Many of us shudder when we are told by the dentist that we need a root canal. To clear up the confusion, here are the most commonly asked questions regarding this common treatment.  

What is a root canal?
“Root canal” is the term used to describe the natural cavity within the center of the tooth. The pulp or pulp chamber is the soft area within the root canal. The tooth’s nerve lies within the root canal. 

What is the process involved?
A root canal is a treatment used to repair and save a tooth that is badly decayed or becomes infected. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed. Without treatment, the tissue surrounding the tooth will become infected and abscesses may form. 

What is the recovery after a root canal?
For the first few days following the completion of a root canal, the tooth may feel sensitive due to natural tissue inflammation, especially if there was pain or infection before the procedure. This sensitivity or discomfort usually can be controlled with over-the-counter pain medications such as ibuprofen. Most patients can return to their normal activities the next day. 

How to avoid a root canal?
Following good oral hygiene practices (brushing twice a day, flossing at least once a day, and scheduling regular dental visits) may reduce the need for a root canal procedure. Trauma resulting from a sports-related injury can be reduced by wearing a mouth guard.
