Mouth Guards

What is a mouth guard?

A mouth guard is a flexible, removable device that fits in the mouth to protect the teeth, jaws, lips, tongue, cheeks, and gums. It should be worn when participating in athletic or recreational activities that might result in injury. Some of the higher risk activities include football, baseball, basketball, softball, soccer, volleyball, wrestling, skateboarding, rollerblading, biking, and karate. It is estimated that every athlete in the United States has a 10 percent chance of sustaining an injury to the face or mouth during each season of play and has a 45 percent chance of an oral-facial injury during his/her playing career.

How does a mouth guard work?

A mouth guard works as a shock absorber to cushion the mouth from the effects of a blow to the head, face, or neck. A mouth guard protects teeth from fractures. It also holds the tongue, lips, and cheeks away from the teeth to avoid lacerations. Proper use of a mouth guard can lessen the possibility of concussion and temporomandibular joint (TMJ) dislocation.


What are your choices?

There are three types of mouth guards:

  • A stock mouth guard is an inexpensive option that offers minimal protection. The poor quality of fit may interfere with speech and breathing. The Academy of General Dentistry does not consider a stock mouth guard acceptable as a protective device.


  • A mouth-formed protector, also called a "boil-and-bite" mouth guard, should be fitted by a dentist. Although these are less expensive than custom mouth guards, they do not fit as well or last as long.


  • A custom-made mouth guard offers the best protection because it is made to fit your teeth. Although it is more expensive, it is more likely to be worn because of superior fit, comfort, and quality. This type of protector does not interfere with speech or breathing. Consult your dentist about the type of custom-made mouth protector that is right for you.

How do you care for your mouth guard?

  • Don't handle or wear anyone else's mouth guard
  • Rinse your mouth guard after each use in cool water; occasionally, clean it with cool, soapy water and rinse thoroughly.
  • Store your mouth guard in a sturdy, well-ventilated container.
  • Avoid leaving your mouth guard in direct sunlight or in a closed automobile.

A mouth guard should be part of everyone's protective
equipment to prevent oral-facial injuries!
