We have a lot of information to share with you about this tooth-saving procedure, but here's the
main takeaway: Root canal treatment is nothing to fear. Really!
Why Is It Called "Root Canal"?
The term "root canal" actually has two meanings. It is commonly used to describe a procedure for
treating inflammation or a bacterial infection deep inside a tooth, as in "you need a root canal." And it
is also the name of a part of the tooth itself: the narrow, hollow channel that runs from the tip of the
root to a central space in the centre of the tooth called the pulp chamber.
These inner tooth spaces house the nerves and blood vessels that nourished the tooth as it was
growing. In adults, these tissues aren't really needed — but they do allow the tooth to feel pain, hot,
cold and other stimuli. A front tooth that has one root will have one main canal.
A molar, which has multiple roots, will have more than one canal. A main root canal can have several
"accessory" canals branching off of it.
The tissues within the pulp chamber and canals can become inflamed or infected by bacteria; this
sometimes happens when a cavity is not treated in a timely manner, or when a tooth is injured. The
inflamed tissues often cause pain inside the tooth. The purpose of root canal treatment performed by
an Endodontist is to relieve the pain and stop the infection.
It's possible to have a root canal problem without pain. But if your dentist has
identified a root canal infection, you need to get it taken care of — right away. If you
don't, sooner or later you will likely lose the tooth. Without treatment, the infection
could get worse.

tissues within the pulp chamber and canals can become infected from the same bacteria that caused the
tooth decay. A root canal in a molar is more difficult because of longer roots and multiple canals, which
often have accessory canals. Specially designed instruments are used to remove the diseased pulp
tissue. The canals are filled with gutta-percha which seals them up and prevents bacteria from re-
entering the tooth. A filling material seals the tooth until the final crown is placed. A crown is used to
protect the tooth from future fracture or damage.
What Happens During a Root Canal Procedure?
The goal of root canal treatment is to remove all diseased tissue from inside the tooth, and to seal the
tooth against re-infection.
Local anaesthesia is used during the treatment hence you will not feel the area worked on due to
numbness. In order to reach the infection, a small access hole will be drilled in the tooth — through
the biting surface of a back tooth or the back side of a front tooth. Specially designed instruments will
be used to remove the tooth's diseased pulp.
An added bonus is that once this tissue is gone, the tooth will no longer be able to feel pain.
Next, the canals will be flushed with antibacterial solutions, and then filled completely with a rubberlike
biocompatible material called gutta-percha and then the access hole will receive a filling. These
fillings and sealers will prevent bacteria from once again entering the tooth.
What Happens After a Root Canal Procedure?
It is normal to experience some minor soreness for a few days after a root-canal procedure — but no
more than you would expect from an ordinary filling. Any discomfort can usually be managed with
over-the-counter medications such as ibuprofen or specific prescription issued by the dentist if you
have a medical condition or history.
You will need to return to the dentist in a few weeks to receive a more permanent filling for the access
Most often, a full-coverage dental crown is recommended to completely seal the tooth and prevent it
from fracturing under stress. This is especially helpful in back molars, which receive the most biting
force. When properly restored, a root-canal-treated tooth can last for a lifetime.
Root canal treatment is a highly successful procedure that has enabled millions of people around the
world to keep teeth that would otherwise have been lost. It has saved a lot of investment in tooth-
replacement costs. Wouldn't you rather have a root canal?
