I ordered an impressions kit over 2 months ago and never received it. I called their customer service line a bunch of times to follow up on where my impressions kit was, I always received the same answer, that they’ll follow it up and get back to me. (half the time it would go straight to voicemail so this is if they even bothered to answer) After about 4 weeks I requested a refund and they told me to allow 5 more days for the delivery status to update and if it didn’t I would get a refund. It of course didn’t update, I never got a refund and I didn’t get an answer when I tried to call about it either. So I posted a review about my experience. I got a call from them within a couple hours and they told me that a refund was already pending but THEN threatened that if I didn’t take down the review within 2 hours they would cancel my refund because apparently processing a refund for a LOST PARCEL was a ‘good will gesture’ ? I took the review down thinking I’ll maybe repost it when I got my refund but I never did get that refund anyway, so I’m assuming he was lying just so I would take down the review. Horrible excuse for customer service, it’s actually laughable, making it SO difficult to just process a refund for a parcel that didn't even make it to the courier (they can also see this from the tracking number) AVOID AVOID AVOID! Thankful this happened at the first hurdle and I didn’t receive the impression kit let alone the aligners and have to deal with this company long term *EDIT* I just got a call from them again after posting this saying the same, ‘that they’ll issue a refund if I take down the review again’, I ofc said no this time and he threatened that I’d be hearing from their legal team and that I wouldn’t be getting any refund now. I wasn’t still betting on that refund now anyway, it’s been 2 months.

Ordered aligners in September 2024 (£799) and wore them 20hrs/day as required. However, discovered in January 2025 that my final retainer was malformed and didn't fit. Getting it right has required multiple separate impression kits, including a second full-price kit I had to buy myself (£39), on top of the original kit and a third, fourth and fifth sent after the company repeatedly lost my return in transit, or found the aligners 'didn't pass quality control and needed remaking'. So far that's £877 paid out, and I still don't have a retainer that fits. Alongside that: 20+ calls, countless emails, return kits sent without return labels multiple times, being told their "IT system was down" repeatedly, and being wrongly told a return hadn't arrived when I had email confirmation it had. In March 2026 they offered a free replacement set of aligners as a goodwill gesture after yet another lost impression kit — only to tell me in July 2026, after another failed quality check on their end, that I might now have to pay for it after all. I am still awaiting my replacement kit and customer services have gone quiet, not replying to multiple requests for an update. My teeth alignment has actually gotten worse during this process, not better, because I've spent so long wearing a retainer that doesn't fit. Customer service resolves nothing, repeatedly promises to chase up orders and then doesn't, and at one point requested that I stop using email and livechat to contact them (presumably so no trail of what was said is available?). I gave overnight smile a further week's notice before escalating my complaint and have heard nothing. I am now pursuing this with small claims court.

I do not normally leave negative reviews; however, I feel compelled to share my experience. I purchased a teeth straightening package from OvernightSmile for £838. The initial aligners supplied did not fit correctly, and after a lengthy process involving replacement moulds and replacement aligners, I continued to experience issues with fit and progression of treatment. Communication was extremely poor throughout. Requests for support and treatment reviews often went unanswered, and resolving issues took months. Following extensive correspondence, the company agreed in writing to provide a full refund and requested that I return all aligners. The aligners were returned and received by the company on 26 May 2026. After I posted a review regarding my experience, I was informed that the refund would be processed that day if the review was removed. I removed the review in good faith and was advised that I would receive confirmation once the refund had been processed. At the time of writing, I have still not received the refund, and no payment confirmation has been provided. Throughout this process, I have been given multiple timescales for payment, none of which have been met. Based on my experience, I would not use this provider again and would encourage prospective customers to carefully consider alternative options.

Absolutely awful experience. Ordered over a month ago, no email, text or any other update. Can’t get hold of customer services. Stay well clear.

If a product looks too good to be true, it probably is. I do wish I'd followed this advice before ordering my impression kit. The website promises 24 hour delivery but it took over 2 weeks to arrive. I emailed to find out what had happened to it but I had no reply. It arrived the next day but pieces were missing from it so I was unable to proceed. I emailed again but still no reply. In many ways I am grateful I found out at this early stage and didn't hand over any more money to this company. And I learnt a valuable lesson.

Avoid! Ordered the impression kit. Only came with one set of moulds. Set of regardless. 4 weeks later no correspondence. No reply to emails. Think I've been conned. On to the next one. Avoid!

Ordered my impression kit online which took over 2 weeks to arrive. No reply to any messages or emails chasing this delay. When it arrived it did not contain the 2 sizes of mouth inserts. It was easy to take impressions and they were returned over 2 weeks ago and have not heard anything about the treatment plan or even notification they have received the impressions. I have sent emails and messages online chasing the treatment plan and no response. Therefore I will not be proceeding or giving them anymore money after this initial experience.

After paying for the impression kit and returning it. I have had nothing back. No scans or plans within a day or anything even close. I’ve messaged, called, emailed… nothing. I was told 3 weeks ago that they were sending another kit. Nothing came. I’ve now been blocked from social media. Nothing but a scam company. AVOID Edit**** Within 6hrs of this review I was called. At almost 10pm. Spoken to by the very same person I’ve spoken to on every call. I genuinely think the whole “company” is one guy. He was desperately unprofessional and continually commented on “£39” trying to make out like that was a huge amount for me but nothing to them. He was aggressive and telling me if I took the review down, they would send out another kit. I declined. Here we are a week later and yet again, still no kit. So I repeat, it’s nothing but a scam. Steer well clear
