Teeth grinding (also called bruxism) is often related to stress or anxiety. There are things you can do to help and treatments available from a dentist or GP.
Causes of teeth grinding
It’s not always clear what causes teeth grinding.
It’s often linked to:
- stress and anxiety – this is the most common cause of teeth grinding
- sleep problems like snoring, obstructive sleep apnoea (OSA) and sleep paralysis
- taking certain medicines, including a type of antidepressant known as selective serotonin reuptake inhibitors (SSRIs)
- smoking, drinking lots of alcohol and caffeine, and taking drugs like ecstasy and cocaine
Teeth grinding is common in children and teenagers, particularly during sleep. It often stops when they reach adulthood and their adult teeth have come through.
How to reduce teeth grinding
There are a number of things you can try that may help if you grind your teeth.
try to improve your sleep by going to bed at the same time every night, relaxing before bedtime and making sure your bedroom is dark and quiet
try jaw exercises, such as stretching the jaw muscles by opening your mouth as wide as you can and repeating it 10 times, once or twice a day
use an ice pack (or bag of frozen peas) wrapped in a towel for 20 to 30 minutes to help reduce jaw pain or swelling
have regular dental check-ups
do not smoke
do not drink too much alcohol
do not take drugs like ecstasy or cocaine
do not chew gum or eat hard foods if you have tooth or jaw pain
Symptoms of teeth grinding

Non-urgent advice: See a dentist if:

Treatments for teeth grinding
Treatment for teeth grinding is not always needed.
Treatments from a dentist
A dentist may recommend a mouth guard or mouth splint. These are worn at night and protect your teeth from damage. They can be made by a dentist to fit precisely over your upper or lower teeth
Mouth splints are more expensive than mouth guards but last longer.
Treatments from a GP
A GP can give you advice and recommend treatments for reducing stress.
