A. It sounds like you are suffering from flurosis, which is a staining of the teeth by having too much flouride in your diet as a child when the teeth were developing. the most non invasive option would be to try to whiten he teeth. this may cause the staining to blend in with the teeth, but it may also make the stains more pronounced. your next option would be to veneer the teeth but this is more destuctive. hope this is helpful.
