Staff and facility were very nice. Went in for Zoom whitening and got through 1/2 of it and had to stop since my gums were burning. When I left I told the girls that my gums had white marks on them they said would go away. They turned bright red after and I read online that those are chemical burns where they didn't get the protective gel. My teeth are not any whiter than before and my gums have to heal but I still had to pay for the full session of the Zoom. Not impressed with the Zoom at all.
