Yes, mandibular advancement devices known as MADs are highly effective at reducing or even eliminating snoring. In 2026, these devices are widely recognised by UK medical and dental professionals as a primary treatment for habitual snoring and mild to moderate obstructive sleep apnoea. They are particularly successful for people whose snoring is caused by the tongue falling back into the throat during sleep.
A mandibular advancement device is a specialised oral appliance that fits over your teeth, similar to a sports gum shield. It works by gently holding your lower jaw and tongue in a forward position. This mechanical adjustment widens the airway at the back of the throat, preventing the soft tissues from collapsing and vibrating, which is the physical cause of snoring sounds.

How these devices open the airway
The primary function of a mandibular advancement device is to create more space for air to pass through the throat.
- Lower Jaw Positioning: By pulling the mandible known as the lower jaw forward, the device creates tension in the tissues of the upper airway, making them less likely to flop and vibrate.
- Tongue Stabilisation: The forward position of the jaw naturally pulls the base of the tongue away from the back of the throat, which is a major site of obstruction for many snorers.
- Respiratory Stability: With a wider and more stable airway, the turbulence of inhaled air is reduced, leading to quieter and more consistent breathing throughout the night.
Effectiveness for snoring and sleep apnoea
In the UK, the success of these devices is well documented, especially for patients who find other treatments like CPAP machines difficult to use.
- Snoring Reduction: The majority of users report a significant decrease in snoring volume and frequency. For many, the device provides a near total resolution of the sound.
- Mild to Moderate OSA: MADs are a clinically proven treatment for obstructive sleep apnoea. While they may not be as powerful as CPAP for severe cases, they are often preferred for their comfort and portability.
- High Success Rates: Success is highest in patients with a lower body mass index and those whose snoring is positional, such as only occurring when sleeping on their back.
Comparison: Custom Made vs Over the Counter Devices
| Feature | Custom Made Dentist Provided | Over the Counter Boil and Bite |
| Fit and Comfort | Precise: made from dental impressions | General: moulded at home in hot water |
| Adjustability | High: can be titrated in millimetres | Low: often fixed in one position |
| Durability | Long lasting: typically 18 to 36 months | Short term: often needs replacement |
| Effectiveness | High: targeted for individual anatomy | Variable: may not stay in place |
| Cost | Higher: includes professional fees | Lower: affordable initial investment |
| Jaw Health | Safer: monitored by a dentist | Risky: may cause more jaw strain |
Side effects and adjustment
While effective, wearing a device that repositions your jaw requires a period of adaptation.
- Short Term Discomfort: It is common to experience jaw muscle stiffness, tooth tenderness, or increased salivation during the first week or two of use.
- Temporary Bite Changes: You may notice that your teeth do not quite fit together correctly immediately after waking up. This usually resolves within an hour of removing the device.
- Long Term Dental Shifts: Over several years of use, minor permanent changes to the bite or tooth alignment can occur. This is why annual dental reviews are recommended for long term users.
- Contraindications: These devices are not suitable for people with severe gum disease, loose teeth, or significant jaw joint issues like TMJ disorder.
To Summarise
Mandibular advancement devices are a powerful and non invasive solution for reducing snoring and managing mild sleep apnoea in the UK. In 2026, the technology behind these devices has advanced to allow for thinner, more comfortable designs that do not significantly disrupt sleep. While over the counter options are a useful starting point to see if the technology works for you, a custom made device provided by a dentist offers the best balance of effectiveness and long term safety. By keeping the airway open, these devices restore quiet sleep for the snorer and their partner while protecting long term respiratory health.
If you are a habitual snorer, consider speaking with your dentist or GP to see if you are a good candidate for a mandibular advancement assessment.
Do I need to see a doctor before getting a snoring device?
In the UK, it is highly recommended to speak with a GP or dentist first. This ensures that your snoring is not a symptom of severe sleep apnoea that requires a more intensive treatment like CPAP.
How do I know if my snoring is tongue based?
A simple test is to try to make a snoring sound while sticking your tongue out as far as it can go. If the snoring sound is reduced or stopped, a mandibular device will likely be very effective for you.
Can I wear a mandibular device with dentures?
Generally, no. These devices require healthy, stable teeth to hold the jaw in place. If you have full dentures, you may need to explore other options like positional therapy.
Will the device make me drool?
Increased salivation is very common during the first few nights as the brain treats the device like food. This usually stops once the mouth becomes accustomed to the device.
How do I clean my mandibular advancement device?
You should clean it every morning with a soft toothbrush and cool water or a specialised cleaning solution. Avoid using toothpaste as it can be abrasive.
Can children use these devices for snoring?
No. Mandibular advancement devices are for adults whose jaws have stopped growing. Snoring in children is often caused by enlarged tonsils and requires a paediatric assessment.
