Root canal therapy can help save diseased or damaged teeth. This treatment is necessary when the soft tissue inside the tooth (or pulp) becomes infected. Because the pulp contains nerves and blood vessels, it causes a lot of pain and discomfort when inflamed.
A pulp infection or inflammation is often caused by the following:
- A deep cavity or filling
- A chipped or cracked tooth
- Another serious tooth injury
In these cases, bacteria will enter the pulp, causing infection and/or inflammation.
Root canal therapy may be the right solution for people with pulp issues. During the process, the affected tooth will be numbed and the nerve or pulp removed from the pulp chamber. Each root canal is cleaned and the treated canals are filled with a rubber-like solution to seal them. (Later the solution is removed, and the tooth is restored using a crown or a permanent filling to improve its strength and appearance).
