Root Canals

Root canals are tiny passageways that branch off from beneath the top of the tooth, coursing their way vertically downward, until they reach the tip of the root. All teeth have between one and four root canals. Many tooth problems involve infections that spread to the pulp, which is the inner chamber of the tooth containing blood vessels, nerves, and other tissues. When the infection becomes worse, it can begin affecting the roots. A traumatic injury to a tooth can also compromise the pulp, leading to similar problems. A diseased inner tooth brings a host of problems including pain and sensitivity as the first indications of a problem. However, inside of the tooth, a spreading infection can cause small pockets of pus to develop, which can lead to an abscess. Root canal therapy is a remarkable treatment with a very high rate of success and involves removing the diseased tissue, halting the spread of infection and restoring the healthy portion of the tooth. In fact, root canal therapy is designed to save a problem tooth; before the procedure was developed and gained acceptance, the only alternative for treating a diseased tooth was extraction.

Root canal treatment usually entails one to three visits. During the first visit, a small hole is drilled through the top of the tooth and into the inner chamber. Diseased tissue is removed, the inner chamber cleansed and disinfected, and the tiny canals reshaped. The cleansed chamber and canals are filled with an elastic material and medication designed to prevent infection. If necessary, the drilled hole is temporarily filled until a permanent seal is made with a crown. Most patients who have root canal experience little or no discomfort or pain and enjoy a restored tooth that can last almost as long as its healthy original.

Tooth Extractions

In some cases, it may be necessary to extract a tooth. This can happen for a variety of reasons such as cases where a deciduous "baby" tooth is reluctant to fall out, a severely broken down and non-restorable tooth is present, or a "wisdom tooth" is poorly positioned and unable to fully erupt into place.

Tooth extraction procedures today are far less painful than ever before, thanks to powerful anesthetics and sedatives. In many cases, a patient who has a tooth pulled experiences little or no discomfort and only minor bleeding.

Before a tooth is extracted, the area surrounding the tooth is numbed with a topical or injectable anesthetic such as Novocaine.

Patients with extracted teeth sometimes need to take an antibiotic, and at the very least, take precautions following the procedure to ensure that infection doesn't occur.

Smoking, vigorous brushing and rinsing, and drinking liquids through straws are discouraged during the post-operative period because they hinder healing and may cause the wound to open. Cold compresses applied to the outside cheek near the extraction area can help reduce any swelling and promote faster healing.
