Root Canal Therapy

What is a root canal?

Underneath your tooth’s outer enamel and within the dentin is an area of soft tissue called the pulp, which carries the tooth’s nerves, veins, arteries and lymph vessels. Root canals are very small, thin divisions that branch off from the top pulp chamber down to the tip of the root. A tooth has at least one root canal.

Why do I feel pain?

When the pulp becomes infected due to a deep cavity or fracture that allows bacteria to seep in, or injury due to trauma, it can die. Pain in the tooth is commonly felt when biting down, chewing on it and applying hot or cold foods and drinks.

Why do I need root canal therapy?

Because the tooth will not heal by itself. Without treatment, the infection will spread, bone around the tooth will begin to degenerate, and the tooth may fall-out. Pain usually worsens until one is forced to seek emergency dental attention. The only alternative is usually extraction of the tooth, which can cause surrounding teeth to shift crookedly, resulting in a bad bite. Though an extraction is less expensive, the space left behind will require a dental implant or a bridge, which can be more expensive than root canal therapy. If you have the choice, it’s always best to keep your original teeth.

What is involved in root canal therapy?

First, you will probably be given a local anesthetic to numb the area. A rubber sheet is then placed around the tooth to isolate it. Next, an openning is made into the pulp chamber, which, along with any infected root canal, is cleaned of all diseased pulp and reshaped. Medication may be inserted into the area to fight bacteria. Depending on the condition of the tooth, the crown may then be sealed temporarily to guard against recontamination, or the tooth may be left open to drain. If you’re given a temporary filling, usually on the next visit it’s removed and the pulp chamber and canal(s) are filled. If the tooth is still weak, a metal post may be inserted above the canal filling to reinforce the tooth. Once filled, the area is permanently sealed. Finally, a gold or porcelain crown is normally placed over the tooth to strengthen its structure and improve appearance.

What are the risks and complications?

More than 95 percent of root canal treatments are successful. However, sometimes a case needs to be redone due to diseased canal offshoots that went unnoticed or the fracturing of a canal filing instrument used-both of which rarely occur. Occasionally, a root canal therapy will fail altogether, marked by a return of pain.

What happens after treatment?

Natural tissue inflammation may cause discomfort for a few days, which can be controlled by an over-the-counter analgesic. A follow-up exam can monitor tissue healing. From this point on, brush and floss regularly, avoid chewing hard foods on the treated tooth, and see your dentist regularly.
