Because a large percentage of sports injuries involve the face, we recommend mouth-guards to all our patients who participate in athletics. According to the ADA, boxers and hockey players aren’t the only kind of athletes who should wear mouthguards. Cyclists, weightlifters, gymnasts, and other recreational athletes should wear mouthguards, as well. At Princeton Smiles Dentistry, we create custom mouth-guards that form to the contours of your mouth for optimal comfort and function.
