Arlene P. Dagys, D.D.S., D.Orth., F.R.C.D. (C)

Certified Specialist in Orthodontics for Children and Adults

Dr. Dagys is proud to call herself a resident of The Beach. She has maintained a private practice at 340 Kingston Road for over 20 years. She knows that the smiles of happy Beachers come naturally and is committed to enhancing them wherever possible.

In addition to maintaining her private practice in The Beach, Dr. Dagys is a Staff Orthodontist at The Hospital for Sick Children and an Assistant Professor at the University of Toronto, Faculty of Dentistry, where she lectures graduate students.

Dr. Dagys earned her dental degree from the University of Toronto. She then served a combined residency in Pediatric Dentistry and Maxillofacial Prosthodontics at The Hospital for Sick Children from 1974-1975, under the tutelage of Dr. George Zarb. She has been in practice since 1989.

Dr. Dagys has earned international recognition as a researcher, author and lecturer on the subject of Cleft Lip and Palate and Craniofacial Anomalies research. She was a member of the Executive Committee of the Craniofacial Treatment and Research Centre at Sick Children’s Hospital from 1978-1990. She was also acting head of their Division of Orthodontics from 1981-1982 and a dental representative to the Medical Staff Association from 1986-1991.

Dr. Dagys believes firmly that one of the responsibilities of a professional is to give back to the community. She is one of the founding organizers of Ski for Kids, an annual fundraiser in support of Cleft Lip and Palate Research at The Hospital for Sick Children.

Dr. Dagys has participated in dental treatment outreach programs to First Nations communities in Sioux Lookout and Landsdowne House in Northern Ontario. She was also part of a humanitarian outreach team in Riga in 1993 during the period immediately following Latvia's declaration of independence from the Soviet Union.
