The best anti-snoring device is only prescribed after you’ve been screened for Obstructive Sleep Apnoea / Apnea (OSA).
The best one:
Stops your snoring
Costs you the least money (because it isn’t a false economy)
Creates the least side-effects (and helps you sleep and breathe at the same time)
So, if you’re wondering what’s the best anti-snoring device, then read this independent (no advertisements or affiliate links!) sleep-industry expert review.
These devices, which in their simplest form loosely resemble an athlete’s mouth guard, help open your airway by bringing your lower jaw (mandible) and tongue forwards while you sleep.
This movement (known as ‘protrusion’) increases the space behind your tongue. While a dentist-made appliance may appear expensive, ‘cheaper’ do-it-yourself kits are available.
This independent, expert review examines the pros and cons of custom-made versus DIY anti-snoring devices.
If you have difficulty breathing through your nose, address this before you consider an oral appliance. Consult your GP if the issue persists.
While an oral appliance should not stop you breathing through your mouth, it will certainly present a restriction.
Nasal breathing is ideal. Read more about this in my post about snore-relief products available without prescription.
The latest NICE Guidelines (National Institute of Health and Care Excellence) for the United Kingdom, describe an anti-snoring device as below. Check out their interactive pathway for obstructive sleep apnoea.
A mandibular advancement splint is an oral device used to treat sleep-related breathing disorders. It is worn over the upper and lower teeth, and holds the lower jaw forward, thereby increasing space at the back of the mouth and decreasing snoring and sleep apnoea. A custom-made mandibular advancement splint is formed from a dental impression taken by a dentist, which is used to make the splint in a laboratory. It is then fitted by a suitably trained general dental practitioner. A semi-customised mandibular advancement splint is formed using a dental impression taken by the patient, which they send to the manufacturer to make the splint.
Anti-snoring devices (Mandibular Advancement Devices – MADs) or ‘gumshields for snoring’ are big business on the internet and in some pharmacies, typically when self-help fails.
Despite the lack of prior sleep apnoea screening.
Indeed, the United Kingdom’s NHS website makes reference to MADs but fails to differentiate between custom-made and Over-the-Counter (OTC) snore-stoppers!
How to choose one that actually works?!
Snoring aids and cures are increasingly popular as we recognise the impact poor sleep has upon our health, daytime functioning and work performance.
A news article “Ten Snoring Cures” reviewed 10 ‘cures’ available in the UK.
The journalist tried to stop his own snoring, with chin straps, sprays, pillows and ‘gumshields’, aka anti-snoring devices.
He had little success and concluded his review by quoting a UK snoring expert, Consultant Respiratory Physician, Dr Tom McKay, from Edinburgh Royal Infirmary Sleep Centre, UK, as saying:
‘Sprays don’t have any great effect although nasal steroids have a small role if you’ve got nasal congestion. It can help to lose weight or avoid alcohol last thing at night or to sleep lying on your side. Various forms of gumshield are reasonably successful – maybe 50 or 60 per cent.’
So, its a reasonable question to ask….
‘Gumshields for snoring’ could more accurately be described as mandibular advancement devices (MADs).
They are also known as intra-oral devices, mandibular repositioning devices (MRDs) or even sometimes mandibular advancement splints (MAS) !
But there are essentially just two categories:
Over-the-Counter (OTC) ‘gumshields’
Prescription, Custom-Made Dental Appliances
In this updated for 2022 review, I examine how both categories of anti-snoring device measure up against my Top 13 criteria for choice (see call out box) to determine which ones really work, and if they’re safe and effective.
Each section concludes with my verdict and there’s a free bonus at the end!
if you are looking for impartial advice about snoring from an expert in the field, the highly respected Adrian Zacher should be your go to. We applaud Adrian’s work, to raise awareness about the health implications of snoring, and the importance of prescription, custom made devices for long-term success
Snoring may be a symptom of obstructive sleep apnoea/apnea (OSA).
Without first being screened for OSA your purchase of an OTC anti-snoring device, could harm you and if you snore because you have undiagnosed Obstructive Sleep Apnoea (OSA) the OTC gadget delays effective (and free on the NHS!) treatment that will prolong your healthy life.
Consult a sleep-trained pharmacist to learn how to stop your snoring.
The pharmacist will screen you for OSA and decide if you’re ‘just’ a snorer or if your snoring needs investigating.
Your GP may be able to help you – but they may not know much about sleep apnoea as sleep is not part of core medical training. We provide expert written GP Guidelines to help.
