Sports Dentistry is the treatment and prevention of oral/facial athletic injuries and related oral diseases and manifestations. In some sports, injury prevention, through properly fitted mouthguards are considered essential. These are the contact sports of football, boxing, martial arts and hockey. Other sports, traditionally classified as non contact sports, basketball, baseball, bicycle riding, roller blading, soccer, wrestling, racquetball, surfing and skateboarding also require properly fitted mouthguards, as dental injuries unfortunately, are a negative aspect of participation in these sports. Mouthguard design and fabrication is extremely important. First of all, it is essential to know that stock and boil and bite mouthguards bought at sporting good stores do not provide the optimum treatment expected by the athlete. There are four types of mouthguards presently available. The custom made mouthguards are designed by your dentist and are the most satisfactory of all types of mouth protectors. They fulfill all the criteria for adaptation, retention, comfort, and stability of material. They interfere the least with speaking and studies have shown that the custom made mouthguard has virtually no effect on breathing. There are two categories of custom mouthguards, the Vacuum Mouthguard and the Pressure Laminated Mouthguard.
