Many people grind their teeth, whether they are aware they are doing it or not. This can cause a number of problems, including jaw pain, headaches and tense muscles. Teeth grinding can also hurt your teeth by wearing down the surface and enamel, leaving you vulnerable to cavities and other irritations. Night Guards are molded to fit either your upper or lower teeth, and are customized to fit perfectly, making them comfortable to wear. They’re soft and light so you will barely notice they’re there!
