Crowns are a type of dental restoration which, when cemented into place, fully cover the portion of a tooth that lies at and above the gum line. In comparison, fillings are dental restorations that fill in or cover over just a portion of a tooth. Since dental crowns encase the entire visible aspect of a tooth, a dental crown in effect becomes the tooth’s new outer surface. It holds the tooth and protects it from fracture and functions as a normal tooth in the mouth

After your root canal procedure is completed, the next step is to place a permanent filling in the tooth which is called a “core”. You may or may not need a “post” in the tooth, which is a small pin that is placed for durability and strength.

 A tooth that has had a root canal is a weaker, more brittle tooth. It can break and fracture easier than any other tooth in the mouth. Because of this it is very important to also place a crown (cap) on the tooth to make it a stronger tooth that can function normally in the mouth and can serve you for a long time.
