I had yellow stained teeth. I saw a prior positive review on this provider and made an appointment. They were running a January special. The dentist told me I had great teeth because of my genes.
I had four 15 minute sessions. Absolutely no pain and no zingers. Results are great. I was told that sensitivity is caused by any porous areas in the teeth. I also researched and found that the zoom 2 procedure is less painful to those with sensitive teeth than the original zoom procedure. When I was finished, there was a lady in the waiting room and asked to see my teeth. She said they were beautiful and was going to recommend that her husband have the procedure.
Sorry, I have no before and after pictures.
