North Sydney Dentistry is part of the Cosmetique Dental Group. These figures represent our group as a whole.
At North Sydney Dentistry, we plan care around your individual oral health, concerns and preferences. Whether you are attending for a check-up or considering restorative or cosmetic treatment, our team will discuss the available options, expected benefits, risks, limitations and costs. You are welcome to ask questions and take time to decide whether to proceed.
North Sydney Dentistry was founded by Dr Mark Nieh. After growing up in New Zealand, Dr Nieh moved to Australia and developed his clinical interests in cosmetic and restorative dentistry.
The practice is part of the Cosmetique Dental Group. Our dentists work with the laboratory team to plan restorations and select materials for each patient’s needs.
At North Sydney Dentistry, treatment planning begins with an assessment of your teeth, gums and bite and a discussion of the changes you are considering. Where appropriate, your dentist may use a temporary restoration or mock-up to help assess appearance and function and obtain your feedback. This is a planning aid, not a guarantee of the final result. Your dentist and ceramist use the agreed plan to prepare the final restorations. Suitability, treatment steps and outcomes vary between patients.
Alongside our hands-on artistry, we are committed to utilising state-of-the-art technology to elevate both precision and patient comfort. Our practice is equipped with the latest advancements in digital dentistry—including iTero 3D scanners, CBCT 3D imaging for meticulous diagnostics, and CEREC technology for efficient, single-visit restorations. By investing in modern innovation, we ensure your treatments are faster, highly accurate, and tailored to the highest clinical standards.
Every treatment at North Sydney Dentistry is guided by clinical expertise, genuine compassion, and a commitment to creating healthy, lifelong smiles.
