Tooth cracks, trauma, and decay can sometimes cause infection and irritation of the dental, resulting in the need for a root canal.


Root Canal is a treatment used to save and repair a tooth that is badly decayed and infected. It is a conservative procedure used to save a natural tooth to avoid tooth extraction for dental implant or bridge.

“Root canal” is the term used to describe the natural cavity within the center of the tooth. Below the hard exterior surface of the tooth lies the pulp or pulp chamber which is pulp the soft area within the root canal that is made of up of cells and connective tissue.


Sometimes no symptoms are present; however, the number one symptom of an infection of the root is pain. Some signs that you may need a root canal include:

  •     Severe toothache pain upon chewing or application of pressure
  •     Prolonged sensitivity/pain to hot or cold temperatures (after the hot or cold has been removed)
  •     Discoloration (a darkening) of the tooth
  •     Swelling and tenderness in the nearby gums
  •     A persistent or recurring drainage on the gums

Your doctor will assess your situation during a consultation to see if root canal therapy is right for you


The root canal involves the removal of the infested dental pulp and sealing of the root canal. It consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root.

During a root canal procedure, the nerve and pulp tissue are removed and the inside of the tooth is cleaned and sealed.  Without treatment, the tissue around the tooth could become infected and cause an abscess.

This generally involves the use of local anesthesia (or sedative anesthesia for sensitive person) because of the pulp receives nutrition through the blood vessels, and sensory nerves carry signals back to the brain. You will feel pain when the pulp is infected.



Modern techniques have eliminated a lot of the discomfort that has previously been associated with root canals.
