I had to have two cavities filled and an old mercury filling replaced in the process. I braced myself for an annoying procedure....and for the needles (for numbing). The process wasn't all that bad. They even were great in handling my needle phobia. I felt no pain. They had me use a dedicated oxygen system (a safeguard in removing toxic mercury.) And they were careful to explain the process as we went along. The foot massage was a great distraction, too.
