Mouth Guards and Dental Emergencies

The importance of mouth guards

A mouth guard is usually a flexible piece of plastic or rubber that fits into the mouth. It should be worn during all recreational and athletic activities to protect the mouth and teeth from serious injury. It should especially be worn during activities where there may be contact with another person, piece of equipment, or the ground. In particular, mouth guards should be worn during these sports:

  • Football

  • Basketball

  • Soccer

  • Rugby

  • Wrestling

  • Baseball

  • Softball

  • Lacrosse

  • Field hockey

  • Ice hockey

  • Martial arts

  • Boxing

Some of these sports need the use of a mouth guard at the amateur level.

Many recreational activities, such as skateboarding and bicycling, also pose a risk of injuring the mouth and teeth. Use caution during these activities.

Mouth guards and preventable injuries

Many injuries to the teeth, mouth, and head could be prevented with correct and regular use of a mouth guard. These injuries may include:

  • Dislodged or knocked-out teeth.

  • Broken or chipped teeth.

  • Bitten or cut (lacerated) tongue or lip.

  • Objects caught or lodged between the teeth.

  • Jaw fracture.

  • Jaw collision, when the lower jaw gets jammed into the upper jaw.

Types of mouth guards

There are several types of mouth guards. Three of the most common types are:

  • Premade mouth guards. One type is already made and can be found in most sports stores or pharmacies. There are different types and brands. Choose the one that fits best and is most comfortable.

  • Boil and bite. These are also known as self-adapted mouth guards and are available at sporting goods stores or pharmacies. These mouth guards are softened in hot water, then shaped to the mouth while still soft.

  • Custom-made mouth guards. Your dentist can make a mouth guard specifically for you. These may be more expensive but are usually more comfortable.

Ask your dentist or doctor about the best type of mouth guard to use.

Mouth guard care

Clean your mouth guard regularly with cool water and soap. Rinse it well. Also rinse it between uses. Store it in a container with vents so it can dry. Replace the mouth guard if it's damaged or worn.
