Tooth-brushing-induced epilepsy.

A case report of a 12-year-old male with tooth-brushing-induced epilepsy is presented. The partial elementary seizures began several weeks after placement of a palatal expansion appliance which led to local irritation of the upper gums. Although other oral stimulation occasionally precipitated the seizures, they were consistently induced by tooth brushing. The case is another example of how specific stimuli can trigger epileptic seizures.
