Root Canal Treatment

dental root canal treatment

Did you know that your teeth have hollow centres? The pulp of your teeth can be found in this area. Pulp consists of nerves and blood vessels. Blood vessels are important for providing oxygen and essential nutrients to your teeth and nerves are needed to make sure that your teeth can sense feeling.

Injuries can damage your teeth. Whether you’ve had a car accident or a hard blow to your head, a cracked tooth can make your pulp more susceptible to damage. Tooth decay can also put the living tissue of your teeth at risk for lasting damage. Harmful bacteria can break through the outer covering of your teeth and this causes an open cavity to form in the tooth.

If you do nothing to stop tooth decay, it could continue toward the root of your tooth where the pulp is located and this process can lead to irreversible inflammation. The tooth can then become infected and usually an abscess forms. Abscesses can cause extreme discomfort and if you don’t get the infection taken care of, it could spread further into the surrounding tissues.

If the pulp of one of your teeth is damaged or if it becomes infected, you will require root canal treatment.

Root canal treatment explained

Root canal treatment is a dental treatment that is used to repair teeth that are severely damaged. During the treatment, the pulp is removed and thereafter, the tooth is disinfected. A filling is placed into the empty cavity and lastly, the area gets sealed.

Is it painful to get root canal treatment?

Root canal treatment has a reputation of being really painful. However, in truth, it does not hurt that much at all. In fact, people who have experienced root canal treatment compare it to having a normal filling placed. Which is not painful at all.

Root canal treatment can be very successful!

At Markham Smile Centre our experienced team would be glad to help you with any concerns you have about your root canal treatment!

See what our patients are saying:


Everyone here is very friendly and provides excellent care. I received a full exam on my first visit, and everyone took time to answer my questions and ensured I felt comfortable the entire time - exactly what you want when visiting the dentist. I highly recommend Markham Smile Centre for anyone looking for great dental care.


There is an ample parking space before you get into the office. The receptionists welcome us friendly with proper COVID-19 procedures in place. The staff worked with patient very patiently and professionally. My teeth cleaning was done by Ying, she explained every detail to me and I did not feel any pain or uncomfortable at all. Thanks to the best team !


It's been a while since I've been to a dentist but I'm trying to get back on track with health in general. Overall it was great going to Markham Smile Centre! The receptionist (I believe she was Kim) was friendly. The hygienist, Ying, was attentive and gentle during the cleaning; x-ray tech (forgot her name, sorry!) was great too. Dr. Sara Riad explained things with good detail. Looking forward to going back!


I was someone who was nervous and anxious about visiting the dentist, but the team at Markham Smile Centre has made me feel SO comfortable. Kim is so patient and helpful and Dr. Hwang and Rory are both so professional and wonderful. They thoroughly explain the procedure to make you comfortable beforehand and are very gentle. I now look forward to visiting the dentist!


I found this place on a whim when I was looking for a new dentist in Markham. My hygienist ying was super nice and her cleaning was very gentle yet thorough. I saw Dr.Jason and he was very nice and informative in regards to what needs to be done and provided me with all the information I needed to make a choice. Would recommend this place to anyone looking for a new dentist, they’re accepting new patients!!


I have been to many dentists in my life, Dr. Jason is easily the best dentist I have ever been too. He does everything he can to make you comfortable no matter the procedure and is a true professional, as does all the staff at Markham Smile Centre. Truly an amazing dentistry


The clinic was clean and the staff was very polite. I particularly liked the fact that everything was explained to me before going in for the procedure so I knew what to expect at each step. The dental hygienist who did the cleaning for me was also very gentle and took my concerns into consideration. I will definitely recommend them.


Upon arriving to the Markham Smile Centre, my son and I were greeted with a warm welcome by the receptionists. The hygienists and Dentist were very gentle and transparent with what they were doing. The hygienist that worked on my 9 year old son was patient and very friendly with him, which helped ease his nerves. Our overall experience was A+.


Since I was little, I have always hated going to the dentist... Its always uncomfortable and unpleasant. These days, visiting the dentist isn’t so bad! Dr Jason, Rory, and the lovely staff at reception make the experience 100x better. I have had absolutely no issues with the gum graft and cleanings that I’ve gotten done here. Everyone is incredibly friendly and helpful, even when I’m calling in or emailing a hundred questions :). I would highly recommend Markham Smile Centre.


Love this place! All the staffs are friendly and Professional and I mean all, cause I've been to most of their office, Markham , Stouffville, North York, and Maple. Dr. Ko is very professional and patient. Whenever I have questions and concerns he would always reply me . I would say this this dental office take care of you all the way. I would highly recommend everyone to come here for any dental works. =)
