Root Canals: Everything You Ever Wanted to Know

Why are root canals done?

Root canal therapy is required when the nerve of the tooth becomes irreversibly damaged. This damage can occur from decay, trauma, or a crack in the tooth.

What is a common root canal symptom?

Pain, swelling, and sensitivity to hot or cold. Another indication of nerve damage is the tooth becoming darker in color. Sometimes, it can only be diagnosed with an x-ray or other tests by an endodontist.

What is done during a root canal procedure?

The purpose of root canal therapy is to clean out the infected tooth pulp tissue within the roots. After all the nerve has been removed, the canals are filled with a sealer.

How long will the procedure take?

Generally, root canals take one or two appointments for a front tooth (anterior), and two or three appointments for a back tooth (posterior). A tooth can have from one to four roots; all of the roots must be treated. Difficult cases may require even more visits.

Will the tooth need any more work after the treatment is finished?

Yes, the tooth will require a permanent restoration. This could range from a simple filling to a large build-up with posts and pins. The tooth is more brittle after a root canal treatment and therefore is more susceptible to fracture. If the filling is large, the tooth may need a crown as well. A crown protects the tooth from breaking.

Isn't it simpler to take out the tooth?

It may seem simpler to have the damaged tooth removed; however, it is really much healthier and more economical to save it. If the extracted tooth is not replaced, the teeth next to it can drift into the empty space. Replacing an extracted tooth involves either expensive bridgework or a partial denture.

Will the root canal procedure hurt?

During the actual treatment, your tooth will be numb as it would be for simply filling a cavity. The treatment is usually started because the tooth is sensitive; it may take a day or two for the tooth to get back to normal. Generally a mild painkiller is enough to keep you comfortable during this time. If something stronger is needed, your endodontist will prescribe it. If the tooth is badly infected, an antibiotic may be needed as well.

How much will it cost?

The cost of root canal treatment and therapy varies with the number of canals which need to be treated. There will be a separate charge for the restoration, depending on the extent of the procedure. Your dentist will be glad to discuss the charges with you for all the expected treatment.

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!
