SleepTight Mouthpiece is an anti-snoring device that you can use to prevent snoring while you are sleeping. It is a Mandibular Advancement Device or MAD that works by moving the lower jaw forward. The SleepTight Mouthpiece opens the airway, which eliminates the vibration which causes snoring.

The mouthpiece was designed by a US dentist, developer, and researcher of mouthpieces Dr. Mike Williams. Over 10 years ago he started looking for alternatives to surgery as a way to help snorers. He had been through multiple surgeries and sadly experienced no remedy.

He has over 30 years of experience in cosmetic dentistry, and prior to developing the SleepTight Mouthpiece, he spent five years working on mouth guards and mouthpieces. Dr. Williams specifically waited to have his product FDA approved before offering his product to the public.

The SleepTight Mouthpiece technical stuff

The SleepTight Mouthpiece is a typical MAD device that you must use the boil and bite method to get the custom fit done properly. MAD devices allow you to custom fit the piece to your jaw. A MAD device extends your lower jaw forward, which opens the airway preventing you from snoring. If you have a narrow airway, the tongue slips back into it while sleeping this will partially block the airway causing vibrations that lead to snoring.

The SleepTight Mouthpiece has a hard exterior and an inner core of material that gets softened to create a mold of your haw. So, it if it’s tight to stay in place, but its strong exterior makes it extra durable. This SleepTight Mouthpiece features an air hole that measures 6 mm, so it is not so large that it forces your mouth to remain in an uncomfortable position all night.
