What Is an Occlusal Guard and How Does It Work?

If you are prone to involuntary movements at night like grinding, biting, or clenching, your dentist or orthodontist may prescribe an occlusal guard. Also known as a nightguard, an occlusal guard protects your teeth from involuntary jaw movements by shielding the teeth from direct contact.

Occlusal guards do not prevent grinding and clenching, but they do protect the teeth from grinding up against one another. This can prevent issues like tooth damage, jaw pain, headaches, and countless others.
