I am afraid you are peddling old science. Read some papers from this century. My standard question to DDS's - when did you last research the subject? 
First, as a dental professional, you should know that the real benefits of Fluoride come with topical application. You cannot deny that one, because I am willing to bet that Fluoride application is on your list of services. Hard to apply Fluoridated water topically unless you swish each mouthful of water around your mouth for long periods. Not sure that will work. Hint, try Fluoride toothpaste.
Second, You, as a dentist, have no right to prescribe enforced medication to the general public AGAINST THEIR WILL. 
Third, Delta Dental pushes Fluoridation. They are a special interest group. They supply you with info they want you to have. They supply the City Council the same. They also fund politicians. They are getting the City to feed a toxic sustance to the public against their will. You, the dentist, is supporting them.
