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

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!

Product excels at whitening teeth while not being harsh on ums and surrounding tissue. Results are noticeable after the first application of the whitening trays within 30 minutes! Fantastic!

Works well and doesn't irritate my teeth or gums. Noticed a definite result after the second use, and continued to see results after every use which prompted me to repurchase and go for the toothpaste as well. Will keep buying.

Immediate noticeable whiting. A little pricey.

works really well and fast

100% works. After the second or third treatment my teeth were noticeably whiter to my wife and literally got a compliment on how white they were within a week. When peeling the outer trey off the inner trey, the inner trey does not stick well to my teeth without using my hands but..still whitens. Highly recommend.

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.
