To achieve this he works with you until you are satisfied because your satisfaction is his motivation.

Using the newest technology, he is able to achieve smiles for his patients that are truly theirs and stay true to their overall symmetry.

Associate Dentist at Sydney CBD Dental

Dr Karen-Grealis, an Associate Dentist at Sydney CBD Dental

Known for her gentle approach and unfailing determination to successfully treat even the most complex of dental issues, Ireland-born Dr Karen Grealis earned her Bachelor of Dental Science (with honours) from Trinity College Dublin in 2012.

She began her career by working on complex dental problems alongside a multi-disciplinary team. She went on to provide pre- and post-surgery treatment to patients at the Head and Neck Cancer Clinic in Dublin, exposing her to extremely challenging dental cases. She also has experience in on-call services for serious paediatric and adult dental trauma, and spent time in Sydney treating complex cases for patients with conditions like dementia and MS.

Although Dr Grealis has a fierce determination to tackle challenging dental issues, her approach to patients is caring and gentle. She prefers to get to know her patients and spend time educating them on their oral health and treatment options, which is perhaps one reason why she was nominated for Ireland’s “Sensodyne Sensitive Dentist of the Year” award in 2015.

Dr Grealis is a part of the Australian Dental Association and Irish Dental Association, and continues to pursue ongoing education to further develop her skills. Outside of dental, she enjoys spending her free time outdoors, playing sports, cooking, reading and exploring Australia.
