Root Canals
Root canal treatment, also referred to as root canal therapy or endodontic therapy, is used to save an infected or damaged tooth and avoid having it removed. A root canal becomes necessary when a neglected cavity reaches all the way to the pulp at the center of the tooth, causing the pulp to become infected. Regular cleanings and checkups detect and prevent problems early on.
Trauma can also cause deep damage to the nerve of a tooth. Once this occurs, the pulp becomes infected and begins to eat away at the surrounding bone (this is called an abscess). By the time the pulp is infected it must be treated and cannot heal on its own. It can even weaken the entire immune system, making it very dangerous and painful.
Symptoms of infected pulp may include sensitivity to hot/cold or sweets, pain, swelling, pain with biting or pressure, and a bad taste in the mouth. Sometimes, however, there are no symptoms, and you are unaware of any problem until a checkup.
A root canal is performed to clean out the infected tooth pulp and disinfect the canals of the tooth. The only other treatment would be to extract the tooth. Once the infection is resolved, the canal(s) is filled to prevent any further infection. Crowns are usually recommended to cover and restore a tooth after root canal therapy.
Frequently Asked Questions about Root Canals
Is a root canal painful?
Modern dentistry has made root canals much more comfortable than they once were. Local anesthesia is used to numb the area around the tooth, so you shouldn't feel any pain during the procedure. Afterwards, you may experience some mild discomfort or tenderness for a few days, but this can be managed with over-the-counter pain relievers.
Will I lose my tooth?
No, a root canal is actually performed to save your tooth! By removing the infected pulp and cleaning the inside of the tooth, the root canal prevents further infection and allows the tooth to remain functional.

How long does the procedure take?
The length of a root canal can vary depending on the complexity of the case. Typically, it can be completed in one or two appointments at the dentist's office.
Do I need a root canal if my tooth doesn't hurt?
Not always. Sometimes the signs of an infected pulp can be subtle, such as sensitivity to hot or cold. However, even if you're not experiencing pain, a root canal might be necessary to prevent future problems like swelling, abscesses, and bone loss. Your dentist can diagnose an infected tooth and recommend the best course of treatment.
What happens after a root canal?
After a root canal, the inside of the tooth will be filled with a special material. In most cases, a crown will also be placed on the tooth to protect it and restore its full functionality.
How long do teeth last after a root canal?
With proper care, a tooth that has undergone a root canal can last for many years, just like any other tooth. Brushing, flossing, and attending regular dental checkups are essential for maintaining good oral health and the longevity of your treated tooth.
