TL;DR: A dentist-fitted snoring mouthguard, properly called a mandibular advancement device, typically costs from around £40 for a boil-and-bite version to about £100 for a semi-bespoke device, with custom dentist-made splints costing more. The NHS rarely provides them unless a hospital sleep clinic has diagnosed sleep apnoea and prescribed one.
Snoring affects a huge share of UK households: a representative UK survey found that 38% of men and 30.4% of women report snoring at night [14]. If you have searched for a solution, you have probably seen mouthguards advertised at wildly different prices, from £30 gadgets online to four-figure private quotes. This guide explains what these devices are, what a dentist actually charges, when the NHS will and will not help, and what the clinical evidence says, using only official UK sources.
What is a snoring mouthguard (mandibular advancement device)?
A snoring mouthguard is formally known as a mandibular advancement device (MAD) or mandibular advancement splint. The National Institute for Health and Care Excellence (NICE) defines it as an oral device worn over the upper and lower teeth that "holds the lower jaw forward, thereby increasing space at the back of the mouth and decreasing snoring and sleep apnoea" [2]. By gently repositioning your lower jaw while you sleep, the device keeps the airway at the back of your throat more open, which reduces the vibration that causes the snoring sound.
The NHS lists mandibular advancement devices among the treatments for snoring caused by the tongue partially blocking the back of the throat, alongside options such as vestibular shields, chin straps and nasal strips [3]. For obstructive sleep apnoea, the NHS describes the device as "a device like a gum shield that holds your airways open while you sleep" [4].
There are three broad types, and the differences matter for both price and fit:
- Boil-and-bite devices: softened in hot water and moulded at home. The cheapest option, available from pharmacies and online.
- Semi-bespoke (semi-customised) devices: you take a dental impression at home with a kit and post it to the manufacturer, which makes the splint to your impression [2].
- Fully bespoke (custom-made) devices: a dentist takes a professional dental impression, a laboratory makes the splint, and a suitably trained dentist fits and adjusts it [2].
How much does a snoring mouthguard cost in the UK?
Published prices for snoring mouthguards contradict each other across the internet, so the figures below come from NHS trust patient information rather than retailer marketing. University Hospitals Birmingham NHS Foundation Trust, one of the UK's largest trusts, gives these guide prices in its intraoral devices patient leaflet [9]:
| Device type | Typical cost | How you get it |
|---|---|---|
| Boil-and-bite | Around £40 | Pharmacy or online, self-moulded at home |
| Semi-bespoke | Around £100 | Impression kit posted to the manufacturer |
| Fully bespoke (dentist-made) | More expensive, individual private dentist fee | Impression, fitting and adjustment by a trained dentist |
Neither of the two NHS trust leaflets reviewed for this article puts a specific figure on a fully bespoke, dentist-made device. Both describe it as the best option but more expensive than the semi-bespoke route [9] [10]. In practice the price is set by the individual private dental practice and depends on the laboratory, the device brand and how many adjustment appointments are included, so ask for a written quote and treatment plan before committing. Our guide to private dentist prices in the UK explains how private fees are set and how to compare quotes.
The British Snoring and Sleep Apnoea Association, a UK charity, lists boil-and-bite examples at roughly £30 to £57 and adjustable semi-custom devices at around £127, which is consistent with the NHS trust guide prices above [16].
Interestingly, the semi-bespoke middle tier may be the sweet spot. The UHB leaflet, citing a UK clinical trial, describes the semi-bespoke device as "the most cost-effective" intraoral device [9]. That trial is covered in the effectiveness section below.
Can you get a snoring mouthguard on the NHS?
For most people the honest answer is no. The NHS Business Services Authority (NHSBSA), which administers NHS dental charges, states the rule directly [5]:
"Anti-snoring devices including Mandibular Splints are not normally available on the NHS unless the patient has been diagnosed with sleep apnoea from a current secondary care NHS consultant and they've been given a treatment plan that states an anti-snoring device is needed."
