Root canal treatment helps protect damaged teeth. When the pulp (the soft area inside the tooth containing the nerve, blood, and lymph vessels) is damaged to such an extent that it cannot repair itself, the pulp dies. Bacteria cause this in broken or deeply carious teeth. 

If the damaged or sick pulp is not removed, the tooth and surrounding tissues are exposed to infection. As a result, the tooth is completely lost. 

The jawbone surrounding the tooth is also inflamed and eroded. Abscess occurs in this space, pain and swelling are seen.

During root canal treatment, the tooth is anesthetized so that painless and painless treatment can be performed. When the decay is cleaned and the essence of the tooth is reached, the diseased tissue is removed. Nerve and tissue residues are cleaned. The tooth canal is shaped up to the root tip. Healing is accelerated by administering some medications. Between these sessions, the tooth is closed with temporary fillings. After the inflammation is over and it comes from the root tip, the canal is filled up to the root tip with a special filling material. In some cases, these sessions are not needed and it is possible to complete the root canal treatment in a single session.
