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.

Toothache - Why Won't My Tooth Pain Go Away?

There are many causes of toothache and pain in the area of the mouth. When experiencing tooth pain and/or swelling, it is important to see your dentist to have the area evaluated. The pain and/or swelling is most often related to a disease process that originates within a particular tooth.

The pulpal tissue within the tooth can be irritated by bacteria, external traumatic events, repetitive or extensive dental procedures, or even periodontal disease which can lead to a toothache. When this irritation occurs, the pulpal tissue reacts by becoming inflamed. Since the pulpal tissues and the tissues supporting the tooth have a rich supply of nerve fibers, the inflammatory process can cause pain as these nerve pathways are stimulated. Additionally, the pulp tissue is encased inside tooth structure and it cannot swell and expand in reaction to injury like tissues in other areas of the body. When the injured pulp tissue attempts to swell within the confined root canal space, the pressure buildup can cause a significant toothache.

Pain originating from the dental pulp can be either "spontaneous" or "elicited." Spontaneous pain occurs without an identifiable stimulus, whereas elicited pain occurs only in specific situations. Elicited pain requires a specific stimulus such as drinking cold or hot fluids or biting on the tooth.

As is typical anywhere in the body, the initial stages of a disease process do not always cause symptoms. Millions of teeth have irreversible pulpal disease yet the patients have no clinical symptoms. Most of these situations will become evident when the dentist obtains a thorough history, does a clinical examination, performs specific tooth tests, and takes a series of well-angulated radiographs. It is important to note that pulpal disease can refer pain to other areas within the head and neck.

If the results of the endodontic examination indicate that root canal disease is not the source of the patient's symptoms, then the dentist must consider other possibilities. When attempting to identify the source or cause of facial pain and/or swelling, the dentist must consider that the symptoms could actually originate in a tooth (endodontic disease), the gum tissues (periodontal disease), the muscles (myofacial pain), the joints (TMJ), the sinuses (sinusitis), or even the surrounding vascular (blood vessels) or nerve tissues. Tooth pain requires an accurate diagnosis so that the proper treatment can be recommended. At times, various medical and dental specialists may need to be consulted before an accurate diagnosis can be determined.