Queen Victoria Hospital NHS Foundation Trust puts the same rule even more plainly in its patient leaflet: "Pure snoring without diagnosed sleep apnoea is not eligible for treatment within the NHS" [10]. And University Hospitals Birmingham tells its sleep patients that intraoral devices "are not usually provided on the NHS and have to be purchased either over the counter from pharmacies or online" [9].
There is also a structural gap behind this. The OSA Alliance, a UK umbrella group of sleep medicine organisations, reports that "there is currently no pathway in place for access to MAS through the NHS", so access varies by area and many patients who cannot tolerate the standard NHS treatment have to self-fund a device [11]. This is an active campaigning position from the sleep medicine sector, not a description of an entitlement, and it explains why your experience may differ depending on where you live.
What you pay if the NHS does provide one
Where an NHS consultant has diagnosed sleep apnoea and prescribed a device on a treatment plan, the device is provided through NHS dentistry under the standard charge bands in England. According to NHSBSA, a laboratory-made device falls under Band 3, which costs £332.10 from 1 April 2026, while a non-laboratory device falls under Band 2a [5] [6]. For context on how the bands work, see our complete guide to NHS dental charges. These band figures apply to England only; Scotland, Wales and Northern Ireland run their own NHS dental charging systems, so check the equivalent arrangements if you live outside England.
The usual NHS exemptions apply to the band charge. You pay nothing for NHS dental treatment if, among other categories, you are under 18 (or under 19 and in full-time education), pregnant or within 12 months of giving birth, receiving qualifying benefits such as Income-related Employment and Support Allowance or Pension Credit Guarantee Credit, or covered by an HC2 certificate under the NHS Low Income Scheme [7]. Our free NHS dental treatment eligibility guide covers every category in detail. Note that these exemptions remove the charge for treatment the NHS has agreed to provide; they do not make a snoring device NHS-fundable in the first place.
CPAP is the NHS route for sleep apnoea
If your problem is diagnosed obstructive sleep apnoea rather than simple snoring, the standard NHS treatment is continuous positive airway pressure (CPAP), a small machine that gently pumps air into a mask worn during sleep. The NHS states that it provides CPAP machines free of charge [4]. Mouthguards enter the NHS picture mainly as an alternative for people who cannot get on with CPAP, which is exactly how NICE frames them.
Do snoring mouthguards actually work?
The strongest UK evidence comes from TOMADO, a randomised controlled crossover trial in adults with mild to moderate obstructive sleep apnoea, published in the journal Thorax and the Health Technology Assessment programme [12]. Compared with no treatment, the trial found that mandibular advancement devices reduced the apnoea-hypopnoea index (AHI, the standard measure of breathing interruptions per hour of sleep) by 26% for a self-moulded device, 33% for a semi-bespoke device and 36% for a fully bespoke device [12]. All three device types also produced meaningful improvements in daytime sleepiness scores, and all were judged cost-effective, with the semi-bespoke device the best value [12].
Against CPAP, the picture is more nuanced. A systematic review and meta-analysis published in a peer-reviewed journal found that CPAP was significantly more effective than mandibular advancement devices at suppressing AHI, but there was no significant difference between the two treatments in improving reported daytime sleepiness [13]. The review concluded that CPAP remains the gold standard, with oral appliances the recommended alternative for patients who cannot tolerate it [13]. That is precisely the position NICE takes in its national guideline.
One honest caveat: for simple snoring without sleep apnoea, the evidence base is thinner. NICE's guideline covers obstructive sleep apnoea and makes no recommendation on simple snoring, and NHS trust information notes that a device "may not cure snoring or sleep apnoea, it may minimise it" [9]. A device that works well for one person's snoring may do little for another's, because snoring has several different causes [3].
What NICE recommends, and who a mouthguard is for
NICE guideline NG202, covering obstructive sleep apnoea/hypopnoea syndrome (OSAHS) in over-16s, sets out exactly when a mandibular advancement splint should be considered [1]. For mild OSAHS with symptoms that affect daytime activities, recommendation 1.5.7 says:
"If a person with mild OSAHS and symptoms that affect their usual daytime activities is unable to tolerate or declines to try CPAP, consider a customised or semi-customised mandibular advancement splint as an alternative to CPAP if they: are aged 18 and over and have optimal dental and periodontal health."
