Teeth Grinding (Bruxism): Signs, Damage & What Helps
Most people who grind their teeth have no idea they do it — it happens in deep sleep, and the noise bothers everyone except the grinder. The teeth, though, keep an honest record: flattened edges, morning jaw ache, and sensitivity that never quite explains itself.

Understanding it
What's actually happening
Bruxism is clenching or grinding outside of normal chewing — most commonly during sleep, often driven by stress, disturbed sleep or the way your teeth meet. Chewing forces are brief and cushioned; grinding forces are sustained, sideways and enormous — many times higher than eating ever produces.
Teeth aren't built for that. Over months and years the enamel edges flatten and chip, teeth become sensitive as dentine is exposed, jaw muscles ache from overnight overtime, and in long-standing cases the jaw joint itself starts clicking or tiring. The damage is slow, cumulative — and very preventable once it's recognised.
Common causes
What's usually behind teeth grinding (bruxism)
Stress & anxiety
The strongest everyday driver — clenching is how many bodies process a stressful day overnight.
Disturbed sleep
Bruxism clusters with snoring and poor sleep quality; they're worth mentioning together.
Bite misalignment
When teeth don't meet evenly, the jaw hunts for a comfortable position — sometimes by grinding.
Caffeine, tobacco & alcohol
All three, especially late in the day, measurably increase night grinding.
Daytime habits
Jaw clenching at a screen, nail biting and pen chewing train the same muscles.
Your action plan
What helps at home — and what shouldn't wait
Home care that genuinely helps
- Notice daytime clenching: teeth should only touch when chewing — lips together, teeth apart is the resting position
- Wind down caffeine after mid-afternoon; watch late alcohol
- A warm compress on the jaw muscles in the evening eases the ache
- Address stress honestly — it's the single biggest lever
- Avoid chewing gum and very hard foods while your jaw is sore
- Don't ignore a partner's report of night grinding — they're your best diagnostic tool
See a dentist if…
- Waking with jaw ache, facial muscle tightness or dull headaches
- Teeth that look flattened, chipped at the edges, or shorter than they used to
- Increasing sensitivity across many teeth
- Clicking, popping or tiring of the jaw joint
- Scalloped tongue edges or bite marks inside the cheeks

How we treat it
We confirm the pattern from the wear on your teeth, then protect them — typically with a custom-fitted night guard that absorbs the forces, plus repair of any teeth already chipped or worn down (bonding or crowns where needed) and a look at whether your bite is contributing.
Straight answers
Teeth Grinding (Bruxism) — your questions, answered
The morning tells you: jaw ache, temple headaches, or teeth that feel tender. Your dentist can see the story in flattened enamel edges — and a bed partner's report settles it. Most grinders are genuinely surprised.
