A nightguard is a custom-made appliance which is highly recommended for people who have Bruxism. Bruxism is the dental term for teeth grinding and clenching. Grinding and clenching the teeth may cause wear of the enamel of the teeth,fractures of the teeth, recession of the gums, bone loss around the teeth and TMJ (jaw joint) disorder.
People who grind/clench their teeth usually have other symptoms such as headaches, ear, neck, facial or jaw pain. Grinding usually occurs during the night because it is a subconscious neuromuscular disorder. Clenching can occur during both the day and night.
The use of a nightguard prevents further breakdown of the tooth structure and it also helps relax the TMJ (jaw joint) muscle, muscles of the face, head and neck thus preventing excess strain and discomfort. The nightguard trains the joint to relax and relieves pressure.
