DIY Bite Guard

Teeth grinding, also known as bruxism, can be a pain, literally 1. Teeth grinding can be caused by stress or misalignment of how the teeth fit together. Bruxism can lead to damaged or broken teeth, jaw disorders, osteoarthritis of the jaw, bone loss, periodontal disease, and headaches. Often dentists will prescribe a fitted mouth/bite guard to wear at night to protect the teeth. These bite guards can be very expensive if made by the dentist. Cheaper bite guards can be purchased from sporting good stores and easily molded to the teeth at home.

Purchase a sport mouth guard from a local sporting goods store, pharmacy or super center. These mouth guards come in different sizes, so make sure to buy the appropriate size for the mouth.

If proper fit is not obtained in first fitting it can be done again. If alterations need to be made, the mouth guard can be heated and cut to fit.
