Millions of teeth are treated each year with root canals. A root canal is necessary if the pulp, or soft tissue inside the root canal of the tooth becomes inflamed. Inflammation is a sign of infection and can be caused by numerous conditions: a chip or crack in the tooth, numerous dental procedures on the same tooth, deep decay, or injury to the tooth. When inflammation is left untreated an abscess can form causing pain.

Signs of Needing a Root Canal

Below are the main signs indicating a root canal may be necessary. It is important to contact your dentist right away when symptoms persist. This can allow the dentist to catch the issue in the early stage and treat it before the infection becomes worse.

• Prolonged sensitivity to heat and/or cold
• Pain
• Tender when chewing or area is touched
• Tooth discoloration
• Swelling, tenderness and drainage in the lymph nodes

What is Involved with a Root Canal?

Your dentist will take x-rays of the infected tooth and conduct an exam. An anesthetic is administered and, once the tooth is numb an opening is made in the crown of the tooth and then small instruments are used to clean out the root canals and pulp chambers. The root canals are then filled using a biocompatible material. A crown is placed on top of the tooth to close the opening.

Is Special Care Required?

Before the permanent crown is placed, it is advised to try and refrain from chewing or biting onto that tooth. Once the permanent crown is placed, then practicing good oral hygiene is all that is required. Making sure you keep up on your dental visits will allow your dentist to check on the crown and make sure there are no issues with it.
