Dr Nour Tarraf

ORTHODONTIST

Dr Nour Tarraf completed his Bachelor of Dentistry at Cairo University with Honours in 2001, followed by a residency in Orthodontics at Cairo University in Egypt, before relocating to Sydney with his wife in 2005. In Sydney, Nour joined the Orthodontic Masters Degree program, graduating with Honours in 2008.

Nour has a particular interest in the use of aesthetic and invisible appliances, and is one of Australia’s leading practitioners of lingual braces (behind the teeth braces) such as WIN lingual braces. He believes that with today’s technology, every patient can be offered an invisible treatment solution.

Proudly one of the pioneers in using Temporary Anchorage Devices (TAD), Nour has been using them now for over 12 years. This technology greatly increases what is achievable through orthodontics for many patients with missing teeth and severe skeletal discrepancies. It has also expanded the treatment options for adult patients with complicated bite problems.

Nour also has an interest in teaching and research, and is involved in both fields at the University of Sydney where he is doing a part time PhD on the applications of TADs in the management of maxillary (upper jaw) deficiency in growing children. He teaches regularly at the Long Orthodontic Course, as part of the University of Sydney and lectures both nationally and internationally.

Nour is an active member of the Australian Dental Association, Australian Society of Orthodontists, European Society of Orthodontics and the Australasian Society of Lingual Orthodontics.

Nour is always at hand to talk orthodontics to our patients and is committed to providing the most outstanding and state-of-the-art orthodontic care. He resides in Sydney’s eastern suburbs with his beautiful wife and two daughters and when he is not creating beautiful smiles, Nour enjoys spending time with his family, participating in triathlons and is a keen cyclist. He also enjoys a round of golf- playing a handicap 5 in wistful years gone by.
