Plenty of people grind their teeth without knowing it. The habit usually happens during sleep, so the first clue is often a sore jaw in the morning. Sometimes a bed partner hears it first. Dentists call it bruxism, and it can range from mild and occasional to frequent enough to wear and damage teeth.
This guide covers what teeth grinding is, why it happens and the signs to look out for. It also explains what a dentist may suggest and some everyday habits that may help. The aim is to give you enough background to have a useful conversation at your next dental visit.
