burns the nerve during extraction or implant placement.
• Implant placement: A dental implant is drilled too deep or placed in the wrong position — compressing or penetrating the mandibular canal and the IAN.
• Anesthetic injection: A local anesthetic injection (particularly inferior alveolar nerve block) directly hits the nerve with the needle — or causes neurotoxic injury from the anesthetic itself.
• Root canal treatment: Endodontic instruments (files) or filling materials (gutta-percha, sealant) are pushed beyond the root apex — entering the mandibular canal and injuring the IAN.
• Excessive traction: The surgeon uses excessive force during wisdom tooth extraction — stretching the nerve and causing traction injury.
• Thermal injury: Surgical drills generate heat — and excessive drilling without irrigation can cause thermal nerve injury.

Dental Implant Errors and Failures

Dental implant placement has become one of the most common dental surgical procedures in New York — and also one of the most common sources of dental malpractice claims. Implants require drilling into the jawbone to place a titanium screw that serves as an artificial tooth root. Errors during this process can cause serious, permanent harm.

Common dental implant errors:

• Implant placed into the mandibular canal: The dentist drills too deep or at the wrong angle — placing the implant directly into the inferior alveolar nerve canal, causing severe and often permanent nerve damage.
• Implant placed into the maxillary sinus: In the upper jaw, the dentist drills through the sinus floor — causing chronic sinus infections and implant failure.
• Improper treatment planning: Failing to properly evaluate the patient's bone structure with 3D CBCT imaging (cone beam computed tomography) before placing the implant — leading to improper placement.
• Inadequate bone assessment: Placing an implant in an area with insufficient bone — causing implant failure, bone loss, and damage to adjacent teeth.
• Failure to use a surgical guide: Placing implants freehand — without a surgical guide — increasing the risk of malposition.
• Improper implant selection: Using the wrong size or type of implant for the patient's anatomy.
• Inadequate sterilization: Causing post-operative infection at the implant site.
• Failure to obtain informed consent: Not adequately explaining the risk of nerve damage — particularly the risk of permanent IAN injury when placing implants in the lower jaw.

Anesthesia Errors in Dental Procedures

Dental anesthesia — both local and general — carries significant risks. Anesthesia errors in dental settings can cause nerve damage, brain injury, or death.

Local anesthesia errors:

• Direct nerve injury: The needle directly hits the nerve during injection — causing laceration or compression injury.
• Neurotoxic injury: Local anesthetics (particularly articaine and prilocaine) can be neurotoxic — and injection into or near the nerve can cause chemical nerve injury.
• Intravascular injection: Injecting anesthetic into a blood vessel — causing systemic toxicity, seizures, or cardiac arrest.
• Failure to aspirate: Not checking for blood return before injecting — increasing the risk of intravascular injection.

Failure to Diagnose Oral Cancer and Periodontal Disease

Dentists play a critical role in screening for oral cancer and periodontal disease. Failure to diagnose these conditions can have devastating consequences.

Oral cancer screening: The standard of care requires dentists to perform an oral cancer screening during routine dental examinations — visually inspecting and palpating the lips, tongue, floor of the mouth, buccal mucosa, palate, and oropharynx for suspicious lesions, ulcers, or masses. Risk factors include tobacco use, alcohol use, and HPV infection.

When a suspicious lesion is identified, the standard of care requires referral for biopsy. Failure to refer — or failure to follow up on abnormal findings — allows cancer to progress, potentially from a treatable early stage to an advanced, disfiguring, or fatal stage. [Link to: /medical-malpractice/cancer-misdiagnosis] [Link to: /misdiagnosis/differential-diagnosis]

Periodontal disease: The standard of care requires dentists to screen for periodontal (gum) disease — using probing depths, attachment levels, and radiographic assessment. Untreated periodontal disease leads to tooth loss, bone loss, and has been linked to systemic conditions including cardiovascular disease, diabetes, and adverse pregnancy outcomes.

Failure to diagnose and treat periodontal disease can cause irreversible tooth loss — and may constitute dental malpractice when the disease was evident on examination but not addressed.

