With multiples etiologies, these included trauma, tumor formation, idiopathic conditions, cerebral infarct, pseudobulbar palsy and viruses. FNP during dental treatment is very rare and can be associated with the injection of local anesthetic, prolonged attempt to remove a mandibular third molar and subsequent infection. We report a case of a 21 years-old black woman who developed a Bell's palsy after an impacted third molar surgery under local anaesthesia, present a FNP classified like a grade IV by the House-Brackmann's grading system. The treatment was based of prescription of a cytidine and uridine complex (NUCLEO CMP tm) one tablet twice per day and a close follow up.
