Key Takeaways

  • The Somnofit-S is a customizable mandibular advancement device designed to reduce snoring by advancing the lower jaw, and the maker says over 80% of users report reduced or eliminated snoring. It reduced our tester’s snoring from the first night.

  • Targeted mainly for individuals with obstructive snoring or mild sleep apnea, the Somnofit-S is not suited for everyone, especially those with certain dental issues, and may cause lower teeth to shift with prolonged use.

  • While the Somnofit-S offers a customized fit and was comfortable in our test, it may have limitations for mouth breathers and may not be effective if the mouth opens during sleep.

The Somnofit-S is a thermoformable mandibular advancement device (MAD), designed with the promise to reduce snoring and improve your breathing. It achieves this by advancing the position of the lower jaw to increase airflow. Sounds sophisticated, right? But how does it work in practice?

This anti-snoring device comes as a customizable mouth guard, complete with a unique temperature tool for a custom fit. By softening the upper and lower dental trays in hot water, they can be thermoformed to your teeth, ensuring a fit like a glove. A patented concept that sounds promising, so we put it to the test ourselves.

The manufacturer boldly claims that over 80% of its users have seen their snoring reduced or even completely eliminated. This is achieved by gently pushing the lower jaw forward to open the airways, thus preventing the narrowing or blockage that causes snoring. The Somnofit-S offers a level of customization that caters to both mouth shape and snoring severity with its interchangeable bands and various adjustments in 1mm increments. That is the maker’s own figure; our test results are below.

Our Hands-On Test (Video Review)

We bought the Somnofit-S and tested it ourselves. The video below shows the kit, the full fitting process and the fitted device.

  • In the box: the mouthpiece with its adjustment straps, a storage case, a temperature indicator and fitting directions that explain how to fit it to your bite and how to use the different straps.
  • Design: separate upper and lower trays joined by one of the straps. The straps set the jaw position for your bite, whether that’s an overbite, an underbite or a normal bite.
  • Fitting: put the temperature indicator in the water as it heats; it changes from green to red when the water is at the right temperature, and then you take the pot off the heat. The upper tray goes in for 3 minutes; lift it out with a spoon, shake off the water, place it in your mouth with the included tooth-print plate under it, and bite down. Repeat for the lower tray, then remove the plate and bite into both trays together, centered on your teeth. Finally, cut the strap for your bite (most bites use strap 3 or 4) and attach it to both sides of the lower tray and then to the upper tray. We used strap 3.
  • Results: our tester noticed less snoring from the first night. It fitted comfortably, and after the first night it became even more comfortable as they got used to it.
  • Build: made in Switzerland and well made. The fitting case is durable enough for travel.
  • Care: brush your teeth before fitting and wearing it, clean it every morning, and keep it in the case when not in use.
  • Verdict from our test: a high-quality anti-snoring mouthpiece that reduced snoring.

One tester’s nights are a real-world example, not a clinical trial. Snoring varies from person to person and night to night, and a snoring app or fingertip oxygen recording is not a sleep test.

Who Can Benefit from Somnofit-S?

So, who stands to benefit from this innovative device? Well, the Somnofit-S primarily targets individuals suffering from obstructive snoring or mild sleep apnea. The device aims to alleviate snoring and is also suitable for those with moderate sleep apnea. However, medical consultation is advised for sleep apnea patients, ensuring that it’s the right solution for your specific needs.

While the Somnofit-S seems like a one-size-fits-all solution, it may not be appropriate for everyone. For instance, individuals with certain dental or jaw issues, or those under 18 years of age, may not find it suitable. Prolonged use of devices like the Somnofit-S has been reported to cause the lower teeth to shift forward. It’s also worth noting that it is recommended for individuals with small to medium jaw sizes, with a typical lifespan of 8 to 15 months.

Moreover, the Somnofit-S is designed specifically to be effective for snoring due to narrowed airways in the throat and may not be as suitable for other types of snoring, such as those related to nose or vibrating tissue in the palate. It is recommended for users who haven’t found relief with positional therapy options. So, while it does offer a promising solution for many, it’s not a universal fix.

Setting Up Your Somnofit-S: A Step-by-Step Guide

Getting started with your new Somnofit-S is a straightforward process. The set includes:

  • The mouthpiece (upper and lower trays) with its adjustment straps
  • A temperature indicator that changes color when the water is hot enough
  • A tooth-print plate used while molding each tray
  • A storage and fitting case
  • Fitting directions

All you need is a pot of hot water to customize the device at home. In our kit, each tray went into the water for 3 minutes once the temperature indicator turned red.

