Sports (athletic) mouthguards are plastic dental appliances that, when worn, can provide a degree of protection for both the mouth's soft tissues (lips, cheeks, gums, tongue) and hard tissues (teeth and jaw bones). While all guards are made of plastic, their specific design, composition and method of fabrication vary. Custom mouthguards from Dr. DiBauda are sports mouth protectors that are individually made for an athlete. A well-designed custom mouthguard is typically considered to be able to provide the greatest level of protection for an athlete as compared to either a stock or boil and bite guard. The design of a custom guard can be individualized not only for the athlete but in some cases also for the specific sport that will be played when it is being worn.
