I went in to have Zoom whitening done for the first time two days ago and I must say it has been one of my worst experiences ever!! The pain was really bad to a point that I was in tears after the procedure. I just thought to my self it will be over soon and it will be so worth the pain at the end. Unfortunately that was not the case. The next day I woke up to upper gum turning red/purple. My sister also had the procedure done with different doctor and clinic and she advised me it was not normal. So I called my dentist and she told me to come in. She explained to me that this is something that happens sometimes because the protective beerier had moved and the solution leaked in. I think my gums are getting worse and I do not know what to do ?? Any suggestions ?
