Bruxism, commonly known as "tooth grinding," is the process of clenching together and the grinding of the upper and lower teeth. During sleep, the biting force of clenched jaws can be up to six times greater than during waking hours.

Bruxism can cause complications over the years. It can wear down tooth enamel and break fillings or other dental work. Bruxism can worsen TMJ dysfunction, cause Jaw pain, toothaches, headaches, or earaches. It can also cause tooth sensitivity, tooth mobility, chipped teeth and erodes gums and supporting bones contributing to gum disease.

There is no cure for bruxism; however, the condition can be managed. The most common procedure to help to alleviate pain and discomfort is a Nightguard.
