Dental Procedure Caused Nerve Damage in California — What to Document

You went in for what was described as a routine procedure — a wisdom tooth extraction, a root canal, an implant placement, a deep restoration. You expected soreness for a few days and then a return to normal. Instead, something else happened. The numbness in your lip or chin or tongue did not lift. The tingling, the strange burning, the altered taste, the patch of skin or mucosa that feels like it belongs to someone else — none of it has resolved on the timeline you were told to expect. Maybe a week has passed. Maybe months. The dentist's office may have told you it would "wake up." A friend may have told you to see a neurologist. You may not know whether what you are experiencing is a known and accepted risk of the procedure or whether something went wrong.

This page is for the moment you are in right now: still inside the medical question, not yet certain about anything legal, and trying to figure out what to do next without making the situation worse.

xCounsel is not a law firm and does not itself represent you in personal-injury, medical-malpractice, dental-malpractice, plastic-surgery harm, or family-law matters, though for these matters it helps you organize your records and routes your matter to a California attorney for review. This page is general California information for organizing your own documentation before you speak with a licensed California attorney. For a referral, use the State Bar of California Lawyer Referral Service.

Direct answer (first 80 words): If you believe a dental procedure caused nerve damage in California, your first priorities are clinical — continued evaluation and care from a qualified oral and maxillofacial surgeon or neurologist. In parallel, request your complete dental records in writing under HIPAA, preserve all imaging (panoramic x-rays, CBCT scans), keep a dated symptom log, and contact a licensed California attorney through the State Bar Lawyer Referral Service well before any statute-of-limitations deadline under CCP §340.5.

What this page does (and does NOT) cover

This page is general California informational documentation guidance for people who believe they have experienced nerve injury — typically to the inferior alveolar nerve, the lingual nerve, or, less commonly, the mental nerve or buccal nerve — after a dental procedure such as third molar (wisdom tooth) extraction, mandibular dental implant placement, root canal therapy on a mandibular molar, local anesthetic injection, or restorative work involving the lower jaw.

The page focuses on three things only:

What may have happened, in California medical / clinical terms

Understanding the clinical landscape is not a substitute for medical advice from your treating providers. But many patients arrive at a lawyer consultation unable to describe what happened, which slows everything down. Here is a general framework so you can ask better questions of your next physician and read your own records more clearly.

The two nerves most commonly implicated in dental nerve injury are the inferior alveolar nerve (IAN) and the lingual nerve. Both are branches of the mandibular division of the trigeminal nerve (cranial nerve V).

The inferior alveolar nerve runs inside the mandible (lower jaw bone), through a bony canal, and exits at the mental foramen near the chin. It carries sensation from the lower teeth, lower lip, and chin. Injury typically presents as numbness, tingling, or altered sensation in the lower lip and chin on the affected side. It can happen during third molar removal (especially when the roots are close to or in contact with the canal), during implant placement (drilling or implant placement into the canal), during inferior alveolar nerve block injection, or during endodontic (root canal) procedures on lower molars (extrusion of irrigant or filling material into the canal).

The lingual nerve runs along the medial side of the mandible near the lower wisdom tooth socket and carries sensation and taste from the front two-thirds of the tongue. Injury typically presents as numbness or altered sensation of the tongue on the affected side, sometimes with altered or lost taste. It is most often associated with third molar surgery, particularly with lingual retraction or with certain surgical approaches.

Nerve injuries are clinically categorized using systems such as Seddon's (neurapraxia, axonotmesis, neurotmesis) and Sunderland's (Grades I–V). In dental contexts, you will also see terms such as paresthesia (altered sensation), hypoesthesia (decreased sensation), anesthesia (absent sensation), dysesthesia (unpleasant abnormal sensation), and hyperalgesia (heightened pain response). Many transient injuries resolve within days to weeks; injuries that persist beyond several months are less likely to fully resolve without intervention.

Time matters clinically as well as legally. Many oral and maxillofacial surgeons specializing in microneurosurgical repair recommend evaluation within a defined window after injury, because surgical repair of certain nerve injuries is generally more successful earlier rather than later. Delays in clinical evaluation can affect both your medical outcome and the completeness of the documentation later needed by any attorney.

Common questions to ask your next physician — typically an oral and maxillofacial surgeon with microneurosurgery experience, or a neurologist familiar with trigeminal nerve injuries — include:

You do not need to understand all of this to organize your records. But the more accurately you can describe your own symptoms in writing, the better.

