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

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

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.

Works quickly and does lighten your teeth

These work well. But I did notice that the box I bought from the dentist office for the same price has 15% hydrogen peroxide and these are only 10% hydrogen peroxide. They are also kept In the refrigerator when purchasing them through your dentist office and will last six months past the expiration date if kept refrigerated.

Used for 45 min and minimal pain

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.
