What is Bruxism?
Bruxism is the technical term for grinding and clenching that abrades teeth and may cause facial pain. People who grind and clench, called bruxers, unintentionally bite down too hard at inappropriate times, such as in their sleep. In addition to grinding teeth, bruxers also may bite their fingernails, pencils and chew the inside of their cheek. People usually aren’t diagnosed with bruxism until it is too late because so many people don’t realize they have the habit. Others mistakenly believe that their teeth must touch at all times. About one in three people suffer from bruxism, which can easily be treated by a dentist.
What are the signs?
When a person has bruxism, the tips of the teeth look flat. Teeth are worn down so much that the enamel is rubbed off, exposing the inside of the tooth, which is called dentin. When exposed, dentin may become sensitive. Bruxers may experience pain in their temporomandibular joint (TMJ)-the jaw-which may manifest itself as popping and clicking. Women have a higher prevalence of bruxism possibly because they are more likely to experience tissue alterations in the jaw resulting from clenching and grinding. Tongue indentations are another sign of clenching.
Stress and certain personality types are at the root of bruxism. For as long as humankind has existed, bruxism has affected people with nervous tension. Anger, pain and frustration can trigger bruxing. People who are aggressive, competitive and hurried also may be at a greater risk for bruxism.
Can bruxism cause any harm?
Mild bruxism may not require treatment. However, in some people, bruxism can be frequent and severe enough to lead to jaw disorders, headaches, damaged teeth and other problems.
Because you may have sleep bruxism and be unaware of it until complications develop, it's important to know the signs and symptoms of bruxism and to seek regular dental care.
People who have otherwise healthy teeth and gums can clench so often and so hard that over time their teeth become sensitive. They experience jaw pain, tense muscles and headaches along with excessive wear on their teeth. Forceful biting when not eating may cause the jaw to move out of proper balance.
What can be done about it?
During regular dental visits, the dentist automatically checks for physical signs of bruxism. If the dentist or patient notices signs of bruxism, the condition may be observed over several visits to be sure of the problem before recommending and starting therapy.
There are several methods to help prevent any further damage to your teeth, such as custom-made night-guard appliances, TMJ toxins, rising the bite, composite or porcelain Veneers.

The objective of therapy is to get the bruxer to change behavior by learning how to rest the tongue, teeth and lips properly. When some people become aware of their problem, simply advising them to rest their tongue upward with teeth apart and lips shut may be enough to change their behavior and relieve discomfort.
