Do you wake up refreshed, alert, ready to take on the day or are you tired with headaches or jaw pain? Bruxism and TMJ disorder, both often caused by teeth grinding or clenching during sleep, can cause many of these problems and disrupt your sleep. The CustMbite Nightguard was designed and developed by a team of dentists and engineers to help address these life-changing issues. You need a premium, professional product to solve this problem and that’s why CustMbite is dedicated to providing you with a comfortable, easy-to-use night guard that you'll actually want to wear. You may or may not suffer from jaw pain caused by TMJ or bruxing, but have you recently paid for a crown (or multiple) from your dentist? CustMbite night guards are Made in America.
