Amazing background music for a cleaning. Super soothing and relaxing experience in something I usually find unpleasant. The staff is also friendly, kind and caring. Especially Stephanie, who is an absolute gem and lovely to talk to. Highly recommend.


I was very satisfied with my experience at Mapleridge Dental. The staff were friendly, thorough in the care they provided, and attentive to all my needs. First-class service!


Recently changed dentistries to be closer to home and found Mapleridge. This has honestly been the best decision I have made for my dental care. The doctors and staff are absolutely amazing: very welcoming, friendly and helpful! They have also made every visit very comforting, which was possibly the biggest concern of mine when looking for a new dental office. Any questions, concerns or fears you may have, Mapleridge will help you every step of the way!


Great experience! Everyone at the clinic was very kind, welcoming, and competent. This was my first visit and I felt very comfortable with all aspects of my appointment; from the booking process, cleaning, and dental exam. I believe communication and honest professional advice are important when choosing a dentist, I feel I got this here... thank you to the entire team.


Mapleridge Dentistry - what a nice surprise! Everyone so friendly, attentive. Modern facility. Dr. Ko took me on an emergency basis and explained my options, after listening patiently to all my concerns.Thank you for making my first experience a welcoming one and I look forward to my next appointment.


Mapleridge has the best team out there- their staff is kind and helpful, and treats you like family. You are actually happy to go to your dentist instead of being scared. Stephanie is such a wonderful dental hygienist and such a lovely person. And Dr. Ko is just incredible- my whole family sees them and we couldn't be happier!


Fantastic experience! I have been to several dentists in the past and I always felt like it was an in and out experience, or they would not explain anything. At Mapleridge they are extremely professional, knowledgeable and explain everything in a lot of detail. I like that I’m able to be aware of what is going on with my teeth. I love the hygienist, dentist and the reception is super friendly. I highly recommend!


My experience at Mapleridge was nothing short of spectacular. They are professional, kind and informative and they explain everything they’re going to do and their reasons for their procedures. I definitely made the right choice in choosing them!


Great staff. The team at the front was courteous, friendly and extremely helpful. I had Dr. Ko as my dentist. Its the 2nd time I've seen him and he was great - he explained everything, walked me through some options, and explained next steps. I'll definitely continue going to Mapleridge dentistry and I'd recommend them to others in Vaughan.


Very clean, friendly clinic. I was very impressed by the dental hygienist Shirine, who took time to explain everything and provide practical suggestions. Dr. Yara was also very professional and gentle. Thorough exam and happy patient! Will be back!
