WonderSmile Invisible Aligners

Our invisible aligners are just that! They’re almost impossible to spot unless you look very closely. WonderSmile invisible aligners are orthodontist-designed and custom built specifically for your teeth, so that it is the perfect fit for you. The aligners steadily move and shift your teeth over time, giving you something to smile about!
Our clear aligners are prescribed by our orthodontics team and arrive as a complete set to your doorstep. Focusing only on the front 6 teeth of both upper and or lower arch, each set contains a series of individual aligners, designed to make minor adjustments over time. This procedure is carefully designed by our WonderSmile orthodontics team, who review each case. Each customer case is completely personalised and the average treatment plan is between 6-9 months.
We don’t discriminate! Our WonderSmile orthodontists will assess each customer on a case by case basis and will advise whether a customer is eligible for WonderSmile clear aligners.
For any customers who have had teeth removed, we recommend waiting at least 6 weeks after having any teeth removed. Customers who would like to begin earlier, should seek advice from their dentist beforehand.
Our aligners are made from BPA free plastic, which will not irritate your gums unlike traditional braces.
Your treatment will arrive in our signature blue box by tracked delivery so you can make sure someone is at home to receive your parcel.

Impression Kit FAQs

Our Impression Kit contains all the essential things you need to create dental impressions of your teeth.
Whether you book an appointment with us or order an impression kit, your aligner treatment will be the same. The only difference is if you order an impression kit, you won’t need to visit a WonderSmile clinic. It’s the option to choose if you want to get started from home.
Simply order your Impression Kit and we’ll deliver it straight to your door. Inside your kit there will be a guide with step by step instructions on how to make your impressions. Once you have completed your impressions, send all 4 moulds back to us using the pre-paid label provided in your kit.
Each mould needs to be on your teeth for at least 3 ½ minutes before removing it gently in a see-saw motion. It is important that you read the instructions a few times before starting your impressions so make sure that you allocate enough time before starting.
Start with the top arch and then move onto the bottom arch. Once you have completed your first set, take photos of the moulds and send them to us at review@wondersmile.com. Wait until we get back to you before starting your second set.
After you send us photos of your first set, we will review your moulds and let you know if you need to change anything for your second set.
Each tooth impression needs to be clean and visible. Make sure that the putty is fully mixed, the impression is a single print, the molars are captured and that the gumline is present.
The putty wasn’t mixed in properly, the impression was too shallow, the tray was dragged out of the mouth or the putty dried out before the impression was made.
We scan your moulds and send them off to our orthodontics team who will review your moulds and determine your eligibility. If successful, our orthodontics team will design your personalised treatment plan and we will send it to you via email.
If you are eligible for WonderSmile invisible aligners and proceed with undergoing treatment, we will deduct the cost of your kit from the total cost of your treatment.
Yes! If you aren’t eligible for invisible aligners, we will refund your money back.

NightClear FAQs

Compared to our All-Day aligners, our NightClear aligners only need to be worn at night, so you can straighten your teeth as you sleep. You won’t have to worry about taking your aligners off throughout the day when you eat or drink, and this option is even more discreet if you prefer to straighten your teeth only at home.
Absolutely! All of our invisible aligner options are Orthodontist-designed specifically to your needs. The end result will be the same. The only difference is the amount of aligner wear-time and treatment length.
NightClear invisible aligners are worn for 10 hours each night, whereas All-Day aligners need to be worn for 22-hours throughout the day.
The trade-off of wearing NightClear aligners for less time every day is that the duration of treatment is usually longer. With NightClear aligners, you can expect to see results in an average of 9 months versus an average of 6 months for All-Day aligners.
NightClear aligners are priced at £1,490 which is slightly more than All-Day (£1,450).
Nightclear aligners uses a thicker resin as part of manufacturing. This allows aligners to safely align teeth while the body is resting.
It's important that you choose carefully when selecting your treatment plan type. Our All-day and NightClear aligners can vary in treatment length, process and cost. This makes it difficult to change midway through without impacting your WonderSmile journey and possibly disrupting treatment. However, our team SmileCare Consultants, supported by our orthodontic and dental team, will be able to advise you on our aligner treatment options and answer any questions you have to ensure you make the right choice for you and your teeth. If you do have any issues, please contact our support team so we can discuss your options.
There will be some getting used to wearing aligners at the start of treatment, but this won’t take long and will feel comfortable in no time. The best part – you’ll be asleep for most of it whilst your teeth straighten and shift to give you the smile of your dreams!
The good news is you can get your teeth straightened at any age. At WonderSmile, we strive to ensure that you get the best care and the best results for your teeth alignment and our orthodontists take age into consideration when designing treatment plans. As we get older our teeth can move at a much faster rate, so we do have age guidelines for our NightClear aligners. If you would like to improve your smile and overall oral health with nighttime aligners, we encourage you to book a scan to discuss your options and eligibility with our scan specialists.

