How can I tell if I grind my teeth at night with no one to hear?

Go by the signs on waking — a tight jaw, headaches, sensitive teeth — and by the dental exam, which reveals the characteristic wear patterns.

Does stress cause bruxism?

Stress and anxiety are recognized aggravating factors, especially for daytime clenching. They aren't the only cause, but managing them often helps.

Can bruxism go away on its own?

It can vary over time, but if it persists, the wear on your teeth won't repair itself. Better to have it assessed than to wait.

Can children have bruxism?

Yes, bruxism is common in children and often resolves with growth. Dental follow-up monitors the wear and reassures parents.

Which professional should I see?

Your dentist is the first point of contact: they diagnose bruxism, assess the teeth and TMJ, and propose the appropriate care.

Night grinding: 6 signs you should get checked

June 16, 2026 · 5 min read

Sleep bruxism — grinding or clenching your teeth at night — is often silent: you don't notice it yourself. But your body leaves clues: a sore jaw on waking, morning headaches, worn or sensitive teeth. Spotting these signs early lets you protect your teeth before the wear sets in.

Why you don't notice you're grinding

Bruxism happens mostly during sleep, outside our awareness. Many people learn about it from a partner who hears the grinding, or from their dentist, who spots the wear on the teeth. That's why the indirect signs — on waking and through the day — are so useful for catching it.

The 6 signs that should get your attention

If several of these ring true, it's worth raising with your dentist:

A stiff, tired, or sore jaw when you wake up
Morning headaches, especially at the temples
Worn, flattened, chipped, or increasingly sensitive teeth
Grinding sounds your partner hears at night
Pain or clicking in the jaw joint (TMJ)
A more square-looking jawline — a sign of an enlarged masseter

Sleep bruxism or daytime clenching?

There are two forms. Sleep bruxism is involuntary and nighttime; daytime clenching is often tied to stress or concentration — you clench silently, sometimes at a screen. The two can coexist, and care is adjusted to the pattern.

What bruxism does to your teeth if nothing is done

Over time, repeated force wears the enamel, flattens the tips of teeth, causes cracks, and can weaken fillings and crowns. Sensitivity rises, and muscle tension sustains TMJ pain and headaches. The earlier you act, the more you prevent this damage — which is itself irreversible.

When to see a dentist — and what can be done

If you recognize several signs, an exam confirms the bruxism and assesses the wear. Depending on your case, options range from a night guard, which protects the teeth at night, to neuromodulators (Botox®), which reduce the muscle's force at its source — sometimes both together. The approach is chosen with you.
