It's very common that sports injuries to the head result in chipped, broken or avulsed teeth and even fractured or broken bones including the jaws. The jaw joint or TMJ is also susceptible to sport injuries. In some cases, your muscles or ligaments in your face may be torn or injured from getting hit in the face – even if the bones aren’t broken.
Symptoms indicating a TMJ injury include jaw pain, stiffness, change in the bite, problems with chewing or talking, headaches, earaches, and more. One of the best ways to protect against these type of injuries is a properly fabricated athletic guard.
