In the long-term, the friction can wear away at enamel and fracture fillings. Your dentist might call this bruxism, and it affects millions of adults. It can happen during the day or while you sleep. A few things may cause it:
- Stress and anxiety. They can trigger it, or make it worse.
- Teeth alignment. The way they line up may cause grinding.
- Medicines. Some antidepressants can lead to it.
- Sleep apnea. Treat the apnea and the grinding may end.
