Dr. Cyril Tahtadjian

Our practice owner, Dr. Cyril Tahtadjian, founded Dentistry in Streetsville in 1996 with it’s original practice name being the Streetsville Family Dental Centre. His goal was to create a full service dental office to serve the GTA, something that he had dreamed of since deciding to be a dentist at the age of 12. In 1993, he graduated from the University of Toronto Faculty of Dentistry with Honours, having received several awards and scholarships. He completed his residency at the Sioux Lookout Zone Hospital as the Staff Dental Surgeon, where he had the unique opportunity to visit and serve over 25 Indigenous Communities in Northwestern Ontario. Having received his NDEB Certification and RCDSO License, as an ODA and CDA member, he began practicing general and cosmetic dentistry throughout the GTA starting in 1994. In 1996, he was offered a teaching position at the U of T Dental Faculty, which he maintained for 3 years in the Department of Prosthodontics, providing clinical instruction to the senior year students. Dr. Tahtadjian was the first practitioner to introduce Streetsville to Digital Imaging (1993), Dentistry Asleep (1994), Full Phase Implant Dentistry (1996) and Invisalign Orthodontics (2008), all part of the goal in creating a full service clinic with the vision of “Creating a More Beautiful World, One Smile at a Time”.

Dr. Tahtadjian is eternally grateful for the support from the community and patient base that have helped the practice to grow into one of the most recognized businesses in Mississauga, being the only dental office to be awarded the Best Dental Office Award 8 years in a row. In turn, he has committed to returning support as well. He has served on the Executive Board of the Armenian Canadian Medical Association for over 25 years, volunteering and sending aid internationally for medical and humanitarian assistance. Locally, he has supported numerous sports and athletic teams, and has been a sponsor of many Community Events. He has also been involved in Brush-a-mania, Ontario’s largest not-for-profit program designed to promote oral health and awareness among young children from Junior Kindergarten to Grade 6.

“Dr. T” is a proud father of 2 daughters, now both older than he wishes to admit. In his personal time, he enjoys a variety of outdoor sports and activities, including travelling with his family.

He fluently speaks English and Armenian and looks forward to welcoming all new patients to the practice.
