What is bruxism or teeth grinding?
Bruxism means grinding or clenching your teeth. It can happen while you are awake or asleep, and you may notice the effects before you notice the habit. A dental examination can help identify tooth wear, damage, and other possible causes of jaw discomfort.
How can I tell if I grind my teeth?
Possible signs include worn or chipped teeth, tired jaw muscles, morning jaw soreness, and sensitivity. A sleeping partner may hear grinding. These signs do not prove bruxism: decay, a cracked tooth, and other conditions can cause similar symptoms. Start with a dental examination rather than diagnosing the problem yourself.
Does a night guard stop teeth grinding?
A professionally fitted guard can help protect teeth from grinding forces. It does not guarantee that grinding will stop. The appropriate approach depends on your symptoms, existing restorations, and whether clenching occurs during the day or at night. Our bruxism care page explains how we evaluate tooth grinding and discuss protection.
What can I do about daytime clenching?
Notice when your teeth are touching during concentration or stress, and discuss that pattern with your dentist. Keeping a short record of when symptoms occur can make your visit more useful. If symptoms began after a medication change, tell your prescriber and dentist; do not stop prescribed medication on your own.
When should I have grinding symptoms checked?
Arrange an evaluation for repeated jaw soreness, new sensitivity, chipped teeth, or damage to a filling or crown. If a tooth hurts when you chew, our guide to common causes of tooth pain explains why an examination matters. Discuss snoring or breathing concerns during sleep with your medical clinician as well.

Are You a Nighttime Tooth Grinder? Here's How To Tell—And What to Do About It
Teeth grinding is a problem that affects nearly one in ten individuals, yet many of us don’t even realize we’re doing it. And that’s a problem given just how harmful it can be to our health. Here’s how to find out if you grind your teeth when you sleep—and why it’s something you shouldn’t ignore.
Teeth grinding, or bruxism, is a common condition that often goes unnoticed because it typically occurs during sleep. Many patients are unaware it’s happening until signs of damage begin to appear — sometimes years later.
Persistent grinding places excessive forces on teeth, dental restorations, jaw joints, and the muscles of the face and neck. Over time, this can contribute to tooth wear, fractures, jaw discomfort, headaches, and changes in bite function. Left unaddressed, bruxism can quietly undermine otherwise healthy teeth.
For a clear, accessible overview of how teeth grinding occurs during sleep — and why it’s difficult to recognize without professional evaluation — this article provides a helpful explanation:
