Teeth grinding and clenching (Bruxism) is very common and can be painful and destructive to teeth and joints. Over the course of years, grinding or clenching can wear down the teeth. The exact cause is unknown, but it’s believed that stress and anxiety play the biggest role. Other causes may also be sleep apnea, snoring, an abnormal bite, and crooked teeth.
A night guard is a removable, custom-fitted plastic appliance that fits between the upper and lower teeth to prevent them from clenching/grinding against each other.
When you clench your jaw, the night guard lightens the tension and cushions the muscles in the jaw. This cushioning not only helps to prevent face and jaw pain but also protects teeth enamel. This appliance is intended to relieve temporomandibular joint pain. Mouthguards are usually worn at night to prevent grinding during sleep.
