I have this white stain on 2 of my teeth. It's scaring me because I don't know if it's going to come off. I've started to brush my teeth more and drink more milk to keep my teeth health </font color> y and to prevent those white stains from going on any of my other teeth. Does anyone know what the white stains are? Could it be from drinking too much soda, eating too much candy or not drinking enough milk?
