Review on Opalescence Go Whitening Trays - Preloaded, 15% Hydrogen Peroxide - Mint Flavor by Que Wade

This product was recommended to me by my dentist before I replaced a crown on my front tooth. I ended up having to do the treatment twice - the first time I felt sensitivity with daily use so I only did it from time to time. I ended up feeling like my teeth could be whiter so I bought this product again and continued despite the sensitivity. I had good results. My first photo shows my teeth before. (The lighting is a little different than the other photos - sorry!) The second photo is after my first box was made, and the third is after my second box was made, one tray a day.