• Which nerve do you believe is affected, and what is the suspected mechanism of injury?
• Is the injury most consistent with stretch, compression, partial transection, or complete transection?
• What imaging would you recommend (CBCT, MRI neurography, etc.)?
• Is microsurgical repair an option, and within what time window?
• What is the clinical prognosis if I pursue conservative management versus intervention?
• What documentation should I obtain from my prior provider?

What the California legal framework looks like (informational only)

This section is informational only. It is not a strategic assessment of your situation, and it does not estimate the value or strength of any individual claim. A licensed California attorney can apply these statutes to your facts.

Statute of limitations — CCP §340.5. California Code of Civil Procedure §340.5 governs the statute of limitations for professional negligence by a healthcare provider, including a licensed dentist acting within the scope of dental practice. As a general rule for adult patients, the statute is the earlier of: (a) three years from the date of injury, or (b) one year from the date the patient discovered, or through the use of reasonable diligence should have discovered, the injury. Different rules apply to minors. There are also tolling provisions for fraud, intentional concealment, or the presence of a foreign body with no therapeutic purpose. The statute can be complex in nerve-injury cases because the date of injury and the date of discovery may be different, and the date of discovery is itself a fact question. Because of this complexity, deadlines should be treated with urgency. See the official statute at the California Legislative Information website.

90-day notice of intent — CCP §364. California Code of Civil Procedure §364 requires a plaintiff to give a healthcare provider at least 90 days written notice of intent to commence an action based on professional negligence before filing the action. The notice has specific content requirements. If proper notice is served within the last 90 days of the applicable statute of limitations, §364(d) provides a 90-day extension. Mishandling this notice can cause real problems. This is one of the more common reasons attorneys want to be retained early.

MICRA non-economic damages cap — Civil Code §3333.2 as amended by AB 35. California's Medical Injury Compensation Reform Act (MICRA) places a statutory ceiling on non-economic damages in professional negligence actions against healthcare providers. AB 35, effective January 1, 2023, replaced the long-standing $250,000 cap with new tiered caps: for non-death cases, the cap began at $350,000 in 2023 and is adjusted annually under the statutory schedule; for wrongful-death cases, the cap began at $500,000 in 2023 and is also adjusted annually under the statutory schedule. The exact current figures depend on the year the cause of action arose and on the statutory adjustment schedule. These are statutory maximums only and are not a value-estimate of any individual matter. A licensed California attorney can explain how the current cap applies to your specific facts.

General personal-injury statute — CCP §335.1. California Code of Civil Procedure §335.1 sets a general two-year statute of limitations for personal-injury actions. Most dental-malpractice claims are governed by §340.5 rather than §335.1, but related theories (such as a battery claim arising from a procedure performed without consent) may have different limitation periods.

Business and Professions Code — Dental Practice Act. The practice of dentistry in California is governed by Division 2, Chapter 4 of the Business and Professions Code (the Dental Practice Act), and licensees are regulated by the Dental Board of California (dbc.ca.gov). Statutes and regulations govern recordkeeping, informed consent, scope of practice, and standards of conduct. Violations can be the subject of Board discipline, separate from any civil matter.

Informed consent. California recognizes a "reasonable patient" standard for informed consent in many contexts, derived from Cobbs v. Grant (1972) 8 Cal.3d 229. A patient is generally entitled to information about material risks, alternatives, and the consequences of declining treatment. In a procedure with a known and disclosed risk of nerve injury, the existence of a signed informed-consent form does not automatically resolve a claim, but it is part of the analysis.

Products liability and other theories. If a device (such as a specific dental implant), a material, or an instrument is implicated, products-liability principles may also be relevant. These analyses are fact-intensive and are not addressed here.

This page does not estimate the value or strength of any individual claim. It cannot. Each case turns on records that we do not have, on standard-of-care opinions that only retained experts can provide, and on legal analysis that requires a licensed California attorney evaluating your specific facts.

Records to organize right now

Whether or not you ultimately pursue a civil claim, organizing your records now protects you. Records are easier to obtain shortly after the event than months later. Memories fade. Imaging files get archived or deleted. Personnel turn over at clinics.

From the dental practice that performed the procedure, request in writing:

Request format and HIPAA. Under HIPAA (45 CFR §164.524), patients have a right to access their own protected health information. The request should be in writing, dated, signed, and specific about what you want and the format (paper, electronic, original DICOM imaging files). California providers are generally required to respond within statutory timeframes; California's records-access laws operate alongside HIPAA. Keep a dated copy of every request you send. If you ask for records by phone or in person, follow up the same day in writing (email is acceptable) to create a record.

