Fluoride is considered important, if not essential, because of its benefits for tooth enamel. Fluoride incorporation into enamel produces more stable apatite crystals. Fluoride also acts as an antibacterial agent in the oral cavity, serving as an enzyme inhibitor.
Cooking foods in Teflon pans may increase fluoride intake.
