Nightguards are the most common treatment for Bruxism. Bruxism is an involuntary grinding of the teeth and clenching of the jaw muscles that occurs to some extent of most people. Bruxism often occurs during sleep and is one of the most common sleep disorders. Bruxism can range from mild wearing of the teeth and muscle tenderness to significant pain from dental and muscular issues. Dental issues that can arise from Bruxism include abnormal wear patterns on the chewing surface as well as abfractions on the gum line and fractures in the teeth. Over time severe wear can lead to tooth loss and significant gum recession. Since bruxism also includes clenching of the jaw muscles it can lead to facial muscle pain and headaches. Severe cases can lead to or be a result of Temporomandibular Joint Disorder or TMD..
