News that you need to undergo a root canal treatment is not exactly the anticipated outcome of that most recent dental exam. Even so, there are reasons why your dentist believes that endodontic therapy is in your best interests. What does it mean to undergo a root canal treatment and how can you make sure everything is ready before the day of the procedure? Here are some key preparations that you can begin making right now.

Talk With the Dentist About Why You Need a Root Canal

What causes you to need a root canal? In most cases, one of two things is happening. The results of your exam indicate the presence of tooth decay that has penetrated through the enamel and dentin. At this juncture, it’s beginning to affect the tooth pulp. It’s only a matter of time before things get really bad.

Another of the more common root canal causes are pulp that’s already compromised. This means the pulp is already infected. You need to act now in order to prevent further complications from arising.

One of the questions that come to mind is about the body’s ability to deal with infection. Can a root canal heal itself? There usually has to be some sort of support for that to happen. In your case, any window of opportunity to avoid a procedure and attempt to treat the problem with antibiotics or other non-invasive methods is past. The root canal is the most practical solution.

Learn More About the Basic Procedure

The dentist will be happy to go over all of the basic root canal treatment steps with you. That begins with the preliminary set of X-rays that help the dentist to know exactly what needs to be done. The procedure itself will not commence until you receive some type of sedation.

In the best case scenario, there will be no signs that the infection has spread to the gum. Once the dentist removes the infected pulp, antibiotics are administered to eliminate any lingering traces of the bacteria causing the infection. From there, the tooth is filled. Your dentist may recommend a combination of a root canal and crown to add stability to the tooth as well as enhance the appearance.

Ask about Alternative Approaches

What happens if you don’t get a root canal? That is your choice, but going without any type of treatment is something you should not consider. It may be worth asking your dentist if simply extracting the tooth is feasible. Depending on how much damage is already done to the tooth and what the X-rays show, the dentist might be willing to go this route.

What happens if you leave root canal untreated? You can expect the infection to spread and increase the potential to harm the gums. Over time, the oral infection may increase the odds of developing other types of health conditions.

Nothing good will come from choosing to do nothing. Even if you are not crazy about the idea of a root canal, explore other treatment options and settle on one that will protect your health in general.

Go Over Your Medications and Supplements With the Dentist

There is a chance that some of the medications or the nutritional supplements that you currently take could complicate the procedure. That’s why you want to bring them all and go over each one with the dental team. Be especially aware of any substance that thins the blood, lowers your immune system function, or causes drowsiness.

Dentist are usually knowledgeable about what medications do. They are also aware of how certain types of medical problems can affect a dental procedure. Along with going over your medications, make sure the dentist is aware of any ongoing health issue you are currently managing. Those can also be taken into account during the preparation for your root canal.

Why is a root canal dangerous? In most cases, it carries no more risk than any other invasive procedure. It’s the possible complications from medication or existing health issues that can increase your risk. By going over these factors with your dentist, steps can be taken to keep the risk as low as possible.

Have a Word With Your Dental Insurance Provider

You also need to contact your dental insurance provider and find out if there is anything they need you to do prior to the procedure. There may be a deductible you have to meet or possibly a co-pay that you should provide to the dental clinic before the provider begins to cover any of the root canal treatment cost.

This is also an opportunity to determine how much of the expense the provider will ultimately cover. That makes it all the easier for you to make arrangements to pay for the remaining balance.

Schedule Time Off From Work

At the very least, you need to take off the day of and the day after the root canal. This is especially important if your work is physically demanding. For a short time, the dentist will recommend that you limit your activities. That includes anything that involves lifting, bending, carrying heavy objects, and basically anything that could create too much stress on the body.

Do Some Grocery Shopping

The team at the dental clinic will tell you that soft foods are a good idea for a day or so. That means stocking up on foods that require little to no chewing. Fortunately, there are plenty of foods that you can purchase that do not need a lot of preparation. The list provided by the dental team will give you plenty of ideas of how to plan those meals for the days after the root canal.

Make a Trip to the Pharmacy

How painful is root canal treatment? Some people experience very little pain. The dental team can provide you with a prescription for pain and maybe even some oral antibiotics to take for the first few days. If you don’t feel the pain medication is needed, the dentist can also recommend over the counter products that you can use instead. Remember to stick with that list, since some over the counter products could thin the blood or otherwise complicate the healing.

Arrange Transportation To and From the Procedure

You can rest assured that none of the root canal treatment steps will get underway until the staff verifies that someone is there to drive you home. Ask a friend or other loved one to go with you, ensure you get home safely, and maybe even stay with you for a couple of hours. By then, the sedation will be wearing off and you can function well enough to take care of yourself. Keep in mind that driving is still out of the question for the rest of the day.

Plan on Taking It Easy the Rest of the Day

The hours after the root canal is the perfect time to rest. Use the time to nap, listen to music, watch a movie, or read a book once the sedation wears off. See this as a chance to enjoy some of the down time that always seems to elude you.

