What is dental enamel fluorosis? Does it harm teeth?

Enamel fluorosis is not a disease but rather affects the way that teeth look. In the vast majority of cases, enamel fluorosis appears as barely noticeable faint white lines or streaks on tooth enamel and does not affect the function or health of the teeth. In fact, in many cases, the effect is so subtle that, usually only a dental expert would notice it during an examination. Enamel fluorosis occurs only when baby and permanent teeth are forming under the gums. Once teeth break through the gums, they cannot develop enamel fluorosis.