In the UK, you can also find sleep-trained dentists who can screen you and recognise Obstructive Sleep Apnoea/Apnea (OSA) symptoms2, make custom anti-snoring devices for snorers, without a prior medical diagnosis, or if they suspect OSA refer you on for further investigation.
Oral appliance therapy is considered a second-line option for OSA (which means that PAP is first-line [the first treatment option] and only after PAP failure would an oral appliance for OSA be considered).

Medical and dental experts review medical devices (clinical research) to establish if they work.
Their research produces data and information which can be thought of as ‘proof’ that something does or does not work, and how well it works in certain circumstances.
The evidence they create is also judged for quality.
When selecting an anti-snoring device, it’s important to look at this clinical evidence.
To judge the quality of a mandibular advancement device’s (MAD’s) clinical research evidence, you need to look past the headlines claiming “Clinical research– tick”.
What was the outcome of the research?!
Measurement of what patients perceive as important effects from wearing an MAD typically include:
Gumshields or ‘Boil-and-Bite’ anti-snoring devices, have been clinically researched head-to-head against custom-made, prescription, adjustable anti-snoring devices and found to be lacking.
Our results suggest that the thermoplastic device cannot be recommended as a therapeutic option nor can it be used as a screening tool to find good candidates for mandibular advancement therapy.3
…patients overwhelmingly found the ready-made MRD difficult to tolerate…4
…96% of patients reported minor adverse events, which related predominantly to discomfort.4 [referring to a study by Dr. Tim Quinnell 5
Today, clinical research has established that custom made MADs are first-line therapy (the default first option) for snoring and mild obstructive sleep apnoea / apnea.
Predictors of satisfactory outcome before purchase (who will benefit and why) and which type of custom made MAD is most effective for a given genotype (which MAD is best for YOU as opposed to a vanilla approach).
A positive outcome from clinical research can be thought of as a ‘guarantee’ of sorts.
My advice is to do your homework (grab the Bonus Mouthpiece Guide at the end) and be guided by a sleep-trained dentist. You can find one via our Links page.
[Note: Below is an advanced topic about typical MAD research metrics. So, if you’re new to clinical evidence, feel free to skip this tip].
OTC gumshields and ‘treatments’ might appear cheaper than custom-made, prescription appliances & dentist fees, BUT…
Are they a false economy?
Financially, its tempting to cut out the dentist.
After all, a large part of the cost to you when purchasing a mandibular advancement device, is their clinical time.
The device fees vary, but what are you paying for?
That is what they do.
While Dentistry may initially seem expensive, the risks of not using an expert are considerable.
Remember, you are relying on the anti-snoring device to hold open your airway while you sleep. Think carefully before you choose.
Some dentists are specially trained in snoring and sleep apnoea / apnea, known as sleep-related breathing disorders (SRBD) and work closely with medics.
Dentists with a special interest in sleep, can help you find the correct balance of benefits versus side-effects.
If you have certain medical conditions, or grind your teeth, you might break an OTC ‘gumshield’ whilst you’re asleep. When you are asleep you cannot spit out pieces of a broken gadget. You could INHALE or SWALLOW pieces.
You can find sleep-trained dentists on our Links page. In the UK, look for the British Society of Dental Sleep Medicine.
Don’t do it.
The terrifying thought of bits of MAD breaking off and being inhaled while you sleep, should surely make you realise you need to see a sleep-trained dentist and use a prescribed custom-made, adjustable anti-snoring appliance, made to quality standards.
In case you’re wondering, I’m not a dentist.
Then read our free, definitive step-by-step how to stop snoring Guide.
An MAD that is so uncomfortable to wear, soon ends up being thrown across the bedroom or just left in the bathroom at bedtime…
Both the design and clinical expertise in how an anti-snoring device is supplied, directly impacts your likelihood of successfully wearing it (and therefore whether it stops your snoring) – particularly during the first two weeks of use.
This is when most people who aren’t going to get on with them, quit. It might seem obvious:
but if you don’t wear it – it doesn’t work.
Generally OTC gumshields for snoring are “one-size-fits-all”. They have to be bulkier in size to adapt to your teeth than custom-made devices.
This would mean it feels like you are squeezing a tennis ball into your mouth – Oh, and then you’re expected to sleep!
A sleep-trained dentist will ensure that your MAD fits properly and doesn’t hurt.
They will also ensure you know how to put the device into your mouth and get it out again.
As a general rule, custom-made anti-snoring devices are less bulky than ‘gumshields’.
Due to the lack of accuracy of the ‘fit’ and one-size-fits-all approach of gumshields, they may be too large, too small or take up so much room in your mouth you can’t close your lips and you find yourself dribbling attractively!
You wear these things in your mouth.
What impact will it have?
