A root canal treatment is needed when the soft tissue inside the root of a tooth, known as the pulp, experiences inflammation or infection. Inflammation or infection can occur as a result of several things, including severe decay that burrows into the deeper reaches of a tooth, repeated dental procedures, or the presence of a chip or crack. A trauma or injury to a tooth may result in pulpal damage that is not visible to the naked eye. However, if the tooth remains untreated, pain or sensitivity may occur and an abscess could develop. Symptoms one may experience prior to requiring root canal therapy include persistent sensitivity to heat or cold and tooth discoloration. The tooth may also be sensitive to chewing and touch. Other warning signs include inflammation and sensitivity in the lymph nodes or nearby bone and gum tissues. Sometimes, a patient may not experience any symptoms, but still be in need of endodontic treatment.

 

Under a microscope, your endodontist will remove the inflamed or infected pulp. The canal will be thoroughly cleansed and carefully reshaped. Afterwards, the canals are filled and the small access hole sealed with a temporary filling material. Within two to five weeks, you will need to see your general dentist for a permanent restoration (filling or crown) of the tooth. This will protect the tooth from fracture and restore it to its proper function. Nowadays, endodontists perform root canal treatments with advanced equipment and techniques, making them faster and far more comfortable than in the past.
