It often looks likewhite spots or lineson the outer layer of the tooth enamel.

This is why adults do not develop dental fluorosis.

Dental fluorosis is typically mild and should notcause painor permanently affect the way the teeth look or function.

Moderate or severe cases of dental fluorosis that lead to extensive tooth enamel changes are considered to be rare.
