The importance of a root canal procedure
When the tooth pulp becomes infected or is damaged, a root canal procedure may save the tooth from extraction. Pulp damage or infection results in tissue death because it cannot heal on its own. Bacteria may enter the pulp via a deep cavity, a broken tooth, or a loose filling.
The bacteria will damage the pulp over time. Infection in the bone may result from germs entering the root canals. The bone will weaken and eventually break down if an infection sets in. Due to swelling of the supporting ligaments, the tooth will become dislodged.
An injured pulp causes temperature sensitivity in the affected tooth. Some individuals have constant, throbbing agony, while others experience discomfort just during eating. The infection will rapidly spread without treatment. The tooth may eventually become loose and need extraction.
When a tooth is severely decayed, broken, or missing significant bone due to periodontal disease, a patient may choose to have it extracted rather than endure the pain of trying to save it. However, losing a tooth may cause other teeth to shift. This can cause misaligned teeth and may make eating a challenge. The dentist may determine that the tooth can be saved and the discomfort relieved with root canal treatment.
A dental implant is a good alternative to a tooth extraction if it is not possible to save the tooth. However, if at all feasible, it is preferable to preserve the original tooth, since an artificial tooth can never replace the performance of a healthy, real one.
