Q. Hi, I have had a root canal done about 13 years ago on one of my front teeth. Now, I am starting to see discoloration, and the tooth has a very little chip (which can’t really be seen). My question is do you have any suggestions what I can do to fix this problem of discoloration? Crown? Venners? Also, the rest of my front teeth are very thin on the bottom, also translucent. Do you what that may be from, and how can i avoid having problems with those teeth in the future? I just think that those teeth may be more prone to cracking? Is that true? Thank you very much for answering my questions.
