Seizures and dental injuries

Although most people do not usually hurt themselves during a seizure, sometimes seizures can cause injuries. If someone falls in a seizure, they may loosen or crack a tooth and will probably need to see a dentist quickly so the tooth can be repositioned or repaired. 

If someone knocks out a tooth, and you feel confident to help, some quick action may mean that the tooth can be saved and replaced. Only do this if the person is otherwise well enough after the seizure.
How to help

• Try to find the tooth. Pick it up by the crown, and do not touch the root.
• If the tooth is dirty, clean it by rinsing it in milk or running it under water. Do not scrub it.
• Put the tooth back into the socket as quickly as possible.
• Ask the person to bite down on a clean tissue or handkerchief to keep the tooth in place. The person should see a dentist as soon as possible.
• If you are not able to put the tooth back in its socket, try to keep it wet, if possible by putting it in some milk.
