How Long Does A Root Canal Last?

Posted on January 11, 2022

In the center of every tooth lies a chamber. Inside this space, there is a nerve, an artery, and a vein. This living tissue is called the pulp of the tooth. If decay, trauma, cracks, or fractures violate the sanctity of the pulp chamber the living tissue will start to die (necrose). As the organic tissue starts to break down first we see inflammation and then we see the infection. As a patient, you will feel a dull ache at first. Then the pain becomes more severe, pounding at times. The pain increases when we lie down if we eat something hard or hot. There can be a bump in our gum or even swelling in our face. This is the classic toothache with subsequent dental abscess formation. So what are we to do? There are two options. Extract the tooth or perform root canal therapy.

The Root Canal Procedure

  1. Local anesthesia is given at the infected tooth and a rubber dam is placed to isolate the tooth. 
  2. A small opening is made into the tooth.
  3. The endodontist (a dentist specializing in root canal therapy) will use tiny instruments to remove the infected tissue in the chamber and canals of the tooth.
  4. The chamber is sterilized and filled with an inert material (gutta percha) so that re-infection will not occur. 
  5. The tooth will in most cases be restored with a core and beautiful porcelain crown. 

How Long Does it Last?: Root Canal Success Rates

487,476 root canal treatments were part of the following study:

Success rates:

  • 98% after one year
  • 92% after five years
  • 86% after ten years
  • Molar root canal therapies were significantly more successful when performed by an endodontic specialist than a general dentist. 

Factors that Affect Success

  1. Prompt treatment at first signs of a toothache to stop the infection from spreading. 
  2. Quality treatment by an endodontist (root canal specialist) to ensure that all canals are filled and that there is no contamination of saliva.
  3. Proper core and crown placement to restore the tooth to form and function
  4. Tooth location: Front teeth are easier to operate on as there is only one canal and they are not subjected to the occlusal forces that the back teeth must absorb. 
  5. Age of patient: As one grows older, teeth become more brittle and can fracture more easily after treatment. Canals may be more calcified and more difficult to prepare. 
  6. Other factors:
    •   Habits such as grinding teeth (bruxism) and clenching
    •   Trauma from sports, falling and other accidents
    •   Systemic diseases such as diabetes
    •   Radiation
    •   Medications
