Unlikely: Fluoride allergy is highly unlikely. In fact I am highly skeptical that it even exists. Fluoride may cause upset stomach, but that is not the same as an allergic reaction. Some city water contains many chemicals and impurities that are very bad for you. I would recommend filtering your water with a brita or something similar.
