What Is Root Canal Therapy?
A root canal is a dental procedure performed to remove infected or inflamed pulp tissue from inside a tooth. This process helps preserve the natural tooth structure while alleviating pain and preventing further complications. At Cosmo Dental Centre, our team provides comprehensive dental services in London, Ontario, guided by evidence-based protocols and patient-centred care. Contact our team today.

Signs You Might Need a Root Canal
Specific symptoms suggest that the soft tissue inside your tooth, known as the pulp, may be infected or damaged. Common signs include:
-
Persistent or throbbing toothache.
-
Sensitivity to hot or cold, even after the stimulus is removed.
-
Swelling or tenderness in nearby gums.
-
Discolouration or darkening of the tooth.
-
A recurring pimple or abscess on the gums.
If you experience any of these symptoms, it is essential to consult a dental professional promptly. Early diagnosis can prevent the need for more extensive treatments later. Get in touch with our team today.
What Makes a Dental Assessment Important Before Root Canal Treatment?
Before recommending root canal treatment, a thorough dental assessment helps identify the cause of discomfort and the condition of the affected tooth.
During an assessment, the dental team may review:
-
Tooth condition: The structure and health of the affected tooth are examined.
-
Surrounding tissues: The gums and nearby areas are evaluated for signs of related concerns.
-
Dental history: Previous treatments and oral health factors may be considered.
At Cosmo Dental Centre, advanced dental technology supports detailed examinations and root canal treatment planning for patients in London, Ontario. Contact us to arrange a dental evaluation with our team.
What to Expect During the Procedure
Root canal treatment involves several steps, typically carried out over one or two appointments:
Assessment and Diagnosis
The dentist conducts a clinical examination and may take X-rays to assess the extent of the infection.
Anaesthesia
Local anesthetic is administered to numb the area, ensuring the procedure is comfortable.
Access Opening
An opening is created in the tooth's crown to reach the pulp chamber.
Cleaning and Shaping
Infected tissue is removed using specialized instruments. The canals are then shaped and disinfected.
Filling the Canals
The cleaned canals are filled with a biocompatible material, usually gutta-percha, to seal them.
Temporary or Permanent Restoration
A temporary filling may be placed, but a crown is usually recommended to restore the tooth's strength and function.

Root Canal Retreatment: When It's Necessary
In some cases, a previously treated tooth may become painful or re-infected. Root canal retreatment involves reopening the tooth to remove the old filling, disinfecting the canals, and resealing the tooth. This process is typically considered when:
-
New decay exposes the filling material.
-
The tooth was not correctly restored with a crown.
-
An undetected canal was missed in the initial procedure.

Aftercare Tips
A root canal involves more than just removing diseased tissue. You must get professional assistance from your dentist to help safeguard your teeth. Consider the following suggestions:
-
Eat only soft foods for the first 24-48 hours after the treatment.
-
Brush your teeth twice daily.
-
Floss at least once a day.
-
Limit sugary foods and drinks.
-
Schedule regular dental checkups and cleanings.