Treatment Procedure

All patient treatment plans are assessed, designed and reviewed by our qualified dental and orthodontics team, so you’re in safe hands!
That’s the beauty of our technology. Before you even start the treatment, you will receive a 3D simulation video of how your teeth will shift over time, at each stage. We like to keep things transparent and clear upfront.. pun intended. If you have any questions regarding your prescribed treatment plan, just call our Customer Care team at 0203 965 1800 or email jane@wondersmile.com.
Everyone is different, some will be shorter or longer than others. The average time is between 6 to 9 months. It just depends on the complexity of your correction and what our orthodontists prescribe to ensure safe and comfortable results.
Our orthodontist will assess your case and determine the optimum solution for you. If it turns out that you only need one arch, we’ll also reduce the price by £250.
To suit the different lifestyles of our patients, we like to give our patients the choice:

All Day Aligners - we recommend you wear for 20-22 hours per day, taking them out for eating and drinking.

Night Clear Aligners - we recommend you wear them for 8-10 hours whilst you sleep.
The 3D scan definitely does not! With our aligners, some customers may find some tightness in the first few days of a new aligner but that’s perfectly normal, that just shows the aligners are getting to work! It should ease off in a few days. In any case, our team are only a phone call away to help.
None! You only need to visit us to conduct your scan, after that, we review your progress remotely and can organise a visit if you need but that’s very rare! You can have your Saturday brunches back.
The best thing to do is wear your old aligner from the previous stage. We can get a replacement made for £25 but it’ll take time to produce and send to you. In most cases, customers can just pop in the previous set or even progress forward one stage earlier
Love your new smile? Want to keep it? Just like braces, we organise retainers made just for you, for £60. We recommend you replace your retainers every 6 months
Just sign into your online profile and it will show when you should be moving to the next stage. We’ll also send you reminders so there’s less chance you’ll forget
Our orthodontics team create your personal 3D treatment plan and have it sent directly to your email within 5 to 8 working days.
We'll have your complete set of aligners delivered to your door in 25 working days.
Your aligners are clearly numbered in individual packaging making it easier to identify which stage to wear. You can enter your start date in your online dashboard to see the next date for changing each stage.
WonderSmile is designed for mild to moderate teeth crowding. Some customers experience an improvement to their bite when teeth are moving, but this isn't what they are specifically designed for. Once our orthodontists design your treatment plan, you will be able to see the movement and what can be achieved.
We consider each case individually, please call our customer care team on 0203 965 1800 and a member of our team will be happy to discuss this with you.

Lifetime Guarantee

Your smile is guaranteed for life – we commit to providing additional treatment at no extra cost if your teeth ever shift out of alignment for the rest of your life.
We cover any undesired movement of your teeth once treatment has been completed, and you can demonstrate that your treatment plan and retainer use was followed as directed. If the conditions are satisfied, you can visit one of our clinics or we can send you an Impression Kit to assess the misalignment. A new treatment plan will be generated by our orthodontic team to help correct any issues. This guarantee covers only teeth originally involved in your WonderSmile treatment plan. If you are required to undergo any dental procedures, orthodontic treatment or have any external circumstances that may cause a change in your teeth position upon completion of your WonderSmile journey, this may void your lifetime guarantee. Permanent and bonded retainers will void the WonderSmile Lifetime Guarantee as this involves dental or orthodontic procedures that may impact teeth alignment.
Upon completion of your treatment, wearing retainers is required to keep your teeth in their new position for life. Teeth may shift out of place again if you stop wearing retainers. We recommend you wear your retainers full-time for 2 weeks after the completion of your clear aligner treatment. After that, retainers are required to be worn daily for 8hrs per day such as during your sleep. For hygiene and effectiveness, retainers must be replaced at least once every 6 months. Some customers prefer 3 retainers per year, every 4 months. To remain qualified for our Lifetime Guarantee, you must use retainers provided by WonderSmile. All purchases will be reflected in your WonderSmile account. 

Refund Policy

If within the first 30 days of receiving your aligners you are not happy for any reason, contact us first. From there we can discuss your options. To be eligible for a refund, you must inform us before you return your unused aligners. Production fees may apply.

The 30-day period begins the day your aligner treatment package is delivered to you. Please note you will be responsible for any return shipping charges.

Once we receive your unused custom-made aligner treatment, we will provide you a refund.

If you are past the initial 30-day period, and are still not satisfied with your treatment, WonderSmile will work with you to provide refinements to your treatment so you can achieve the smile you want. All cases are unique and your teeth can continue to shift and change gradually throughout. Only once treatment is complete can we fully determine if a desired outcome has been met, and often a simple refinement is all that's required to continue your journey to straighter teeth.
Contact us and we will work with you to see what the issue is. If required, we will provide replacements at no extra cost. You will need to inform us immediately as soon as you identify any faults with the product, and you may be asked to provide photos for quality control and review.
Once we have received your unused aligner package, our team will inspect and process the refund if applicable. Refunds typically take 10-15 business days to process.
