Have a toothache?
Understanding the problem:
Pain occurs when a pulp is damaged or has died there is an increase in blood flow and activity occurs in the tooth and this causes pressure to build. Pressure in a tooth cannot be relieved on its own. If an infected pulp is not removed, pain, swelling, and infection can spread to the bone around that tooth and other teeth which can cause damage to your adjacent teeth or cause the infected tooth to fall out.
Endodontic treatment involves removing the damaged or dead pulp. The canal is then reshaped and filled with a rubber-like material, to prevent recontamination of the tooth. The tooth is then permanently sealed.
