When a person has bruxism the tips of their teeth look flat. If teeth are worn down so much that the enamel is rubbed off, the inside of the tooth (dentin) will be exposed causing the tooth to become sensitive. Bruxers may experience also pain in their temporomandibular joint (jaw or TMJ), which manifest as popping and clicking of the jaw.
However, your dentist can make a custom plastic mouth appliance, such as a night guard, that’s worn over night to absorb the force of biting and the grinding. This appliance can prevent future damage to your teeth and is helps change the destructive behavior.
A mouthguard/sportsguard is a flexible appliance that is worn in athletic and recreational activities to protect teeth from trauma. The dental profession unanimously supports the use of mouthguards in a variety of sports activities because it can prevent serious injuries such as broken teeth, jaw fractures, cerebral hemorrhage and neck injuries. They are also effective in moving soft tissue in the oral cavity away from the teeth, preventing laceration and bruising of the lips and cheeks.
