     Root Canal

A root canal is the commonly used term for the main canals within the dentin of the tooth. These are part of the natural cavity within a tooth that consists of the dental pulp chamber, the main canals, and sometimes more intricate anatomical branches that may connect the root canals to each other or to the root surface of the tooth. Root canals are filled with a highly vascularized, loose connective tissue, the dental pulp. This sometimes becomes infected and inflamed, generally due to caries or tooth fractures that allow microorganisms, mostly bacteria from the oral flora or their byproducts, access to the pulp chamber or the root canals; the infected tissue is removed by a surgical intervention known as endodontic therapy and commonly called a root canal.

Tooth Structure

This hollow area contains a relatively wide space towards the chewing surface of the tooth called the pulp chamber. This chamber is connected to the tip of the root of the tooth via thin hollow pipe-like canals-hence, the term "root canal". Human teeth normally have one to four canals, with teeth toward the back of the mouth having the most. These canals run through the center of the roots like pencil lead runs through the length of a pencil. The tooth receives nutrition through the blood vessels and nerves traversing these canals.

When Do I Need Root Canal Treatment?
The common reason for root canal therapy is an infected or abscessed tooth.

Conditions that may lead to the need for root canal treatment can be untreated tooth decay, periodontal disease, trauma, fractured tooth or even repeated dental restorative procedures.

Any condition that allows bacteria to reach to the pulp of the tooth may be responsible for a root canal. If the dental pulp is infected by bacteria and inflamed, besides the strong pain induced, the bacteria may get through the root canals to the area around the tips of the roots (periapical area), creating a tooth abscess.

Symptoms of Needing a Root Canal
A root canal treatment is needed in cases of tooth infections. So, root canal symptoms are similar with the symptoms of conditions that could be the cause or result of a tooth infection, such as severe tooth decay or a tooth abscess.

The most common of the root canal symptoms is pain and discomfort. The pain could be:
• A severe constant tooth pain
• A tooth that hurts significantly on touch / pressure or when biting or chewing.

In later phases, it is also possible that the tooth?s nerve is so much damaged by the infection that the sensation of pain is lost. Even without pain, the infection must be treated before it can spread and damage the jawbone and the periodontal tissues. Besides pain, other symptoms and signs of needing a root canal include:

• Prolonged sensitivity to heat, cold or pressure
• Swelling and tenderness of the gums near the affected tooth
• Tooth discoloration (darkening of only one tooth?s color)
• A chipped or broken tooth
• A persistent or recurring pimple on the gums

If you have any of the symptoms of needing a root canal visit your dentist as soon as possible. Early treatment may save you from a lot of pain, higher treatment costs and increase the possibilities of saving a badly infected tooth.
