Opalescence Go 10% - Prefilled Teeth Whitening Trays Kit (10 Treatments) - 10% Hydrogen Peroxide - Mint Made by Ultradent Products. Go Teeth Whitening Kit -Mint- GO10-5193-1

Works great unless you have a crack in your tooth and then the pain begins. Easy to use no taste just creates saliva.. unfortunately I could only use two packets due to crack and tooth.

Love this item! Whitens teeth very well.

I have used these for years. May dentist even sells them and recommends them. But I can watch for sales on Amazon. They do eventually whiten your teeth. They do work. It just takes a lot of of them. Way more than one box. To get as white as I would like. You can tell a little difference after one box. It’s a good product. It is very handy to have The product already in a mouthguard. But does not work as well as when I had a mouthguard and bought syringes of teeth bleach. Eventually, with enough boxes (4ish) and many nights of wear I got off of the charts white according to my dentist.

Only whitening product ive used that I have seen a noticeable difference. Takes until the next day after treatment for me to really notice a change. Occasionally my teeth will be a little more sensitive for a couple days after using but definitely tolerable. Will repurchase.

These are worth every penny!! Best whitener and so easy to use

Highly recommended by my dentist. And it DOES whiten my teeth.

These don’t always come out of the tray like they should. It’s hit or miss. Instructions say to bite down then the strips should adhere to your teeth and you can then remove the tray. However, sometimes the bleach strip doesn’t pull away from the tray. They do work though!

Great quality whitening gel with trays, recommended by dentist. Really White's, second time purchased.

good for quick touchup
