The SleepPro Custom S2 is our original custom-made mandibular advancement device (MAD) — a laboratory-crafted mouthpiece designed to reduce snoring and, where a clinician has assessed it as appropriate, to help manage mild-to-moderate obstructive sleep apnoea (OSA). Each Custom S2 is made individually from a professional impression of your teeth, giving a slim, secure and precise fit that's very hard to achieve with generic boil-and-bite devices.
By gently holding your lower jaw slightly forward during sleep, the Custom S2 helps keep your airway open — so you can breathe more freely, snore less and sleep more soundly.
Why choose it?
Why choose Custom S2?
Individually made in a UK dental lab. Your Custom S2 is crafted from a professional impression of your own teeth, so it follows your dental profile closely and stays securely in place all night instead of working loose.
Professional-grade quality, without the dental-chair price. You get a lab-made, custom MAD for a fraction of the cost of a device made privately at a dental practice — making a properly fitted appliance more accessible without compromising on quality.
Comfortable, low-bulk design. Because it's tailored to you, the S2 can be made slimmer and smoother than many over-the-counter devices, so it feels more natural once you've acclimatised — even if you sleep on your side.
The natural step up from "boil and bite." If you've tried a basic self-mould MAD and want better fit, comfort and durability, the Custom S2 is the upgrade. For anyone wanting a more personalised device, the SleepPro Custom range (S2 and AM) is the better choice.
Made in Britain by Meditas. SleepPro appliances are manufactured and supplied in the UK by Meditas Ltd, a company specialising in sleep-related oral appliances and night guards, with many years' experience supplying clinics and patients worldwide.
Evaluated in independent, published clinical research. The SleepPro 2 — the device behind the Custom S2 — was one of the mandibular advancement devices assessed in TOMADO, an independent NIHR-funded randomised controlled trial published in Thorax (2014). The trial found mandibular advancement devices to be clinically effective and cost-effective in mild-to-moderate obstructive sleep apnoea, with the semi-bespoke SleepPro 2 identified as the appropriate first-choice device for most patients.
Who is it for?
Who is SleepPro Custom S2 for?
Custom S2 is intended for:
Adults who snore during sleep
People diagnosed with mild–moderate obstructive sleep apnoea who have been advised that a mandibular advancement device is suitable for them
Users of basic “boil-and-bite” MADs who want a more effective, comfortable, longer-lasting, custom-made device
It is not a substitute for CPAP in more severe OSA unless your sleep or respiratory specialist specifically recommends this. If you snore loudly, stop breathing at night, or feel very sleepy during the day, you should seek medical assessment before relying on any oral device.

The evidence behind SleepPro
Most anti-snoring devices ask you to take their word for it. SleepPro doesn't have to.
SleepPro mandibular advancement devices were among those assessed in TOMADO — the Trial of Oral Mandibular Advancement Devices for Obstructive sleep apnoea-hypopnoea — an independent randomised controlled trial funded by the UK's National Institute for Health Research (NIHR) and published in Thorax in 2014.
The trial compared three mandibular advancement devices against no treatment in 90 adults with mild-to-moderate obstructive sleep apnoea-hypopnoea. Two of the three were SleepPro devices made by Meditas Ltd: the self-moulded SleepPro 1 and the semi-bespoke SleepPro 2 — the device behind today's Custom S2.
Its published conclusions were clear: mandibular advancement devices are clinically effective and cost-effective in mild-to-moderate obstructive sleep apnoea, and a semi-bespoke device — the SleepPro 2 — is the appropriate first choice for most patients in the short term. The trial also found that a well-fitted, individually made device was better tolerated than a basic self-mould, which in turn helped people keep using it.
If you think you may have obstructive sleep apnoea, it should be diagnosed and managed with a clinician — the right device, and the right jaw position, are best decided as part of that care. But if you're looking for an anti-snoring appliance built on the same approach that stood up to independent clinical scrutiny, that's exactly what the SleepPro Custom range is.

A custom MAD manufactured by Meditas is also the device used in the current PAPMAT study at Royal Papworth Hospital, which is investigating whether adding a custom MAD to CPAP can help certain higher-pressure patients tolerate treatment better. PAPMAT is an NIHR-supported, non-commercial NHS trial.
Together, these and other studies support the use of properly designed mandibular advancement devices as an evidence-based option for snoring, and for some people with mild–moderate OSA.

