About Lief
Lief is a very small nighttime mouth guard that helps take the pressure off the most important points in your mouth, allowing your facial muscles to rest instead of stress while you sleep.
You’re not alone
If you’re experiencing chronic head and neck pain, you’re not alone. It’s highly probable your pain is caused by clenching and grinding your teeth at night, otherwise known as bruxism. Everyone does this to an extent, but for many people, this condition causes chronic inflammation of the muscle groups of your head, face, and neck. It is also often the cause of TMJ, ear pain, scalp tenderness, and in some cases, vertigo.
