|Why Root Canal Treatment is Needed|
|Root canal treatment is required for two main reasons: infection or irreversible damage to the pulp. An untreated cavity is a frequent cause of pulp infection. The decay weakens the enamel and dentin of the tooth until it opens into the root canal system, letting bacteria infect the pulp. Infections inside teeth don't respond to antibiotic treatment. The inflammation caused by the infection restricts the tooth's blood supply, so antibiotics in the bloodstream can't get to the infection very well. The reduced blood supply also limits the pulp's ability to heal itself.|
The pulp also can become injured by trauma, a fracture or extensive restorative work, like several fillings placed over a period of time. Sometimes, a common dental procedure can provoke the pulp to become inflamed. For instance, preparing a tooth for a crown sometimes conducts to the necessity of root canal treatment.
It often happens that inflamed but not infected pulp heal and return to its normal condition. Your dentist may want to check the tooth to see if this happens before doing root canal treatment. Sometimes, though, the pulp remains inflamed, which can cause pain and may cause infection.
When the pulp becomes infected, the infection can affect the bone around the tooth, causing an abscess to develop. The aim of root canal treatment is to save the tooth by removing the infected or damaged pulp, treating any infection, and filling the empty canals with an inert material. If root canal treatment is not performed, the tooth may have to be pulled out.
Of course, it is better to save your natural teeth if at all possible. Because of an empty space of extracted tooth, neighboring teeth can come out of line and can be overstressed. Besides, keeping your natural teeth helps you to keep away from more expensive and extensive treatments, like implants or bridges. You have to remember that an infected or injured tooth that needs root canal treatment shouldn’t be disregarded, not only for the reason you can lose the tooth, but also because the infection can spread to other parts of your body.
You have to understand that having endodontic treatment on a tooth doesn’t mean that you'll need to have it extracted in a few years. The reason for doing root canal treatment is often a large cavity. The tooth often is damaged, but if the tooth is covered with a crown after the root canal or, in some cases, restored with tooth-colored composite filling material, the tooth can serve the rest of your life.
