Toothbrush epilepsy – how brushing your teeth can trigger a seizure

24th May 2018

In our recent blog post we discussed common and uncommon triggers for epilepsy, however, one of the rarer triggers is the action of brushing the teeth – toothbrush epilepsy. It’s exactly as it sounds, seizures triggered by the simple act of brushing your teeth. It was an Australian research team who first described the possibility back in 2007, since then it has become more understood. It can also be triggered using a traditional or an electric toothbrush. This is one of many of the reflex epilepsies.

What is reflex epilepsy?

Reflex epilepsy is when seizures are provoked by external stimulus. Reflex epilepsy is very uncommon, although they do a garner a large amount of scientific interest as there is much still to be learned.

Other interesting reflex epilepsies include reading epilepsy and hot water epilepsy

Why does it happen?

The cause of ‘toothbrush epilepsy’ is believed to be injury in the part of the brain responsible for hand movement, speech and mouth movements, such as chewing. It’s thought that the rhythmic action of brushing the teeth can trigger a seizure by exciting that part of the brain. It’s this persistent rhythm that makes it much more likely to trigger a seizure than other acts, such as chewing or talking.

Much is still unknown about toothbrush epilepsy, reports have suggested that brushing certain parts of the mouth or using a different hand can make it more likely to have a seizure.

What can I do about it?

With most types of reflex epilepsy, it’s recommended to avoid the trigger altogether. Of course, brushing your teeth is essential for good oral hygiene and it’s important that you’re still able to do so. It’s possible that the seizures may be controlled by medication. Using an irregular brushing pattern may also help, as it’s believed that it’s the rhythmic brushing that trigger the seizure, although this is often a difficult habit to get into.
