Bruxism (Teeth Grinding)
General Dentistry
What is it
Bruxism (BRUK-siz-um) is a condition in which you grind, gnash or clench your teeth. If you have bruxism, you may unconsciously clench your teeth when you’re awake (awake bruxism) or clench or grind them during sleep (sleep bruxism).
Sleep bruxism is considered a sleep-related movement disorder. People who clench or grind their teeth (brux) during sleep are more likely to have other sleep disorders, such as snoring and pauses in breathing (sleep apnea).
Mild bruxism may not require treatment. However, in some people, bruxism can be frequent and severe enough to lead to jaw disorders, headaches, damaged teeth and other problems.
Because you may have sleep bruxism and be unaware of it until complications develop, it’s important to know the signs and symptoms of bruxism and to seek regular dental care.
Signs and symptoms
- Teeth grinding or clenching, which may be loud enough to wake up your sleep partner
- Teeth that are flattened, fractured, chipped or loose
- Worn tooth enamel, exposing deeper layers of your tooth
- Increased tooth pain or sensitivity
- Tired or tight jaw muscles, or a locked jaw that won’t open or close completely
- Jaw, neck or face pain or soreness
- Pain that feels like an earache, though it’s actually not a problem with your ear
- Dull headache starting in the temples
- Damage from chewing on the inside of your cheek
- Sleep disruption
Dental approaches
If you or your child has bruxism, your doctor may suggest ways to preserve or improve your teeth. Although these methods may prevent or correct the wear to your teeth, they may not stop the bruxism.
- Splints and mouth guards. These are designed to keep teeth separated to avoid the damage caused by clenching and grinding. They can be constructed of hard acrylic or soft materials and fit over your upper or lower teeth.
- Dental correction. In severe cases — when tooth wear has led to sensitivity or the inability to chew properly — your dentist may need to reshape the chewing surfaces of your teeth or use crowns to repair the damage.
