For a Gentle Dentle Experience

At Rouse Hill Family Dental Clinic our priority is to provide you with the best level of dental care, delivered in a gentle way. Our practice was established in 1999, by our owner and principal dentist Dr. Ray Singh. We are Rouse Hill’s original dental practice and have a long history of working in partnership with the local community. Our team of dentists, hygienists, nurses and reception staff love working together, and we inspire each other to always do our best. You will notice this level of enthusiasm and see how it benefits you. We are dental nerds and proud of it!


Our Philosophy

Our philosophy is what sets us apart. We really listen to you. We will take the time to ask you what your dental goals and concerns are and we will work with you in formulating a treatment plan that is right for you. Our goal is for you to have a healthy and beautiful mouth, not just in the short term but for life. That’s why preventive dentistry is the cornerstone of what we do, and why our hygiene recall program is so important to our patients. From early childhood, through to teens, adulthood and for seniors our team will treat the whole family for a lifetime.We understand that for some people, dental visits can be stressful. We want to reduce your stress and we achieve this by:

  • Making every effort to ensure your visit is a gentle and pleasant one.
  • Respecting the time you have set aside from your busy schedule and endeavouring to run on time.

At Rouse Hill Family Dental Clinic we love caring for people. We have a very simple rule. Treat our patients the way we would treat our family and friends. It’s a simple but effective rule and it governs everything we do.


We are a practice that has been at the forefront of dental progress for some time. From CAD-CAM ceramic restorations, digital radiography, implants and orthodontics you can rest assured that your treatment will be state of the art.
