Driven by his passion and desire to aid others with their dental health, he went on to achieve his Fellowship of the Royal Australasian College of Dental Surgeons.

Dr Guirguis' extensive career has also seen him training and working across the UK, New Zealand and country New South Wales, owning his own practice, teaching undergraduate students as a part-time Clinical Instructor at Sydney University, and training at the Las Vegas Institute for Advanced Dental Studies (LVI) for five years.

Although highly experienced and enjoying all aspects of general dentistry, Dr Guirguis particularly enjoys working in the areas of comprehensive full mouth rehabilitation, orthodontics (braces & Invisalign), facial aesthetics (injectables and fillers) and treatment for sleep-disordered breathing, snoring and sleep apnoea.

Dr Guirguis finds his role as a dentist particularly rewarding and enjoys assisting his patients in reaching their outcomes whether through optimal oral health or a cosmetic solution to something they have been challenged with. He additionally finds great joy in interacting with patients and working in a fun environment alongside a wonderful team of dental professionals.

Dedicated to his professional development, Dr Guirguis is continually keeping up to date with the latest orthodontic treatment and postgraduate education in dental sleep medicine. His commitment to the field of dentistry has also previously seen him complete post-graduate studies in orthodontics, implants and cosmetic full mouth rehabilitation - allowing him to achieve recognition as one of only four LVI clinical instructors in Australia.

Outside of dentistry, Dr Guirguis has a passion for travelling with his wife and kids, skiing, golf, tennis, good food and single malt whiskey.

Dr Sam Guirguis is part of the following associations:

  • Australian Dental Association
  • Royal Australian College of Dental Surgeons
  • Australian Sleep Association

Dr Ross graduated from Sydney University in 1979. He practised for a short time in Sydney then moved to London for 8 years. Having returned from London in 1987 he continued in private practice and set up Natural Dentistry in Gordon almost 15 years ago.

Over the last 20 years, Ross has written articles for medical journals and health magazines on the mercury issue in dentistry and on complementary approaches to dental treatment.​

Even on occasion has been a spokesman for complementary dentistry on the radio and in newspapers. His long term interest in Eastern philosophy and medicine has shaped the way he now practices dentistry. From consideration and compassion for patients in the dental surgery to realising that our body’s function, wellness and disease are all interrelated.

​I have spent years developing ways to integrate these Eastern concepts and experience with the best modern dental practice.

The turning point for Ross was in 1988 when a patient asked him to remove her amalgam fillings because she thought they were affecting her health. He was sceptical but replaced her mercury fillings with composite resin. A couple of months after completing the treatment she wrote describing how much her health had improved and how thankful she was for the treatment.

Since then Ross has continued to study areas such as herbal medicine, vitamin and mineral therapies, and acupuncture along with keeping up to date with the advances in dental technologies and treatments. For Ross, there is an excitement and joy in learning and bringing these different areas into my daily practice.
