Endodontics is the area of dentistry concerned with the prevention, diagnosis and treatment of disorders of the dental pulp (the tooth’s soft core). Years ago, teeth with diseased or injured pulps were extracted. Today, endodontic treatment gives dentists a safe and effective means of saving teeth.
The pulp is a soft tissue that contains the nerves, arteries, veins and lymph vessels of a tooth. It lies within the dentin, the bone-like tissue that supports the enamel. Within the dentin, the pulp extends from the pulp chamber in the crown (the portion of the tooth visible above the gums) down to the tip of the root by way of the root canal. All teeth have only one pulp chamber, but teeth with more than one root with have more than one canal.
When the pulp is diseased or injured and unable to repair itself, the pulp dies. The most common cause of pulp death is a fracture or a deep cavity that exposes the pulp to saliva. The bacteria found in saliva causes infection inside the tooth. Left untreated, the infection eventually causes the pulp to die. Pus builds up at the root tip, forming an abscess that can destroy the supporting bone that surrounds the tooth.
If the damaged or diseased pulp is not removed, the tooth and surrounding tissues become infected. Pain and swelling may accompany the infection. Even in the absence of pain, certain by-products of a diseased pulp can injure the bone that anchors your tooth in the jaw. Without endodontic treatment, your tooth will eventually have to be removed.
Treatment usually requires from one to three appointments. During these treatments, your dentist or endodontist (a dentist who specializes in disorders of the pulp) removes the diseased pulp. The pulp chamber and root canal(s) of the tooth is then cleaned, shaped, filled and sealed to prevent recontamination of the root canal system.
The type of material used for the crown will depend on where the tooth is located in your mouth, the color of the tooth and the amount of natural tooth remaining. A front tooth that affects appearance, for instance, most likely will be restored with a porcelain or a porcelain-fused-to-metal crown. When a back tooth has been badly fractured or decayed, a gold or porcelain-fused-to-metal crown may be used. Your dentist will discuss these options with you.
The choice is yours but there are many disadvantages to losing a tooth. When a tooth is removed and no replaced, the teeth next to the empty space begins to shift from their normal position. This may cause teeth to become crooked or crowded, which then decreases chewing and biting efficiency. Crowded or crooked teeth may be more prone to dental disease because they are harder to keep clean than properly aligned teeth. As a result, other teeth may be lost if the missing tooth is not replaced.
A replacement tooth (an implant or a bridge) is usually more expensive than endodontic treatment and involves more extensive dental procedures on adjacent teeth. Endodontic treatment can safely and comfortably save a tooth that otherwise would have to be removed. In fact, root canal therapy is successful approximately 95% of the time. Remember, a healthy restored tooth is always better than an artificial one.
Your endodontically treated and restored tooth could last a lifetime, if you continue to care for your teeth and gums. As long as the root(s) of an endodontically treated tooth are properly nourished by the surrounding tissues, you tooth will remain healthy.
