Opalescence Go - Prefilled Teeth Whitening Trays - 15% Hydrogen Peroxide - Made by Ultradent - Fluoride - B-5194-1

I’m a dentist and i recommend this to my patients and I use this myself. I use one a month. It makes the super white and i store them in the fridge when im not using them. Really great product and more affordable for patients that want that dentist kind of whitening. Long lasting effect. But be careful if you get sensitive teeth and use as recommended.

Works great and you can really see a difference. Would buy again but it is not available yet.

So glad to find this on Amazon at a slightly cheaper price. We usually buy this from the dentists office.The first time we used it, we didn't see any change until a few days later. And after the 2nd use it definitely improved the yellow stains of our teeth. In our experience the whitener needs to be used at least twice to see results.

My expectation was much higher then what it offered

I have used this product three times now. Once a week since I purchased it and I have seen not even the slightest difference. I was influenced to buy this product when I saw someone on TikTok using it and believed I saw a difference. I believe this product only "appears" to work if you already have relatively white teeth. Would not buy this product again and would not recommend this product ever. Do not waste your money on this product.
