Correct answer: D — Excessive systemic fluoride ingestion during enamel development (birth to approximately age 8)
Dental fluorosis results from excessive systemic fluoride ingestion during the critical period of enamel formation (birth to approximately 6-8 years for most permanent teeth). Sources include swallowing fluoridated toothpaste, fluoride supplement over-prescription, and high-fluoride drinking water. Severity ranges from mild (white flecks/striations) to severe (brown staining with pitting). Fluorosis at 0.7 ppm water fluoridation is typically very mild and aesthetically acceptable.
