Dental fluorosis is associated with which condition?

• A. Tooth discoloration and/or pitting caused by excess fluoride exposure during tooth development
• B. Tooth decay
• C. Gum disease
• D. Enamel erosion

Answer: (A)

Dental fluorosis happens when a child ingests too much fluoride while teeth are still developing. That excess fluoride disrupts enamel formation, leading to enamel that shows discoloration—often white chalky spots or streaks—and, in more severe cases, pits or brown stains. This enameled defect is specifically tied to fluoride exposure during tooth formation, which is why the description of discoloration and/or pitting from excess fluoride fits best.

Tooth decay is caused by acids produced by plaque bacteria that demineralize enamel, not a developmental defect from fluoride. Gum disease involves inflammation and infection of the gums and supporting structures, not enamel changes from fluoride exposure. Enamel erosion refers to loss of enamel from chemical wear (acidic foods/drinks or stomach acid) rather than a developmental defect due to systemic fluoride levels.
