The outer portion or Crown of a tooth is a three-layered structure namely – Enamel, Dentin & Pulp. If the tooth decay is limited to the first two layers, it can be corrected with Filling/ Restoration. In case the tooth decay reaches the third layer and causes inflammation or infection of pulp, an RCT or Endodontic Treatment is needed.

When a patient undergoes a root canal, the inflamed or infected pulp is removed by your dental specialist and the inside of the tooth is carefully cleaned and disinfected, restored and sealed.
