Anti-snoring device: custom-made and fitted by a dentist

An anti-snoring device is a custom-made dental appliance worn at night that holds the lower jaw slightly forward to keep the airway more open. At Dental & Wellness London we make dentist-fitted devices for people whose snoring has been assessed medically, and we are clear about what a dental appliance can and cannot do. This page explains how the device works, how it differs from retail mouthguards, who it suits, the process, aftercare and cost.

What an anti-snoring device is, and how it works

Snoring is the sound of soft tissue vibrating. As you fall asleep, the muscles that hold the airway open relax. Where the airway at the back of the throat is partly narrowed, the soft palate, uvula and base of the tongue flutter as air passes, and that flutter is the noise.

A custom anti-snoring device, known clinically as a mandibular advancement device (MAD) or mandibular advancement splint, is a pair of thin, linked trays that fit over the upper and lower teeth. It holds the lower jaw a few millimetres forward of its resting position. Because the tongue is attached to the lower jaw, it comes forward too, widening the space behind it so there is less loose tissue to vibrate. That small, controlled movement is the whole mechanism.

Most dentist-made devices are titratable: the amount of advancement can be increased in small steps. That matters, because too little does nothing and too much strains the jaw joint. The aim is the smallest movement that settles the snoring comfortably.

See your GP first: why medical advice comes before any device

Snoring can be harmless, or it can be a sign of obstructive sleep apnoea, a medical condition in which breathing repeatedly stops and starts during sleep. Dentists do not diagnose or treat sleep apnoea. Your GP, and where needed a sleep physician, diagnoses and manages it, often through a sleep study that can be done at home.

For that reason we make an anti-snoring device only after medical advice. Before we start, we ask that your GP has assessed your snoring. Speak to your GP promptly if you or your partner notice any of these:

• pauses in breathing during sleep, followed by gasping or choking;
• heavy daytime sleepiness, or falling asleep during the day or at the wheel;
• waking unrefreshed despite a full night, or morning headaches most days;
• high blood pressure alongside loud, habitual snoring.

Where a sleep physician has diagnosed sleep apnoea and recommends an oral appliance as part of their management, we can make and fit it to their recommendation, while the medical care stays with them. Our snoring and sleep apnoea page explains the condition and the pathway in more detail.

Custom anti-snoring mouthguard or retail device: the options compared

Search for an anti-snoring device in the UK and you will find everything from chemist-shelf products to dentist-made appliances. They are different products doing different jobs.

• Boil-and-bite mouthguards: softened in hot water and bitten into for a rough fit. They cannot be set to a precise advancement, tend to be bulky and wear quickly, and nobody checks your teeth or jaw joint first.
• Mail-order "custom" kits: you take your own impressions at home and a laboratory makes the device. The fit is better, but there is still no examination of your gums, teeth or jaw joint, and no one to adjust it.
• A dentist-fitted custom anti-snoring mouthguard: made in a laboratory from accurate impressions or a digital scan, in durable material, set to a measured bite position and adjusted over the following weeks. It is fitted only after the teeth, gums and jaw joint that support it have been examined.
• Other approaches: chin straps, nasal dilators, positional aids and mouth tape. Some help some people, particularly where snoring is mainly nasal; our article on mouth tape for sleep looks at one of them honestly.

For moderate or severe sleep apnoea, a sleep physician will usually recommend CPAP, a mask that holds the airway open with gentle air pressure. A dental device does not replace that advice. Our article do anti-snoring devices actually work sets out the evidence in more depth.

Who an anti-snoring device suits, and who it does not

Usually a good fit

• Simple, habitual snoring that disturbs a partner, where your GP has assessed you and sleep apnoea is not a concern, or a sleep physician has recommended an oral appliance.
• Snoring that is worse on your back and where the lower jaw tends to sit back.
• Enough healthy, stable teeth in both arches to anchor the device, with healthy gums.

Usually better managed another way

• Signs of sleep apnoea that have not yet been assessed medically: see your GP first.
• Snoring that is mainly nasal, from congestion, allergy or a deviated septum, where moving the jaw does little.
• Active gum disease, loose teeth, too few teeth to anchor the device, or an unmanaged jaw-joint problem; see jaw pain and TMJ.
• Snoring driven mostly by alcohol timing, sleep position or recent weight change, where simpler steps come first. Our guide on how to stop snoring covers them.

We say no when a device is not the right answer, even if it means you do not become a patient.