From any subsequent providers:

From you, written contemporaneously:

Store everything in one organized folder — digital or physical — so that if you do meet with an attorney, you can hand them a clean, complete package on the first visit. A clean intake speeds everything up.

• The complete dental chart, including all clinical notes
• All progress notes, treatment notes, and post-operative notes
• The signed informed-consent form for the procedure
• The operative or procedure note from the day of the event
• Post-operative instructions provided to you (written and electronic)
• All radiographs (x-rays): periapicals, panoramics, bitewings, and any CBCT (3D cone-beam) scans, in original DICOM format if possible
• Itemized billing and insurance claim records
• Pharmacy records or prescription records associated with the procedure
• Anesthesia records if applicable
• Any incident reports, internal correspondence, or referral letters related to the complication, to the extent maintained in your chart
• Second-opinion notes from another dentist or oral and maxillofacial surgeon
• Neurology consultation notes
• Imaging from any subsequent CBCT or MRI neurography studies
• Any sensory testing results (light touch, two-point discrimination, pin-prick, brush stroke)
• Treatment notes from microsurgical or pain-management consultations
• A chronological symptom log, written by date, in your own words: which areas are numb or altered, what the sensation feels like, how it changes throughout the day, what worsens or improves it, and how it interferes with eating, speaking, sleeping, working
• Photographs of any visible asymmetry, swelling, or skin/mucosal changes, dated
• A timeline document: date of procedure, date you first noticed the symptom, what you were told that day, every contact with the office, every appointment, every referral
• A list of every person who has observed or experienced the change (spouse, family, coworkers), with contact information
• Notes about any conversations with the original dental office staff, with dates and names

Step-by-step: what to do in the next 7-90 days

The following is a general phased framework. It is not legal advice. It is not a treatment plan. Your specific situation may require a different sequence and a different pace, and clinical care decisions belong with your treating providers.

Days 0–7: stabilize and document.

Days 7–30: clinical evaluation and second opinion.

Days 30–90: legal consultation while continuing clinical care.

Across all phases: do not.

• Continue all clinically necessary care. If you have not yet been evaluated by a specialist about the nerve symptom, ask your primary care physician or dentist for a referral to an oral and maxillofacial surgeon with experience in nerve injury, or to a neurologist.
• Begin a daily symptom log today, even if the entries are short.
• Photograph visible findings, dated.
• Make a written request for complete records from the original dental practice. Send it by a method that creates a delivery record (certified mail, email with read receipt, or in-person delivery with a dated signed receipt).
• Do not sign any release, settlement, or refund agreement from the original practice without first having a licensed California attorney review it.
• Do not post about the situation on social media. Posts can be discoverable and can be misinterpreted.
• Obtain a second opinion. The earlier this happens, the more complete the documentation. Some nerve repair options are time-sensitive.
• Continue the symptom log.
• Once you have records, store them in one organized digital folder, file-named clearly.
• Keep a running list of every out-of-pocket expense and every missed-work date.
• Contact the State Bar of California Lawyer Referral Service to find a panel attorney who handles dental malpractice or personal injury. Many California dental-malpractice attorneys offer a free initial consultation and work on a contingency-fee basis; this is informational only.
• If your symptoms began many months ago, do not wait — the statute of limitations under CCP §340.5 can be short and depends on the date of injury and date of discovery. Speak with an attorney sooner rather than later.
• Bring your organized documentation package to the consultation.
• Do not, on your own, send a demand letter to the dental practice, sign any settlement or release from the dental practice's insurer, or engage in any compensation negotiation. These steps can prejudice a future case.
• If you decide to file a complaint with the Dental Board of California, you can do so at any time. It is a regulatory matter, independent of any civil matter.
• Do not give a recorded statement to any insurance adjuster (the dental practice's malpractice insurer, or otherwise) without first speaking with an attorney.
• Do not sign a release of liability in exchange for a refund of your dental fees. A refund is generally a small fraction of the overall picture, and signing a release in exchange may foreclose options you do not yet understand.
• Do not delete texts, emails, voicemails, or social-media messages related to the procedure or the symptom — even if they seem embarrassing or unfavorable. Preserve them.
• Do not assume the original practice's reassurances are clinically accurate. Get an independent opinion.

