I have a tooth, that had a root canal done, that had a Crown on top. The crown cracked off. The dentist said it could have popped off due to the Short Tooth, my overbite, and my Clenching. I want to see if Invisalign can correct this BEFORE I get another crown. As well as my bottom teeth are crowded anyways. What is the Shortest Period I could fix this in? It is embarrassing to be my age with braces or Invisalign. Which is faster? Thanks
