If you grind or clench your teeth

Teeth grinding (bruxism) or clenching strains the TMJ and related muscles. If you have these habits during the day, doing self-checks can help you stop. But it’s hard to control these habits when you’re asleep. That’s when using a splint may help:

• How a splint works. A splint is an appliance that fits in the mouth. It may also be called an orthotic or night guard. There are different kinds of splints for different kinds of needs. A splint can keep the upper and lower teeth apart. This helps protect tooth surfaces from grinding. A splint can also be made to reduce strain on the area.

• Wearing and caring for your splint.  To make a splint, your dentist or orthodontist may take impressions of your teeth. Then a splint will be made to fit your mouth. A splint:

  • May be worn during the day or only at night. Ask when and how often you should wear your splint.

  • Should be cleaned before you put it in and after you take it out. Ask your dentist or orthodontist how to clean the splint.

  • Should be kept in a protective case, away from the reach of children and pets. This helps keep the splint from getting dirty or broken.

Seeing an oral and maxillofacial surgeon

Your dentist may refer you to an oral and maxillofacial surgeon if self-care, medicines, and other noninvasive treatments don't work. This surgeon will specialize in treating TMD. They may advise shots (injections) to treat the pain. Surgery is rarely needed for TMD. Talk with your provider to see if surgery might be right for you.
