To better understand Root Canal Therapy it helps to have a little background knowledge of a tooth’s structure. Our teeth are layered, an example is shown down below. As you can see the pulp chambers go all the way down to the root of the tooth in narrow passage ways or “root canals”. Within these root canals and pulp chambers there are blood vessels, nerves and other tissues that nourish the tooth and carry sensory signals back to the brain. Human teeth have one to four canals, teeth in the front having the least and increasing the further back you go.
Root Canal Therapy or Endodontic Therapy is done in order to save a tooth. Often times it is an infection, traumatic injury or diseased inner tooth that leads to having root canal therapy. When an infection spreads within a tooth it’s the pulp chamber that is affected and eventually spreads down to the roots. When your tooth suffers traumatic injury or disease, damage is also done to the pulp which can lead to similar problems for your tooth.
Root Canal Therapy works by removing the pulp and nerve from the root canal. The dentist drills into the pulp chamber and removes the pulp and nerve using a long needle-shaped drill. Once everything is removed and disinfected the dentist then fills the chamber, canals and opening made to access the inner tooth. The tooth still looks the same from the exterior however it is now considered ‘dead’. There are no longer any nerves thus feeling left in that tooth. Any pain associated with that tooth should no longer be present after the procedure.
