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

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

I did not have any sensitivity. I did see results rather quickly. You have to push up from the bottom of the tray to get them to release. I think I had one tray I had to manually take out of the tray out of twelve. Better than strip whiteners.

I think the prefilled tray works best on teeth that are straight. Whitens the hell out of them if you leave it on a little longer than recommended. Don’t go nuts with it though because it will bleach your gums.

The top and bottom mouthpieces are comfortable and easy to put in/on. Mildly disappointed in overall results but I'd be willing to try the 15% sometime

This work fast- so easy to apply and saw immediate results on 15 minutes. Looking forward to see what happens over the next few uses. Previously used the custom trays from the dentist with opalescence (paid thousands for the custom trays). and these trays seem more hygienic being disposable.

These are a great purchase. They whiten teeth fast

We have used these after trying others and found them to be the only ones that worked! They can burn your gums so expect some sensitivity but it’s not too painful. After multiple treatments the color changes last longer than expected

Expensive. They work pretty good but are extremely difficult to apply and keep on. Easy to waste if not applied perfectly.
