Our Process

24 Hour Support Throughout Your Journey

With our team of on-call dentists available 24/7, you’re never alone on your journey. Whether you have technical questions, concerns about treatment, or just your monthly virtual checkup, we’re here for you. 


A mould or impression, is a special putty material that you place in a tray and push over your teeth to get a snapshot of your teeth, their position and all the small details. We scan this in our lab to recreate an accurate 3D image of your teeth and then plan all the precise movements to get your teeth to the perfect alignment.

Taking impressions with our home impression kit is designed to be straightforward and user-friendly. We provide clear instructions and support to ensure you can easily and accurately create the mould of your teeth from the comfort of your own home.

You can purchase our impression kit directly from our website. We offer a convenient online ordering process to get you started on your journey to a better smile.

If you encounter any issues or make a mistake while taking your impressions, don’t worry. We have a support team available to assist you. Simply reach out to us, and we’ll guide you through the process to ensure your impressions are done correctly. We also provide two sets of putty and impression trays with all kits. If you are not sure, please simply send a photo of your impressions on the website livechat so we can make sure they impressions are good, to reassure you.

Yes, in every impression kit there is a medical/dental history form and disclaimer, as well as a treatment consent form (also know as an informed consent form). These forms give us important information we need to know before making your aligners and also give you all the important information you need to know before going ahead with aligner treatment.

Once you’ve completed your impressions, you can easily return the kit to us using the prepaid shipping label provided in the kit. Simply package it securely and drop it off at your nearest post office. As we provide a pre-paid label, you don’t have to pay for, or do anything else, just drop it off.

Does a registered dentist or orthodontist review my case?

Yes, your case is carefully reviewed by a registered dentist or orthodontist affiliated with OvernightSmile. We have a network of international dentists and orthodontists. They will assess your impressions and create a treatment plan tailored to your specific needs, ensuring you receive the best possible care.

Yes! Our treatment plan that we provide free for anyone who has taken an impression with our kit is a 3D before and after of your teeth so you can see exactly what is changing and how your teeth will move into their perfect position, before you purchase our aligners.

Normally for simple to moderate cases 3-6 months but this can vary. It also depends on how good you are at consistently wearing the aligners. When we design your treatment plan, the amount of movement needed will tell us how long your plan will be and this will be on the treatment plan you receive, so you will know before you decide to go ahead/pay for treatment

It’s possible and we will give recommendations but in general we always recommend you move both upper and lower so they fit together well in your bite when your treatment is finished. *The price for upper only or lower only is no different to upper and lower.

Your aligners will come with the following to help you out during treatment :

Aligner Remover : A small plastic hook to help you take your aligners off. A lot of people do not need this but if you have long nails this can help you to prevent any damage to your nails.

Chewies : Chewies are small rubbery tubes that you can chew and bite on just to help you push the aligners tightly over your teeth.

We advise you to wear your aligners between 14-22 hours a day. Our technology allows for considerable movement with only 14 hours wear – however, the longer you wear the the aligners the quicker you will achieve your desired result.

Our aligners should never be worn for less than 14 days per aligner. Your teeth need this time to move successfully and safely. 

Yes, you must keep all your aligners until your treatment is done and you have your retainers. If one gets lost or damaged, or if you have any issues with fit, we may ask you to go back to a previous set. Just put used aligners back in their original packaging for safekeeping.

You should take your aligners out to eat and to brush your teeth. After you eat, you can simply rinse your mouth, remove any food debris and put them back in, however some people like to brush their teeth before they put the aligners back in (this is not absolutely necessary but you must do what fits with your lifestyle).

You can drink with the aligners in and our aligners are clinically tested to be very stain resistant but you can also remove them for hot and dark drinks if you feel more comfortable.

After wearing new aligners, some people feel tooth soreness for a few days. It’s normal and shows your aligners are working. It usually goes away after a few days.

As you finish each set of aligners, you should notice that your teeth align perfectly with the aligners, leaving little to no gaps. This means you’re making progress! However, if you reach the end of an aligner set and still notice a lot of misalignment between the aligners and your teeth’s actual positions, please contact our support team via the website livechat.

We strongly recommend against it! Your aligners are carefully calibrated to move your teeth at the ideal pace, neither too slow nor too fast. If you ever experience issues with the fit of your aligners at any stage, please don’t hesitate to get in touch with our team through the live chat on our website.

If you lose or break an aligner, contact our customer support team immediately. We will guide you based on your situation and arrange for a replacement. While you’re waiting for your replacement aligner, please wear the previous one so you don’t lose progress.

For medical emergencies, always contact your doctor or emergency services depending on the severity. For dental emergencies, contact your local dentist or your local dental emergency service.

During the course of your aligner treatment, anything except essential-for-health dental work is strongly advised against. This generally applies to all aligner systems. A procedure as simple as a filling or a crown or veneer can change the shape of the tooth, meaning that the aligners will not fit correctly from that point forward. If urgent work is needed please contact the website live-support team who will guide you in regards to the aligners. 

Unlike other aligner systems, we provide one set of retainers completely FREE! (These normally cost £80-£200). The best way to keep your teeth straight after treatment is to wear your retainers every night while you sleep. Replace them every six months to keep them fresh. 

Retainers are custom-made dental devices, usually in a slightly thicker material than the aligners, designed to maintain the newly aligned positions of your teeth after completing clear aligner treatment. They help prevent your teeth from shifting back to their original positions, ensuring your smile stays beautifully aligned. Retainers are an essential part of post-treatment care to preserve your results.Unlike other aligner systems, we provide one set of retainers completely FREE! (These normally cost from £80-£200)

You should change your aligners every 2 weeks. There are lots of apps and reminder systems (we usually encourage you to set a 2 week reminder on your phone) but we know everyones life and schedules are different so these reminder systems are never 100% accurate. In general they should start to feel looser at the end of the two weeks, however sometimes they do not. If you are unsure, please contact your 24hr support specialist on the website livechat.
