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 saviour
I bought a Somnoguard as a kind of last hope that it would save my partner from my extremely load snoring, I honestly didn’t think it would help…..but how wrong could I be, it’s brilliant and works extremely well, it takes a little getting used to wearing but now I’m used to it I don’t have any problems and my partner can finally have a good night’s sleep
works but uncomfortable
I found that the somnoguard 3 works in the sense that the snoring is greatly reduced. The hole in the mouthpiece is breathable, but it feels very uncomfortable to me and sometimes makes me wanna throw up. I am used to wearing a mouthpiece in sports, so it is not that per se.
Good so far
Have been wearing the Tomed SomnoGuard 3 for four nights now. The first night I didn’t think that I would be able to get used to it when I first put it in, but I did manage to get a good night sleep. Each night I am getting more used to it, and feel that I am sleeping better. More importantly my wife is getting a decent night’s sleep as well.When I wake up in the morning my jaw feels out of position, but I am expecting that will go with time, as I get more accustomed to the device. It is still early days. So that is why I can’t give it a score of ten, but hopefully if I review it in a few weeks time that will change.
It does what it says on the 'tin'
This little device does work and it has stopped my snoring completely. However, it is quite difficult to get it to fit. The procedure to soften the plastic and mould it to your own mouth is quite involved and you don’t get many chances if you get it wrong. Because it is crucial to get the device into your mouth while it is still malleable I was a bit panicky (not wanting to waste £37). When the device had been softened it was less obvious which was the top so I ended up putting it in my mouth upside down. I suggest you write something on the wooden spatula, which is used to hold it, to identify the top and bottom.I used the device in the upside down moulding for a few nights and it did stop me snoring but I felt that it would probably fit better if it was the right way up. I had another go at moulding it but this time the right way up. It ended up a bit lopsided and I found it made my back teeth ache on one side so I have had to have another go at moulding it to try to get it in the middle of my mouth.I also found it extremely difficult to gauge if I was pushing my bottom jaw forward enough once the device was in my mouth and being moulded, and almost impossible to push my tongue against the bottom part of the device while sucking in and biting hard – all at the same time. I hope that I now have it correctly fitted and I also hope that it lasts a long time because I don’t fancy going through all that again!
Buy something else
This didn’t work for me. I have had a snoring problem for years and have tried numerous products in an attempt to find the best one for me.I did the questionnaire and this is what was recommended for me so I thought I’d give it a whirl. I followed the instructions to the letter and popped it in when I went to bed but it kept slipping off my top teeth which meant my mouth wasn’t in the position it should have been. So next day I tried re-moulding it but the fitting was even worse this time. So I tried again, and it was even worse than the second time.By the time I realised it wasn’t for me, my 30 day guarantee period had expired so I couldn’t return it. So money wasted.The moral of this story? Good luck with the fitting as you only get one go to get it right! I couldn’t manage it and, like I say, I followed the instructions perfectly (so I thought!)
