Welcome to Dentist on Queen

At Dentist on Queen our aim is to provide the highest standard of patient care, treatment and comfort in a caring and modern environment at our surgery based at 97 Queen Street in St Marys. At Dentist on Queen, you can be confident that we will always provide you the best dentistry with the most up to date dental innovative techniques and equipment.


In 1992 Dr Daniel Lu started in St Marys previously in Phillip St taking over from a retiring dentist whom was very hesitant to sell the business to just any dentist.


He was looking to sell his surgery to a dentist 100% focused on patient care as he would be looking after his patients of over 40 years. Dr Lu is still providing  services to the same patients 20 years later in a larger more modern practice and has a team of associate dentists working with him.


Many of our long patients travel long distances for their dental treatment including some patients living overseas.


And at dentist on queen we welcome all new and existing patients and their families to our practice.


Dr Lu and his associates and team at DOQ has been providing quality dental care to patients of western Sydney for over 20 Years servicing many suburbs around Sydney and its surrounding suburbs just to mention a few below;

  • St Marys
  • Colyton
  • Lower Blue Mountains
  • St Clair

Many people are fearful of a visit to the dentist. At Dentist on Queen we are very conscious of this fact and are committed to make your visit to us a pleasant one. This includes carefully explaining treatment, procedures and costs and helping the anxious patient through effective anesthesia where treatment can also be done under laughing gas (Nitrous oxide) and intravenous sedation (sometimes referred to as Sleep Dentistry).This is provided at our surgery with the help of a qualified anesthetist.
