In conclusion, our study provides strong evidence about the natural history of mild and very mild dental fluorosis during the period between adolescence and young adulthood. Dental fluorosis during childhood diminishes over time. Further, dental fluorosis at this low level had no impact on perceptions of oral health, in contrast to dental caries.
