Kathryn Corner,

Dental Hygienist

Kathryn graduated from Niagra College Canada in 2007 with honours and on the President’s Honour Roll. Kathryn’s 15 years of clinical experience was gained working in private practice treating patients of all ages, initially in Canada and then in New Zealand where she treated advanced periodontal disease.

Kathryn loves meeting new people and gets deep satisfaction from educating her patients and finding ways to motivate them to care for their oral health.

“Kathryn is proficient with our Air-Flow machine exclusively used in our hygiene surgery. Air-Flow treatment also known as (Guided Biofilm Therapy) uses a fine spray of warmed water and powder to gently deep clean the tooth surface above and below the gum line. Airflow is suitable for anyone looking for healthier teeth, healthier gums and a brighter smile. From light staining to more severe stains, orthodontic (braces) appliances, implant maintenance and one of the best treatments available today for treating and managing gum disease.

Her love of the ocean means Kathryn is delighted to be in Ballina with all it has to offer. In her spare time Kathryn enjoys being by the ocean and playing in the sand with her kids, sewing, painting and anything crafty. 

Kathryn has a fantastic sense of humour and we are thrilled to have her join our team here at Riverwalk Dental as our dedicated and experienced Dental Hygienist.
