Top Tier In Mouth Protection

Many athletes use the sentinel mouth guard because it provide the highest level of protection, retention, comfort and custom fit without hindering their speech or breathing and most of all, their performance. Many persons that suffer from bruxism (teeth grinding) use our night time sleep guards because they can easily sleep with our devices in. These dentist grade night time teeth protectors are comfortable, they stay in place, and the cost is very affordable. Our custom fit mouth guards perform much better then the typical boil and bite mouth guards, because of the superior fit and quality. In addition, Sentinel mouth guards are thin and comfortable, while still maintaining their custom shape and the protection long after the other mouth guards have worn out.
