Teeth Grinding (Bruxism): Signs, Causes and Treatment

Oct 13, 2026
Teeth grinding (bruxism) can wear down and crack teeth. Learn the signs, causes, and treatment options, including nightguards, from BH Dental NY in Harlem and Brooklyn.

Teeth grinding, also called bruxism, is the habit of clenching or grinding your teeth, often during sleep and often without realizing it. Over time, teeth grinding can wear down enamel, crack teeth, cause jaw pain, and trigger headaches. The good news is that it is very treatable, and the earlier it is caught, the more of your teeth you can protect.

At BH Dental NY, Dr. Leslie Azran and the team help patients at our offices in Harlem and Brooklyn identify teeth grinding early and repair the damage it causes.

What Is Teeth Grinding (Bruxism)?

Bruxism is the involuntary clenching, gnashing, or grinding of the teeth. It can happen while you are awake (awake bruxism), often during moments of concentration or stress, or while you sleep (sleep bruxism). Many people only find out they grind their teeth when a partner hears it or when their dentist spots the wear.

Signs and Symptoms of Teeth Grinding

  • Flattened, chipped, or worn down teeth
  • Increased tooth sensitivity to hot, cold, or sweet foods
  • Jaw pain, tightness, or soreness, especially in the morning
  • Dull headaches, often starting at the temples
  • Clicking or popping in the jaw joint
  • Earache-like pain without an ear infection
  • Indentations on the sides of the tongue or damage inside the cheeks
  • Loose teeth or broken fillings and crowns
  • A partner hearing grinding noises at night

Causes of Teeth Grinding

Cause How It Contributes
Stress and anxiety Tension often shows up as clenching, both day and night
Sleep disorders Bruxism is linked to conditions such as sleep apnea
Bite or alignment problems Misaligned or missing teeth can affect how the jaw closes
Caffeine, alcohol, and tobacco These can increase the likelihood of grinding
Certain medications Some medications can have grinding as a side effect
Habit Some people clench out of habit while concentrating

Often, more than one factor is involved, and the exact cause is not always clear.

What Happens If Teeth Grinding Goes Untreated?

Grinding puts far more force on your teeth than normal chewing. Over time, it can lead to:

  • Worn enamel and increased sensitivity
  • Cracked or fractured teeth, which may need emergency dental care
  • Damaged crowns, fillings, and veneers
  • Loose teeth or tooth loss, which may call for a dental implant
  • Jaw joint disorders (TMJ) and chronic facial pain
  • Frequent headaches and disrupted sleep

How Is Teeth Grinding Diagnosed?

Your dentist can often spot bruxism during a routine exam by checking for worn or chipped teeth, tenderness in the jaw muscles, and changes in your bite. They will also ask about your sleep, stress levels, headaches, and habits, and may use X-rays to evaluate damage.

Teeth Grinding Treatment Options

  1. Custom nightguard. A nightguard fits over your teeth and cushions them while you sleep, protecting them from wear and cracks. A dentist-made guard fits better and lasts longer than store-bought versions.
  2. Stress management. Exercise, relaxation techniques, better sleep habits, and counseling can reduce stress-related grinding.
  3. Reducing caffeine, alcohol, and tobacco. Cutting back can lessen grinding episodes.
  4. Treating bite problems. Correcting alignment with options like Invisalign can help in some cases.
  5. Restoring damaged teeth. Crowns, bonding, or veneers can repair teeth worn or chipped by grinding. See all options on our services page.
  6. Addressing sleep disorders. If sleep apnea or another condition is involved, treating it may reduce grinding.
  7. Medical treatments. In some cases, other treatments may be recommended in coordination with your doctor.

Tips to Stop Grinding Your Teeth

  • Notice and relax your jaw during the day: lips together, teeth apart
  • Avoid chewing gum, pens, or ice
  • Limit caffeine and alcohol in the evening
  • Build a relaxing bedtime routine
  • Wear your nightguard consistently
  • Keep up with regular dental checkups

Teeth Grinding in Children

Many children grind their teeth, and most outgrow it. If your child grinds often, complains of jaw or ear pain, or you notice worn teeth, mention it at their next dental visit.

Frequently Asked Questions

What causes teeth grinding?

Common causes include stress, anxiety, sleep disorders, bite problems, caffeine, alcohol, tobacco, and certain medications. Often several factors combine.

How do I know if I grind my teeth at night?

Common clues are morning jaw soreness, headaches, worn or chipped teeth, and a partner hearing grinding. A dentist can confirm by examining your teeth and jaw.

Is teeth grinding harmful?

Yes, over time. It can wear down enamel, crack teeth, damage dental work, and cause jaw pain and headaches.

How do you stop grinding your teeth?

A custom nightguard protects your teeth, and reducing stress, caffeine, and alcohol can help. Treating bite or sleep issues may also reduce grinding.

Can teeth grinding cause headaches?

Yes. Clenching and grinding strain the jaw and facial muscles, which can cause tension headaches, often in the morning.

Do I need a nightguard if I grind my teeth?

If grinding is causing wear, sensitivity, or pain, a nightguard is often recommended to protect your teeth. Your dentist can advise based on your exam.

Can teeth grinding be cured?

Grinding is usually managed rather than cured, since the underlying causes vary. With a nightguard and lifestyle changes, damage can be prevented and symptoms reduced.

Can teeth damaged by grinding be repaired?

Yes. Depending on the damage, options include bonding, crowns, veneers, and in severe cases a full restorative plan.
