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.

The Endodontist and a Successful Root Canal Treatment

Many international scientific studies demonstrate that root canal treatment is generally successful and provides an excellent long-term prognosis when the dental surgery is properly performed utilizing sound biological and mechanical concepts. As with any clinical situation, there are factors that must be considered when discussing root canal procedure outcomes with your dentist or endodontist:

1. Root canal treatment has not always been as successful as it is today. Fortunately, the guiding principles of modern endodontics can now be utilized to deliver very predictable results over a patient's lifetime. Some of these principles were unknown or misunderstood in the past and, consequently, many teeth have had endodontics treatment based on concepts, techniques, and materials that are not considered optimal by today's standards. Even so, some of these teeth have given, and will continue to give, additional years of good service. In other instances, previously treated teeth exhibit bacterial leakage that may or may not be accompanied by clinical symptoms. Failing endodontically treated teeth can generally be successfully retreated by an endodontist using modern biological concepts, technologies, and techniques.
2. Root canal treatment can be successful even if a tooth is severely damaged by decay, trauma, or other destructive events. In cases such as this, it may be necessary to reinforce the tooth by placing a post into the root before a crown can be placed. In these situations, the root canal dentist must weigh risks versus benefits during the treatment planning process.
3. The success of root canal treatment is greatly enhanced when the tooth receives a protective restoration after completion of the treatment. When a protective crown is not placed, the root canal filling may leak or the tooth may develop additional decay or even fracture. Once a root fracture has occurred, there is generally no predictable treatment or dental surgery to save the tooth.
4. For an endodontic treatment to be successful, the periodontal supporting structures of the tooth must be healthy or capable of being returned to a state of health with periodontal treatment. Other specialty consultations may also be necessary depending on the findings in a particular situation.
5. To insure that root canal treatment is working, the particular tooth should be evaluated over time. Teeth are subject to enormous shifts in temperature (such as hot coffee vs. ice cream), tremendous mechanical loads (in pounds per square inch), and constant exposure to the bacteria in saliva. Periodic re-evaluation allows the dentist to examine the results of past treatments and to intervene early if new damage or breakdown is occurring.

As with any human endeavor, there are certain clinical situations in which dental surgery does not work even with the best efforts that modern dentistry can offer. Fortunately, these cases are infrequent and, if they occur, many of the teeth can be successfully retreated by an endodontist. A root canal procedure, when appropriately planned and well-performed by your dentist or endodontist, is the most cost-effective and predictable treatment alternative in most clinical situations.
