Treating teeth grinding

Recommended treatments for bruxism (teeth grinding) include behavioural therapies and using mouth guards or mouth splints.

Other treatments, such as muscle relaxation exercises and sleep hygiene measures, may also help you manage your symptoms.



Mouth guards and mouth splints

If you grind your teeth while you're asleep, you may need to wear a mouth guard or mouth splint at night.

These even out the pressure across your jaw and create a physical barrier between your upper and lower teeth to protect them from further damage. They can also reduce any grinding noises you make at night.

Mouth guards are similar in appearance to those used in sports such as boxing. They're usually made out of bendy rubber or plastic and can be made by your dentist to fit your mouth. You'll usually have to pay for this type of custom-made dental appliance.

Mouth guards are also available to buy from your local pharmacist. However, it's unlikely to fit as well as one made by your dentist.

A mouth splint (also known as an occlusal splint or bite plate) is made from harder plastic and fits precisely over your upper or lower teeth.

Mouth splints are no more effective than mouth guards in reducing the symptoms of bruxism. They tend to last for years, whereas mouth guards usually last for less than a year. However, mouth splints are more expensive.

Although mouth guards and splints may help reduce muscle activity in your jaw at night, they're only able to control the condition, not cure it.