Remember to gargle and rinse every few hours. You also want to take any medication provided by the dentist as directed. Doing so will help to prevent bacteria from building up and possibly causing a problem around the base of the tooth.

Your activities will be restricted in the next few days, but the day of the procedure is when you need to remain relatively passive. Once you’ve passed the 24-hour period, you can begin the process of incrementally getting back into your regular routine.

Avoid Certain Activities For Two or Three Days

What activities will be restricted in the days ahead? Don’t lift anything heavier than a pitcher of liquid for the first day. Carrying heavier objects is something that will have to wait for a time. Many housecleaning tasks, especially ones that require you to bend over will have to wait for a few days. If you work out regularly, the trips to the gym are off limits for a time. You can walk and ride a bike if you feel the need for some fresh air or want to work your muscles a little.

Remember that restricting your activities is designed to avoid root canal treatment side effects that would slow your recovery. If you are thinking of doing anything in particular that might cause complications, put if off until your dentist agrees that you can resume all of your usual activities.

Remember that the preparations you make in advance will ensure the day of the procedure goes much smoother. There will be less to tempt you to overdo it in the hours after the root canal, and there will be plenty to occupy your time while the recovery progresses. At times, it may seem as if you are being a little too careful, but don’t attempt to do more than the dental team recommends. In the long run, taking it easy and allowing your mouth to heal will be the best thing that you could do.

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 !

BL

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!

TN

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+.

JW

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.

KL

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. =)

I want to preface my review with the context that I am very anxious during dental appointments. That being said, I want to thank the team at Markham Smile Centre for their care.

I have been seeing Susanne (the dental hygienist) for years. She is very gentle and accommodating to my sensitive front teeth, but I always leave with my teeth feeling thoroughly cleaned.

I recently had a fabulous experience with Dr. Rick and Erica (the dental assistant) for wisdom teeth extractions and a filling. You can tell they prioritize providing superior care. Dr. Rick was so gentle and did the extractions with almost no incisions. I had no swelling at all after the procedures. Needless to say, the filling was quick and extremely well done. I really appreciated that he took the time to explain every step and check in with me throughout. And a big thank you to Erica, who did an amazing job as well; I didn’t realize how big of a difference Bucky the stuffed Beaver would make!

And last but never least, thank you Annie and Jess for your kind greetings every visit. Your welcome smiles make a big difference.

Cheers and happy holidays!

Absolutely amazing experience at the markham smile center! Dr. Camilla is genuine and gives her honest opinion on how to reach your dental goals. The entire team is awesome from the moment you step through the doors, would definitely recommend.

Dr. Camila was truly exceptional. I’ve seen several dentists over the years and have always shared my insecurities and dislike of my smile, but she was the first who truly listened and genuinely cared. She took the time to understand my concerns and created a realistic, thoughtful treatment plan that felt achievable and tailored to me.

We’ve only just started this journey, yet the improvement after a single two-hour appointment was incredible. I walked in hating my smile and walked out unable to stop looking at my teeth. It was a complete transformation, not just in my smile, but in my confidence.

I also can’t say enough about the front desk staff and the entire team. Every single person is warm, welcoming and kind, making each visit feel comfortable from the moment you walk in. Together, this team creates an experience that truly stands out. I’m so grateful to have found this practice and highly recommend it to anyone who’s felt nervous, hesitant or insecure about their smile.

The kindest office you’ll ever be at— I get regularly cleanings with Ying and I’ve gotten incredibly professional advice for my teeth and gum health. Dr. Camilla was fast and professional when I needed to fix some gaps in my teeth and the outcome looks amazing. Plus, reception staff like Edelyn (Sorry if I got the spelling wrong!) are truly gems you don’t find at every dental office. Highly recommended!

I went to Dr. Yoo feeling nervous and blue,
A dental examination was way overdue.
Fillings, a root canal, and even a crown,
This was the plan which caused me to frown.

But the moment I walked through that bright office door,
The staff greeted me warmly – I could not ask for more.
Kind voices, big smiles, they calmed all my fears,
Made me feel like a friend who’d been coming for years!

Dr. Yoo is a wizard, a true dental star,
I thought she’d been sent from Venus or Mars.
The needle? Barely felt it, the numbing was quick,
The root canal flew by (now that’s a neat trick!).

No pain, no stress, just laughter and care,
Soft music, warm hands, and jokes in the chair.
The whole team’s a dream – they’re simply the best,
Turned my dental dread into pure happiness!

So if your tooth’s grumpy or starting to ache,
Run, don’t walk – an appointment please make!
Dr. Yoo and her crew will fix you up fine,
Five glowing stars – actually I’ll make that nine! ⭐⭐⭐⭐⭐⭐⭐⭐⭐

Thank you, Dr. Yoo, and your wonderful crew,
My smile’s never been brighter, and it’s all thanks to you! 😁

I’ve been visiting this dental clinic in Markham for the past three years, and I couldn’t be happier with my experience. I had a tooth extraction done by Dr. Jason, and the entire procedure was incredibly smooth and comfortable. The staff is always friendly, helpful, and very understanding, which makes every visit stress-free. The clinic has a warm and welcoming atmosphere that puts you at ease right away. I highly recommend this clinic for any dental care needs — they truly go above and beyond!