The same conditions apply for moderate and severe OSAHS under recommendation 1.6.6 [1]. Two details in that wording matter for patients:
- You must be 18 or over. NICE's recommendations on these splints are for adults only [1].
- Your teeth and gums must be healthy first. NICE flags that semi-customised splints may be inappropriate for people with "active periodontal disease or untreated dental decay; few or no teeth; generalised tonic-clonic seizures" [1]. If your gums bleed or you have untreated decay, that needs sorting before a device is fitted; our guide to gum disease treatment costs explains what treatment involves.
NICE also expects proper follow-up rather than fit-and-forget: its guideline recommends an initial review of device adjustment and symptom improvement at 3 months, then further follow-up until symptoms are optimally controlled [1].
Who actually fits the custom devices? NICE's own definition specifies that a custom-made splint is formed from a dental impression taken by a dentist and "fitted by a suitably trained general dental practitioner" [2]. Not every dentist offers this, so it is worth asking specifically about dental sleep medicine experience when choosing a practice. Our guide on how to find a good dentist in the UK covers the checks worth making before you book.
Side effects and who should not use one
Mandibular advancement devices are low-risk compared with surgery, but they are not side-effect free. NHS trust patient leaflets list the common effects [9] [10]:
- Jaw ache and tenderness of the facial muscles or jaw joints
- Tooth pain or discomfort
- Dry mouth, or the opposite, excessive salivation
- An altered bite or difficulty finding your normal bite on waking
- The snoring or apnoea not resolving
Most of these settle with time [9]. One symptom should always stop you using the device: teeth that begin to feel loose or mobile. University Hospitals Birmingham advises that if this happens, "IOD therapy should be stopped" and you should seek advice from your dentist [9].
Some people should not use these devices at all, or need specialist advice first. Drawing together NICE guidance and NHS trust information, that includes people with active gum disease or untreated decay, people with few or no teeth to anchor the device, people with complete dentures, under-18s, people with generalised tonic-clonic seizures, and people with severe asthma [1] [9]. Temporomandibular joint disorder (TMJD) is also a reason for caution, as the device works the jaw joint all night; if you already have jaw clicking or pain, read our guide to jaw pain and TMJ disorders and speak to a dentist before buying anything.
Snoring mouthguard vs night guard for teeth grinding
These two devices are frequently confused, and they are not interchangeable. A mandibular advancement device is defined by NICE as a device that holds the lower jaw forward specifically to treat sleep-related breathing disorders such as snoring and sleep apnoea [2]. A night guard for teeth grinding (an occlusal splint) sits over the biting surfaces to protect tooth enamel from grinding and clenching forces; it is not designed to move your jaw forward or open your airway.
If your issue is grinding rather than snoring, a snoring mouthguard is the wrong device, and vice versa. Some people do have both problems, in which case a dentist can advise on the right combination. For grinding, see our dedicated guide to teeth grinding (bruxism) treatment and night guard costs.
When snoring needs a medical assessment first
Before spending anything on a device, rule out obstructive sleep apnoea, because a mouthguard bought online can quieten the noise while leaving a serious condition untreated. Research suggests obstructive sleep apnoea is far more common than most people assume, with an estimated prevalence of 17.8% among adults aged 40 to 64 in England, and up to 85% of people with moderate to severe sleep apnoea undiagnosed [15].
The NHS advises seeing a GP about snoring if lifestyle changes do not help, if snoring is having a big impact on your or your partner's life, or if you feel sleepy during the day, your breathing stops and starts while you sleep, or you make gasping or choking noises during sleep [3]. NICE recommends an assessment for sleep apnoea when someone has two or more symptoms from a list that includes snoring, witnessed breathing pauses, unrefreshing sleep, waking headaches and unexplained excessive sleepiness [1]. A GP can refer you to an NHS sleep clinic for testing [4].
