Teeth have a soft core called dental pulp. The pulp extends from the crown the visible part of the tooth to the tip of the tooth's root in the bone. When a tooth has a deep cavity ,bacteria can invade the pulp &if left untreated, bacteria and decaying material can cause a serious infection ,a tooth abscess, and even loss of the tooth itself. Signs and symptoms may include swelling, a hole/cavity in your tooth, toothache.

 Overview of RCT
Root canal treatment is done to repair and save a badly damaged or infected tooth instead of removing it. The term "root canal" comes from cleaning of the canals inside a tooth's roots.Root canal alternatives include extracting the damaged tooth and replacing it with a dental implant, bridge or removable partial denture. However RCT if done properly with advanced equipment and qualified specialists has a success rate of 85% to 95% .

 Getting started on root canal treatment
A root canal is usually done by an Endodontist (specialist in RCT) or a general dentist. Root canal
usually takes one (single visit) to three visits. First, you have dental X-rays to check the extent of damage. You also receive a local anesthetic to control pain. A rubber-like sheet called a dental dam is put in your mouth to keep the tooth clean, protected and free of saliva. Decay is removed, and an opening is made through the crown of the tooth to gain access to the pulp chamber. Using small dental instruments, the infected or diseased pulp is removed. It is very important to maintain sterilization and asepesis during the entire procedure.
