Q. Dear Dr. Moore, ten years ago I had RCT done for two of my teeth (left upper – 10, 11, i think) they were crowned in nice tooth colored crowns (matched my teeth color exactly)…now there was a small gap that appeared in between one of these crowns and another natural tooth so food impaction resulted , i needed a gum cleaning last week. Now doctor says he has to replace the crown as the space has to be closed. He also suggested gingivoplasty before the new crown is placed. I am also concerned about the new crown not being of the same color as my tooth. Can you please advise ?
