Research has shown that root canals have a 90-95% success rate. Thus, root canals are time-tested and highly successful.
However, root canals may fail in certain situations despite an endodontist striving for perfection. A few of the reasons that may cause a root canal to be unsuccessful are:
During the root canal, a fracture or crack in the tooth may be detected
If this occurs, depending on the size and location of the fracture, the tooth may be jeopardized. A root canal specialist looks through magnification glasses throughout the root canal procedure and will inform you if a fracture is recognized.
The root canal may be inaccessible:
During a root canal, the inside of a tooth is cleaned and filled. The inside of a tooth consists of a hollow space containing the tooth’s nerve. A tooth with a cavity will sometimes produce extra tooth structure inside the tooth to protect the nerve. This extra tooth structure that is produced inside the tooth can actually completely fill the hollow space over time. In this situation, the tooth is referred to as “calcified”. However, the success rate of a root canal in this situation is still high.
A piece of an instrument may break during the root canal:
Despite the meticulous and careful nature of your dentist, an instrument may break during a root canal. If a tip of an instrument breaks inside a tooth during a root canal and cannot be retrieved, your dentist will notify you and all accessible areas of the tooth will be cleaned and sealed. Many root canals are still successful in this situation.
A tooth is perforated during a root canal:
The shape and structure of teeth vary. One tooth may have a straight root while another has an extremely curved root. As a result, a dentist may believe a tooth is curving one way even though it curves differently. In this situation, an instrument can potentially perforate through the side of the tooth. Depending on the perforation’s size and location, many possibilities exist. If this occurs, the dentist will inform you and discuss the various options.
