A root canal is a procedure done in an effort to save an infected tooth or one that is severely decayed. When the pulp and nerve tissue inside a tooth is damaged, bacteria begin to form inside the pulp chamber.

Bacteria can lead to decay, and decay can cause infection and result in an abscessed tooth. The gum tissue around the tooth may become infected as well.

During a root canal procedure, your dentist removes nerve and pulp from inside the tooth, then seals and cleans it. Once this is done, you can return to your normal eating habits. Your tooth will be completely functional.

Root Canal Symptoms

Although it’s entirely possible that you’ll experience no symptoms whatsoever and will still need a root canal, you may experience any or all of the following symptoms if you have a tooth that requires the procedure:

• • You may experience a severe toothache, especially when you apply pressure on the tooth or use it to chew food
• • The affected tooth may become discolored
• • You may experience swelling in the gum tissue surrounding the tooth
• • The surrounding gum tissue may be painful or tender
• • You may notice extreme and prolonged sensitivity to hot and cold food and drinks
• • There may be a recurring pimple that appears on the gum tissue close to the affected tooth

A root canal procedure is an effective way to save a badly decayed tooth, which doesn’t need the nerve or pulp tissue to function. Usually, the procedure can be done in one or two office visits. Talk to your dentist for more information.