Filing a Board complaint (informational)

The Dental Board of California regulates the practice of dentistry in California. Patients who believe a dentist's conduct fell below professional standards can file a written complaint with the Board. The Board investigates complaints and can impose discipline ranging from informal correspondence to license revocation. Information and the complaint form are available at dbc.ca.gov.

A Board complaint is not a civil lawsuit. The Board does not award damages, does not order refunds, and does not represent the patient. The Board's role is regulatory — to determine whether the licensee complied with the Dental Practice Act. Many people file a Board complaint and also consult a civil attorney, on parallel tracks.

If anesthesia was provided by an anesthesiologist or a physician, complaints involving that physician's conduct fall under the Medical Board of California rather than the Dental Board. If a dental assistant or registered dental hygienist's conduct is implicated, separate licensing programs apply within the Dental Board's structure.

The documentation you have organized for an attorney consultation can usually also support a Board complaint. Board complaint forms typically ask for: the licensee's name and license number, the address of the practice, the dates of the events, a narrative of what happened, a list of witnesses, and supporting documents.

A Board complaint does not toll (pause) the statute of limitations for a civil matter under CCP §340.5. Filing a Board complaint and waiting for the Board to complete its investigation is not a substitute for protecting your civil deadlines. If you intend to pursue both tracks, talk to a California attorney about timing.

How a Lawyer-Ready Summary can help with documentation

When you sit down with a California attorney for a free consultation, the most useful thing you can bring is a clean, organized summary — a single document that lays out who was involved, what happened, when, and what records exist. Attorneys evaluating a possible dental-malpractice or personal-injury matter typically have limited time in an initial consultation. Walking in with twelve loose folders and a fragmented memory is normal, but it is not optimal.

Our free Lawyer-Ready Summary toolkit helps you organize your own documentation into a structured one-page-plus summary, with a parties block, a chronological timeline, an evidence inventory, and a notes-for-counsel block. It does not analyze your case, does not predict outcomes, does not provide legal advice, and does not include any drafting of letters or demands. It is a documentation-organization tool, free, for your own use before you speak with a licensed California attorney.

What it helps you do, specifically for a nerve-injury matter:

Organize My Injury Documentation

After organizing your documentation, the next step is review by a California attorney. xCounsel can route your organized matter to a California attorney for review, and the State Bar of California Lawyer Referral Service is another official way to find a California-licensed attorney, including attorneys who handle dental-malpractice and personal-injury matters.

• Build a clear timeline from pre-procedure consult through the procedure, the immediate post-op period, and every follow-up
• Inventory every record you have requested, every record you have received, and what is still outstanding
• List every provider involved (primary dentist, oral surgeon, anesthesia provider, follow-up specialists, neurologist, second-opinion dentist) with contact information
• Capture your own contemporaneous symptom narrative in a form that is easier for an attorney to read than a stream of scattered text messages
• Identify gaps in documentation early, so that you can request the missing records before a consultation rather than after

When to talk to a California attorney

The honest answer for most nerve-injury fact patterns is: sooner than you think.

The statute of limitations under CCP §340.5 can be as short as one year from the date you discovered or reasonably should have discovered the injury. CCP §364 requires 90 days notice of intent to sue before filing. Microsurgical repair, when appropriate, often has time-sensitive clinical windows. The Dental Board's complaint process is separate but not a substitute. And the original dental practice may approach you with a release-for-refund offer at any point — possibly soon.

You do not need to know whether you have a "case" to talk to an attorney. That is what the consultation is for.

To find a California attorney who handles dental-malpractice or personal-injury matters:

When you contact an attorney, be brief and clear: the date of the procedure, the procedure performed, the nerve symptom (lingual / inferior alveolar / mental), the date you first noticed the symptom, the current status, and that you have organized records ready to share. A focused intake call works better than a wandering one.

If a particular attorney declines your matter, that is not an answer about your situation — it is an answer about that attorney's caseload and intake criteria. The State Bar referral can connect you to others.

• State Bar of California Lawyer Referral Service — the official certified referral service of the State Bar. You can describe your situation and receive a referral to a panel attorney. Many California dental-malpractice and personal-injury attorneys offer a free initial consultation and work on a contingency-fee basis; this is informational only and not a promise that any particular attorney will accept your matter or take it on a contingency basis.

Common mistakes that hurt documentation

These are general patterns that, in a representative situation like this one, complicate later legal evaluation.

