Dr Grant Duncan

(BDS (Adel), MSc (Man, Canada) MRACDS (ortho), FICD)

Dr Grant Duncan

Dr Duncan has been in specialty practice for over 25 years. He received his Bachelor of Dental Surgery from the University of Adelaide. He subsequently went on to achieve his Master of Science in Orthodontics from the University of Manitoba in Winnipeg, Canada. Dr Duncan brought Invisalign to Australia in year 2000, was one of the first Invisalign providers in Australia to be honoured with Black Diamond Provider status in January 2017. This is in recognition of his commitment to and clinical experience with Invisalign treatment. He is part of the national Invisalign accreditation team, lectures nationally and internationally on the Invisalign system, and is a clinical tutor on Invisalign within the graduate orthodontic program in the University of Adelaide. Dr Duncan is a member of the Royal Australian College of Dental Surgeons, and an invited member of both the prestigious Pierre Fauchard Academy of Dentistry, and the International College of Dentists. Dr Duncan has a wide range of clinical experience and interests, and is recognised as a global leader in Invisalign treatment. Dr Duncan holds a strong belief that Invisalign is a better and healthier alternative to braces, and that almost all adults and children can be treated with Invisalign. Early Invisalign treatment of children to allow for bite correction and arch development usually negates the need for braces and extractions at a later age.

Dr Sarah Dan

BDS (Adel),D Clin Dent (Orth) (Syd), MRACDS (Orth) (Syd)

Dr Sarah Dan

The world of orthodontic treatment is not what it was and I love that. Patients not only want more from the experience, they expect great results too. I endevour to provide both through my dedication to individualised diagnosis and treatment planning and by treating every patient as I would like to be treated. 

I completed my Bachelor of Dentistry at the University of Adelaide in 2002 with Dean’s Honours. Following several years in private practice, I completed my Doctor of Clinical Dentistry in Orthodontics at the University of Sydney in 2009.  Receiving prizes for my clinical results and research I also simultaneously qualified as a Member of the Royal Australasian College of Dental Surgeons in the specialist field of Orthodontics.

I value continuing education and have a strong ongoing connection to the University of Sydney. I am also a member of a number of Australian and international professional associations, including the Australian Society of Orthodontists, the American Association of Orthodontics and the World Federation of Orthodontics. This keeps me informed on the latest advances in orthodontics so I can provide the best for my patients.

Between my own study and my direct experience of having braces later in life, I came to appreciate the real value of quality orthodontic treatment. I went through my teens and part of my twenties not liking my smile because I didn’t think braces were cool. But something changed in me when I realised I could feel better. Since having my teeth straightened, I can honestly say my life has improved and I feel more confident. This made me appreciate that orthodontics can transform lives. Knowing that I can help people be the best they can be and feel great about themselves makes me love my job and it is the reason why I became an orthodontist.

It is so satisfying and rewarding to see the confidence and amazing smiles of my patients every day. 

I feel very passionate about this and thus I am publishing a book in 2018 titled “So Smile – a guide to straightening up the confusion around orthodontic treatment”.  With this, I am hoping to educate patients so they can get the best out of their orthodontic treatment. 

Furthermore, since 2009 I have also been a contributor to Give a Smile, a charitable public health initiative of the Australian Society of Orthodontists, where I have provided pro bono care to numerous patients. It is a wonderful feeling being able to give back, educate and empower.

Yes, I’m an orthodontist, but more than that, I see myself as being able to work with my patients to feel better about themselves and life. It doesn’t matter if my patients are kids, teens, or grown-ups. I take time to listen and really show I understand so they feel comfortable and supported throughout their orthodontic treatment. 

Having had orthodontic treatment myself, treating my husband with invisalign and now having two young children who will need orthodontic treatment in the near future, I can easily emphasise with my patients and their orthodontic journey.
