I understand - fluoridation has been immensely helpful. However, should we re-visit our decisions every once in a while and see if we can do things differently? Toothpaste production is now more streamlined. We know the immense benefits of fluoride, so getting it to people in a more concentrated and localized matter can be a next step in helping people with this. Essentially I'm saying it was a potential risk we accepted because the benefits far outweighed the potential risk down the line, but now that we have alternative solutions with smaller potential risk should we discuss them or not?
