Q. I have an overbite (due to sucking my thumb when little) My teeth are slightly discoloured and the front two are slightly too large for my face. I was wondering if crowns could be used to lessen the overbite and shape my teeth, as I don’t think I can go through braces again (I had a very bad experience with block braces to widen my arch…which ended in me not wearing it.) Cost isn’t an issue, but before I go to my dentist I wanted a fist opinion. Many thanks
