Patients seeking relief from dental pain at Green Dental in Markham often receive root canal therapy as part of a broader restorative treatment plan focused on preserving natural teeth. This procedure may be followed by crowns or preventive care to maintain long-term function and comfort. With guidance from Dr. Afshin Riazi, treatment plans are carefully coordinated to help Markham patients restore oral health while avoiding unnecessary tooth loss.
Trust Greensborough Dental – Your Root Canal Specialists Markham, for the best root canal therapy
Although our teeth are solid on the outside, they have a hollow canal on the inside that is home to the dental pulp. The pulp consists of nerves, blood vessels and soft tissue. If the pulp gets infected or injured, due to a fracture, dental accident, decay or cavities, Root Canal Therapy, also known as endodontic treatment, might be necessary. Come visit the professionals at Greensborough Dental – your Markham dentist.
Root canal therapy is a dental procedure used to treat infection or inflammation inside a tooth when the inner pulp becomes damaged due to deep decay, trauma, or repeated dental procedures. During treatment, the infected pulp is removed, the inside of the tooth is cleaned and disinfected, and the space is sealed to prevent reinfection. This allows patients to keep their natural tooth instead of removing it. At Green Dental in Markham, Dr. Afshin Riazi performs root canal therapy to eliminate pain while preserving long-term tooth function.
Common signs include:
- Persistent tooth pain or pressure
- Sensitivity to hot or cold that lingers
- Swelling or tenderness in the gums
- Tooth discoloration
- Pain when chewing or biting
Modern root canal therapy is generally no more uncomfortable than getting a dental filling. Local anesthesia keeps the area numb during the procedure, and most patients feel pressure rather than pain. Mild soreness afterward is normal and usually temporary.
Most root canal treatments take about 60–90 minutes, depending on the tooth and number of canals. Front teeth may be completed faster, while molars with multiple roots may require more time or an additional visit.
Real Patient Experience in Markham
Patients requiring root canal treatment at Green Dental in Markham typically visit due to persistent tooth pain or infection affecting daily comfort.

Patients often experience significant relief after treatment and appreciate the ability to maintain their natural tooth through timely care.
The Root Canal Therapy Treatment Process in Markham, ON
Today’s dental technology has made the endodontic treatment process smooth, simple and comfortable.
Oral sedation or local anesthesia is usually used to bring you to a comfortable, relaxed and pain-free state, while our professional dentist at Greensborough Dental gets the chance to do what he excels at the most.
First, Dr. Riazi makes an opening into the chewing surface of the tooth, giving him access to the pulp chamber.
He then removes the infected pulp and cleans the space thoroughly, making sure that there’s no sign of infection left.
The pulp chamber is then filled and sealed carefully, so that there’s minimum to no chance for the infection to reoccur.
In most cases, a dental restoration has to be attached onto the tooth to restore the tooth’s shape, strength and function. The dental restoration also serves as prevention from future damage to the tooth.
Most patients return to normal activities within a few days, and overall recovery typically occurs within less than one week. Mild sensitivity may remain temporarily while surrounding tissues heal.
After the infection is removed:
- A temporary filling is placed
- The tooth is later restored with a permanent filling or crown
- The crown protects the tooth from fracture and restores chewing strength
When properly restored and maintained, a root-canal-treated tooth can last 10–20 years or even a lifetime, especially when protected with a crown and supported by good oral hygiene.
Patients should:
- Avoid chewing on the treated tooth until fully restored
- Eat soft foods initially
- Maintain gentle oral hygiene
- Follow medication and aftercare instructions

Although success rates are high, retreatment may occasionally be needed if:
- Hidden canals were not fully cleaned
- New decay develops
- The tooth cracks or becomes reinfected
In most cases, saving the natural tooth with a root canal is preferred. Preserving natural teeth helps maintain proper bite alignment, jaw health, and chewing efficiency. Tooth extraction may require replacement options such as implants or bridges.
Often yes — especially for back teeth. A crown strengthens the treated tooth and significantly improves long-term survival by protecting it from fracture during chewing.
