Causes And Treatment Of Root Canal Disease

Why Does My Tooth Need Root Canal Treatment?

A tooth generally needs a root canal procedure because the pulpal tissue inside the tooth has become irreversibly injured because of root canal disease. The tooth pulp is composed of elements similar to any other tissue in the body and is susceptible to injury from bacterial decay, repeated or extensive dental procedures, traumatic accidents, or advanced periodontal disease. Pulpal disease occurs in an anatomically complex space termed the root canal system. When appropriate, root canal treatment is directed towards removing inflamed or abscessed tissue, disinfecting, and preparing this space to receive a biocompatible filling material. Once the root canal system has been sealed and a protective crown placed by an endodontist, the tooth can be retained as a healthy and functional member of the dental arch.

What Are the Usual Events That Trigger Root Canal Disease?

Events that may trigger root canal disease include:

• Decay: Dental decay contains bacteria that can infect the tooth pulp. Decay can progress through the outer enamel surface of the tooth into the underlying dentin, which is a hard, yet porous, structure. Ultimately, decay can invade the dental pulp and cause pulpal injury, which leads to an inflammatory condition that can potentially become an abscess. As dental decay and its associated bacteria invade the pulpal tissue, a patient may experience no discomfort or, in other instances, the pain may be acute.
• Traumatic events: The tooth pulp is vulnerable to trauma. A blow to the mouth may lead to a variety of dental injuries. A traumatized tooth may appear whole but exhibit root canal disease at a later date. A tooth may be only slightly chipped or it may be fractured to the extent that its clinical crown is broken off and the pulpal tissue is exposed. In severe situations, the root can be fractured within the bone or the tooth completely knocked out of the mouth, which is called an "avulsion." Frequently, these traumatic events will irreversibly damage the tooth pulp by causing bacterial contamination or by interfering with the tooth's blood supply and its ability to repair. Some teeth are traumatized to the extent that they are not treatable and must be removed.
• Repetitive or extensive dental procedures: The tooth pulp is also vulnerable to injury from repetitive or extensive dental procedures. Subjecting a previously injured pulp to the additional trauma of even the best planned and performed dental surgery may be enough to cause the pulpal tissue to become irreversibly inflamed and the tooth to require root canal treatment. The dentist may or may not be able to predict this outcome in advance. At times, based on the examination and treatment plan, the dentist may recommend the removal of the dental pulp before performing other planned dental procedures. In these situations, the tooth pulp is removed so that it will not become problematic at a later date under a new, and possibly complex, restoration. At times, initiating a root canal procedure through an existing restoration may compromise its integrity.
• Periodontal disease: Infection in the gum and bone around the tooth is referred to as periodontal or gum disease. Advanced periodontal disease may compromise the blood supply to the dental pulp and ultimately, bacteria may enter and infect the pulpal tissue in the root canal space.

An Abscessed Tooth Is a Bacterial Infection

Tooth pain is what usually brings someone with a dental abscess into the dentist's office. These teeth infections can be painful affairs, sometimes accompanied by shooting pains up and down the face. Even if you hate going to the dentist, you'll find that abscessed tooth pain is far worse.

Tooth abscesses are often accompanied by swelling in the cheek or oral tissues. However, sometimes abscessed teeth may have no visible swelling or little pain, so it's important not to wait until you're in severe pain to see a dentist.

If you're diagnosed with an abscessed tooth, you generally have two treatment options: get a root canal, or have the tooth extracted. The tooth infection is deep down inside the tooth root, and the only way to cure it is to clean it out.

Root canal treatment lets you save a tooth even when the tooth's root has become infected. An endodontist or root canal dentist will open up your tooth, clean out the infected pulp inside, and replace the damaged tissue with an inert material. Once a dental crown is placed, you're left with a tooth that looks and feels just like all the others in your mouth.

Tooth extraction is also known as "pulling a tooth." Thanks to modern dental anesthetics, it's not as painful as cartoons might lead you to believe. Your dentist will explain your options for replacing the tooth. Some people opt for dental implant surgery, while others choose a dental bridge or partial denture.
