Root Canal Therapy- The Procedure To Relieve Your Pain

Many people flinch when their dentists tell them they need root canal therapy. While dentists are sympathetic to fears of pain, they also want patients to know that root canal procedure has three purposes:

• Stop the root canal symptoms of a toothache;
• Prevent bacteria and pain from spreading into the jaw; and
• Maintain the original tooth instead of replacing it with a denture or bridge.

Root canals are actually channels that run from the root of the tooth, which connects to the bone, up to the top surface of the tooth. The canal contains blood vessels, nerves and the complex cells that make up the living tissue inside the tooth. This lifeline inside the tooth is called the pulp.

When a tooth is decayed or cracked, bacteria can get to the pulp. The acid from the bacteria irritates the pulp and it becomes inflamed; it's the same process you watch when other parts of your body become infected. When the pulp tissue becomes inflamed, it's harder for blood to flow to the tissue, and the resulting pressure creates the pain symptoms inside your tooth.

There are two ways to get relief from root canal pain: perform the root canal procedure, or pull the tooth, clean the gum below, and replace the tooth with a denture or bridge. Dentists advise pulling teeth as a last resort because they know that your natural teeth are the ones best suited for your mouth.

It's important to have the root canal procedure done quickly. The bacteria will travel down the canal to the root and into the jawbone. If this happens, the pain of your toothache will spread to your jaw. Even more important, the infection can cause your jawbone to deteriorate and weaken the structure that holds your teeth.

The best way to avoid root canal therapy is to take good daily care of your teeth to prevent the growth and spread of bacteria. Brushing and flossing are important.

Just as important are regular trips to the dentist, to check for the first sign of decay or cracks that could eventually lead to an abscessed tooth. In this case, an ounce of prevention really is worth a pound of cure!

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.
