Root Canal Therapy in Thornhill
Overview
A root canal procedure is a highly effective treatment designed to save a severely damaged or infected tooth from extraction. When decay, injury, or infection reaches the inner pulp of a tooth, root canal therapy removes the affected tissue, alleviates pain, and preserves your natural tooth structure.
Signs you may need a Root Canal
If you’re experiencing any of the following symptoms, it’s important to see our Thornhill dentist as soon as possible:
✔ Swollen or tender gums around a tooth
✔ Pain while chewing or biting downt
✔ Sensitivity to hot or cold foods and drinks
✔ Darkening or discoloration of a tooth
Seeking early treatment can sometimes prevent the need for a root canal by allowing for a more minor intervention, such as a dental filling. If left untreated, an infected tooth can worsen and spread to surrounding tissues and bone, leading to more serious complications.


Common causes of Root Canal issues
A root canal may be necessary due to:
✔ Tooth Decay – When a cavity is left untreated, bacteria can penetrate deep into the tooth, causing infection and inflammation. If the damage is too severe for a filling, a root canal may be required.
✔ Chipped, Cracked, or Broken Teeth – A significant break or fracture can expose the inner pulp of the tooth, leading to pain and infection. In these cases, endodontic treatment helps restore and protect the tooth.
✔ Dental Trauma or Injury – A blow to the mouth, even if the tooth doesn’t break, can damage the pulp inside. This type of injury may require root canal therapy to prevent long-term complications.
What happens during a Root Canal procedure?
A root canal is a multi-step process designed to remove infection, relieve pain, and restore the tooth’s integrity:
1
A rubber dam is placed around the tooth to keep it dry and free from bacteria, and a local anesthetic is administered for a pain-free experience.
2
A small opening is made in the tooth, allowing the dentist to carefully remove the infected pulp. The root canals are then cleaned, disinfected, and shaped.
3
The empty space inside the tooth is sealed with a biocompatible material called gutta-percha to prevent reinfection.
4
To protect and strengthen the tooth, a custom dental crown is placed over it. The type of crown used will depend on the patient’s preferences and needs, and our Thornhill dentist will discuss the best options with you.
Root canal therapy has a high success rate, and with proper care, a treated tooth can last a lifetime.
