Home clear aligners are incredibly convenient, so it’s no surprise they’ve garnered a lot of popularity in recent years. After all, who doesn’t want to straighten their smile with easy-to-use aligners that don’t require regular doctor’s visits?
If you’ve done any research into the UK’s clear aligner scene, you’ve probably seen WonderSmile. And maybe you’ve wondered if these are the right clear aligners for you. With all the aligners on the market, it can be hard to sift through all the choices.
In this guide, we’ll cover everything there is to know about WonderSmile, including how their treatment works, how long treatment lasts, how customers review them, and more. By the end, you’ll know for sure whether or not WonderSmile is the aligner for you.
How Does WonderSmile Work?
Using WonderSmile is relatively simple, particularly since they offer two different ways to kickstart your treatment. You can schedule a free appointment at one of their dental clinics, and a technician will take images of your teeth. This convenient startup option puts all the responsibility on WonderSmile; all you have to do is show up and say “ah”.
If you don’t live near a WonderSmile clinic, you can order an at-home impression kit, instead. This process can be a little trickier than the scan, but WonderSmile will do everything they can to help you through it remotely.
Using your molds or scans, WonderSmile’s team designs and ships aligners to you. For most people, treatment lasts about 6 months (9 months for nighttime treatments). Here’s a fly-by of what to expect when using WonderSmile:
- Step 1: Schedule an appointment at your local WonderSmile clinic to have scans taken of your teeth. If you don’t live near one of WonderSmile’s locations (or just prefer a DIY approach), you’ll have to order an impression kit, create molds of your teeth, and send them back to WonderSmile. Don’t worry, shipping is covered with a prepaid shipping label.
- Step 2: WonderSmile analyzes your molds or scans and develops a treatment plan that’s unique to you.
- Step 3: Pay for your treatment all in one go, or sign up for one of WonderSmile’s monthly payment plans.
- Step 4: WonderSmile ships your aligners directly to you. You wear each set as prescribed and gradually make your way to a straighter smile.
That’s pretty much all there is to it! WonderSmile has a pretty straightforward process from start to finish.
What Sets WonderSmile Apart?
WonderSmile offers teledentistry, which is a pretty new service. In fact, the oldest company in the industry launched less than a decade ago in 2014. WonderSmile only recently joined the UK clear aligner scene, but they have a great reputation and serious international reach. Currently, they serve customers in Australia (where they started), New Zealand, Singapore, and here in the UK.
While WonderSmile isn’t our favorite service (that honor goes to Straight Teeth Direct), there is a lot to love about them. Thanks to their substantial network and proven reputation, they can offer several perks that some competitors can’t. Nighttime treatment, single-arch treatment, and 3D scans instead of messy impressions are just a few examples.
All told, WonderSmile is a great method for anyone looking to straighten their teeth without visiting the dentist’s office.
Product Quality
There are a few similarities across all clear aligners providers. For example, all clear aligners are made from BPA-free plastic. However, there are other ways in which the design of aligners varies from provider to provider. Let’s see how WonderSmile designs theirs, specifically.
Materials
WonderSmile doesn’t publicly share who manufactures their clear aligners, so we can’t officially speak to the overall quality of the product itself. One thing we really appreciate about WonderSmile’s product though is that their nighttime-only NightClear aligners are made out of a thicker and more durable resin than their all-day aligners; so you can be sure they’ll withstand any teeth grinding you throw at them.
Appearance
Many people are drawn to clear aligners because of their low profile. Especially when compared with attention-grabbing braces, clear aligners are a great way to have your treatment go under the radar. But not all clear aligners look the same.
Clear aligners are mainly cut in one of two ways: straight across or scalloped to mimic the gumline. Straight-cut aligners can exert more force since they overlap with the gums, but that same overlap makes them a bit more noticeable. WonderSmile’s aligners are straight cut, so you can be sure your aligners are as effective as possible.
This might sound a little counterintuitive, but crystal clear-looking aligners aren’t always the most discreet. Some providers (like Invisalign and Smile Direct) make their aligners from slightly frosted plastic, which blends in better with the porous surface of your teeth. WonderSmile makes their aligners from clear, shiny plastic, so their gleam might be a bit more noticeable than competitors who go the frosted route.
That being said, appearance is subjective, and plenty of customers like the added shine that WonderSmile aligners give their smile. All that’s important is you find a clear aligner that works for you.