Its quite possible that a gumshield will place excessive load upon an individual tooth/teeth.
Over time your teeth will move. It will hurt.
And you will either:
An expert sleep-trained dentist can help identify (and save that tooth) if it could not withstand the lateral loading required.
A dental technician would ‘block out’ the identified tooth and not include it in the custom-made device.
All anti-snoring devices will aggravate your oral hygiene.
However, a sleep-trained dentist would ensure BEFORE you had an MAD, that your hygiene and oral condition (teeth, gums and jaw-joints) were satisfactory before you began to use it.
Try to keep the device as clean as possible. Use your toothbrush and toothpaste on it each morning. Don’t use chlorine based denture cleaners on gumshield based devices – it makes them hard and brittle (unusable) rapidly. Instead, use a baby bottle sterilising fluid (follow the manufacturer’s instructions).
Brush and floss your teeth carefully and consider using a chlorhexidine mouthwash. If you spit blood when you clean your teeth consult a dentist/hygienist.
‘Boil-and-Bite’ devices will flex when worn and over time, this will procline (tilt forwards) your lower incisors and retrocline (tilt backwards) your upper incisors.
Certain custom-made anti-snoring devices are designed to avoid this tooth tilting movements.
Consult your sleep-trained dentist.
Jaw pain is truly horrible and once you have a jaw pain problem it persists.
All types of mandibular advancement device (MAD) work by moving your lower jaw forwards, and the amount it does this to be effective, and not hurt too much, is specific to you.
While of course it won’t initially prevent snoring in this position, the dentist will gradually advance your jaw until you stop snoring over a matter of weeks or perhaps even longer (this is known as titration). This gives you, your device (and your jaw joint) time to get accustomed.
Which means you STOP SNORING!
And don’t permanently harm yourself. Yay!
They will take X-rays and put things right beforehand if necessary. If it doesn’t look like its a good idea, they’ll suggest:
If everything is OK, they’ll monitor the effect the MAD is having upon your teeth, gums, jaw joint and snoring.
If your jaw joint isn’t healthy before you start using an anti-snoring device then it may cause irreversible harm. (The exception is when a specialist sleep and jaw joint pain [Temporo-Mandibular Joint Dysfunction or TMD] dentist prescribes a device for BOTH issues.)
A sleep-trained dentist would know what to avoid and ensure you did not experience premature posterior contact (see call out box) that would damage your jaw-joint.
This gets a bit technical.
A common problem particular to ‘gumshields’ occurs when the device is adjusted forwards known as ‘protrusion’ (you might do this in an attempt to increase the effect – and stop the snoring noise). The upper and lower parts of the device may then come into contact on just your back teeth.
This acts like a ‘bit’ for a horse – it gives you something to chew on. It ‘gags’ open the bite (keeps your jaws more open than they should be) and this uneven bite places enormous load on your jaw joints.
It would be even worse for your jaw joint, if this was on one side only, and as you close your mouth, your jaw has to ‘rotate’ around this ‘premature contact’.
What the above means, is that your jaw has to move in unnatural ways.
And if you use the device in this position (because you’re trying to appease your partner) you may irreversibly damage your jaw joints.
How well your anti-snoring device fits, is known in dental terminology as ‘retention’.
But retention has two meanings in Dental Sleep Medicine (DSM is the term for MADs used to help with sleep-related breathing disorders, including snoring and OSA).
The first meaning is how well it keeps ‘hold’ of your teeth, or to put it another way, how well it ‘clips on’ or stays in place.
Most MAD designs rely upon its ability to ‘clip’ into place to then be able to hold your jaw forwards – and stop you snoring.
The second DSM interpretation of ‘retention’ relates to the MAD’s ability to hold open your airway, retain your jaw in a forward position, and prevent you from snoring.
So, the right amount of retention (or fit) is essential for it to work.
Due to the necessary choice of thermo-plastic (it softens and becomes adaptable to you, when heated in boiling water) material used in ‘boil and bite’ devices, getting and keeping the right degree of retention, for the long-term is nigh on impossible.
The material ‘wants’ to go back to its original shape as it cools down, which is technically due to both the elastic memory and elastic recovery of the material. There’s more about the material used in the Lifespan or ‘Cost per wear’ section below.
On the other hand, ‘Customised fit‘ devices are the ‘Boil-and-Bite’ gumshield type of MAD (and I know you know water boils at 100 deg. C!).
Without good retention or ‘clip’ to your teeth, gumshields will not stop you snoring.
The ability to adjust the forward position of your jaw (adjust the protrusion to prevent snoring) impacts upon both comfort and how well it works.
