Sports guards, mouth guards and mouth protectors are different names for the same thing: a device worn over your teeth that protects them from blows to the face and head. Mouth guards are an important piece of athletic equipment for anyone participating in a sport that involves falls, body contact or flying equipment. This includes football, basketball, baseball, soccer, hockey, skateboarding, gymnastics, mountain biking — any activity that might result in an injury to the mouth.
A properly fitted mouthguard may be especially important for people who wear braces or have fixed bridge work. A blow to the face could damage the brackets or other fixed orthodontic appliances. A mouthguard also provides a barrier between the braces and your cheek or lips, which will help you avoid injuries to your gums and cheeks.
