How is Clenching and Grinding Treated?
There is no cure for clenching and grinding, instead the condition is managed.
The first step is to have an examination by your dentist. During this exam, your dentist will check for tenderness in your jaw muscles,
as well as for any dental and gum tissue abnormalities and damage caused by this condition. Your dentist will also interview you in an attempt
to arrive at a cause for your problem.
Generally, as a first, and sometimes only step, the pain and discomfort from clenching and grinding is alleviated using a custom fitted nightguard.
Further management of bruxism varies depending upon its cause.
