If your lower lip or chin stays numb after the local anesthetic should have worn off, contact the dentist or oral surgeon who treated you. Persistent numbness, tingling, or burning after a lower wisdom tooth extraction, dental implant, or root canal can be a sign of an inferior alveolar nerve injury. In Florida, a dental malpractice claim may arise when a provider falls below the accepted standard of care and that failure causes or worsens the injury.
What is the inferior alveolar nerve?
The inferior alveolar nerve runs through a channel inside the lower jaw called the mandibular canal. It carries sensation from the lower teeth. One of its branches, the mental nerve, supplies sensation to the lower lip and chin. Symptoms can affect one side of the lower face. Numbness or altered taste affecting the tongue may point to a different nerve, the lingual nerve.
Which dental procedures can injure the inferior alveolar nerve?
-
Lower wisdom tooth removal. The roots of an impacted lower wisdom tooth can lie close to the mandibular canal. The nerve can be injured during removal, particularly when the roots and canal are close together.
-
Dental implants in the lower jaw. A drill or implant can enter the canal or put pressure on the nerve. The planned implant position, depth, and available bone matter when evaluating what happened.
-
Root canal treatment on lower teeth. If instruments or filling materials extend beyond the root tip near the canal, they can injure or irritate the nerve.
-
Local anesthetic injections. An inferior alveolar nerve block intentionally produces temporary numbness. In some cases, altered sensation persists after the expected anesthetic effect.
What does inferior alveolar nerve damage feel like?
You may have reduced or absent feeling in the lower lip or chin, pins and needles, burning, or electric-shock sensations. Light touch may feel painful. Some people notice the change because they repeatedly bite their lower lip or have trouble sensing food or liquid on it. Recovery varies with the type and severity of the injury. Some symptoms improve over time, while others can persist.
If the numbness lasts beyond the timeframe your provider gave you, or if altered sensation or pain is worsening, call the dental office promptly. Tell them when the symptoms started, exactly where you feel them, and whether they are changing. Ask whether you need an examination or a referral to an oral and maxillofacial surgeon with experience evaluating nerve injuries. When an implant may be pressing on the nerve, timely evaluation can affect treatment options.
When can a dental nerve injury be malpractice in Florida?
Nerve injury is a recognized risk of some dental procedures and can occur even when the provider uses reasonable care. A malpractice review asks what a reasonably prudent provider would have done under similar circumstances and whether a departure from that standard caused the injury or made it worse. A qualified expert typically reviews the imaging, treatment records, and follow-up.
Before the procedure
Did the provider assess how close the tooth roots or planned implant were to the mandibular canal? Would additional imaging, referral, or an alternative procedure have been appropriate? For some high-risk lower wisdom teeth, an oral surgeon may consider a coronectomy, which removes the crown and leaves the roots in place. The need for three-dimensional imaging depends on the clinical circumstances. A cone beam CT scan is not routinely required for every lower wisdom tooth extraction.
During the procedure
Did the provider use an appropriate surgical technique and control the depth and position of the drill or implant? For example, a post-treatment scan showing an implant extending into the mandibular canal may give an expert a specific finding to compare against the preoperative images, planned depth, and location of the patient's symptoms.
After the procedure
When did the provider learn about the numbness? Did the provider document where sensation had changed, evaluate the likely cause, and arrange follow-up or a referral when appropriate? If the claim concerns a delayed response, an expert may need to determine whether earlier evaluation or treatment likely would have changed the outcome.
Does signing a consent form prevent a claim?
A signed form can be important evidence in an informed-consent dispute. Florida law considers what the provider disclosed about the procedure, substantial risks, and medically acceptable alternatives. Even if the provider adequately disclosed the risk of numbness, the quality of the planning, procedure, and follow-up can still be evaluated separately.
What records can help evaluate a dental nerve injury claim?
-
Pre- and post-procedure images. Request copies of X-rays and any cone beam CT scans, including original digital image files if available.
-
Dental records. Request the treatment plan, consent forms, procedure notes, and any implant planning records or referrals.
-
Follow-up communications. Save portal messages and emails. Note when you called, what you reported, and what the office told you.
-
Specialist findings and expenses. Keep examination reports, sensory testing results, bills, and records of missed work. Write down how symptoms affect daily activities such as eating or drinking.
Depending on the evidence, recoverable damages may include reasonable treatment costs, lost income, and pain and suffering attributable to the injury.
How long do you have to file a Florida dental malpractice lawsuit?
Florida generally gives patients two years from the incident or from when it was discovered or reasonably should have been discovered. A separate four-year statute of repose generally runs from the incident, subject to statutory exceptions. The deadline can depend on what you knew and when, as well as how the presuit rules apply. Waiting to see whether the numbness becomes permanent can leave less time to investigate a claim.
Florida also requires a presuit investigation, corroboration through a verified written opinion from a qualified expert, and notice to each prospective defendant before suit. The notice generally begins a 90-day presuit screening period. An attorney can calculate the applicable deadlines and assess the records while you continue receiving care.
Frequently asked questions
Can lower lip or chin numbness after dental work be permanent?
Yes. Some nerve injuries improve, and others cause lasting loss of sensation or nerve pain. A specialist can examine the affected area, document changes over time, and discuss the outlook based on the findings.
Can I have a claim if my dentist referred me to a specialist?
A referral is one part of the timeline. The review may consider how quickly the referral was made, what the specialist found, and whether any earlier treatment decision or delay caused additional harm.