Why do I have to pay to send my impression back? Can't you offer prepaid return?
Two very good questions we get asked a lot and worth spending time on providing a detailed explanation. We are focused on providing a quality product, exceptional customer service at a sensible price. In the early days we offered the full package of prepaid return stickers. Just pop the impression in the bag and drop it in the post box! Well, that was a bit of a mistake, as many customers did just that. Put the impression in the bag, put the sticker in and dropped it in the post box. Much to the detriment of the impressions! Many arrived damaged beyond use so we had to reissue a new kit for the customer to retake the impression. For those in a hurry, that was not acceptable! So, we amended instructions to ensure the impressions were well wrapped before posting! The prepaid return service (Royal Mail Service) had specific parameters for weight and size, whilst light in weight, customers started to send in packages way to big, plenty of padding but over the size limitation for the prepaid service, so we were fined for every item over the limit. Which seemed to be most of them. Raising the size limit to the next band of pre-paid service made it too expensive! Whilst we used a first class pre-paid service the actual delivery time to our office ran from 5-10 days! Not acceptable to many customers and justifiably so, packets arriving with us when the item should have been made and delivered back to the customer in the same time scale. Phone calls a plenty! “Where’s my order I sent it first class using your label” Delayed by having too much padding added up to 5 days, delays from the poor postal service added 5-10 days it was not a sustainable situation! Add to this the ever increasing postal rates and a declining service we had to find a solution! Couriers? Way to expensive and equally if not worse at pickups or special arrangements!
So, after months if not years of trial and error, we decided to put the responsibility and expense of sending the impressions back here onto the customer. What a difference!
With customers now engaged in the process of shipping the impressions back, packages now arrived well packed without having to give instructions.
Postage fees applied correctly, no excess fees to pay
Express items sent without us having to make special arrangements.
Still no answer for the lost or delayed packages, but with customers engaged in the shipping process there is more understanding when things do go wrong in the postal system.
So while it may seem to some it’s a “penny pinching scam” it is in fact cheaper for the customer, more efficient and allows us to deliver a quality product and service

We ship SleepPro products from our UK laboratory. Delivery options and costs are shown at checkout.
For orders delivered outside the UK, your local customs authority or delivery company may charge import VAT, customs duty or handling fees before delivery. These charges are set by your country and are the customer’s responsibility.
EU customers: SleepPro products are also available through our European distributor at SleepPro.eu. If you are based in the EU, ordering from our EU distributor may be a simpler option, especially if you prefer local EU service and delivery.
Custom-made products: If your product is made from your dental impressions, we first send you an impression kit. After taking your impressions, you will need to pay the postage to send them back to our UK laboratory, unless stated otherwise. This is different from off-the-shelf products, which do not require impressions to be returned.
For international impression returns, please complete any required customs declaration and describe the contents as “dental impressions / impression material”. The declared value should reflect the replacement value of the impression materials only, not the value of the finished custom device.
Risk Assessment
Making your own dental impressions is straight forward but can has some risks which you should be aware of before deciding
Allergy. We use vinyl polysiloxane. Vinylpolysiloxane (VPS) is a type of silicone-based impression material commonly used in dentistry. It is a popular choice for making accurate dental impressions due to its high dimensional stability, tear strength, and accuracy. VPS is available in a variety of viscosities, allowing dental practitioners to choose the appropriate consistency based on the specific application. It is used in a variety of dental procedures, including crowns, bridges, and dentures. VPS has largely replaced traditional impression materials like alginate due to its superior accuracy and ease of use.
Damage to teeth, crowns, veneers, inlays, onlays, implants, crowns or other oral prosthesis. So long as your teeth are in good health, your crowns etc are fitting well and are not loose or leaking the risk of damage is minimal. But should you be concerned please check with your dentist first before considering a purchase or proceeding with any impression process. Ultimately it is your choice and we do not accept responsibility for any damage caused using our impression system.
Stuck impression. The impression material used is soft and "fluid" it is designed to flow around and between teeth to provide an accurate impression. If you have very "gappy" teeth or receding gums this can create more undercuts and greater surface area of tooth. Whilst the impression material does not have any adhesive quality, it can feel "stuck" to the teeth when trying to remove it. It is best to remove it by first breaking the suction on one side, pulling the impression off the molar area first usually works best. Once the impression starts to move it should slowly release all the way around. In the rare circumstances you are unable to break the suction a call to 111 will be necessary to find a duty dentist who would be able to assist. This is however exceptionally rare occurrence, but must be mentioned as a potential risk.
Bleeding after impression removal. If taking blood thinning medication, please be aware that when removing the impression it is possible to scratch or puncture the gum with a misplaced fingernail! Care should be taken if you are know to bleed easily.
If you experience bleeding gums after taking a dental impression, it is important to take it seriously. Bleeding gums can be a sign of inflammation, infection or trauma to the gums. Ignoring it can lead to serious dental problems such as gum disease, which can eventually lead to tooth loss.
To take action, first, consult your dental professional. They may recommend a follow-up appointment to assess the situation and provide you with an appropriate treatment plan. In the meantime, you can improve your oral health by gently brushing twice a day, flossing once a day, and using an antiseptic mouthwash. Be sure to avoid acidic or sugary foods and drinks that can irritate your gums. Finally, stay hydrated and get enough sleep to help your body heal. Remember, early detection and treatment can prevent serious dental problems down the line.

