Your Team - National Dental Care

Dr. Dalia Yousif

Dentist  |  BDSc (Hons) (Qld)

I graduated from the University of Queensland with a Bachelor of Dental Surgery (Honours) in 2013 and have been a full-time employee of National Dental Care since early 2014.

I am a caring and dedicated dentist with competency, skills and experience across all facets of clinical and general dentistry. In order to provide the highest quality of care to my patients, I am efficient in utilising the latest techniques and state-of-the-art equipment which allow me to produce same-day crowns and ceramic restorations, diagnose early stages of decay with our Diagnocam and show you detailed images of dental conditions within your mouth with our intra-oral cameras.

I am competent in performing Invisalign treatment which allows me to offer my patients a virtually invisible and effective approach to straightening their teeth.

I am very passionate about providing excellent patient care and my focus is always on what is best for my patients. I also have a proven ability to calm and reassure even the most anxious of people.

Outside of dentistry, I enjoy building expert Lego sets with my husband, travelling and spending quality time with my family and friends. I am fluent in Arabic and English.

I graduated from the University of Queensland in 2012 with a Bachelor of Oral Health. Since then, I have gained valuable experience working as an oral health therapist in a busy rural dental practice at Ayr, in North Queensland. This enabled me to attend to the needs of a large variety of patients focusing on preventative care and treatment / management of gum disease. I enjoy exercise and going to the gym whilst also becoming more accomplished in playing modern piano and guitar.
