Trigeminal neuralgia
Trigeminal neuralgia (TN) causes sudden, severe, brief "electric shock" facial pain in trigeminal distribution, often triggered by light touch on trigger zones. First-line pharmacotherapy is carbamazepine or oxcarbazepine. Dental relevance: (1) TN pain can mimic tooth pain → risk of unnecessary irreversible dental treatment if not diagnosed correctly, (2) carbamazepine has MAJOR drug interactions with common dental antibiotics (macrolides) and antifungals (azoles), and (3) carbamazepine as an enzyme inducer can reduce efficacy of anticoagulants and other medications.
