Root Canal Therapy in Kanata
Saving Your Natural Tooth with Root Canal Treatment
Root canal therapy is a restorative dental procedure used to save a tooth that has become infected, severely decayed, cracked, or damaged. At March Dental in Kanata, we provide root canal treatment to relieve pain, remove infection, and preserve your natural tooth whenever possible. Saving your own tooth is often the best long-term option for maintaining your bite, chewing ability, and overall oral health.
Inside every tooth is a soft tissue called the pulp, which contains nerves and blood vessels. When decay, large fillings, cracks, repeated dental procedures, or trauma affect the nerve tissue inside the tooth, the pulp can become inflamed or infected. Root canal therapy removes the damaged pulp, cleans and disinfects the space inside the tooth, and seals it to help prevent further infection.
Many people associate root canals with discomfort, but modern techniques and local anesthesia make treatment much more comfortable than most patients expect. In many cases, the pain patients experience comes from the infection itself, not the procedure. Root canal therapy is designed to remove the source of that pain and help return the tooth to a comfortable, functional state.
March Dental provides root canal therapy for patients in Kanata, Stittsville, Carp, Constance Bay, Arnprior, Smiths Falls, Ottawa, and surrounding communities.
When Is a Root Canal Needed?
A root canal may be needed when the pulp inside the tooth becomes infected or inflamed. This can happen when tooth decay reaches the inner chamber of the tooth, when an infection or abscess develops at the root tip, when a tooth is injured, or when a crack extends toward the nerve chamber. Large fillings can also weaken a tooth over time and place the nerve at greater risk.
Common signs that you may need root canal treatment include severe toothache, prolonged sensitivity to hot or cold, pain when chewing, swelling around the gums or jaw, a pimple-like bump on the gums, tooth discolouration, tenderness, or an abscess. Sometimes, however, a tooth may need root canal therapy even when there are few or no obvious symptoms. This is why regular dental exams and X-rays are important.
Your Kanata dentist will carefully examine the tooth, review your symptoms, and take X-rays when necessary to determine whether root canal therapy is the most appropriate treatment.
What Happens During Root Canal Therapy?
The goal of root canal treatment is to remove the infected or damaged pulp while preserving the outer structure of the tooth. The procedure begins by numbing the area to keep you comfortable. A rubber dam may be placed over the tooth to keep it dry, clean, and free from saliva during treatment.
Once the tooth is numb and isolated, a small opening is made in the top of the tooth. Your dentist then uses specialized instruments to remove the pulp, nerve tissue, bacteria, and any decay from inside the tooth. The root canals are carefully cleaned, shaped, and disinfected with medicated solutions to reduce bacteria and prepare the space for sealing.
After the canals have been thoroughly cleaned, they are filled with a bioinert dental material and sealed. Root canal therapy may be completed in one visit or over multiple visits depending on the tooth, the severity of infection, and the treatment required. If more than one appointment is needed, a temporary filling may be placed to protect the tooth between visits.
Why a Crown Is Often Recommended After a Root Canal
After root canal therapy, the tooth may be more vulnerable to fracture, especially if it is a back tooth used for chewing or if it had a large cavity, crack, or filling before treatment. For this reason, a dental crown is often recommended after root canal treatment.
A crown covers and protects the visible portion of the tooth, helping restore strength, function, and appearance. Root canal therapy removes the infection and saves the tooth, while the crown helps protect that tooth from breaking under everyday chewing pressure. Together, these treatments can improve the long-term prognosis of the tooth and help return it to comfortable function.
Your dentist will explain whether a crown is recommended based on the tooth’s location, remaining structure, bite pressure, and overall condition.
Why Saving the Tooth Matters
Some patients wonder whether it would be easier to simply remove a painful tooth instead of having root canal therapy. In some cases, extraction may be necessary, but when a tooth can be saved, root canal treatment is often the preferred option.
Removing a tooth can lead to future oral health concerns. Nearby teeth may shift into the open space, your bite may change, chewing may become more difficult, and bone loss can occur in the area where the tooth is missing. Tooth loss may also create the need for additional treatment later, such as a dental implant, fixed bridge, or denture.
By saving your natural tooth, root canal therapy helps preserve your bite, maintain chewing function, and reduce the need for more complex tooth replacement treatment in the future.
Caring for a Tooth After Root Canal Therapy
Root canal therapy is normally highly effective, and many treated teeth can last for many years with proper care. However, a root canal-treated tooth still needs regular maintenance. A common misconception is that a tooth cannot get decay after a root canal because the nerve has been removed. This is not true.
The remaining tooth structure can still develop cavities, especially around fillings, crowns, or the gumline. Because the nerve has been removed, decay may progress without the same pain signals a natural tooth would normally send. Regular dental exams and X-rays are important so your dentist can monitor the treated tooth and detect concerns early.
Occasionally, a root canal-treated tooth may need retreatment if a new infection develops. Good brushing, flossing, fluoride use when recommended, and regular visits to March Dental can help protect the longevity of your treatment.

In many cases, yes. Teeth that have had root canal treatment, especially molars, often benefit from a dental crown to restore strength and reduce the risk of fracture.
