Endodontics (Root Canal) is a branch of dentistry concerned with preventing, diagnosing and treating problems of the dental pulp. The pulp consists of nerves and blood vessels within the tooth. Common reasons one may need a root canal is due to abscesses, tooth trauma, or decay. Through endodontic treatment, also known as root canal, diseased teeth can frequently be saved from extraction. This is beneficial because a lost tooth can lead to shifting and even further loss of teeth in future.