There is a legal dimension too. Gov.uk states that you must tell the Driver and Vehicle Licensing Agency (DVLA) if you have confirmed moderate or severe obstructive sleep apnoea syndrome with excessive sleepiness, or any sleep condition that has caused excessive sleepiness for at least 3 months, and that "you must not drive until you're free from excessive sleepiness or until your symptoms are under control and you're strictly following any necessary treatment" [8]. You can be fined up to £1,000 for failing to tell the DVLA about a medical condition that affects your driving [8].
Getting assessed first is not a box-ticking exercise. It determines whether you qualify for free NHS treatment (CPAP), whether an NHS-prescribed device is even a possibility, and whether a self-funded mouthguard is a sensible purchase or a risky sticking plaster.
Frequently asked questions
Can a dentist give you a mouthguard for snoring?
Yes. A dentist can take a dental impression and have a custom mandibular advancement splint made in a laboratory, then fit and adjust it. NICE specifies that custom-made splints should be fitted by a suitably trained general dental practitioner, so ask whether the practice has dental sleep medicine experience before booking [2].
Does the NHS provide mouthguards for snoring?
Not normally. NHSBSA guidance states anti-snoring devices are only available on the NHS when a secondary care consultant has diagnosed sleep apnoea and included the device in a treatment plan [5]. Snoring without diagnosed sleep apnoea is not eligible for NHS treatment, so most people self-fund a device privately [10].
How much does a snoring mouthguard cost from a dentist in the UK?
NHS trust patient information gives guide prices of around £40 for a boil-and-bite device and around £100 for a semi-bespoke device made from a posted impression [9]. Fully bespoke dentist-made splints cost more, with the exact fee set by the individual private practice, so always request a written quote first.
Do snoring mouthguards actually work?
For mild to moderate sleep apnoea, UK trial evidence shows mandibular advancement devices reduce breathing interruptions by 26% to 36% versus no treatment and improve daytime sleepiness [12]. CPAP machines reduce apnoea more effectively overall [13]. For simple snoring without apnoea, evidence is weaker: devices may reduce snoring rather than cure it [9].
What is the difference between a snoring mouthguard and a night guard for grinding?
A snoring mouthguard (mandibular advancement device) holds your lower jaw forward to keep the airway open during sleep, treating snoring and sleep apnoea [2]. A grinding night guard (occlusal splint) covers the biting surfaces to protect enamel from clenching forces. They solve different problems and one cannot substitute for the other.
Are snoring mouthguards safe to buy online without seeing anyone?
Buying online is legal but risky if you have never been assessed. Loud snoring with daytime sleepiness, witnessed breathing pauses or gasping can indicate obstructive sleep apnoea, which needs a GP referral and sleep study first [3]. A device may mask symptoms of untreated sleep apnoea, and confirmed sleep apnoea with sleepiness also carries DVLA notification duties [8].
Who should not use a mandibular advancement device?
NICE and NHS guidance advise against or urge caution for under-18s, people with active gum disease or untreated decay, people with few or no teeth or complete dentures, people with generalised tonic-clonic seizures or severe asthma, and people with temporomandibular joint disorder [1] [9]. A dental check-up before fitting is essential in every case.
Do I need to tell the DVLA about sleep apnoea?
Yes, in defined circumstances. Gov.uk states you must tell the DVLA about confirmed moderate or severe obstructive sleep apnoea syndrome with excessive sleepiness, or any sleep condition causing excessive sleepiness for at least 3 months, and you must not drive until symptoms are controlled. Failing to notify risks a fine of up to £1,000 [8].
Finding the right help for your snoring
A snoring mouthguard from a dentist is a legitimate, evidence-backed option, particularly if you have mild to moderate sleep apnoea and cannot get on with CPAP, or you are a confirmed simple snorer who has already been checked for sleep apnoea. Go in with realistic expectations on price: around £40 to £100 for self-fit and semi-bespoke options, more for a custom dentist-fitted splint, and do not expect the NHS to fund it unless a sleep consultant has prescribed it.
Start with the right sequence: rule out sleep apnoea with your GP first, get your teeth and gums checked, and then choose the device tier that fits your budget with professional advice. If you need a dental check-up before a device can be fitted, or want to talk through custom options with a professional, you can search for a dentist near you on Dentists Closeby and compare practices in your area.