A set of numbered straps of different lengths sets how far the lower jaw is held forward; the instructions say most bites use strap 3 or 4, and we used strap 3. This level of customization ensures that you’re getting the maximum comfort for peaceful nights.

After fitting, it’s advised to rinse the Somnofit-S thoroughly under running water for daily cleaning, ensuring the device is clean and safe for oral use. A simple rinse and you’re all set for a snore-free sleep!

Evaluating the Craftsmanship of Somnofit-S

Evaluating the craftsmanship of the Somnofit-S, it’s clear that this device is not your average mouthguard. Made from high-quality Swiss biomedical polymers, the device ensures safety for users with its stable, medical-grade plastic free of plasticizers. This level of quality is not to be taken lightly; after all, this is a device that will be in your mouth for extended periods.

The Somnofit-S has the following features:

  • Slim and elegant design for improved comfort and aesthetic appeal

  • Designed for small to medium jaw sizes

  • Durable life expectancy ranging from 8 to 15 months

  • Custom-fitted dental tray for teeth protection and long-term use

  • Ventilated blue plastic storage box for hygiene

Navigating the Features: How User-Friendly is Somnofit-S?

The Somnofit-S is more than just a mouthpiece; it’s a tool designed with the user in mind. With two dental trays connected by a flexible band, it secures the lower jaw in a forward position, allowing for customizable comfort and effectiveness.

One of the key features of the Somnofit-S is that you choose how far the jaw is held forward by picking a strap, which you cut and attach to both trays. That gives a customized fit for your bite. No more guessing or “one-size-fits-all” solutions.

With the Somnofit-S, you have control over your comfort and the effectiveness of snoring reduction. Different straps suit different bites, including overbites and underbites.

This level of customization, along with Swiss-quality craftsmanship, makes the Somnofit-S a user-friendly solution that offers precise, personalized relief from snoring.

Real-World Testing: Does Somnofit-S Deliver on Its Promises?

somnofit-s-fitted-with-straps

In our own test, yes. Our tester noticed a reduction in snoring from the first night, found it comfortable to wear, and found it more comfortable still after the first night as they got used to it. We fitted it with strap 3, which the instructions say suits most bites along with strap 4.

That is one person’s experience, so we don’t treat it as proof it will work for you. We also don’t repeat the satisfaction percentages and star ratings that circulate for this product, because we couldn’t trace them to a source we could check. The maker’s claim that over 80% of users see their snoring reduced or eliminated is the maker’s own figure.

Encountering Hurdles: Addressing Potential Somnofit-S Issues

While the Somnofit-S has proven effective for many, it’s not without its potential hurdles. For instance, while the device does allow for mouth breathing, some users may experience restricted airflow due to its design. This could pose an issue for individuals who primarily breathe through their mouths during sleep.

Another potential issue is for users who tend to open their mouths while sleeping. In such cases, the Somnofit-S may disengage, rendering the device ineffective. It may not be suitable for individuals who need a device that remains engaged despite mouth opening during sleep, unlike hinged versions offered by other manufacturers.

There are also specific health conditions and dental work to consider. The Somnofit-S is not recommended for individuals with:

  • Severe overbites

  • Jaw pain

  • Loose teeth

  • Serious gum or temporomandibular joint dysfunction

  • Braces, dentures, and bridges

As always, it’s important to consider these potential issues and consult with a healthcare professional before deciding if the Somnofit-S is the right solution for you.

The Somnofit-S Conclusion: Worth the Investment?

somnofit-s-fitted

As we draw our review to a close, the burning question remains: Is the Somnofit-S worth the investment? It is one of the more expensive over-the-counter mouthpieces, but in our test it was well made, comfortable and reduced snoring from the first night.

Priced at $149.99, the Somnofit-S comes with all necessary accessories for fitting and use, including the somnofit snoring device. When compared to the cost of other anti-snoring solutions – not to mention the priceless value of a good night’s sleep – the Somnofit-S presents an attractive option for those suffering from snoring or mild sleep apnea.

It’s a high-end option, and in our hands-on test it delivered: less snoring from the first night and a comfortable fit.

Summary

In conclusion, the Somnofit-S presents an intriguing solution for those plagued by snoring or mild sleep apnea. With its unique temperature tool, customizable fit, and Swiss-quality craftsmanship, it stands out in a market filled with generic, one-size-fits-all solutions. Its straps let you set the jaw position for your bite.

It may not suit everyone, but we bought and tested it ourselves and it reduced our tester’s snoring from the first night, so it’s worth considering if you want a premium, well-made device. After all, a good night’s sleep is priceless.
