Root canal is a procedure that removes germs from the diseased root canal of a tooth and keeps it from becoming infected again. Our teeth have an enamel coating on the exterior, a second layer of dentin on the inside, and a soft inner core that extends deep into the root of our jawbone. The dental pulp, which is made up of connective tissue, blood vessels, nerves, fibroblasts, and odontoblasts, is found in this core. When deterioration reaches the soft-core, the pulp becomes irritated or infected, and it might even die. This must be corrected, and a root canal is required to preserve the tooth and remove the decay. After the diseased pulp is removed, the interior of the tooth is thoroughly cleansed and cleaned before a filling is put to close the gap. This procedure preserves the native tooth.
