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 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 carefully follow the detailed instructions included with your product.
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 10 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.
