5.0

I had a great experience at Ontario Smiles Dentistry and Orthodontics! I got a full deep cleaning and the whole process was smooth and comfortable. Victoria was amazing and made sure I understood everything and felt comfortable throughout the appointment. She was super helpful, friendly, and professional. You can tell she genuinely cares about her patients. I definitely recommend Ontario Smiles Dentistry and Orthodontics, especially if you’re looking for a great dental team. Big thank you to Victoria for taking such good care of me!

5.0

The dentist was very nice and knew I was scared and I don't do well at the dentist. The dental assistants were amazing and so patient with me when trying to get X-rays. The dental hygienist she was amazing also. She listen to my concerns and was very gentle and let me know exactly what she was going to do next. The front office staff was very helpful and maybe me feel comfortable and welcomed. I'm looking forward to getting my next cleaning.
