Bruxism / Tooth Grinding

Bruxism is the medical term for grinding, gnashing or clenching your teeth. The condition affects both children and adults.

Some people with bruxism unconsciously clench their teeth together during the day, often when they feel anxious or tense. This is different from tooth grinding or clenching that occurs at night, which is called sleep bruxism. Most children who are bruxers do so at night, while adults are either daytime or nighttime bruxers.

Bruxism may be mild and may not even require treatment. However, it can be frequent and severe enough to lead to jaw disorders, headaches, damaged teeth and other problems. Unfortunately, people with sleep bruxism usually aren't aware of the habit, so they aren't diagnosed with the condition until complications occur. That's why it's important to know the signs and symptoms of bruxism and to seek regular dental care

Signs and symptoms

The signs and symptoms of bruxism may include:

  • Teeth grinding or clenching, which may be loud enough to wake your sleep partner
  • Teeth that are worn down, flattened or chipped
  • Worn tooth enamel, exposing the inside of your tooth
  • Increased tooth sensitivity
  • Jaw pain or tightness in your jaw muscles
  • Earache — because of severe jaw muscle contractions, not a problem with your ear
  • Headache
  • Chronic facial pain
  • Chewed tissue on the inside of your cheek

Treatment

In many cases, no treatment is necessary. Many kids outgrow bruxism without special treatment, and many adults don't brux badly enough to require therapy. However, if the problem is severe, treatment options include:

Dental approaches. If you or your child has bruxism, your doctor may suggest a mouth guard or protective dental appliance (splint) to prevent damage to the teeth. Your dentist can make a custom mouth guard to fit your mouth. Over-the-counter mouth guards are available and they're less expensive than custom guards, but they generally don't fit well and can dislodge during bruxing.

If your bruxism seems to be associated with dental problems, your dentist may also correct misaligned teeth. In severe cases — when tooth wear has led to sensitivity or the inability to chew properly — your dentist may need to use overlays or crowns to entirely reshape the chewing surfaces of your teeth. Reconstructive treatment can be quite extensive and though it will correct the wear, it may not stop the bruxism.
