You can help to prevent jaw fractures by avoiding trauma to your chin and lower face. To do this, you should:
Always use seat belts and shoulder harnesses when you ride in a car, even if your car is equipped with airbags. Buckling up will help to protect your facial bones and upper body from dashboard impacts and other injuries.
Wear headgear and a mouth guard during contact sports. In addition to protecting your teeth from impacts, mouth guards offer some protection against jaw fractures. Both the thermoplastic "boil-and-bite" models and the custom-made forms are effective.
If you are a parent, do not allow your child to participate in amateur boxing. The American Academy of Pediatrics opposes the sport of boxing for young people.
