Helen Yoo, DMD

Dr. Helen Yoo, dentist at Waterloo West Dentistry

Dr. Helen Yoo believes dentistry works best when patients feel genuinely cared for — not just treated. Born in Seoul, South Korea, and raised in Toronto, Helen went on to complete a Bachelor of Science at the University of Toronto before earning her Doctor of Dental Medicine at the University of Sydney.

Before co-founding Waterloo West Dentistry in 2022 alongside her husband, Dr. Andrew Darroch, Helen practiced throughout the Kitchener-Waterloo region — and it was during those years that she fell in love with the community she now calls home.

Helen has a particular passion for cosmetic and reconstructive dentistry, as well as working with younger patients. Still a kid at heart herself, she takes real pride in making dental visits genuinely enjoyable for children, with the goal of building comfortable, positive associations with the dentist that carry into adulthood.

She is a registered member of the Royal College of Dental Surgeons of Ontario, the Ontario Dental Association, and the Canadian Board of Aesthetic Medicine, and is additionally qualified to provide neuromodulator (muscle-relaxing) treatments for patients dealing with TMJ disorders and jaw pain.

Outside the clinic, Helen can usually be found at a spin class, experimenting in the kitchen, or on a mini adventure with Andrew and their labradoodle.

Trust Us

Caring, Sensitive Staff

At Waterloo West Dentistry, we understand that many people are cautious or hesitant about coming to see the dentist. Whether you are nervous about a dental appointment, are concerned that you will be judged on the condition of your teeth, or have other personal concerns or needs that require more personalized treatment, our team is considerate and kind.

Let us know what concerns you have, and we will find a solution. Our friendly team is not judgmental, and we are here to help. We will make every effort to ensure you are comfortable and relaxed. Sedation dentistry is an option for those who are extremely anxious about a treatment, or to make a lengthy treatment more pleasant. If you are unable to remain still for long periods or require other accommodations, simply let us know. We can break up treatment into shorter periods, or find other ways to get you the care you need.

With Waterloo West Dentistry’s wide range of services, you can get all the oral care and treatment you need, including more complex procedures like extractions, dental implants, and root canals, so you know you can have personalized care for all of your dental care needs.
