Smilematters. Patient fact sheet. Be a good sport about mouthguards.
It is important to wear a mouthguard that is fitted properly to help prevent injuries to your teeth, lips, cheeks, tongue and jaw. Talk to your dentist about which one of the three kinds of mouthguards is right for you: ready-made, boil and bite, or custom-fitted. Be sure to wear you mouthguard during practice as well as during games.
