A tooth has three layers enamel, dentin and pulp. When the cavity is so deep that it has reached the pulp, usually pain and swelling occurs due to the infection of the pulp. This necessitates the performance of a Root Canal Treatment. Here all the infection from within the tooth is removed, all the canals in the root are cleaned and medicament is placed. The tooth is sealed so that no infection seeps in after Root Canal Treatment. After performing Root Canal Treatment, the tooth becomes weak and brittle. That’s why Post Root Canal Treatment crown is very important. Placing a crown helps the tooth to be strong and capable of withstanding the forces as in the normal tooth.
Now-a-days even badly broken teeth can be saved by Root Canal Treatment and rebuilding with metal or white fiber post and core with atleast 1-2 mm of tooth is visible.
