Teeth grinding, or bruxism, can cause a variety of problems, such as headaches, jaw pain, muscle tightness, and broken teeth. A mouth guard is designed to prevent this issue, and there are several types to choose from.

There are two types of bruxism:

  • Diurnal bruxism: This involves a person grinding their teeth while awake.
  • Nocturnal bruxism: This is involves teeth grinding during sleep.

A mouth guard is a device that a person wears to prevent teeth grinding, often during sleep. Below, we explore the various types of these products and describe when to see a dentist.

Please note, however, that the statements below are based only on research. No one at Medical News Today, including the writer, has tried these products.

While a person may not realize that they are grinding their teeth, bruxism can cause:

  • increased wear of the teeth
  • tooth fractures
  • limited ability to open the mouth
  • stiffness and tenderness in the jaw muscles
  • pain in the jaw joint
  • headaches
  • tenderness of the temporal muscles, located on the sides of the head near the temples
  • an earache
  • poor sleep

The American Dental Association explain that there are the following types of mouth guard:

  • Custom-made: These are made by a dentist and are typically the most comfortable.
  • Boil-and-bite: These are often available at sporting goods stores and drugstores. A person softens the guard in boiling water, then bites down, molding the material to the shape of their mouth.
  • Stock: This type of mouth guard is premade and ready to wear, but they may not fit as well.

A person might consider some of the following options of each type:

Chomper Labs offers custom-made mouth guards. First, a person selects the type of material:

  • Retainer: This is designed to prevent hard grinding and promote teeth retention.

A person may visit their dentist with symptoms of teeth grinding, such as jaw pain. Or, a dentist may notice the signs, such as broken teeth, at a regular checkup.

Anyone who has tried a mouth guard and still has pain or any other bruxism symptoms should return to the dentist. It is also important to do so if the guard causes discomfort or other problems.

A dentist may recommend one or more of the following ways to prevent teeth grinding, whether it happens during the day or night

  • Restorative treatment: This involves addressing damage to teeth.
  • Physical therapy: This may help with muscle pain or stiffness.
  • Psychotherapy: This may be useful if the cause is related to stress.
  • Medication: Antianxiety medication, tranquilizers, or muscle relaxants may help, depending on the cause of the bruxism.

Teeth grinding can lead to pain and other complications, and a mouth guard can help protect against it.

If a mouth guard does not work, a dentist can recommend further approaches to treatment.
