This is a very common question. A root canal is a procedure that is done in order to remove bacteria from inside the tooth. The roots of the tooth remain, but the canal that goes through them is cleaned and sealed. Crowns are a type of restoration that helps to strengthen weakened teeth and a completely separate procedure from root canals. Sometimes both are necessary, however, it we are simply dealing with a weakened tooth, a crown can be completed without doing a root canal first.
