Our professional whitening trays are the same quality used in dental offices, but without the high cost of in-office teeth whitening. Each tray is custom-made to your exact dental anatomy, helping reduce gel leakage, minimize tooth sensitivity, and deliver consistent, effective dental whitening results. Designed to fit your full dental arch, these trays are reusable and compatible with most teeth whitening gels.
How It Works:
Option 1 – Home Teeth Impressions
1 - After purchase, receive a home impression kit with 3 mouth tray sizes (small, medium, large), dental putty, and easy step-by-step instructions with images.

I stupidly melted my whitening trays from dentist, and really didnt want to pay another £400 to get them replaced (even though I had the previous moulds, they said they would have to redo them). So I saw retain and guard had great reviews and would only cost £100. Even though it was just before xmas, they came really quickly and returned my moulds just as they said they would. So nice to get the whole service advertised. I am very happy!
Let customers speak for us
from 49 reviewsI’ve lost / broken my retainer a couple of times over the last 10 years and it’s always cost me £100+ in the Orthodondist to get a replacement. Using Retain & Guard is a fantastic alternative, especially if you have a mould already - convenient, cost effective and quality is just as good as previous retainers.
Fast and great quality
Great sevice and product. Order came in around a week and I was kept informed about delivery dates and questions I had were answered promptly.
Communication was great with any queries and concerns I had, retainer came quickly and amazing quality. Have now got a yearly subscription for a new one every year. Thank you retain and guard :)
I ordered, shipped my model and got the new retainers all within 3 days. Good quality retainers too. Very satisfied
Great company and retainers came fast. Customer service was helpful! Only thing was that you have to pay for postage as not included.
Excellent communication. The instructions given with the impression kit were straightforward.
I ordered extra putty because I thought I might mess it up, which gave me a chance to try again, even though the first try was ok.
The retainers arrived within 1-3 days of them receiving the impressions, exactly as described. It’s good value for money, they fit well and I would highly recommend. I’m very glad I chose the subscription option. Thank you!
Ordered 1mm before but the 1.5mm are excellent
Excellent communication. From the start of the process to me receiving my new retainers it was under 2 weeks. I’m really happy with them, they are good quality. I would buy from here again.
After being given an eye watering quote from my dentist to make a new retainer from the 3D printed mould that they made two years ago that along with a retainer cost me less than they now wanted for the retainer only I decided to look online. This company seemed to offer a good service at a reasonable price and plenty of options. I was a little nervous about sending the mould but the whole thing was seamless and I now have a new strong retainer and mould returned. Excellent service. I like that having my own mould was a benefit as other companies seem not to like this and charge nearly as much. Thanks. I will definitely use you again.
I was a little worried at first, however the team were brilliant with excellent communication. The new retainers are superb quality and fit much nicer than her original ones from the dentist. They look very professional, in brand new condition as expected. Superb value for money, saved a fortune on dentist fees. 5 Star highly recommended
Really happy with my retainers.
Arrived very quickly, used my existing moulds. Very happy with my retainers.
Fabulous service, brilliant value for money, better than a brand I won’t name 😉
I don't leave reviews very often, but this one deserves it. Not gonna lie, I was skeptical to buy a retainer at such low price cause all the fancy companies charge you 300 and above. My retainer just came and I'm just amazed and so happy about the great quality and how perfectly it fits! I'll definitely will be using your services again! Sooo soo happy!
