Fluorosis is characterized by what?

• A. Aesthetic mottling of teeth caused by excessive exposure to fluorine compounds
• B. Tear staining
• C. Gum disease
• D. Tooth decay due to sugar

Answer: (A)

Fluorosis is about cosmetic changes to enamel that result from too much fluoride during tooth development. When children ingest excess fluoride while their teeth are forming, enamel mineralization is disrupted, causing mottled appearance—white opaque areas that can develop brown stains or even pits in more severe cases. So the defining feature is aesthetic mottling of teeth caused by excessive fluoride exposure. The other options don’t fit because tear staining isn’t a dental enamel issue, gum disease affects the gums, and tooth decay from sugar refers to caries, not enamel mottling from fluoride.
