Honestly, after dealing with dental pain for 20 years and seeing so many dentists around Ontario, I was in a bad way when Jenny from Dr. Day's office spotted me at work. She actually got me an emergency dental service appointment that same day. I've always been scared of dentists because of past experiences, but Dr. Day and his team were so patient and understanding. The receptionist is fantastic too, and Jenny even checks up on me sometimes and offered to help me get home when I was hurting. Everyone there is just incredible - if I could give more than 5 stars, I definitely would!
Owner Response

Can't say enough good things about Dr. Day and everyone at his Ontario practice! They're all so kind and really go above and beyond. What I really appreciate is how they understand my needs and work with my budget - they actually help plan my cosmetic dentistry visits around my healthcare plan. An extra shoutout to Eileen at reception who's always so pleasant and communicates everything clearly. Thanks Dr. Day and team! All the best, Martha
Owner Response

Everyone at the office was super friendly, but here's my issue: they did a procedure I specifically said no to, and I've had constant jaw problems ever since. Since 2020, I've had 7 different doctors in Ontario - ENTs, oral surgeons, orthodontists, even my family doctor - all confirm my jaw is out of place because of this. The dentist still won't admit the mistake, no apology, no fix, and I haven't been able to breathe through my nose properly. Really disappointing experience with what should have been routine dental care.
Owner Response
We take your concerns about your jaw treatment in Ontario seriously at Dr. Colin M. Day's practice. We'd like to discuss this further to understand what happened and explore how we can help. Please contact our office directly so we can address your experience properly.

Been seeing Dr. Day in Ontario for about 10 years now. My previous dentist actually dislocated my jaw, so I was terrified to go back - it took me 2 years to build up the courage even though I needed work. Dr. Day was so patient when I explained what happened, even when I cried and needed breaks during procedures to relax my jaw. Can't say enough about how great he is with patients who have dental anxiety. Really appreciate his care.
Owner Response
We understand dental anxiety can be challenging and appreciate you trusting Dr. Colin M. Day in Ontario despite your previous experience. Thank you for being our patient for 10 years and for acknowledging Dr. Day's patience during procedures. We're here to provide comfortable care whenever you need us.

As a first-time patient in Ontario with a chipped front tooth, I called and they got me in within a couple days, even accommodating a late appointment. The receptionist was friendly when I arrived, and the restorative dentistry work was great - my teeth actually look better than before I chipped them! Really satisfied with how everything turned out and would definitely recommend them if you ever chip a tooth.
Owner Response

Strongly recommend Dr. Colin Day and his amazing team in Ontario! Everything about this dental practice is great: Dr. Day is kind, gentle, and really skilled with general dentistry. Eileen at reception greets you like an old friend, the hygienists teach you new ways to care for your teeth while getting that squeaky-clean feeling, and Judy handles billing accurately. You won't even have time to fully enjoy the comfortable waiting area with the nice artwork and informative video before they call you in. A wonderful practice for family dentistry!

Only went to Colin Day's clinic once a few years ago for an emergency tooth infection in Ontario - my face was really swollen and the infection was obvious. I now know that infections need to be cleared up before any dental surgery or the freezing doesn't work. Colin would have known this as a dentist, but instead of giving antibiotics and rescheduling, he did a root canal on the infected tooth anyway. Not sure why Google is asking for a review now, but that was my experience.
Owner Response
We're sorry to hear about your experience with emergency dental service in Ontario several years ago. At Dr. Colin M. Day's practice, we follow protocols for infections and appreciate you sharing this feedback. We've evolved our procedures since then and would welcome the chance to discuss this further if you'd like to contact our office.

As a healthcare provider myself, I'm really impressed with Dr. Day and his staff in Ontario. I've had bad dentist experiences elsewhere, but Dr. Day was not only skilled but took extra time to educate me about my dental implant issue - something I appreciate since I do the same in my own clinic. No pressure to upsell anything either. If you're looking for an ethical, kind, and highly skilled dentist in the area, he's your guy! Special thanks to Nadia too!
Owner Response
Thank you for your kind words about our dental implant services in Ontario. We're honored that a fellow healthcare provider appreciates Dr. Day's approach to patient education and ethical care. We'll pass along your thanks to Nadia and hope to continue serving you at Dr. Colin M. Day's practice.

Dr. Day and his staff in Ontario are great! Had a filling crumble last night - literally half my tooth was gone. They managed to squeeze me in today without an appointment since it was an emergency, and now my tooth feels totally fixed. Really appreciate how quickly they handled this dental crown situation!

Colin has been my dentist since I moved to Dundas six years ago. It's a difficult process to switch doctors, but Colin and the staff were so professional and kind that the transition was easy. The staff are always receptive to a patient advocating for themselves, which is not always the case in some offices. I kid them by saying that I'm in the 'devil's workshop', but most of the time I'm not thinking it. 💉

They have a great atmosphere here! I went in in immense pain from my wisdom tooth growing in wrong and they saw me the day I called. They were very friendly. I was extremely nervous and in tears from the pain and they helped me remain calm while my mouth was being frozen and while it was removed. I got it removed and haven't had any pain since. I will be recommending to everyone I know in the area. Thank you guys, you're awesome!
