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

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!

Idk how I feel about the product because this is only the second day I’m using, left on for an hour each day and my teeth are so white alreadyBut immediately when I put it on today I felt burning and thought the plastic was just scratching my gums but i think it burnt my gums so be careful :’)

Literally a game changer! My teeth were noticeably whiter after first use! Will be repurchasing and didn’t get sensitivity but would still space it out a few days in between just in case. The trays are really easy to pop in and they stay in and don’t slide around like normal strips

I’ve dealt with depression since a kid, and as an adult I’ve been working to reverse the damage it left me with. My smile is definitely my biggest insecurity. This is the only whitening product that has ever worked for me. I would definitely recommend the 15% and get the toothpaste too. The pictures are in order from where I started to where I am now. These results are with 3 of the treatments and brushing twice daily with the toothpaste.

works really well and fast

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

I started this yesterday. I had done what the directions said to do to get it to stick. The bottom one did not fit my teeth properly. When the bottom part came off, lots of the filling poured out into my mouth. I spit it out, but was concerned. Last night I told Amazon I was returning them. But today, I decided to give it one more shot. It was worse - the upper white part came off with the green today. I followed the directions to get it to stick. I got it to stay on the second time without the green, by pressing the white with my teeth, but I looked in my mirror and saw that the white part did not even go to the top of my upper teeth! So only 3/4 of those teeth would be whitened. I decided I was finished with these. I did not do the bottom teeth. I just spit it all in the trash. I would rather spend more money, because when my dentist uses another system, it is awesome. It lasted for about a year, even drinking tea and coffee. He does not use this. I also feel that this company does not give you good directions as far as whether you should refrigerate or not. I called a customer service rep who said my 15% ones did not need to be. She had to research it. I will be returning this.

As of the writing of this review, I have used 7 treatments. I had quite a bit of sensitivity after the 6th treatment. Took a five day break and then did 7th treatment. Mild sensitivity. I had difficulty getting the bottom tray to stick to my teeth. I eventually used my fingers to put pressure on the teeth. Upper went on just fine. I took pictures from before and after each treatment. I see a bit of difference, but expected more. I will eventually use the remaining treatments and see how it goes. At this point I will probably not purchase again. Glad I tried it though.
