Installation and Adjustment

01

Choose your starting strap based on your bite. If you have an overbite, start with strap number 1 or 2. If you have a common bite, start with 3 or 4. If you have an underbite, start with strap 5. 

02

Use a pair of scissors to remove the starting strap (as recommended above). Keep the other straps for now. 

03

Insert the hook of the upper molding into the central hole on the strap and turn it 45 degrees.

04

Ensure the writing on the tensioning strap is visible on the outside. 

05

Proceed in the same manner with the side hooks of the lower molding, thus locking the strap.

Frequently Asked Questions

Choose your strap based on your dental alignment (underbite, normal bite, or overbite) and desired advancement level. Start with the lowest advancement and increase gradually.

If you have an overbite, start with strap number 1 or 2. If you have a common bite, start with 3 or 4. If you have an underbite, start with strap 5.

Currently, the maximum FDA-approved advancement setting is 6mm. We are in the process of obtaining clearance for an 8mm advancement.

We recommend using each advancement setting for three to five nights before moving to a higher setting to ensure comfort and effectiveness.

Typically, the straps can last over a year. However, factors such as teeth grinding can cause the straps to stretch out sooner.

While the straps can be replaced independently, we recommend replacing the entire device periodically for hygiene reasons and to counteract wear from the acidity in the mouth, which can degrade the mouthguard over time.

Your replacement straps come with a 30-Night Money-Back Guarantee starting at delivery. Contact us within 30 days of delivery to request a return, even if the straps have been opened, fitted or used. Help with strap selection and fit is optional. See our return policy.

Fantastic!

I'm sleeping better than ever before! Less snoring, more sleeping...thanks!

So happy to find this!

No more snoring! I’m so glad this works when nothing else did, including another company’s mouth guard. I moved up from the #3 band to the #4 to totally eliminate my snoring but even the looser band was an HUGE improvement, according to my partner. I can’t say I love using it but I do love not driving my partner out of the bedroom!

Replacement straps work great!

Glad there is an option for replacement straps! Just be careful not to pull them apart - you have to cut them apart - otherwise the connections can get stretched out too much.

Overall Somnifit experience!

I am extremely happy with the company and the product, the fit on the mouthpiece was tight and it is made from seemingly high quality materials, unfortunately the mouthpiece hurt my teeth (because I have stress most likely) and so I returned it to them, overall a great product, and I will try it again in the future!

Hi Rory,

Thank you so much for the detailed review — we really appreciate it. We're glad to hear you were happy with the product quality and fit, but we're sorry the mouthpiece caused discomfort for you. Stress can absolutely make teeth more sensitive, and it’s something we hear occasionally. If you ever decide to give Somnofit-S another try, we’re always here to help you find the most comfortable setup. Thanks again for giving us a shot!

Getting Better!

Somnofit S has reduced my snoring, especially if I can stay sleeping on my left side. Now adding Myofunctional Therapy exercises as a preventive measure.

Helps overall, less snoring, but not eliminated though

Snoring an hour or less most nights, which is better than 2+. Straps stretch too easy and there aren’t shorter.

Super responsive

Love my mouth guard and replacement strips. I no longer need my Bipap!

Thanks so much, Jeff — that’s incredible to hear!

We’re thrilled the Somnofit-S has been such a game-changer for you. Hearing that you've been able to move away from your BiPAP is no small thing, and we’re honored to have played a part in that. Also glad the replacement straps are working smoothly for you — let us know if you ever need more or have questions down the line.

Best Find

I’ve tried countless different mouth guards to help with my snoring -from cheap $20 gimmicks to professionally fabricated custom $4000 mouth guards, and even designed and made my own a few times. The somnofit snore guard is without a doubt the best and most effective and reliable mouthpiece I’ve tried yet. In fact, I’ve ended my search for anything better because I honestly don’t think it exists. One thing I would like to see in the future is an option to add a spacer near the molars for those who suffer from grinding or struggle to nose breath due to congestion and/or deviated septum, this way the mouth can remain open at night.

David, this is such an incredible review — thank you! 🙏
It means the world to hear that after trying everything (including building your own!), the Somnofit-S has earned a permanent place in your routine. That’s exactly what we aim for, and we're so glad it's delivering consistent results for you.

Also — we've noted your suggestion about a spacer for grinders or congested breathers. We’re actively gathering feedback for future improvements. Thank you for sharing it!

Here’s to continued restful, snore-free nights!