The optimum position is unique to you. It has to be just far enough forward to prevent you from snoring, yet not so far forward, it hurts your jaw joints.
Fixed devices (sometimes called ‘monobloc’ devices) take an arbitrary approach to the forward position of your lower jaw (they guess).
This primitive design (exhibited by both over-the-counter gumshields and some old tech custom-made ones) is likely to be less than ideal for comfort and of course effect.
Which leads neatly in to how anti-snoring devices work:
In a word: protrusion.
In the short video clip below, I explain how ‘protrusion’ (holding the jaw forward) opens the space behind your tongue (and what to avoid when choosing an anti-snoring device).
Click the video bottom-right to view the sound controls slider.
You should NOT need a chinstrap in addition to your anti-snoring device. If a chin straps is suggested then:
You need a different MAD.
If you’re trying to ensure you breathe through your nose and stop your mouth falling open, then read Chinstraps for snoring? Safe, Effective or Dangerous? [new window]. In my chin strap review, I examine if they have a role for snoring and obstructive sleep apnea (OSA).
If you can only breathe through your mouth and/or sometimes struggle to breathe through your nose, then consult your GP and seek an ENT assessment.
The important thing to understand about adjustable MADs relates to their range of movement, and:
The most modern custom-made adjustable MADs have between 8-10mm range of movement. If more is needed – you will most likely need a remake (more money).
To ensure your purchase of an anti-snoring device (MAD) is not a waste of money or a false-economy, you have to consider:
Amongst other things…
However, most are typically made from a type of denture acrylic (polymethylmethacrylate) or ‘PMMA’, and as such are stronger and less likely to absorb saliva than EVA materials. Some new variants are made from a type of ‘Nylon’ (polyamide) and are very strong in thin section (see Comfort and bulk above). This means they will last longer and therefore the ‘cost per wear’ may be reduced.
In the UK, it is also possible to obtain a custom-made anti-snoring device manufactured entirely from metal (known as ‘Chrome’ = Cobalt chrome wiki link: http://en.wikipedia.org/wiki/Cobalt-chrome ) While this type of manufacture may cost more (they are more time consuming to make) the material cross-section is extremely thin (fractions of a millimetre are possible) making the bulk in your mouth minimal (see comfort and bulk above). Additionally, the metal device does not absorb saliva or cleaning agents.
The downside is that any adjustment of ‘fit’ of metal devices may be problematic and over time the clasps (bits that wrap around your teeth to hold [retain – remember that?] the device in your mouth) may ‘relax’ and need adjusting.
The high-end devices using nylon or chrome are thinner and less bulky but are also difficult (if not impossible) to adjust. This does not mean to say its a problem, they just have to be perfectly made.
So, if its not – then it needs to be remade: Do not accept a poor fitting custom made anti-snoring device.
When using a mandibular advancement device (MAD) it is essential that your mouth does not fall open for effective snoring relief, which if permitted would make your airway narrower than it would be without a mandibular advancement device!
It should not be necessary to resort to a chin strap to control this. Yes, I’ve been over this point in point 7 Can I adjust the position of my anti snoring device above, but…
The lower jaw rotates backwards as it opens which further narrows your airway and makes snoring worse (or if you have sleep apnoea / apnea may increase the severity and duration of apnoeaic episodes).
If your jaw is protruded with a mandibular advancement device (MAD) and your jaw falls open your airway may be narrower than without using an MAD.
See the three X-ray diagrams below, to understand why vertical opening with an MAD should be avoided.
The red dots highlight how the airway increases / decreases with protrusion and vertical opening.
Images courtesy of Dr Ulrich Huebers DDS.
The diagram (below left) shows the size of the airway in your throat without a mandibular advancement device (MAD).
The diagram (below centre) shows the ideal situation. The mandibular advancement device advances the jaw and opens the airway in your throat.
The third diagram (below right) shows how the airway becomes narrower with both protrusion and vertical opening. Disaster.
An interincisal opening (the distance measured between the upper and lower front teeth) of more than 5 mm has been associated with lower patient adherence (long-term use), perhaps as a result of discomfort.6
Minimal vertical opening (as in just sufficient to permit the lower jaw to advance without the upper and lower teeth hitting each other) should routinely be considered ideal. More than this may be necessary in selected cases where:
However, opening beyond 5mm (measured between the incisors) is uncomfortable, inhibits lip closure and detrimentally impacts long-term use. A design principle for MADs is control of vertical opening (note my previous comment about not needing a chin strap).
Finally, consider your sleep position. Avoid sleeping on your back and ensure that your neck is inline with your body. Choose a supportive pillow. Learn more about positional therapy and anti-snore pillows.
