Dental Nerve Distribution and Symptom Table
Use the table to describe the affected area precisely when requesting review after dental treatment.
Which dental nerve matches which area?
Dental nerve distribution and symptom table
| Nerve/pathway | Usual sensory area | Possible symptoms | Common dental context |
|---|---|---|---|
| Lingual nerve | Same-side tongue; contributes to taste through associated fibres. | Numbness, tingling, burning, altered touch, tongue biting or altered taste. | Lower wisdom-tooth surgery or, rarely, local-anaesthetic injection. |
| Inferior alveolar nerve | Lower teeth and, through the mental nerve, the same-side lower lip and chin. | Numbness, pins and needles, burning, electric pain or altered sensation. | Lower extraction, implant placement or material close to the mandibular canal. |
| Mental nerve | Lower lip and chin beyond its exit from the lower jaw. | A localised lower-lip/chin patch without tongue symptoms. | Implant, surgery or trauma near the premolar mental-foramen area. |
| Not a single peripheral distribution | Both sides, changing facial areas, motor weakness or broader neurological signs. | Diffuse numbness, weakness, facial asymmetry or symptoms outside a dental nerve map. | Requires broader urgent clinical assessment rather than self-diagnosis. |
Conclusion: Tongue/taste and lip/chin patterns should be recorded separately because they point to different anatomy and evidence.

Map quality, not just presence or absence
Record the side, precise boundary, whether sensation is absent, reduced, exaggerated or painful, and whether touch, temperature, taste, speech or eating is affected. Note when local anaesthetic should have worn off and whether the area changes. A clinician may perform repeatable neurosensory tests; home pinprick testing risks injury and is not recommended.
Distribution does not establish breach
A recognised nerve injury can occur despite reasonable planning and technique. Liability requires procedure-specific evidence about anatomy, imaging, consent, treatment and the response once symptoms appeared. Seek urgent clinical advice for new neurological symptoms, especially where they are accompanied by weakness, severe swelling, breathing difficulty or other systemic signs.
