I have discoloration on my eye teeth only abover the enamel. What can I do to make color even?

Not related. This is a dental question and not an eye problem!
Discolored teeth . Teeth discolor for many reasons. Recession, and staining are just a few of those reasons. You should see your dentist to decide if bleaching is a good option for you, or if a filling or bonding may be needed.