Treatment Oversight
With WonderSmile your treatment occurs remotely, which means your oversight will too. During months 1, 3, 6, and 12 of your treatment you’ll upload progress photos of your teeth to the WonderSmile app for review. This helps their team keep an eye on your treatment to ensure everything is going to plan.
On average, you can expect all-day treatment to wrap up in 6 months, and nighttime only NightClear treatment to finish in 9 months. In stark contrast, traditional options like braces and Invisalign can take 18-24 months to complete. Not only do those treatments take much more time, they also fill up your schedule with appointments. Every 4-8 weeks of treatment you’ll need to attend an in-person appointment. Accommodating a dozen or so appointments is no small feat for a busy adult.
WonderSmile’s simple remote check-ins and short treatment lengths can be a much more manageable way to incorporate treatment into a packed schedule.
There are plenty of ways to get in touch with WonderSmile outside of your photo check-ins, too. They offer phone, email, and social media support. We’ve found that phone support is the best way to get a quick response; social media can take a bit longer. Regardless of how you get in touch with WonderSmile, you can expect excellent, personalized attention.
Bang For Your Buck
WonderSmile is far cheaper than traditional options like braces and Invisalign; but how much savings are we actually talking about? Let’s dig into the nitty-gritty details of how much you can expect to spend when you choose WonderSmile.
Startup Costs
There are two ways you can kickstart your WonderSmile treatment: an in-person scan, or an at-home impression kit. The scans are quick, convenient, and best of all; they’re free. If WonderSmile’s scanning locations aren’t convenient for you, then you’ll need to opt for their £59 impression kit.
If WonderSmile determines you aren’t a good candidate for treatment, they’ll refund you the cost; so it’s a pretty low risk option. Additionally, if you decide to go ahead and purchase aligners, the cost of your impression kit will be deducted from the total of your aligner package; so in a way this step is free.
Aligner Kit
Your aligner package comes with everything you need to transform your smile. The all-day aligner package (22+ hours of daily wear) costs £2,250, and their NightClear treatment (10+ hours of daily wear) costs £2,290. We appreciate that WonderSmile barely charges more for their nighttime only treatment option, even though these aligners are made from more durable materials.
It doesn’t happen often, but some rare cases may be approved for single arch treatment; which would take £250 off the cost of your aligners.
Potential Add-Ons
If you want to whiten your smile while you align it, you can purchase WonderSmile’s whitening kit for £79. Some providers include a bottle of whitening for free in their aligner packages, but WonderSmile keeps their package pretty simple.
Financing
Don’t have ~£2,000 burning a hole in your pocket? No problem, WonderSmile offers in-house financing called WonderPay. The best part? The financing is interest-free, so you’ll pay the same amount regardless of whether you pay in full, or spread the payment out over time.
All you need to do is make a 10% downpayment, then your subsequent monthly payments will be determined by a credit check.
Post-Treatment Costs
The best way to preserve your new smile post-treatment is to wear aftercare retainers. Some providers include your first set for free in your treatment bundle, but with WonderSmile you’ll need to purchase your retainers separately for £60. These retainers are durable, but they don’t last forever. You’ll need to replace them every 6 months or so.
Which treatment plan is right for me?
At-home clear aligners are way more convenient than traditional options like braces, but these treatments still require some maintenance. You’ll need to remove them at mealtimes, then brush your teeth and clean your aligners before replacing them. If your days are already stuffed to the gills, even minor upkeep like this can be difficult to accommodate.
With WonderSmile’s NightClear treatment, you won’t have to think about your treatment until the evening. Just carry on with your day like normal, then pop in your aligners a few hours before you go to sleep and dream your way to a new smile.
Once WonderSmile reviews your impressions, they can let you know which treatment options are available to you. Though clear aligners can treat mild to moderate cases, nighttime only options are best suited for conditions on the milder side. So if you’ve got a packed schedule and some minor crowding/spacing, then nighttime only treatment may be a great fit for you!
Customer Experience
The look and price of your aligners are important, but so is how you’re treated throughout the process. Let’s take a look at what you can expect when you choose WonderSmile.
Reviews
If you want to know how customers are treated by a company, it’s a good idea to go straight to the source! Online reviews are the new word of mouth when it comes to assessing services and products. WonderSmile is still pretty new, so there aren’t thousands upon thousands of reviews, but there are enough to get a good idea of what this system is all about. So, what are other customers saying about WonderSmile?
