This really works!
Excellent result - beyond expectations!
Works better then all the others I have tried.
The easiest, most effective, and least expensive tooth whitening I have ever seen
Along with bad coffee and tea staining, I have naturally off white teeth. I'm pretty certain my enamel layer has thinned, as well. My dentist advised me to use Opalescence Go. I really didn't have high hopes in seeing much of a difference from using the product. The first couple days of use I didn't notice much change. Then started to see change on day 3. By day 6, my teeth were whiter than I had seen them in ages! I was amazed. Even the stained cracks in the enamel on my front teeth whitened. I used daily for the first 6 days, then every other day for 3 days. I have one tray set remaining that I'm saving for emergency use until my next order arrives. Stained teeth definitely make you look older, and the whitening succeeded in helping me to look a little bit younger, which is one of my reasons for whitening. I will be working this product into my budget and buying on a regular basis. Just ordered my second kit. The shipping is fast and best of all, free. I am trying to use alternatives to Amazon whenever possible. I highly recommend Dental Health Essentials, which I found while searching for other places than Amazon to buy Opalescence Go.
