Nite White Excel 3 ACP Z 10% Teeth Whitening 3pk Mini Kit

Comment: Eight years ago I bought Nite White from my dentist and after the first night my teeth were very white, and I saw a huge difference. It was mildly irritating to my gums and made my teeth very sensitive, but it was bareable and the sensitivity lasted only one day. I loved the results so much that I wanted to use it again, but was told by the dentist that there were new products that were as effective with less time. Since then I've tried other brands obtained from my dentist, such as Rev (extremely painful, and useless; no difference at all: This felt like my gums were in hydrochloric acid); Colgate (again no difference); Day White (again, it made no difference) So, I decided to go back to what worked so well the first time, but no dentists sold it anymore. Then I decided to look for it on the internet, and got it from Amazon. To my disappointment, it did not make any visible difference at all. All I got were sore gums. Important to know is that I don't drink coffee or tea, don't smoke, or have heavily stained teeth for other reasons. VERY DISAPPOINTING & A WASTE OF MY MONEY.

Comment: My dentist wanted to charge me 75.00 for whitening! This box does it without the MAJOR COST! Love it!

Comment: I like these but you need a few repeats to whiten your teeth. However, it is very mild on my gums and teeth. I don't feel sensitivity after each use.

Comment: as the work my dentist does. This is the same chemical compound used by my dentist in NYC. It works well and is cheaper when purchased on-line than through your dentist. Be certain which concentration you are ordering. I prefer the 10% solution, for overnight applications.
