Root Canal Treatment also is known as Endodontic Treatment is a procedure done when the tooth decay reaches the pulp (innermost layer of the tooth) causing inflammation. It is necessary to save the damaged tooth from extraction. This procedure is done by an Endodontist who is known as a Root Canal Specialist. The procedure involves. The endodontist removes the inflamed or infected pulp, carefully cleans and shapes the inside of the root canal, then fills and seals the space. Afterward, you will return to your dentist, who will place a crown or other restoration on the tooth to protect and restore it to full function. After restoration, the tooth continues to function like any other tooth. Needing a crown after a root canal depends highly on the location of the tooth in the mouth—teeth towards the back of the mouth like molars and premolars are needed more for chewing, and generally require crowns, where incisors or canines which aren’t needed for chewing don’t always require crowns.
