Root Canal Therapy
Root canal treatment is necessary when the pulp (soft tissue inside your teeth containing blood vessels, nerves and connective tissue) becomes inflamed or diseased. During root canal treatment, your dentist or endodontist (a dentist who specializes in treating the insides of teeth) removes the diseased pulp. The pulp chamber and root canal(s) of the tooth are then cleaned and sealed. If the infected pulp is not removed, pain and swelling can result, and your tooth may have to be removed.
Causes of an infected pulp could include:
a deep cavity
repeated dental procedures
a cracked or broken tooth
injury to the tooth (even if there’s not a visible crack or chip)
If you continue to care for your teeth and gums your restored tooth could last a lifetime. However, regular checkups are necessary; a tooth without its nerve can still develop cavities or gum disease. Most of the time, a root canal is a relatively simple procedure with little or no discomfort involving one to three visits. Best of all, it can save your tooth and your smile.
How does endodontic treatment save the tooth?
During root canal treatment, the inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned and disinfected, then filled and sealed with a rubber-like material called gutta-percha. Afterwards, the tooth is restored with a crown or filling for protection. After restoration, the tooth continues to function like any other tooth.
Contrary to jokes about the matter, modern root canal treatment is very similar to having a routine filling and usually can be completed in one or two appointments, depending on the condition of your tooth and your personal circumstances. You can expect a comfortable experience during and after your appointment. Saving the natural tooth with root canal treatment has many advantages:Efficient chewing
- Normal biting force and sensation
- Natural appearance
- Protects other teeth from excessive wear or strain
Endodontic treatment helps you maintain your natural smile, continue eating the foods you love and limits the need for ongoing dental work. With proper care, most teeth that have had root canal treatment can last as long as other natural teeth and often for a lifetime.
Root Canal Therapy
Occasionally, a nonsurgical root canal procedure alone cannot save your tooth and your endodontist will recommend surgery. Endodontic surgery can be used to locate small fractures or hidden canals that weren't detected on x-rays or during previous treatment. Surgery may also be needed to remove calcium deposits in root canals, or to treat damaged root surfaces or the surrounding bone of the tooth. To learn more about endodontic surgery, talk to an endodontist in your area.
There are many surgical procedures that can be performed to save a tooth. The most common is called an apicoectomy, or root-end resection, which is occasionally needed when inflammation or infection persists in the bony area around the end of your tooth after a root canal procedure. In this microsurgical procedure, the endodontist opens the gum tissue near the tooth to see the underlying bone and to remove any inflamed or infected tissue. The very end of the root is also removed. A small filling may be placed to seal the end of the root canal and few stitches or sutures are placed to help the tissue heal. Over a period of months, the bone heals around the end of the root. Local anesthetics make the procedure comfortable, and most patients return to their normal activities the next day. Postsurgical discomfort is generally mild.