The process, step by step

1. Discovery call. A free 20-minute phone call to talk through your snoring, what your GP has advised, and whether a device is likely to help.
2. Dental examination. A 30-minute examination (£65) with a full risk assessment. We check the teeth that will anchor the device, the gums, the bite and the jaw joint, measure how far your lower jaw moves forward comfortably, and confirm the medical advice you have had.
3. Records. We take a digital scan or impressions of both arches and record the starting bite position. The laboratory builds the device to those records.
4. Fitting. We check fit and comfort, set a conservative starting advancement, and show you how to put it in, take it out and clean it.
5. Adjustment. Over the following two to four weeks the device is advanced in small steps until snoring settles at the smallest effective movement. We review you to fine-tune the setting and check your bite and jaw.
6. Medical follow-up. Where a sleep physician is involved, they may arrange a follow-up assessment with the device in place. We share our notes with them if you wish.

Results, longevity and aftercare

Many people and their partners notice less snoring once the device has been adjusted, but results vary and no device stops snoring for everyone. For the first week or two you will be aware of it; mild morning jaw or tooth tenderness and extra saliva are common and usually settle.

A custom device typically lasts three to five years with proper care, depending on the material and whether you also grind your teeth. Aftercare is simple:

• Rinse and brush the device gently each morning with cool water, let it dry, and store it in its case. Never use hot water, which distorts the material.
• Keep up good home care and regular dental hygienist visits (30 minutes, £85), because healthy teeth and gums anchor the device.
• Bring the device to your routine examinations so we can check its fit and your bite.

Risks, and how we reduce them

• Jaw-joint or muscle discomfort. We assess the joint first, start with a conservative setting and advance gradually.
• Tooth tenderness and bite changes. Some people notice their bite feels different for a short time each morning; a small number develop longer-term changes in how the teeth meet. Regular reviews let us spot this early.
• Masking a medical problem. Quieter snoring does not mean sleep apnoea has been excluded. That is why medical advice comes first, and why we ask you to return to your GP if daytime sleepiness or breathing pauses continue.
• Grinding. If you also clench or grind, we take it into account in the device design; see teeth grinding and bruxism.

Why choose us for an anti-snoring device

Devices are assessed and fitted by Dr Vishal Patel, BDS (Liverpool), MSc Aesthetic & Restorative Dentistry (Manchester), GDC 103127, an AACD member with around 20 years in dentistry and over 15,000 cases. As an Invisalign Diamond II provider, in the top 1% of UK Invisalign providers, he works daily with precise jaw records, bite registration and small, controlled tooth and jaw movements, which is exactly the discipline a well-adjusted device needs.

We also look at the wider picture. Snoring, grinding, mouth breathing and jaw tension often travel together, so where it helps we connect your care to our airway dentistry approach and to sleep dentistry more broadly, while keeping the medical side with your GP.

Questions patients ask about anti-snoring devices

Do anti-snoring devices work?

For many people with simple snoring, a custom mandibular advancement device reduces snoring noticeably once it has been adjusted, but results vary. They work less well when snoring is mainly nasal or driven by alcohol or sleep position. A device should only be made after your GP has assessed you, because snoring can be a sign of sleep apnoea.

Can I get an anti-snoring device on the NHS?

Availability varies. The right first step is your GP, who can assess your snoring and arrange a sleep study if sleep apnoea is suspected; diagnosis and treatment of sleep apnoea sit with NHS sleep services. Custom devices for simple snoring are usually provided privately. We are a private practice and do not offer NHS treatment.

Is a custom device better than a boil-and-bite mouthguard?

A custom device is made from accurate records of your teeth, set to a measured jaw position and adjusted gradually, after a dentist has checked your teeth, gums and jaw joint. Boil-and-bite guards fit roughly, cannot be finely adjusted and wear faster. For occasional use they may help some people, but they are not the same product.

Do I need a Harley Street clinic for snoring treatment?

No. What matters is the pathway, not the postcode: medical assessment by your GP or a sleep physician first, then, where a dental appliance is appropriate, careful fitting and adjustment by an experienced dentist. We provide that dental part at 222 Essex Road in Islington, N1, a short journey from central London.

Will an anti-snoring device change my bite?

Some people notice their bite feels slightly different for a short time after removing the device in the morning; this usually settles within an hour. A small number develop longer-term changes in how the teeth meet. We start conservatively, advance gradually and review your bite regularly so any change is caught early and managed.
