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.

IT WORKS (at least for me)
Very good item – after I adjusted as instructed I had no trouble to use it all night long. And my girlfriend is happy!! No more noises on my side of the bed 😉
Didn't work for me
I had tried the Snore Guard previously as being the cheapest device available to stop my snoring. This didn’t work perfectly as my lower jaw tended to drop whilst asleep and the noise started again. I reviewed the other devices available and opted for the Tomed SomnoGuard 3 as the next best priced device. I had great trouble with the moulding the sides collapsed during the process and the device was beyond recovery. BSSAA were very helpful and gave me another device free of charge and talked me through the moulding process. I tried again and had a degree of success in that my top set of teeth had a good degree of retention but the lower jaw had very poor retention so when asleep my mouth dropped open again. BSSAA recommended the Tomed SomnoGuard AP, and I watched the video showing the moulding process. It looks to me to be the solution as the retention seems superb together with incremental adjustment for the advancement of the jaw …… but another £130! Given my time again, I think that I would have gone for this but I did struggle with forking out £130 which is why I experimented with the cheap options, now I have spent around £80 and have a couple of nasty plastic blobs of no value to me …… I guess I could try selling them to the Tate Modern! My advice would be …… go for the Tomed SomnoGuard AP rather than SomnoGuard 3 as the moulding process and retention seems superior.
Last hope
I have been causing havoc at home for a few years – with me either destroying my wifes sleep or swapping bedrooms with one of the children. After another bad nights sleep I trawled the internet and thankfully found this website. Cost looked high for what looked like a fairly regular rugby gum shield. Completely wrong, this worked for me. Took a few days to become used to the feel and best way to use the thing. I do now ensure I have a drink/ clean teeth at least ten minutes before using. Otherwise extra saliva takes time to settle down. Teeth do feel a bit odd in the morning but very soon settle down. 9 times out of ten shield still in my mouth in the morning. Not one complaint of snoring since started use. Not sure if long term the dentist will have concerns but got to be worth it.
Well, it works
Every morning I would be called Mrs Snorehead. Now? I ask if I snored, and my husband replies that he doesn’t think so. Essentially, it works. Yes, it makes your lips and mouth dry, and there’s a bit if excess salivation when it first goes in at night, but that’;s a small price to pay. I usually wake up lying on it anyway so I guess I spit it out, but no more moaning husband.
Tomed Somnoguard 3
Snored for years. Needed to try something and looked at various devices. Tried this product first as not so expensive. Arrived quickly by post. Instructions quite detailed but lots of possible pitfalls when fitting. Not too easy to fit. When putting in boiling water it does soften quickly. You have to work quickly. My first try was not too good and had to do it a second time. It’s fits my mouth fine but not perfectly. If I get another one I think I’d get the fit a lot better. In use, my wife says its making my snoring lower and at a reduced level, so good news. At first it does make your jaw ache, and is initially uncomfortable having something in your mouth. You do get used to it after a few days. I thought I would dribble but haven’t done so but my lips can get dry in the night. Have not slept through whole night with it, have woken and taken it out but replaced it later so nearly a full night. I’d get another one and try fit it better next time. Long term there is a stainless steel product available which is smaller and lighter on your mouth/jaws; the only downside it costs @ £1400. Time to start saving.