It’s important to account for both the good and the bad. So, here are a few of the things customers like about WonderSmile:
- Very knowledgeable, friendly customer service.
- Treatment discomfort was minimal.
- Getting adjustments to treatment is relatively simple.
- 3D scans make start-up easy.
But there are a few drawbacks, too:
- Retainers sometimes break, which can be a hassle to replace.
- Mix-ups can occur with initial impression kits & account setup.
All things considered, WonderSmile has a positive online reputation; negative reviews seem to be pretty few and far between. Unfortunately, shipping is never perfect; things can get tricky if your aligners get lost in the mail. Broken retainers aren’t the norm, but it happens. By and large, we’ll say that WonderSmile’s positives outweigh their negatives.
Comfort
Let’s be clear: teeth alignment is never going to be a completely painless process. This is true of all orthodontia—even traditional options like braces and Invisalign come with their fair share of aches and pains.
That being said, it’s usually just a bit of soreness the first few days after switching to a new aligner set, since the next set of aligners are always snugger than the last. Switching out your aligners at night can help you sleep through most of the adjustment period.
WonderSmile’s reviews are full of customers describing their relatively pain-free experiences, and assuring other users that any discomfort they’re feeling will subside.
Guarantees
Refunds are unusual in the clear aligner industry since these products are custom-made. Quite unusually, WonderSmile offers a refund within the first 30 days of your aligners arriving on your doorstep. If you have second thoughts within that time frame, reach out to the WonderSmile team first to discuss your options before you return your unused aligners in the mail.
WonderSmile also offers a guarantee on the longevity of your smile. If your teeth shift in the first year after your treatment concludes; WonderSmile will provide the aligners you need to get your smile back to its former glory. To hold up your end of the bargain, be sure to stay up on wearing and replacing your post-treatment retainers; and WonderSmile will handle the rest.
What if I break an aligner?
WonderSmile can send you a replacement aligner for £25, but in general, they recommend you just wear your previous or next aligner until it’s time to make the next switch. That way, your treatment won’t be delayed while you wait for the new set to be manufactured.
Refinement Policy
If you reach the end of your original treatment plan and your teeth need a bit more movement, you’ll need refinements (extra aligners). Some companies charge extra for refinements, but not WonderSmile. As long as you’ve stayed on top of your aligner wear and are up to date with your photo check-ins, your refinements will be covered by WonderSmile.
Teeth can be a little stubborn sometimes, so a generous refinement policy like WonderSmile’s can give you peace of mind throughout your treatment that you won’t need to fork over more money to get the results you want.

Best WonderSmile Alternatives
WonderSmile has plenty to offer its customers, but that doesn’t mean they’re the right fit for everyone. Let’s take a look at some alternatives.
Straight Teeth Direct
Straight Teeth Direct is our all-around favorite UK clear aligner provider. Their boutique beginnings as a traditional orthodontic practice come through in their thorough customer service and their comprehensive treatment guarantees. They balance affordable pricing with high-quality offerings; they’re our #1 ranked provider for a reason!
Straight My Teeth
If affordability is a top priority for you in your treatment, then look no further than Straight My Teeth. They boast the lowest prices in the industry, but they don’t sacrifice quality to cut costs. With frequent treatment oversight, excellent customer service, and the industry’s lowest pricing, Straight My Teeth has more than earned its #2 ranking.
PlusDent
PlusDent organizes its treatment into 3 tiers based on your condition’s severity: light, medium, or complex. Each treatment tier offers plenty of financing options, so you can find the option that best fits your needs. Uniquely, PlusDent doesn’t offer an impression kit; you can only begin treatment by visiting their clinics for a scan. These appointments are convenient and quick, but this does limit who can choose PlusDent for treatment; due to location.
Should You Use WonderSmile?
WonderSmile has plenty of positives, but are they right for you?
✔ When to use WonderSmile:
WonderSmile is a great option if you want to balance treatment flexibility with affordability. They aren’t the fastest or cheapest in the UK, but they strike a nice spot in the middle for mild to moderate cases of misalignment.
✖ When NOT to use WonderSmile:
If you have a bite issue like underbite or a severe case of crowding or spacing, then you’re probably not a good candidate for any home alignment system—WonderSmile or otherwise. But if you’re not sold on WonderSmile, check out Straight My Teeth for the industry’s lowest pricing; or Straight Teeth Direct, if you’re curious about our #1, ranked UK clear aligner provider.
