SleepTight Mouthpiece Full Review

The SleepTight Mouthpiece was created by Dr. Mike Williams, a member of the American Academy of Sleep Medicine. This dentist had a longstanding problem with snoring, so much so that he vowed to find a remedy for it. Dr. Williams and his team gathered information, feedback, and input on the already available anti-snoring devices and used this info to create the SleepTight Mouthpiece.

The SleepTight is a combination anti-snoring mouthpiece that realigns the jaw and advances the tongue forward to minimize snoring. The jaw advancement is set at 5mm, but you can increase if needed after the first few nights. 

The mouthpiece is durably made using latex-free and BPA-free material.

About SleepTight Mouthpiece; what it is and how it works

Sometimes, the tongue and soft palate tend to relax too much during sleep, blocking the airway and causing snoring. One effective way to stop snoring or at least minimize it is by using anti-snoring devices. This Mandibular Advancement Device -Tongue Retaining Device (TRD) combo is designed to reduce or end snoring completely. Like other MADs, the SleepTight Mouthpiece stops your snoring by advancing your lower jaw slightly forward and also pulls the tongue forward to keep the back of your throat clear and your air passage open. 

The SleepTight Mouthpiece is easy to use and can be customized at home using the boil-and-bite process. This mouthpiece is comfortable to use even if you suffer from congestion. It has a tiny hole that measures 6 millimeters that allows you to breathe through your mouth, unlike lots of other mouthpieces that do not allow you to breathe through your mouth.

Unlike most customized anti-snoring mouthpieces, which require that you pay the total price beforehand, the SleepTight Company allows you a 30-night trial period for testing out the SleepTight mouthpiece. You will be required to pay a small testing fee, but you only pay the total price if you are 100% satisfied with the product after the 30-night trial period. 

Materials and Options

The SleepTight Mouthpiece is made from FDA-approved thermoplastic that is both BPA and latex-free. It has a sturdy exterior that makes it durable and a soft inner core of material that creates a mold of your jaw.

The SleepTight anti-snoring device has a tiny airway in the center that fits in front of the gap in the teeth and a special fitting handle you insert into the airway. The fitting handle helps with the boil and bite impression and positioning the device before sleep.

It can be refitted up to five times, and it has a longer than average lifespan of six months to two years. 

You can wear your SleepTight Mouthpiece with partial dentures.
