Opalescence Go - Prefilled Gel Teeth Whitening Trays (2 Packs / 20 Treatments) - 15% Hydrogen Peroxide - Teeth Whitening Kit -Mint - 5194-2

Good prodivt and good resoltes.

These were a second purchase after buying a single box. They were very well and whitening. I bought more to help keep up my whitening once a month.

Easy to use with fast results. I’ve only used 5 trays and my teeth are noticeably whiter.

I've been using this product for years! My only complaint is that in the past couple years, sometimes the outer tray doesn't release after applying it. This didn't use to happen, so it must be a QC problem. When that happens, I simply leave the green tray in for the duration. Not the most comfortable, but I'm not about to waste the treatment! It's not exactly cheap, but the results are very impressive. I leave the 15% in for 30 minutes, but you should let your gums tell how long is comfortable for you. I find as the days go by, my gums become more sensitive to the hydrogen peroxide, but never too bad.

My dentist sells this at the office!!! I ordered off Amazon because I had shoulder surgery and couldn’t drive to the dentist office to pick some up! I love this whitening product!

My husband likes them but I can't take it! I tried for 3 trays and got my gum burned so bad. I wasted the rest

Easy to use effective teeth whitening product.

Works
