Description
The Tomed SomnoGuard® 3 is a one-piece mandibular advancement device designed to reduce snoring and help manage mild to moderate OSA. Worn during sleep, it gently holds the lower jaw and tongue forward to keep the airway open, improving airflow.
This boil-and-bite device is made from medically safe, hypoallergenic thermoplastic that softens in hot water and moulds to your bite for a secure, custom fit. For best results, we strongly recommend having the device fitted by a healthcare professional (such as a dentist, ENT specialist, or sleep physician), although it can be fitted at home.
The Tomed SomnoGuard® 3 fits most jaw sizes due to its flexible material. It’s generally well tolerated, though some users may experience mild, temporary side effects like excess saliva or slight morning discomfort. The instructions for use include all potential side effects.
The material contains no allergens, latex, silicone, BPA, or phthalates. The typical lifespan of the product is 6-12 months, though heavy jaw movement or teeth grinding (bruxism) may shorten this.
Please note: Unobstructed nasal breathing is required to use this product. Consult your dentist if you have concerns about your teeth or jaw alignment before using, or your doctor if you have concerns about your snoring or OSA.

Snoring and mild to moderate OSA often occur when the airway becomes narrowed or blocked during sleep. This can happen when the muscles in the throat relax, causing the tongue and soft tissues to fall back and restrict airflow.
The Tomed SomnoGuard® 3 is designed to gently hold the lower jaw and tongue in a slightly forward position. This helps open the upper airway and stabilise the soft tissues in the throat, including the soft palate and uvula, which are responsible for the vibrations that cause snoring.
By improving airflow and reducing obstructions, the Tomed SomnoGuard® 3 can help reduce snoring by limiting tissue vibrations and support more regular nighttime breathing in cases of mild to moderate OSA.
Please note: Due to hygiene reasons, fitted or used devices cannot be returned, so refunds aren’t possible if fitted incorrectly.
For best results, we strongly recommend having the device fitted by a healthcare professional (such as a dentist, ENT specialist, or sleep physician).
However, we understand some users may choose to fit the device themselves. If you do, please refer to the detailed instructions provided for a step-by-step guide on how to mould the device. You can also watch the fitting video for additional guidance.
The Tomed SomnoGuard® 3 uses the boil-and-bite method, where the thermoplastic material softens in hot water and hardens to fit your teeth and jaw position once cooled.
The fitting process takes about 15 minutes and involves the following steps:
- Heat the device in hot water for 20 seconds.
- Bite into the softened material with your lower jaw slightly forward.
- Cool the device in cold water to harden it and set the shape.
What is a mandibular advancement device?
A mandibular advancement device is a type of mouthpiece worn while you sleep. It works by gently moving your lower jaw forward, helping to keep your airway open. This can reduce snoring and is often recommended to support symptoms of mild to moderate OSA.
You may have also heard mandibular advancement devices (often abbreviated to MADs) called a mandibular advancement splint, mandibular repositioning device, or even a mandibular device for snoring – but these are all just different names for the same type of oral device.
What’s the difference between a mandibular advancement device and a mouth guard?
Although they can look similar, a mandibular advancement device is specifically designed to reposition the jaw and improve airflow. A regular mouth guard, used for sports or teeth grinding, doesn’t move the jaw forward and won’t usually help with snoring.
People often search for terms like mandibular mouth guard, MAD mouth guard, or snoring mouth guard when what they’re actually looking for is a mandibular advancement device – the correct type of oral appliance for reducing snoring and easing the symptoms of mild to moderate OSA.
Do mandibular advancement devices really work?
Many people find that a mandibular advancement device helps to reduce snoring, though results can differ from person to person. Clinical studies indicate they can be effective. They’re also recognised within the NHS as a treatment option for snoring and for some cases of mild to moderate OSA.
Are mandibular advancement devices comfortable?
Like any oral appliance, a mandibular advancement device can take a little time to get used to. Adjustable or custom-fit designs usually provide the best comfort for long-term use.

Unable to mould effectively
I found the device difficult to mould effectively. I timed the seconds carefully in the water but when I lifted the device out it was too soft to mould effectively. I tried it again but it was too misshapen. I would recommend people only immerse the device in water for 15 seconds, rather than 15-20 seconds. Sadly for me, it has been £40 wasted.
Disappointing
Hoped that this would be more effective than the snorewizard, however, it is sadly not. The device is difficult to fit effectively due to the need to press your tongue against plastic that has been dipped in boiling water… perhaps I am the wrong type of snorer and the device is not to blame, however the fact that you can’t return it after opening (for obvious reasons admittedly) means that you are taking a risk spending the money and hoping for a cure. On the plus side this is more comfortable than the snorewizard… but as it doesn’t work this is fairly irrelevant.
What a difference!
Yes it takes a couple of nights to get use to the device but its worth it. I am sleeping right throughout the night as is my partner and no need for separate bedrooms. so THANK YOU
massive disappointment
Having used Mandibular Advancement Devices with great success for about three years I was intrigued to try this advanced” version. Unfortunately it turned out to be a massive disappointment. Although the concept of it moulding to your mouth seems a good one in reality as soon as I put the guard into the hot water it shrunk considerably and as a result although it was tailored to my mouth it was far too small and therefore wouldn’t stay in place.”””
It's actually working...
I’ve always snored, I believe it runs in the family. In the last 6 months or so, it has got so bad that my partner isn’t sleeping well, I’m not sleeping well and even my neighbours got disturbed. I was willing to try anything to improve the situation and came across this product via a snore test. The instructions were clear, so I was able to mould the guard to fit my mouth easily. The first week or so was uncomfortable as I’m not used to sleeping with a mouth guard, but I persevered. Now I’m used to sleeping with it, it really does seem to do the trick! My partner has been sleeping much better and I don’t have the horrible sore throat feeling after a night of snoring. The feeling in the jaw once you remove the mouth guard is unpleasant, but a reasonable price to pay for a decent night�s sleep.