Long-Term Dental Care
Long-Term Dental Care & Morning Jaw Exercises
Mandibular advancement devices work by gently holding the lower jaw forward during sleep. This can be very effective for suitable users, but long-term use should be monitored as part of your normal dental care.
Why dental check-ups matter
Over time, any mandibular advancement device may affect how your teeth meet when you bite. In some users, this can include small changes in tooth position, bite contact, or jaw comfort.
Regular dental check-ups help ensure that:
Your teeth and gums remain healthy
Any bite changes are noticed early
The device continues to fit comfortably
Pressure points, looseness, or wear can be dealt with promptly
If you have gum disease, loose teeth, untreated decay, crowns, bridges, implants, jaw joint problems, or ongoing dental pain, please speak to your dentist before using a mandibular advancement device.
Morning jaw exercises
After wearing the device overnight, your jaw may temporarily feel slightly forward or your bite may feel different. Simple morning jaw movements can help your jaw return to its usual resting position.
After removing the device, gently:
Open and close your mouth several times
Move your jaw from side to side
Bite together lightly to re-establish your normal bite
Follow any specific exercises or advice given by your dentist
Some users may also be advised by their dentist to use a morning repositioning splint.
Important note
A mandibular advancement device is not intended to replace professional dental or medical advice. For long-term use, we recommend routine dental check-ups so your dentist can monitor your teeth, gums, bite, and jaw comfort.
I chose the Custom Pro because it mentioned there was no need to boil & fit, however the first step on the instructions is to boil & fit the temporary mould!
I tried to fit the temporary mould but gagged every time. I emailed help@sleeppro.com on 27/11/24 for advice and have never received a response.

I found it very uncomfortable. It really hurts my front teeth. I knew what I was getting. Yet it kept waking me, as my mouth is so restricted. I tried it for two weeks. I just don’t get on with it, well. Shame. As it was quite expensive. No bad reflect on the product or company. Just not for me.

This is my second purchase after deciding to advance the lower jaw following over a year’s use.
Literally changed my life. I’ve snored most of my life as I have a deep overbite. Going on holiday and sharing a room with anyone has always been a nightmare, and a strain on relationships!
I’ve used over the counter night guards for years to get by, but they were uncomfortable and placed all the weight of my jaw on my front teeth.
Since buying my Sleep Pro Custom AM I now have a comfortable , silent sleep. I wake up refreshed and my partner no longer has to either wear earplugs or sleep in the spare room. We can now save for our dream Campervan!
Literally life changing. Fantastic customer service too as my first guard had to be remade as my over bite is so severe.
Thank you, thank you , thank you!!!
When the first set fit loosely i contacted customer service. They were very helpful and immediately began making a new mold that fit better, no fight at all, just an efficient solution.

I’ve used a Sleep Pro mouth guard for years to stop my snoring. Yes: actually stop it, not just reduce it!
When I made a mess of making an impression of my teeth, the customer service was second-to-none In using previous impressions. The mouthpiece I now have is brilliant. I can’t recommend Sleep Pro highly enough. I never thought something so simple could make such a difference.
