Please spare my teeth! Dental procedures and trigeminal neuralgia

The correct diagnosis of trigeminal neuralgia (TN) is still a far cry and the patients suffer from unnecessary dental procedures before getting the definite treatment. In this study, we evaluated, if the patients have undergone dental procedures for their misdiagnosed TN before receiving definite treatment for the same.

A total of 187 patients received GKRS for their TN (excluding secondary TN) in two institutes from 2010 to 2019. We did a retrospective analysis of these patients' primary complaints on a standard questionnaire.

One hundred and seventeen of the 187 patients responded. About 55.5% of patients had a toothache and 65.8% did visit a dentist for the pain. About 41.8% of patients underwent one dental procedure; 18.8% suffered from worsening of the pain while 8.5% received some partial improvement. About 19.6% also underwent root canal treatment while 6.8% had a nerve block. Mean of 1.6 teeth was extracted per person. About 71% of patients were satisfied with their Gamma Knife radiosurgery for TN at a median follow-up of 49 months.

There is a need for a better understanding of the disease among the dentists and the patients for the timely and correct treatment, without losing their teeth. The onus lies on neurosurgeons/neurologists disseminate knowledge regarding proper diagnosis and treatment modalities.
