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.

SomnoGuard 3
After years of intermittent sleep disturbance for my wife, the last 3 months were a real strain, with separate bedrooms a likelihood until I tried the SomnoGuard 3. Molding it to my bite was pretty easy. It was quite uncomfortable for the first night, with a lot of jaw pain, but thereafter I have found it is very comfortable. I fall straight to sleep as I always did, but I can only keep it in for about an hour, then wake up, take it out and go back off to sleep. Usually I don’t wake my wife again, but have had to pop it in for an hour again on one or two occasions. I have no jaw symptoms at all during the day. Highly recommended. daniel
Review Title
I was advised by my GP to see a sleep specialist and was diagnosed with mild sleep apnea he advised a SomnoGuard 3, I bought one, and if you have investigated these, you will see they are not cheap. When it arrived, the instructions that spread over 4 pages of A5 were quite difficult to understand, one time saying how easy the fitting process was the next moment suggesting quite the opposite. It was suggested in bold type at the start that inexperienced users should ask their dentist or physician to fit the device. I made an appointment with my dentist but she was not keen to take this task on, suggesting that it was quite simple and that I should be able to do it myself. So I left for a few days continuing to read and reread the fitting instructions. I waited until I could devote time to this, when I was alert and would be getting no interruptions. There is a small wooden spatula that is inserted in the device, projecting a few millimetres the other side for holding the device when hot. Timing is quite critical and with a timer I was aiming for 15 seconds max in the hot water, (just off the boil). At almost 15 seconds, the device just fell off the spatula into the hot water. Panic! By the time I had fished it out out of the water, it was completely ruined. And unusable. So a lot of money down the drain, and very disappointed! I don’t know if I can afford another attempt.

It works – couldn’t believe it – my boyfriend doesn’t have to disappear into the spare room because of my snoring. I filled in the online questionnaire and the SomnoGuard was advised. Fitting was fairly straightforward as instructions are really clear. Totally recommend this product. A life/relationship saver!!
Dribbles, aches
I did the snore test which recommended this product. My girlfriend now wears ear plugs instead so you’ll probably see where this review is going… It is very hard to get used to having your lower and upper jaw joined together while you sleep. I slept for maybe an hour in total the first night I wore this product. When I did sleep I only woke with drool on my pillow or almost choking on my own saliva that builds up with this product. The only redeeming feature is that my girlfriend said the snoring was less noisy but she still needed earplugs so it didn’t really work for me. I did try again, and again but considering the aching jaw every morning and the drool (I’m not sleeping on a towel as some people recommend like some kind of man-baby) and the fact that it only partially helped my snoring its not getting a great review or rating.
It worked, but the guard had other issues for me.
I took the questionnaire on the website, and bought the guard. I found the fitting instructions very comprehensive and clear. I managed to mould the guard successfully. My wife said that the guard stopped my snoring by around 90%. So, it definitely worked for me. I found the device a little weird at first, but I quickly adapted to sleeping with the guard in my mouth. Unfortunately after a few weeks, one of my canine teeth started to loosen. I stopped using the guard and within a few days the tooth recovered. The guard was not as tight as when I first used it, and maybe the slack fit put extra pressure on my tooth. I am 63 years old, and maybe this was a contributary factor. So, a great product, worked well, but I could not use it.
