Mouth guards can be used to protect your teeth from sports injuries and minimize grinding at night. These custom mouth guards are specifically fitted to your mouth. They come in a variety of colors. While custom mouth guards, considered by many to be the most protective option, other mouth guards can be effective if they fit well, are worn properly and stay in place.
Like any other sports gear, a mouth guard will wear out, making it less effective. If your mouth guard has holes or tears, or if it becomes loose, it can irritate the teeth and oral tissues. Occasionally check the mouth guard's condition and replace it as necessary.