The Standard of Care in Dentistry

The standard of care in dentistry is established by the American Dental Association (ADA), specialty boards (including the American Association of Oral and Maxillofacial Surgeons, American Academy of Periodontology, American Association of Endodontists, and American Association of Orthodontists), and peer-reviewed dental literature.

Key elements of the standard of care include:

1. Proper diagnosis and treatment planning: Conducting a thorough examination — including appropriate radiographs (X-rays) and, when indicated, 3D CBCT imaging — before planning treatment.

2. Appropriate imaging: Using the right imaging modality for the procedure — including periapical radiographs, panoramic radiographs, and CBCT for implant planning, complex extractions, and root canal treatment.

3. Proper technique: Following accepted dental techniques for each procedure — including proper surgical technique for extractions and implants, proper endodontic technique for root canals, and proper restorative technique for crowns and fillings.

4. Referral to specialists: Recognizing when a case is beyond the dentist's training or experience — and referring to an appropriate specialist (oral surgeon, endodontist, periodontist).

5. Informed consent: Adequately explaining the risks, benefits, and alternatives of each procedure — particularly the risk of nerve damage from wisdom tooth extraction and implant placement. [Link to: /surgical-errors/informed-consent]

6. Infection control: Following CDC and OSHA sterilization and infection control protocols.

7. Follow-up: Monitoring patients after procedures for complications — and addressing complications promptly when they arise.

When a Bad Outcome Becomes Dental Malpractice

Not every bad dental outcome is malpractice. Dental procedures carry known risks — including a small risk of temporary nerve injury from wisdom tooth extraction that resolves on its own. However, certain outcomes strongly suggest negligence:

- Permanent nerve damage that does not resolve within 6 months — particularly when the nerve was directly injured by surgical instruments or implants. - Wrong tooth extraction — extracting the wrong tooth is almost always negligence. - Dental implant placed into the nerve canal or sinus — particularly when proper CBCT imaging was not used for planning. - Broken instruments left inside a root canal — particularly when the patient was not informed. - Severe infections that spread to deep neck spaces or the brain — particularly when the dentist failed to recognize or treat the infection. - Failure to diagnose oral cancer that was visible on examination — allowing it to progress. - Anesthesia complications — including brain injury from hypoxia during sedation.

To prove malpractice, expert testimony from a qualified dentist — typically in the same specialty as the defendant — is required under CPLR § 3012-a (certificate of merit).

Proving Causation in Dental Nerve Injury Cases

Proving that dental negligence caused nerve damage requires establishing:

1. The standard of care was breached: Expert testimony that the dentist used improper technique — improper implant placement, excessive force during extraction, or failure to use imaging.

2. The breach caused the nerve injury: Expert testimony linking the specific breach to the nerve injury — based on the timeline, imaging studies, and clinical examination.

3. The nerve injury is permanent: Expert testimony from a neurologist or nerve injury specialist confirming that the nerve injury is permanent — based on clinical examination, sensory testing, and nerve conduction studies.

The defense may argue that nerve injury is a known risk of dental procedures, that the patient had pre-existing nerve proximity, or that the injury would have occurred regardless. Expert testimony is required to counter these arguments — particularly distinguishing a known risk from negligent technique. [Link to: /surgical-errors/error-vs-known-risk]

New York Statute of Limitations for Dental Malpractice

Dental malpractice in New York is governed by the same statute of limitations as medical malpractice — 2.5 years from the date of the negligent act (CPLR § 214-a). The continuous treatment doctrine may extend the deadline if you continued receiving treatment from the same dentist for the same condition. For wrongful death, the deadline is 2 years from the date of death (EPTL § 5-4.1).

Important: Dental nerve damage may not be discovered immediately — and the statute of limitations clock starts on the date of the procedure, not the date the injury was discovered (unless Lavern's Law applies to cancer cases). Contact a dental malpractice lawyer as early as possible. [Link to: /medication-errors/statute-of-limitations] [Link to: /wrongful-death/statute-of-limitations]
