Root Canal Therapy in

Man with gray hair and beard smilingRoot canal therapy (also known as “root canal treatment,” a “pulpectomy,” “endodontic treatment” or, simply, a “root canal”) involves the cleaning out and refilling of the root canal.

The tooth can be broken down into two sections:

  • The crown is the visible portion of the tooth and is made of a tough enamel exterior and a dentin interior.
  • The root contains one or multiple canals that are filled with pulp tissue. This tissue or pulp is made up of nerves and blood vessels which are responsible for reporting stimulus to the brain as well as providing the nutrients necessary for the construction and maintenance of healthy teeth.

When this pulp gets infected because bacteria from a decaying tooth have entered the canal through a deep cavity, root canal therapy is made necessary. Severe tooth decay is not always the reason for root canal therapy (perhaps severe trauma to the mouth has damaged the root systems of one or more teeth), but more often than not, it is.

Infected pulp will soon become inflamed if allowed to go without treatment, causing sharp pain, the death of the tooth, and potentially a rather nasty and painful infection. In extreme circumstances, the infected canal can cause the tooth to weaken to the point of breaking and do further damage to the surrounding bone. Dr. Clark will work with you to avoid these more severe consequences where at all possible.

Cleaning Out the Canal

Alleviating the pain and saving the tooth requires the removal of any infected pulp tissue and the cleaning and subsequent disinfection of the canal. To do this, Dr. Clark will make a small hole in the crown of the tooth to provide access to the canal(s). A very fine file-like instrument is then used to clean the pulp out of the root and enlarge the canal. Irrigating solutions are also employed to make sure that none of the infected material remains.

Filling the Canal

The clean and disinfected opening is then filled with a durable and biocompatible (meaning it is non-toxic and promotes healthy tissue recovery) material that seals off the root canal.

Covering the Canal

At this point, all that remains is to restore the tooth through the use of some form of cap. Depending on the strength and amount of remaining tooth, Dr. Clark may recommend a filling or a crown. If the remaining portion of the tooth is too weak to support a crown safely, metal posts can be inserted which will add to the integrity of the tooth.
