Final answer:
Endodontic treatment is required for repairing a root canal, which involves removing infected pulp, cleaning, and sealing the tooth.
Step-by-step explanation:
Repairing a root canal falls under the type of dental care known as endodontics, which deals with issues inside the tooth.
A root canal procedure is necessary when the inner pulp of the tooth, containing nerves and blood vessels, becomes infected or inflamed. This infection can be due to severe tooth decay, a crack or chip in the tooth, or repeated dental procedures. The enamel and dentin are compromised, allowing bacteria to reach the pulp and potentially leading to the formation of an abscess. Endodontic treatment involves the removal of the infected or inflamed pulp, cleaning and disinfecting the inside of the tooth, and then filling and sealing it to prevent further infection. The final step often includes restoration of the tooth with a crown or filling for protection and to restore functionality.
It's important to address any signs of tooth decay early. If left untreated, bacteria causing the decay can lead to serious issues not only in the pulp but can also spread to surrounding tissues and even enter the bloodstream.
