"Once the root canal is done, we want to rebuild the crown portion. For the most part, after the root canal, the crown portion of the tooth structure is basically damaged or is gone due to some form of cavity or trimmed away to access the chamber of the canal. To do the crown, we need to do a build up or a post because we need to rebuild the inner structure of the tooth. Once that build up or post is replaced, we put a crown over that tooth. The crown can be metal, porcelain, anything to cover the top portion of the tooth to allow function to come back again. It's important that the crown follows the same anatomy structure and the seal around the tooth has to be nice and clean. If it is not, there will be an opening and saliva will bring bacteria underneath the crown and you can get recurrent decay or cavity. Then, the same process will occur again. Now, you don't have the warning that you have a cavity inside your mouth. Once the root canal is done, if you have a cavity underneath the crown, you can't really feel anything until it is too late. It will break down the remaining tooth structure and once you start to feel something, you will have to replace it. Anything below the gum line, the integrity of the tooth will be compromised and have to be removed."
