What Is A Root Canal? And When And Why Do They Need Crowns?


Vital teeth contain living pulp tissue which has nerve fibers, blood vessels, tissue etc. This pulp may die and the tooth may become non-vital. In the process of getting non-vital the tooth may turn painful. The reason for teeth turning non-vital are many injury, decay, gum disease etc.

This process of doing a root canal is a very accurate and a technique sensitive skilled process and is not painful. Though most dentists do it, it is estimated that most root canals are substandard & some can be redone by specialist and sometimes need special equipment’s.

It is estimated that well done root canal has a success rate of 93%.


At International Center for Dental Care we have coined a statement “patients survive despite doctors” so patient with substandard root canal would be pain free for a few years but ultimately could lose a tooth.

 A well-done root canal can last for years and if infection ever in very rare case sets in can be repeated very easily. Now tooth and bone is very similar in chemical composition. That is why as you grow older and blood supply reduces to the bones they get brittle and a simple fall can cause a fracture.


Capping the Tooth

A root canalled tooth may have part or major portion of it the crown decayed and broken before putting a cap/crown on it. This decay and missing portion must be replaced. Sometime there is very little tooth structure left to hold this replacing material. In those cases, a post is placed in one of the canals of the tooth by removing part of the guttapercha and the post is bonded or cemented.

 This serves like a pillar and the material used to replace the missing portion of the tooth is built around the post and remaining portion of the tooth. This is now shaped and a cap is made to give a dome like structure which is very strong resembling the external shape of the tooth and occluding with opposing tooth.

In rare cases for front teeth the dentist may suggest not doing a crown but usually it requires a post. Root canal techniques have improved over the years and most procedures are done painlessly in one or two sittings
