Endodontics (or Root Canal Treatments) involves the removal of the inflamed or damaged tissue from inside the tooth. The tissue is known as the pulp, and it consists of the nerves and blood vessels that are important for the growth and strengthening of teeth. When the pulp becomes infected, patients will experience moderate to severe pain stemming from their jaw. Failing to have the pulp removed will not only result in a gradual increase in pain, but the infection could also spread throughout the mouth.
The pulp gets removed through a tiny hole (called the canal) drilled through the tooth enamel. Once the pulp is removed, the canal gets cleaned and filled in order to avoid the possibility of future infections.
