Permanent Tongue & Lip Numbness After Wisdom Tooth Extraction: CT Nerve Injury Claims

When a patient undergoes a lower third molar (wisdom tooth) extraction or mandibular dental implant procedure in Connecticut, temporary numbness from local anesthesia should wear off within several hours. When numbness, tingling, or burning pain in the tongue, lower lip, or chin persists for days, weeks, or permanently, it signals trauma to the trigeminal nerve branches—most commonly the lingual nerve or the inferior alveolar nerve (IAN).

While oral surgeons and general dentists frequently claim that nerve damage is a "known risk" written on a consent form, informed consent does not excuse surgical negligence. In many Connecticut dental malpractice cases, permanent lingual nerve severing occurs because the practitioner violated established anatomical safety boundaries.

How Negligent Nerve Trauma Occurs

The lingual nerve runs along the lingual (tongue-side) plate of the mandible, providing sensation and taste to the anterior two-thirds of the tongue. The inferior alveolar nerve travels within the bony mandibular canal beneath the lower molar roots, supplying sensation to the lower lip, chin, and gum tissue.

Preventable surgical errors that cause permanent nerve damage include:

  • Failure to Perform Pre-Operative CBCT 3D Imaging: Extracting impacted lower wisdom teeth or placing dental implants near the mandibular canal without ordering a Cone Beam Computed Tomography (CBCT) scan when roots appear superimposed over the nerve canal on standard 2D panoramic X-rays.
  • Improper Lingual Flap Retraction & Bur Penetration: Allowing a high-speed surgical drill bur to penetrate the thin lingual cortical bone plate or failing to protect the lingual soft tissue during bone removal and tooth sectioning.
  • Blind Curettage or Aggressive Socket Instrumentation: Scraping deep within an extraction socket directly adjacent to an exposed inferior alveolar neurovascular bundle.
  • Failure to Refer to an Oral & Maxillofacial Surgeon: A general dentist attempting a complex, deeply impacted bony wisdom tooth extraction that requires specialist surgical skill.

Critical Window for Microsurgical Nerve Repair

Patients suffering from post-extraction anesthesia (complete numbness), paresthesia (altered tingling sensation), or dysesthesia (painful burning or electric-shock sensations) face a strict medical and legal timeline:

  • Immediate Neurosensory Testing: Any complete numbness lasting beyond 24–48 hours requires prompt evaluation and sensory mapping.
  • The 90-Day to 6-Month Microsurgery Window: If a lingual or inferior alveolar nerve has been severed or compressed, referral to a specialized microneurosurgeon must occur promptly—ideally within 3 to 6 months—before irreversible distal nerve degeneration and scar tissue formation (neuroma) prevent meaningful recovery.
  • Negligent Post-Operative Reassurance: A dentist who repeatedly tells an injured patient to "just wait a year for the feeling to come back" without referring them to a nerve repair specialist may commit an independent act of post-operative negligence by depriving the patient of timely surgical repair.

Evaluating a Connecticut Dental Nerve Injury Claim

Permanent lingual or inferior alveolar nerve damage is life-altering—interfering with speech, chewing, drinking, taste, and sleep. Attorney Richard T. Meehan Jr. personally inspects operative notes, pre- and post-operative panoramic and CBCT radiographs, and neurosensory records to evaluate Connecticut nerve trauma claims.