1. Talking to the dental office's malpractice insurance adjuster without records and without counsel. Adjusters call early. Recorded statements made before you have your records, before you have a clinical second opinion, and before you have spoken to a California attorney can lock in problematic narratives.

2. Signing a release in exchange for a fee refund. Refunds are commonly offered after a complication. Releases attached to those refunds can foreclose larger claims. Have any release reviewed by a licensed California attorney before signing.

3. Deleting texts, voicemails, or emails because they feel embarrassing. Preserve everything. Awkward, inconsistent, or emotional messages are still better preserved than missing.

4. Missing the CCP §364 90-day notice or the CCP §340.5 statute of limitations. Both deadlines are unforgiving. They are the most common reason cases that might otherwise have been viable cannot proceed.

5. Posting about the situation on social media. Posts may be discoverable and may be characterized in unhelpful ways. If you need to talk, talk to a trusted person privately, not online.

6. Failing to request original DICOM imaging files. A printed x-ray copy is not the same as the original DICOM file. Specify DICOM in your records request so that future specialists can re-read the imaging in proper diagnostic format.

7. Waiting "to see if it goes away" past the discovery window. Hope is reasonable. But the discovery rule under §340.5 can start running earlier than you expect. Talking to an attorney does not commit you to filing anything.

8. Relying only on the original practice for follow-up. Some clinical findings are easier to document independently. A second opinion creates an independent record that does not depend on the original practice's notes.

9. Discarding pharmacy bottles, post-op packets, or appointment cards. Small physical items can corroborate a timeline.

10. Skipping the symptom log because the symptom feels constant. A daily log creates a contemporaneous record that is much more credible than a memory reconstructed months later.

Frequently asked questions

Is lingual or inferior alveolar nerve injury after wisdom tooth extraction always considered malpractice in California?

No. Some degree of nerve injury is a recognized risk of certain dental procedures, particularly third molar extractions and mandibular implant placement, and a known risk that was properly disclosed and informed-consented to is not, by itself, malpractice. Whether a specific injury rises to the level of a viable claim under California law depends on the standard of care, the procedural choices made, the imaging available before surgery, and the post-injury management. This page does not estimate the value or strength of any individual claim. A licensed California attorney evaluating your records is the appropriate next step. The State Bar of California Lawyer Referral Service can help you find one.

How long do I have to act under California law?

California Code of Civil Procedure §340.5 generally sets the limit at three years from the date of injury or one year from when you discovered or reasonably should have discovered the injury, whichever comes first, for dental malpractice claims involving adults. Different rules apply to minors. CCP §364 also requires 90 days written notice of intent to sue a healthcare provider before filing, which can affect timing. Because these deadlines are strict and fact-dependent, treat them with urgency and consult a California attorney through the State Bar Lawyer Referral Service well before any deadline approaches.

Should I file a complaint with the Dental Board of California?

Filing a complaint with the Dental Board of California is a regulatory process — the Board investigates licensee conduct and may impose discipline. It is separate from any civil matter and does not obtain monetary recovery for an individual. Many people file a Board complaint and also consult an attorney about a civil matter, but the two tracks are independent. The Board's complaint form and process are available at dbc.ca.gov. Documentation you organize for your attorney consultation can usually also be used to support a Board complaint.

Should I sign anything the original dental office gives me?

Be cautious. Some offices, after a complication, ask patients to sign settlement releases, refund-in-exchange-for-release agreements, arbitration waivers, or revised consent forms. Signing a release can extinguish legal rights you may not yet understand. Before signing any document beyond standard treatment records release, have a licensed California attorney review it. Standard HIPAA records-release authorizations to forward your own records to a new provider or to yourself are different in nature, but if you are unsure whether a document is a records release or a liability release, do not sign it until you have legal review.

What records should I gather first?

Start with: the full dental chart and treatment notes, every x-ray and any CBCT (3D cone-beam) scan from before and after the procedure, the signed informed-consent form, the operative note, post-operative instructions, billing and insurance records, any correspondence with the office about the complication, and a chronological symptom log you write yourself. Also gather any second-opinion records, neurology or oral-surgery referral notes, and photographs of visible swelling or asymmetry. Request records in writing under HIPAA (45 CFR §164.524). California providers generally must respond within statutory timeframes.

Does xCounsel handle this kind of case?

No. xCounsel is not a law firm and does not itself represent you in dental-malpractice, medical-malpractice, personal-injury, plastic-surgery harm, or family-law matters, though for these matters it helps you organize your records and routes your matter to a California attorney for review.
