Bruxism is when you clench (tightly hold your top and bottom teeth together) or grind (slide your teeth back and forth over each other) your teeth.
Alternative Names
Teeth grinding and clenching
Causes, incidence, and risk factors
People can clench and grind without being aware of it during both the day and night, although sleep-related bruxism is often the bigger problem because it is harder to control.
The cause of bruxism is not completely agreed upon, but daily stress may be the trigger in many people. Some people probably clench their teeth and never feel symptoms. Whether or not bruxism causes pain and other problems may be a complicated mix of factors:
- How much stress you are under
- How long and tightly you clench and grind
- Whether your teeth are misaligned
- Your posture
- Your ability to relax
- Your diet
- Your sleeping habits
Each person is probably different.
