How to Stop Clenching Your Jaw, Day and Night

Published October 2026 · Updated October 2026

How do I stop clenching my jaw?

Start by catching it. It depends on when you clench: daytime clenching is a habit you can retrain with a simple posture check, repeated until it is automatic. Nighttime clenching is harder because you are asleep, so the fix is a wind-down routine that sends the muscle to bed already relaxed. For most people, awareness plus an evening routine ends the cycle within a few weeks.

The lips-together, teeth-apart rule

Your teeth should only touch when you eat. Set three or four phone reminders a day: lips closed, teeth slightly apart, tongue resting lightly on the roof of your mouth. Every time the reminder fires, you will likely discover you were clenching, which is the whole point. Within two to three weeks, the new resting position starts holding on its own.

Find your triggers

  • Focused work: laptops, deadlines, games. Your jaw mirrors your effort.
  • Driving: traffic tension goes straight to the jaw.
  • Stress spikes: hard conversations, notifications, doomscrolling.
  • Chewy foods and gum: gum trains the exact muscle you are trying to relax.

Once you know yours, the trigger itself becomes the reminder to unclench.

The evening wind-down for your jaw

Night clenching undoes daytime progress, so give the muscle ten calm minutes before bed:

  • Warm compress for two to three minutes
  • Steady pressure along both sides of the jaw for five to eight minutes. The Voirelle Hush does this hands-free: eight rollers press both sides at once while you sit still.
  • One slow open-stretch, five seconds, repeated five times
  • Teeth apart as you fall asleep

What if you grind your teeth at night?

Grinding, where the teeth slide against each other, is the noisier cousin of clenching, and it wears teeth down. A dentist-fitted night guard protects the teeth, but it does not relax the muscle, so pair it with the evening routine above rather than relying on it alone. If teeth are chipping or flattening, get checked in person.

The bottom line

Daytime clenching is a habit you can train away with the lips-together, teeth-apart check. Nighttime clenching needs a ritual, because willpower does not work while you sleep. Cover both ends of the day and the muscle finally gets the rest it has been asking for.
