Root Canal Treatment Explained: What You Need to Know
Root canal treatment has an undeserved reputation for being something to dread. In reality, modern root canal therapy is a routine procedure that relieves pain and saves teeth that might otherwise need to be extracted. At Shine Dental in Newington, Dr. Jin-Ho Cho has over 35 years of experience performing root canal treatments and helping patients understand exactly what to expect.
What Is Root Canal Treatment?
A root canal — more precisely called endodontic treatment — involves removing the infected or inflamed pulp tissue from inside a tooth, cleaning and shaping the root canals, and sealing them to prevent reinfection. The tooth is then restored with a filling or crown.
The pulp is the soft tissue inside the tooth that contains nerves, blood vessels, and connective tissue. While the pulp is vital during tooth development, a fully developed tooth can survive without it because the surrounding tissues continue to nourish it.
When Is Root Canal Treatment Needed?
Root canal treatment may be recommended when the pulp inside a tooth becomes infected or irreversibly inflamed. Common causes include:
- Deep decay — a cavity that has progressed to the inner pulp
- Repeated dental procedures — multiple treatments on the same tooth can stress the pulp
- Cracks or chips — damage that exposes the pulp to bacteria
- Trauma — a blow to the tooth, even if there is no visible crack
- Advanced gum disease — infection that reaches the root
Signs You May Need a Root Canal
- Persistent or severe toothache, especially when biting or chewing
- Prolonged sensitivity to hot or cold that lingers after the stimulus is removed
- Darkening or discolouration of a tooth
- Swelling or tenderness in nearby gums
- A pimple-like bump (fistula) on the gums near the affected tooth
If you experience any of these symptoms, it is important to seek dental care promptly. Delaying treatment can allow infection to spread and may result in tooth loss.
The Root Canal Procedure at Shine Dental
Here is what you can expect during root canal treatment at our Newington clinic:
Step 1: Diagnosis Dr. Cho will examine the tooth, take X-rays, and may perform tests to confirm whether root canal treatment is necessary.
Step 2: Anaesthesia The area is numbed with local anaesthesia so you remain comfortable throughout the procedure.
Step 3: Access and Cleaning A small opening is made in the crown of the tooth to access the pulp chamber. The infected pulp is carefully removed, and the canals are cleaned, shaped, and disinfected.
Step 4: Filling the Canals The cleaned canals are filled with a biocompatible material called gutta-percha and sealed.
Step 5: Restoration In most cases, a crown is placed over the treated tooth to protect it and restore its full function. This may be done at a follow-up appointment.
Recovery and Aftercare
Recovery from root canal treatment is typically straightforward:
- Mild discomfort for a few days is normal and can usually be managed with over-the-counter pain relief
- Avoid chewing on the treated tooth until the permanent restoration (crown) is placed
- Maintain normal oral hygiene — brush and floss as usual, being gentle around the treated area
- Attend follow-up appointments to ensure proper healing and to have the final crown fitted
Root Canal vs. Extraction
Some patients wonder whether it would be simpler to just extract the tooth. While extraction is sometimes necessary, preserving your natural tooth through root canal treatment offers significant advantages:
- Maintains your natural bite and chewing ability
- Prevents adjacent teeth from shifting
- Avoids the need for an implant or bridge to replace the missing tooth
- Preserves jawbone in the area
If extraction is the better option in your case, Dr. Cho will discuss tooth replacement solutions such as dental implants or dental bridges.

Frequently Asked Questions
Is root canal treatment painful?
With modern anaesthesia, root canal treatment should not be painful during the procedure. Most patients report that it is comparable to having a filling placed. Some mild discomfort afterward is normal and manageable.
How long does a root canal take?
Most root canals are completed in one to two appointments, each lasting 60-90 minutes depending on the tooth's complexity.
How long does a root canal treated tooth last?
A properly treated and restored tooth can last many years. Regular check-ups and good oral hygiene are essential for long-term success.
Can all teeth be treated with root canal therapy?
Most teeth can be treated, but in some cases — such as severe fractures or extensive bone loss — extraction may be the more appropriate option. Dr. Cho will assess your specific situation.
