Bruxism is an unconscious and involuntary activity of the jaw, which causes tooth grinding and clenching. It is usually happens during sleep but it may also occur awake. It is often associated with anxiety, stress and if someone has occlusal irregularity, it might also trigger this gnashing motion. While clenching is a quiet habit when teeth are pressed together firmly, grinding can cause noises as well.

But this isn’t the only disadvantage of bruxism. The enamel of the teeth can wear out after a while which leaves the dental crown unprotected and can easily break or damage. In addition to this, it can also cause periodontal breakdown, and joint or neuromuscular problems, it might lead to some serious temporomandibular joint (TMJ) problems as well. A mouthguard can easily solve this but it is advisable to consult with an orthodontist beforehand.
