Contrast PM PLUS - 10% Carbamide Peroxide with 3% Potassium Nitrate | Teeth Whitening Gel

For years I have used a product with the exact same carbamide peroxide percentage, purchased from my dentist. Even my dentist's staff suggested recently that I could find an identical product cheaper on Amazon (my dentist charged $43). The product I purchased from my dentist sufficiently whitened my teeth with only 1 overnight application and minimal discomfort, and I used it only once every several months. This product makes virtually no noticeable difference in whitening after using it 3-4 nights in a row, and then again a few days later. I will not use or purchase this product again, but will try the 15% solution.

Very, very convient to use, no hassle if you have your custom trays from your dentist. Also, the taste is A-OK! I have a mean taste bud that cannot put anything in my mouth it does not approved. Having dry mouth has caused a lot of root carries. My dentist recommended this and it really helps to whiten and treat the exposed roots of my teeth. I had to buy another product, because my teeth were so sensitive. For the last two times I have not had the sensitivity. Am getting ready after payday to order some more.

Solid product that did not hurt my gums like other products. I made the fatal mistake of using this on back to back nights. My gums have been sensitive for weeks. This would of happened with any whitening product though, so the fault it all my own. I'm gonna buy this product again.

I've tried 20% solutions and they sting--I feel an uncomfortable burning sensation inside my mouth. This 10% solution is fine for overnight. If I have to do it two nights in a row, fine by me. My teeth look white and beautiful.

Great product

This did nothing to whiten my teeth. Errg! If anyone has any suggestions besides Zoom (too harsh for my sensitive gums) I would love to know! It would be great to actually find something that works!
