Opalescence Whitening Bundle - Opalescence Go 15% Hydrogen Peroxide Prefilled Whitening Trays and Whitening Toothpaste - Mint Flavor 5194-5166

This product actually worked. My teeth looked brighter.

I was really impressed with this whitening kit—it worked on the first try! I left it on for 45 minutes and noticed a visible difference in the color of my teeth right away. The included toothpaste tastes great—mild and refreshing without being overpowering.Super easy to use, and the results speak for themselves. I’ll definitely be buying it again!

I purchased this exact same thing from my dentist a few months ago and let me tell you my teeth got super white! This was $20 cheaper on Amazon so it was a fantastic deal. This stuff works. I’m just working on getting them even whiter.

Works great but don’t leave on for too long especially if it reaches your gums. I only had on for 15 minutes and my bottom gums hurt for over a week! It felt burnt and was very sensitive!!

Worked well for my wedding. I little expensive but they work.

Quick ship. Great! As expected, thanks. This stuff really works! If your gums are healthy they don't cause irritation, and I'm usually very sensitive. I leave them in for 2 hours each time, and it took two full boxes of treatments to go from a brown so deep it was off the whitening charts to the third lightest possible. I'm happy. Now I'm asking my husband to try it. I use it about every 3 months now to keep my teeth white and attractive. I couldn't believe what a difference this made for me socially. People who wouldn't look at my face previously, like my niece, will look at me and even smile now!

Whitener is effective. However, have had several issues with the bottom fitting and properly staying in place. Contacted customer service for perhaps some tips, but answered by saying it was past the warranty window!! Not a great service…

This stuff is awesome. I’ll admit I saw it at my dentist’s office and then immediately looked it up on Amazon. I’ve tried “opalescence” 30% strength in the syringe from Amazon before, but I think it was either a fake or I didn’t use it right. These trays are idiot proof and you'll have a brighter smile after just a session. I should’ve taken before and afrer photos just to show my 4 days of progress, but you’ll just have to believe me.One thing I’ll note is that I misread the instructions and thought the time was 20 min per tray. This definitely burned my gums some and turned them white, but they recovered quickly and I didn’t have to stop my sessions. I may even keep pushing it to twenty now that my gums seem used to it and I’m seeing such dramatic results. Otherwise, you should stick to the ten min per tray per the manufacturer’s directions.
