Opalescence Teeth Whitening Bundle - Opalescence Go 15% Hydrogen Peroxide Prefilled Trays (10 Trearments) and Sensitive Whitening Toothpaste 4.7 Onz - Mint Flavor 5194-5167

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!

Now I was skeptical but it work great. I’m 25 and I smoke and drink coffee teeth is stained but by using this I promise u will see a difference after 2-3 day …

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!

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.

Works well with just a little sensitivity

5 trays used, 5 bad experiences with the quality of the trays. I watched the “Opalescence Go (Trays How To Use)” video twice to make sure I was using the product correctly. Each use had different issues with the upper tray vs the lower tray. Here are some of the problems I ran into: White inner tray not separating from the green outer tray once placed inside my mouth; White inner tray immediately falling out of the green outer tray, prior to placing in mouth; White inner tray not sticking to my teeth; Once used and the inner trays removed, chunky residue was left on my teeth, It was hard to rinse and brush off my teeth; Product seemed dried out.I ended up returning the product. I'm not sure if I'll give this a second chance.

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.

This is the best teeth whitening product that I have ever used. Loved that it's already in the tray and has a very pleasant minty flavor! 2 thumbs up!
