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
This is an excellent product and my wife tells me that it works very well. I did the snore tests on your website and concluded that the somnoguard 3 would be best for me.I only had one problem and that was with the initial moulding to my mouth. The instructions said (I think) move the somnoguard about on the end of the ‘lolly stick’ in the hot water. I did this but the somnoguard fell off the stick (because of softening of the material) and was difficult to get out of the hot water without serious distortion. As a result the fit is not perfect but as I have said it works very well and I will probably order another one to get a better fit.
Effective Product
I bought the Somnoguard to try and prevent snoring. My husband states that anytime that I wear it I don’t snore so very pleased. I do find that I have hyper salvation and a small amount of mouth discomfort when wearing it. I would say these side effects outway the misery that snoring causes.I did the snore test and despite not concluding that I fitted the group which recommended the Somnoguard, I decided it was worth trying. I would definately recommend this product.
great time for sleep
Just after I moulded them to my gums we tried them out and had the best nights sleep in ages. To be recommended.
At last
It’s no exaggeration to say that the Somnaguard 3 probably saved my relationship. After moving in together my partner’s sleep suffered due to my snoring. I’ve snored for years – and have woken with headaches for many years – went to my GP in desperation – saw a consultant who explained that my lower jaw is smaller than my top jaw, hence a reduced airway. Back to GP who told me her husband had the same and uses a guard to bring his lower jaw forward – no snoring. Bought one, tried it and it’s the best purchase I’ve ever made – no snoring and much better sleep quality. Yes it looks a bit odd but we’re both so much more rested that it’s now a bit of a joke between us. Thanks
About 90% effective and made a real difference to us.
My husband and I have been sleeping in separate rooms for the past year or so because i just couldn’t get a good night’s sleep because of his snoring. I either couldn’t drop off to sleep and/or he would wake me in the middle of the night and it was getting debilitating.We had tried nasal strips and the mouldable nasal tubes – neither were effective. We decided to give this a go and my husband has been using it for about 6 weeks or so now.It is about 90% effective and we are now back to sharing the same room and bed which has been wonderful. He can still snore with it occassionally but even then it is quieter and less obtrusive than before and mostly he can only manage to breathe loudly!As with other reviewers it is uncomfortable to wear, especially in the first week or so and he complained of aching and sensitive teeth the next morning which does wear off pretty quickly. This is outweighed by being able to share the same bed again and he is now complaining less often.It was pretty easy to mould but we took heed of other reviews and were careful how much we heated it.
