Expert dentists in Sydney
Dr Mark Nieh in Sydney

Dr Mark Nieh, BDS (Otago, NZ)

Welcome to Sydney CBD Dentistry, where our practice focuses on you and your smile. We are located at in the heart of the North Sydney CBD at Level 3, Suite 302, 71 Walker Street, North Sydney.

I graduated from the University of Otago, New Zealand, in 2005. After gaining experience and having received mentoring in several different dental practices, I decided to begin a surgery of my own in Hornsby. The practice is doing well, and I found there was demand from patients to open at North Sydney as well, closer to the city.

I am obsessed about dentistry and its never-ending evolution, and endeavour to make your dental experience a pleasant and mutually rewarding experience.

When you sit on my dental chair, you become my number one priority.

Our whole team is dedicated to your comfort and you will receive our uttermost care and the best treatments in a relaxed, modern and friendly atmosphere. I will only recommend dental treatments to you that I would perform on my own family. While dentally obsessed, I still believe that teeth are fixed so that you can use them, ideally not on anything that will break it again (opening a beer bottle for example).

I believe in the philosophy of enjoying everything in life, in moderation. I consume coffee and tea, just like everybody else, and cannot operate without a strong cuppa in the morning. So while I do like you to come in with gorgeous teeth with minimal staining, I understand indulgences in life and will help you to make good of your teeth every time you come in.

Our team believes in communication. I will not only talk you through your treatment to keep you informed, but also to allay any fears you may have. I will also provide you with options after careful consideration of your current and future treatment needs. I also understand that at times people may be restricted by financial concerns. These will all come into our treatment planning and will be openly discussed with you prior to beginning of any treatment.

I strongly believe in continuing education in any profession. My main interest in professional development in the past few years has been with restorative dentistry involving aesthetic restorations, dental materials research, and implant restorations. I maintain an active account with several prominent overseas research institutes to keep me updated of the material research and treatment modalities.

Outside of work, family is very important to me, especially having 2 young children keeps me busy on weekends.
