I have decalcification spots on most of teeth caused from braces. I have had composite resin put on 3 of my teeth and matched with the color of my surrounding teeth. My 3 were because the decalcification was so bad. My dentist said I will eventually have to have my top and bottom 8 teeth done later in life. So I was wondering if I could just have them all done at once and redo my fillings and make my yellow resin white even though my other teeth will be yellow.
