Yes! OvernightSmile Aligners really work and have been proven in countless clinical studies to work effectively. In fact, all most all aligner systems work and have become the main way to straighten teeth in the last 10 years. Our patented orthodontic and treatment planning software and SmartMove® technology enable us to generate accurate 3D tooth movements and creates the quickest, safest path to straighter teeth.

We are different from other aligner companies in that our specialist team ensure we only take on cases that are 100% suitable for clear aligner cases. Some people may have more complex dental situations and require an orthodontist to treat this with in person visits. While this is a small minority of cases, it is very important for us to maintain the highest success rates so our team will let you know if you qualify for OvernightSmile® aligners during the free live consultation.

OvernightSmile’s clear aligner treatment comprises multiple sets of precisely fitted, custom-crafted clear plastic trays that are free from BPA. Each tray is slightly closer to the your ‘perfect smile’ so every time you change a tray, your teeth slowly and safely move a little closer to the perfect position. 

This entire process is meticulously planned in advance by a registered dentist or orthodontist affiliated with OvernightSmile, who thoroughly evaluates your case. You’ll start wearing a new set of aligners as per the schedule, progressively moving toward your desired smile. We simplify the process by conveniently delivering your aligners directly to your doorstep.

Once you’ve sent back your impression kit you will receive your treatment plan within 24 hours! Once you have approved this, it takes us only 7 DAYS to make your clear aligners and we will ship it straight to you (most aligner systems take 4-6 weeks to do this!). 

Our aligner system is designed with flexibility in mind. You can get great results from only 14 hours wear per day (that means while you sleep and a few hours before bed). However, the longer you wear them per day, in general, the faster you will achieve the desired result.

We use a Live consultation with dentists and clinical specialists for all new customers, to always make sure we select the right patients who will have successful treatment, this is how we differ from other aligner companies, a lot of whom, will take on anyone and this is why we have the highest success rate by far. 

Our clear aligners are designed to fix and straighten moderate cases of crowding, spacing, overlaps, single gaps and can widen your smile to give you a fuller smile. If you have more complex issues our team will recommend you seek in-person treatment with an orthodontist.

Our professional team of registered dentists and orthodontists will ask you to check-in (usually once every 4 weeks, but this can vary) to check on your progress and advise you. However our team are always available and you can get in touch 24/7 via the website livechat.

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.

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.
