The hygienist, Lisa O'Sullivan, is a gem and just the best there is. I had procedures last December that required the use of clorhexadine rinse that stained my teeth brown--I looked like a lifelong smoker. And I am kind of dental-phobic. She got every last bit of the stain off--in a single session--and with no pain at all.
She is the gentlest and kindest hygienist, I would never go anywhere else. If you are afraid, go see her. It will be health and life changing.
