This works really well! I used it several times and really saw a difference. Unfortunately I had a root canal done and the following day I decided to whiten and I thought I was going to die! I didn’t know my front tooth was going to be that sensitive from the tooth canal. That was my fault and only telling this story as a warning! Do not use this after dental work unless your dentist says ok! Otherwise it works amazingly!