Final Verdict
All in all, WonderSmile is a good, respectable option. But they’re not our top choice; we rank them at #4 among UK at-home aligner companies. It’s not that they have big problems to work out or anything, we just find other providers a little more impressive.
Frequently Asked Questions
Does clear aligner treatment even work?
Clear aligner treatment works, no question. But it only works when you wear your aligners as prescribed. If you fail to wear them like you should, your teeth won’t shift into straighter positions; they might even become more crooked than they were in the beginning. Likewise, your treatment results will only last provided you wear your retainers as prescribed.
Is clear aligner treatment safe?
You bet! Clear aligners are a perfectly safe way to straighten your teeth as long as you adhere to your prescribed treatment. It’s when people don’t wear their aligners like they should that they run into trouble; if you wear them for too short a time each day, your teeth don’t get the chance to heal enough between aligner switches, which hurts your teeth in the long-term. Similarly, if you don’t clean the aligners faithfully, remove them when you eat, and brush your teeth before reinserting them, you run the risk of tooth decay (or at the very least, some questionable bad breath).
How is WonderSmile different from Invisalign?
On the surface, WonderSmile and Invisalign seem identical to each other. After all, their aligners look very similar: clear tooth-shaped trays. And both treatment regimens will get you the smile of your dreams.
Invisalign, however, is different from WonderSmile because of one key distinction: Invisalign is an in-office treatment, and WonderSmile is administered remotely. Invisalign requires direct, in-person oversight to be successful, and in return, that lets Invisalign treat the full array of cases, from mild to extremely severe. WonderSmile can only treat mild to moderate cases because severe cases require in-person oversight.
Does WonderSmile offer any discounts?
WonderSmile’s most common discount is their referral program. But you can also subscribe to WonderSmile’s email list. If you do, you’ll be one of the the first to know about their occasional sales of £100-£200 off your aligners.
Is WonderSmile the fastest home aligner?
There are faster treatment options out there, but they aren’t currently available on the UK market. All of the UK aligner companies—WonderSmile included—take about 6 months to correct a smile. There will be some discrepancy from one company to the next, but all of our top picks have an average treatment speed of 6 months.
Is WonderSmile the cheapest home aligner?
WonderSmile is on the higher end of the price spectrum for home clear aligners, so they definitely aren’t the most affordable one. If you’re looking for the cheapest one (that doesn’t also sacrifice quality), then you should look into Straight My Teeth. Their sticker price is just £999.
What about nighttime treatment?
Some customers find that it’s more convenient to do nighttime treatment, or aligners that you only wear for about 10 hours per day. Nighttime aligners are available with some online clear aligner companies, and WonderSmile is one of them. We also love that they only charge an extra £40 for nighttime treatment, too.
How do I know when to switch aligners?
WonderSmile doesn’t leave you hanging when it comes to switching aligners. In fact, they give two methods to keep on track. First, your online profile will tell you when you need to switch. And WonderSmile will also send you reminders to help you stay on track.
Can I drink coffee while using WonderSmile?
Technically you can, but you shouldn’t. For starters, hot drinks can warp your aligners, making them ineffective. Plus, dark foods and beverages can permanently stain your aligners. You should remove your aligners every time you eat or drink anything besides cool water.
Can I smoke while using WonderSmile?
It’s physically possible, but you shouldn’t. Any dentist will tell you that smoking will stain your teeth and can deteriorate your overall oral health. But when it comes to wearing your aligners, smoking with aligners on can stain them.
Is there an age requirement for WonderSmile?
WonderSmile will treat anyone ages 12 and up. Anyone under age 18 will need parental consent prior to treatment.
Does WonderSmile offer whitening?
WonderSmile sells a whitening kit separately for £79. Some providers include a bottle of whitening for free in your treatment bundle, but with WonderSmile you’ll need to buy it separately.
What’s up with retainers?
When you finish your treatment, WonderSmile will send you trays that look a lot like your aligners. And their purpose is to hold your teeth in their newly-perfected positions.
After treatment, your teeth have a natural tendency to relapse, or shift back to their original positions. Even years afterwards, teeth still shift; it’s a natural part of aging. Wearing retainers—usually full-time for a few weeks and then overnight indefinitely—prevents that from happening, preserving your investment.
How often should I replace my retainers?
Retainers are designed to be more durable than aligners, but they still don’t last forever. WonderSmile recommends that you replace your retainers every six months. They cost £60 a pair, so it’s not hard to maintain that replacement schedule.
