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.

Miraculous!
Your product has practically saved my marriage! It is so hard, sleeping with someone who snores, both on the in and the out breath..too little sleep makes you fed up, grumpy and eventually, ill…and very cross with the person who is causing it. Your MAD has stopped all snoring, totally. I cannot tell you how grateful I am. Thank you .
SomnoGuard 3 feedback
I have been using the SomnoGuard 3 for nearly two weeks and I am very pleased with the product. My wife is the only person who can vouch for it’s effectiveness. Before I got the SomnoGuard 3, most nights she was being awakened by my snoring but since I started using it she hasn’t heard me snoring since. It took me about a week to get used to it but I am glad I bought it.

This little product is literally life changing. I tried all manner of anti-snoring options over the years, even having surgery on my nasal septum. Nothing made the slightest difference. Then I discovered somnoguard through this website and was able to move back out of the spare room. It takes a few weeks to get used to it. Initially you wake up dribbling or lie on it having spat it out. However once you get used to it you have a comfortable peaceful night’s sleep and your spouse does too! Thanks
wasted money
it arrived quick enough, followed the instructions to set the mouth piece tried it and there was a little improvement but the day after I tried to remould it slightly to move jaw forward and made a complete mess of it. Third attempt its so out of shape its useless and you cannot reshape it anymore. Cannot recommend it
Excellent. Snoring at a minimum.
This is my second Somnoguard over the years.I have obstructive sleep apnoea, am 41 and female.I had a UPPP in January and suffered5m 5 weeks of pain and it made only 10% difference to my snoring so Ive gone back to the Somnoguard 2.My snoring score is down from 90% to 7% and some nights I don’t snore at all. I use an app that records my sleep and snore pattern.Very easy to use and mould to the mouth and gums and fits perfect when asleep. Dentist has assured me that it doesn’t affect teeth or gums. I couldn’t be without it now.
