title: Unilateral hypoglossal nerve palsy due to infected molar: a rare entity.
abstract: Isolated hypoglossal nerve palsy is a rare condition. There are several causes that can be attributed to it. We present a case where a patient presented herself with pain in the left back tooth region, with unilateral left hypoglossal nerve palsy. All investigations were negative. The infected tooth was removed, and the patient had speech therapy and was actively rehabilitated. The isolated hypoglossal nerve palsy could have been due to the infected impacted tooth. Therefore, dentists presented with a case of isolated hypoglossal nerve palsy should consider the infected impacted tooth as the differential diagnosis.
