Your dentist may have recommended a night guard based on their exam and a discussion with you about possible bruxism which is clenching or grinding of the teeth, or possible TMJ disorder concerns. Either way, a night guard will help to prevent grinding, tooth damage and associated pain, and position the jaw to facilitate proper breathing, which may even relieve symptoms such as persistent snoring. Night guards are a great investment to protect your smile, prevent damage and the need for future dental treatment.
