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. Root canal is a treatment to repair and save a badly damaged or infected tooth instead of removing it.
