If you wake up with a sore jaw, tight temples, or new tooth sensitivity, you may be dealing with teeth grinding at night. Many people do it without realizing it, until a partner hears the noise or a dentist spots early tooth wear. If you are searching for how to stop teeth grinding, the goal is twofold: protect your teeth now, and reduce the triggers that keep the habit going.
In this guide, you will learn how to stop teeth grinding with a practical bedtime routine, simple stress and sleep adjustments, and the right night guard for teeth grinding when extra protection is needed. If you are in Etobicoke, the team at FIFTH ST Dental can assess your bite, check for bruxism damage, and recommend a custom plan that fits your symptoms and your lifestyle.
Teeth Grinding at Night (Bruxism): How to Stop Teeth Grinding
Teeth grinding at night, also called sleep bruxism, is usually driven by the way your brain and muscles respond during sleep, not by willpower. Stress and anxiety can increase jaw muscle activity, and light or disrupted sleep may make clenching more likely. Common triggers include late caffeine, alcohol close to bedtime, nicotine, and some medications that affect the nervous system. In some people, airway or snoring issues can also be linked with teeth grinding at night, because the body briefly “arouses” to keep breathing steady.
If you want to know how to stop teeth grinding long-term, it helps to identify your personal triggers, then pair habit changes with dental protection when needed.
Signs You're Grinding Your Teeth While You Sleep
You do not need to “hear” yourself grinding to have it. These clues often show up in the morning, and they tend to repeat in predictable patterns over several days.
- Waking with jaw soreness or cheek muscle fatigue, especially after a stressful day.
- A dull temple headache or facial tightness that eases after breakfast, plus morning headaches and tight temples.
- Teeth that suddenly feel more reactive to cold, along with tooth sensitivity and worn edges you can see or feel.
- Fillings or crowns that chip, loosen, or feel high may signal cracked dental work and uneven bite pressure.
- A partner notices noise at night, or you wake with grinding sounds and cheek or tongue biting.
If this sounds familiar, a dentist can confirm bruxism and show you how to stop teeth grinding with the right plan and tooth protection.
How to Stop Teeth Grinding Before Bed: A Simple Night Routine That Works
A lot of people grind because their body is still “on” when their head hits the pillow. If you want a plan that feels doable, focus on calming your system and taking pressure off your jaw.
Cut the triggers that keep clenching alive.
Start with the easy wins. Have your last coffee early, and keep alcohol out of the late evening. If you vape or smoke, try not to use nicotine close to bedtime. These habits can make sleep lighter, which often shows up as jaw tension and nighttime clenching.
Do a 5-minute jaw reset
Before you lie down, check your mouth. Let your lips rest together, then leave a small space between your teeth. Place your tongue gently on the roof of your mouth. Add a warm compress on both cheeks for a few minutes, then do two slow open and close movements. You are aiming for muscle release, not big stretching.
Use one wind-down cue every night.
Pick something short you will actually repeat, like ten slow breaths and a quick note of tomorrow’s top task. A consistent cue helps your brain shift gears, which makes how to stop teeth grinding feel more realistic, not random.
Night Guard for Teeth Grinding: Custom vs Store-Bought
A night guard will not “fix” stress, but it can stop grinding from damaging your teeth while you work on the root triggers. The right choice depends on how often you clench, how strong the force is, and whether you already have restorations.
What a night guard actually does
A night guard for teeth grinding creates a protective layer so enamel, fillings, and crowns are not taking the full force of clenching. It can also help reduce jaw soreness by keeping the bite more stable overnight.
Store-bought guards: when they are acceptable
A boil-and-bite guard can be a short-term option for mild symptoms, travel, or while you wait for a dental visit. The downside is fit. If it feels bulky, shifts during sleep, or leaves you biting unevenly, it can increase muscle tension and overload certain teeth.
Custom night guards: why dentists recommend them
A custom night guard is made from impressions or a digital scan, so it seats securely and spreads bite pressure more evenly. For frequent bruxism, cracked dental work, TMJ symptoms, or sensitive teeth, custom is often the safer choice. Pairing a guard with habit changes makes how to stop teeth grinding far more realistic long-term.
Remedies Beyond a Night Guard: How to Stop Teeth Grinding
A night guard is great protection, but it is not the whole plan for teeth grinding at night. If the real issue is a stressed nervous system, an unstable bite, or jaw overwork, you will get better results by stacking a few practical supports.
If your dentist sees that one side is hitting harder, a careful bite check can reduce uneven bite pressure and help stop repeated fractures in cracked dental work. If cold sensitivity has started, treating worn enamel, smoothing rough edges, and using proven desensitizing products can make eating and brushing feel normal again. For tight muscles, simple jaw and neck stretches, a warm compress, and daytime “teeth apart” reminders often lower muscle tension and improve TMJ comfort.
If you also snore loudly, wake up gasping, or feel tired most days, ask about sleep screening. In many cases, that is the missing piece in how to stop teeth grinding long-term.

FAQs About How to Stop Teeth Grinding
Will a night guard stop grinding, or just prevent damage?
Most of the time, it is mainly tooth protection. A night guard for teeth grinding reduces wear and helps shield fillings or crowns, while you address the triggers behind bruxism.
How long does a custom night guard last?
It depends on how hard you clench. With good care, a custom night guard often lasts years, but heavy grinders may wear through one sooner. Bring it to checkups so the fit and bite are reassessed.
Why am I grinding if I do not feel stressed?
Stress is common, but not the only driver. Teeth grinding at night can also be related to sleep disruption, certain medications, or airway issues, which matters when planning how to stop teeth grinding long-term.
