While Invisalign trays look very similar to night guards and mouthguards, we do not recommend that you use Invisalign as a nightguard. The clear plastic trays are designed to gently shift your teeth, not protect them. If you grind your teeth at night, we may recommend that you get a night guard to protect your teeth and go with traditional braces instead of Invisalign. If you wear your aligners at night and notice that they are becoming cracked or worn down, this may be a sign that you are grinding your teeth at night. This will affect your treatment so be sure to let your doctor know right away if you think you might be grinding your teeth. If this is an extremely serious dental emergency, avoid spending too much time alleviating pain and discomfort. To save your tooth, your dentist must replace and splint it within 1-2 hours. Call us right away for immediate guidance, then come into our office to get the help that can’t wait.
