What is a night guard and what does it do?



What is a night guard and what does it do?

TMD is the most devastating and most frustrating disorders for patients who come to dentists. Moreover, this disorder is the most difficult to treat conservatively. It affects mostly 3rd and 4th decades of life and usually women are more effected than men.
It has been shown and according to recent studies that bruxism and clenching have a role in causing
 TMD.

Bruxism is the grinding of teeth. Biting forces in bruxism are significantly stronger than regular chewing. These biting forces can wear down teeth and joints as well as create jaw muscle soreness.
Bruxism occurs in about one in every 10 people. Most dental patients are unaware of their bruxism, largely because it occurs at night while they are sleeping. It is usually the patient’s spouse who notices the bruxism because they can see and hear the grinding of teeth.

Signs of Bruxism include bulging size of the muscles of mastication, mobility of teeth, wear and fracture of teeth, fillings, crowns and dentures, as well as recession of gums.

Clenching is a bad habit that is difficult to control and occurs during the day. This habit involves the constant application of force by the lower and upper teeth. Clenching has many of the signs also found in bruxism.

What is a Nightguard?
A nightguard is a dental appliance, as shown below, made from a hard or soft acrylic that is typically worn at night while sleeping. When worn properly, nightguards can make a world of difference for bruxers and clenchers by reducing the wear on teeth, and preventing the fracture and failure of crowns, fillings and dental implants.

Many patients with TMD have a relief from the pain of TMD after wearing the nightguard. The length of time for wearing the nightguard depends on the severity and intensity of the pain.

If you have these habits, it is better to contact your dentist before you develop TMD.