It might seem obvious, but unless the MAD is worn, it cannot stop your snoring.
As such, it must be comfortable to use. Part of this comfort equation is the MAD not creating a ‘trapped’ sensation.
This may occur when the lower jaw is unable to move from side-to-side.
Finally, while it is perhaps a contentious area, if you routinely ‘brux’, then an anti-snoring device that does not permit side-to-side (lateral) movement may actually disrupt your sleep. One theory suggests that this is because your attempts to move are hindered.
The opposing theory suggests you will no longer brux when your apnea is resolved. The jury is out.
Ever had a filling or a crown? You may recall how you were very conscious of it.
You probably explored it with your tongue and it felt alien. Every anti-snoring device will feel huge in your mouth when you start to use it.
Consequently, less is more!
Less physical presence in your mouth, squashing your tongue, enhances your ability to initially accept it and keep using it – and stop snoring…
The concept behind an MAD is to advance the jaw, and in turn, move the tongue forwards and away from the back of your throat.
This increases your airway dimensions and improves tissue tone, which stops you snoring.
So, when an MAD is too bulky, it squashes your tongue. Which is self-defeating.
Technically, this may occur with ‘gumshields’ at the junction between two materials, typically with devices that have a hard-outer shell and a softer thermoplastic liner, or when they are crudely ‘adjusted’ with home equipment i.e. scissors!
Some primitive custom MADs are bulky and invade tongue space. Materials technology is continually improving, and thinner cross-section devices are now appearing on the market using laser sintered polyamide (a type of nylon).
While traditionally manufactured metal (known as ‘chrome’) devices are available. These may be expensive to make (as they are labour intensive) and may necessitate plastic and metal combined devices, which builds in failure points (because dissimilar materials exhibit different mechanical properties).
The placement of adjustment mechanisms in the tongue space is uncomfortable and counter-productive (see concept note above in introduction to this point). Some early custom MADs used orthodontic screw mechanisms in the palate or inside the lower jaw (lingually).
A sleep-trained dentist will guide you when you choose. To get informed for that conversation download our free, evidence-based How to Choose a Mouthpiece Guide.
Anything placed where your tongue can contact it, is a negative. Remember less is more, when it comes to MAD design.
Consult your dentist and the MAD manufacturer’s instructions on how to clean your MAD.
I would suggest that broadly speaking you should (every time you remove it in the morning) use a toothbrush and toothpaste on the device before/after cleaning your teeth.
Floss if you have the enthusiasm and discipline… and consider using a chlorhexidine mouthwash too.
Having worked in this industry for longer than I care to remember, I know that MADs must be:
Bacterial biofilm (a slimy film of infectious microbes) will form on the device.
It’s important to pay extra attention to your oral hygiene (and keep the MAD clean with a toothbrush immediately you remove it in the morning).
See a dental hygienist if you need assistance keeping on top of this. Its an investment.
If you are lucky enough to have a marble bathroom, make sure that the MAD cleaning fluid does NOT splash out (powder or granule type cleaning products are commonly a type of acid that permanently damages marble). Ideally, clean your MAD elsewhere! (Voice of experience! Customer reported the above to me when I ran Zacher Sleep Appliances).
There’s always a down-side!
Or in ‘English’:
“You don’t get nowt for nowt”
The most common initial side-effect from using anti-snoring devices is related to saliva.
Some people find they dribble while wearing the device during the first few weeks of use (use a towel on the pillow).
Others may find they have a dry mouth.
If this occurs, the correct advice is to speak with your dental clinician. It normally resolves itself but do not suffer in silence.
This is why even the most wonderful anti-snoring devices are NOT suitable for children – because they would act like an orthodontic device and move their teeth in uncontrolled ways (exceptionally an orthodontist may prescribe an anti-snoring device for certain children with particular needs).
However, as I have highlighted throughout this review all anti-snoring devices have side-effects.
A sleep-trained dentist would screen you for sleep apnoea, help you stop snoring and minimise (and if necessary correct) any side-effects. They also carry professional indemnity insurance and use prescription anti-snoring devices made to quality standards by registered dental technicians.
If you snore and self-help isn’t cutting it then don’t self-diagnose.
Instead, consult a sleep-trained pharmacist.

My final verdict is that while a ‘boil-and-bite’ gumshield may prevent snoring for a short while (if you fit the gadget) they are ultimately a false economy and won’t work for long (if at all).
Longer-term, if you were to persevere with a ‘gumshield’ for snoring, it would:
In conclusion, clinical research3 has established that ‘boil-and-bite’ gumshields are not valid as either a trial or treatment device.
