At Hornsby Dental, 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.
Hornsby Dental is where Cosmetique Dental Group began. Dr Mark Nieh graduated from the University of Otago in 2005 and opened his own practice in Hornsby. His interests include restorative and cosmetic dentistry, aesthetic restorations, dental materials and implant restorations.
Hornsby Dental is now part of Cosmetique Dental Group, with practices across New South Wales and the ACT, an in-house ceramic laboratory and digital smile design. Our dentists and oral health therapists provide family, preventive and cosmetic dental care. You can speak with the team about your concerns, the available treatment options and their costs before deciding on your next step.
At Hornsby Dental, 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 Hornsby Dental is guided by clinical expertise, genuine compassion, and a commitment to creating healthy, lifelong smiles.
