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 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 therapy 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.
When restoration procedures such as root canal therapy, crowns, or fillings are not enough to save a tooth, it may need to be pulled, or extracted.
Tooth extraction procedures today are far less painful than ever before, thanks to powerful anesthetics and sedatives. In many cases, a patient who has 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/and 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.
Wisdom teeth are the third and final set of molars that erupt in the back corners of the upper and lower normal adult mouth. Unfortunately, most people experience problems from wisdom teeth; in most cases, this is because the teeth erupt too close to existing permanent teeth, causing crowding, improper bites, and other problems.
If wisdom teeth are causing a problem, this could mean that they are impacted. Impacted wisdom teeth can be extremely painful, as well as harmful to your oral health. Symptoms are easy to spot: severe discomfort, inflammation, and some kinds of infections.
Many people need to have their wisdom teeth extracted to avoid future serious problems. In general, the lack of the four wisdom teeth does not hamper one's ability to properly bite down, speak or eat.
If you experience any of the following symptoms, you may have an impacted wisdom tooth:
- Facial swelling
- Gum swelling
