Does adult develop dental fluorosis? i am 20 years old & have mild white spot on smooth surface of my tooths which i discovered recently & i used too much paste for last 4 months . my dentist told its fluorosis .spots are at same location on 4 teeth?

Fluorosis occurs in childhood, up to 48 months of age. This problem is not caused by using too much toothpaste in adult life. By UPTODATE: according to data from the National Health and Nutrition Examination Survey, the prevalence of fluorosis among persons aged 6 to 39 years was 23 percent during 1999 to 2002.

Fluorosis is a process known to occur as the tooth is formed, not from fluoride toothpaste after it emerges. I would expect the 4 teeth involved were formed during a time when you were drinking water with a high fluoride content, as occurs in various regions.
