Dr. Ina Ionescu, DMD
Originally from Romania, Dr. Ina discovered her passion for aesthetic and reconstructive dentistry while assisting her husband in his dental laboratory. That early hands-on experience shaped her approach and sharpened the artistic eye she brings to every smile makeover.
Dr. Ina completed her dental education at McGill University’s Faculty of Dentistry in Montreal. Since moving to Toronto, she has practiced as an associate in multiple clinics, offering comprehensive care tailored to each patient’s needs. Her ongoing commitment to learning has led her to complete numerous continuing education courses in prosthodontics, orthodontics, and restorative dentistry.
Fluent in Romanian, English, Spanish, German, and French, Dr. Ina enjoys connecting with people from all backgrounds. Outside of dentistry, she loves traveling (especially to sunny destinations), watching movies and shows, and spending quality time with her family.
Dr. Sina graduated with honors from the University of Toronto, Faculty of Dentistry, after relocating to Canada. At graduation, he received two graduation awards in recognition of his outstanding clinical performance in Prosthodontics and Endodontics.
Prior to immigrating to Canada, Dr. Sina practiced dentistry in Iran for over five years across multiple dental clinics. As a dedicated dentist with a strong commitment to staying current with the latest dental knowledge and techniques, and as a compassionate health care provider, he constantly pursues continuing education courses worldwide to better serve his patients and contribute to the overall oral health of the community.
Dr. Sina’s scope of practice is comprehensive and includes oral surgery procedures such as implant dentistry (both surgical and restorative), bone grafting, wisdom teeth removal, and simple, complex, and surgical extractions. His practice also encompasses periodontal and gum surgeries, including gum grafting and root coverage procedures, root canal treatments, and operative and restorative dentistry such as fillings, crowns, and dental bridges, as well as removable complete and partial dentures.
In addition to his clinical practice, Dr. Sina has extensive experience teaching dentistry to internationally trained dentists seeking board certification in Canada.
Outside of dentistry, he enjoys playing the guitar, working out, attending wellness retreats, practicing meditation, and spending quality time with his family and friends.