I’m in an urgent situation where I need to get my broken tooth repaired tomorrow and then have a crown placed the day after. After searching through numerous dental clinics, I finally decided to give one a try and made a call. To my surprise, the receptionist was extremely helpful and managed to schedule an emergency tooth repair surgery for me the next day. I’m really grateful to Dr. Camila or their excellent skills—my cavity was only about 1mm away from the nerve, but they still managed to fix it perfectly. They even convinced Doctor Rick for the following day to add two extra hours to the surgery, ensuring my root system was properly treated.

Overall, this clinic is incredibly advanced. They offer full dental scans that you can even create a color image of your tooth. There are several receptionists, each handling different tasks, making the clinic feel modern with a well-organized, rigorous, and efficient workflow. It’s definitely worth recommending! I’m giving it a 5-star rating and hope everyone who sees this review will visit this clinic for their dental care and procedures.

5-Star Review for Dentist Camila

I simply have to give Dr. Camila a perfect 5-star rating! I originally had an appointment for deep teeth cleaning on September 19th, but during the check-up, she found 4 to 5 cavities. The problem was—I had to leave town the following Saturday, and my schedule was so packed I could barely squeeze in any extra time. Just when I was panicking, Dr. Camila, who happened to be on duty and heard about my situation, proactively squeezed me in for treatment the next Wednesday. That thoughtfulness alone blew me away!

I’ll admit I hesitated a little at first, feeling nervous about the procedure. But over the two-hour treatment, Dr. Camila handled every dental issue with incredible professionalism. She walked me through the condition of each tooth in detail and gave clear, easy-to-follow tips on post-treatment care. When she finished, my teeth felt clean, smooth, and looked just as natural as before—all my discomfort was completely gone!

Not only is Dr. Camila incredibly kind and approachable, but her skills are truly top-tier. A huge thank you to the dental clinic for having such a responsible, patient-focused dentist. I can’t recommend Dr. Camila enough—she’s simply the best!

I'm thoroughly impressed with Dr. Yoo's exceptional dentistry skills! She performed both my tooth extraction and filling with precision and care, making the entire experience virtually painless. I was amazed by her attention to detail and gentle approach. The procedures were seamless, and I recovered quickly within a few hours without any side effects, getting back to my normal routine and enjoying my favorite foods in no time. I wholeheartedly trust Dr. Yoo and feel fortunate to have her as my dentist – her expertise and compassionate care have earned her a loyal patient in me! I'd also like to extend my gratitude to Dr. Yoo and her entire team for their kindness, helpfulness, and warm hospitality – they made me feel at ease throughout the entire process. Thank you all for providing top-notch care in such a friendly and welcoming environment!

I had an amazing experience at Markham Smile Centre. From the moment I walked in, the front desk staff made me feel so comfortable and welcomed. They were kind, professional, and really helped ease my nerves before my appointment.

Dr. Ko did a fantastic job removing my wisdom teeth under sedation. I was really anxious going in, but he explained everything clearly, kept me calm, and the whole procedure went so smoothly. I couldn’t have asked for a better dental team.

Thank you to everyone at the office for turning something I was nervous about into a positive and stress-free experience. Highly recommend!

I've enjoyed my experience here ever since I had to come for an emergency in early 2025 and the new patient process was simple & easy.
I've needed a couple things done like root canals, fillings, cleanings, etc and everything was excellently done.
Dr. Camila is really patient, caring, and ensures my comfort during all procedures. The team is also very welcoming & making me feel like family. They assist with scheduling and reminders for appointments.
There is Nitrous oxide (laughing gas) that is available to ease large procedures that I recommend if you're covered by insurance.
Overall, couldn't ask for a better team, you won't regret it. 😀

After going to my previous dental office downtown for over 5 years, I was pretty hesitant to make a change. But the commute eventually got to me, so I decided to give my neighborhood spot, Markham Smile Center a shot. Honestly, I’m really glad I did. Dr. Rick is super professional and takes the time to walk through everything, which made the whole experience a lot more relaxed. Susanne, the hygienist, was amazing super gentle and detail-oriented. The front desk team is was friendly and easy to deal with. Overall, i'm every happy with the switch. Highly recommended if you're looking for a solid local dental office

Most importantly, he did a great job and really listened to my concerns and needs as a patient. It’s not easy to find a dentist who is both skilled and caring. Highly recommend!

I had a cavity filled at the Markham Smile Center. Dr. Rick (Feng) and his team were very helpful and professional throughout the process. I was a bit nervous at first, since seeing a new dentist can be uncertain—you don’t know if they’ll be good or not until after the procedure. Luckily, I was in good hands. They did a great job, and Dr. Rick patiently answered all my questions and concerns.

As for billing, the receptionists provided me with an estimated quote based on what they received from my insurance. My final out-of-pocket payment matched that estimate, which gave me peace of mind.
