A Root Canal Abscess

What Causes an Endodontic Abscess?

An endodontic abscess is caused by infected pulpal tissue. This acute disease process then spreads to the outside of the root and enters the bone and soft tissues around the tooth. An endodontic abscess is oftentimes accompanied by a cascade of symptoms. These symptoms may include:

• Pain to hot liquids, touch, or biting pressure.
• Pressure that partially pushes the tooth out of the socket, causing it to contact the opposing tooth first upon biting.
• A loose tooth resulting from infection and subsequent pressure that builds around the outside of the tooth.
• Swelling localized to the tissue around the tooth.
• Swelling that spreads from the gums around the tooth into the cheek, lips, or neck areas. These tissues can become swollen resulting in an exaggerated asymmetry of the face.

In cases of extreme dental infection, the eye can become swollen shut or breathing can become difficult as pressure builds against vital structures. In these instances of severe infection, hospitalization may become necessary.

What Is Involved in the Emergency Management of an Abscessed Tooth?

An endodontic abscess can be extremely painful and emergency treatment is directed towards promptly relieving the patient's pain and, if present, reducing the swelling as quickly as possible. Emergency management would usually include getting the area profoundly numb and then creating a small window through the biting surface of the tooth and into the pulpal space. By opening the tooth in this manner, the dentist can relieve the pressure that has built up inside the tooth and allow the infected area to drain. Usually, the only procedures that are performed at the emergency visit are the ones that are necessary to eliminate acute pain and control the infection. Subsequent care an endodontic abscess will be necessary when the patient is more comfortable and relaxed in order to properly complete root canal treatment. At the conclusion of the emergency visit, the patient may require medications for pain and/or infection control and these will be prescribed by the doctor if they are necessary.

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.
