Randy, you said "fluoridation opponents dishonestly claim fluoridation is a form of medication without providing a shred of proof."  The following is my proof, and rebuttal.  Follow the logic...

1) According to Websters dictionary Medicine is "the science and art of dealing with the maintenance of health and the Prevention, Alleviation, or Cure of Disease." Medication prevents disease

2) According to the same source Medication is "the act or process of medicating".  Or, administering medicine.

3)According to the ADA statement on fluoride found here: http://www.ada.org/en/public-programs/advocating-for-the-public/fluoride-and-fluoridation/5-reasons-why-fluoride-in-water-is-good-for-communitiesfluoridation 

"Fluoride in water is the most efficient way to prevent one of the most common childhood diseases – tooth decay."  The ADA called tooth decay a disease.

4)Therefore fluoride is considered a medication since it is used to prevent the disease tooth decay (according to the ADA).
