Yes, I have been using Fluorodex toothpaste for 2 weeks now to prepare for this procedure. I will continue to use it until it's gone. I think it really helped. It is amazing the list of things you cannot eat or dink for 48 hours (berry pie, coffee, tea, red sauce, wine, mayonnaise, ketchup, mustard, etc).
The ZOOM is nothing short of a miracle. My teeth are really bright and white, but not in a fake way.
