Review (5/5): I finally have a bright smile!
This is my second time using opalescence. I got the first kit from my dentist and was really impressed with the results. After using all the whitening toothpastes and other over the counter treatments, I found with this, I finally had white teeth! During the treatment, I did get some teeth burn; it’s powerful stuff! But using a sensitive toothpaste helped leave he ate that. Plus I didn’t mind so much that it hurt because I knew it was working. The whitening agent really gets deep into the enamel. I’m so glad I found these on Amazon because it was a lot less than buying them from my dentist.
