The duration of the treatment for Bruxism depends on your stress levels, which depend on what’s happening in your life and your frame of mind. You may need to wear a bite guard to protect the teeth from damage. There are different types of bite guard which can be discussed with your practitioner. The mouth guard stops you from damaging your teeth, because the wear and pressure will be on the guard, and not your teeth. If your nightly tooth grinding continues you’ll need to replace your mouth guard every few years.
