Karate Mouth Guard

A mouth guard (or mouth protector, gumshield) is a flexible device worn over teeth to protect them from injury, acting like a helmet for your mouth, and is used in sports, for teeth grinding (bruxism), and to help with snoring or sleep apnea by repositioning the jaw. They are made of plastic or rubber, come in different types (stock, boil-and-bite, custom-fitted), and can prevent chipped teeth, jaw damage, and even reduce concussion impact by absorbing shock and keeping teeth apart.
