Root Canal Therapy

root-canal-therapyOur dental structure is complex, and a lot can happen below what you see on the surface. Under your exposed teeth are roots and root canals, which contain nerves, blood vessels and connected tissues. Keeping your root canals fit is just as vital as keeping your teeth’s surfaces and gums strong. Just like a tooth can develop a cavity, a root canal can become septic and require dental treatment. If the infected tissue is not treated, it breaks down and bacteria can cause a sore, or infection of the mouth, face, jaw, or throat.

If left untreated, an infected root canal, and consequent abscessed tooth, can cause one or more of the following:

  • Swelling that can spread to other areas of mouth.
  • Bone loss around the root tip.

With a simple procedure called root canal therapy (RCT) Dr. Marze will clean and seal the entire root canal to prevent future infections in the nerve tissue.

Root Canal Symptoms

The root canals of your teeth contain blood vessels, nerve fibers and soft lymph tissues. These tissues can become impaired due to a deep cavity, repeated dental work on the same tooth, a cracked tooth. Root canal therapy (RCT) is often the best choice to release your pain and avoid losing the tooth completely. You may need a root canal therapy if you experience one or more of the following root canal symptoms listed below.

Common Root Canal Symptoms

  • Strong, sustained throbbing pain in tooth.
  • Hurts when chewing.
  • Hurts to consume cold or hot food or drink.
  • Discolored tooth.
  • Swollen and sensitive gums.

Root Canal Therapy (RCT) Procedure

Root canal therapy (RCT) is usually the best way to clear infections in the root canal. During the root canal procedure, we will clean out the infected root canal and then fill it to stop future infections.


Depending on the infection of your root canal spreads, we may perform a partial root canal. This procedure, called a pulpectomy, will release pain and allow time for antibiotics to reduce the infection. At an initial dentist appointment, we will manage antibiotics to lessen the infection. At a second appointment, we will take out the infected pulp, and clean and fill the infected canal.


In certain cases, with extreme infection beyond the root tip, we may suggest an Apicoectomy in order to save the tooth. We will remove a portion of the root tip as well as the infection in your dental roots. Once we remove the infected tissue and cleans the entire area, the canal is filled with biocompatible material and “Gutta Percha”, which is a rubber-like material that covers your tooth from bacteria and reinfection.
