Joondalup City Dental has been providing dental services to the Joondalup area since 1993. We have made it our mission to build a long and trusting relationship with every patient who walks through our doors.

We make sure our patients know they are not just numbers, but valued human beings whom we treat as we would members of our own families. It is our goal to provide an extremely high level of customer service. We do this by training our staff to be approachable, professional, caring and friendly. We make it a point not to engage in the “patient-blaming” that is so common in our profession. We are here to heal you: not to judge you.

Some of our longest-standing patients came here first for emergency dentistry and liked us so much they decided to trust us with their long-term care. Others have been with us since they were children and feel so much like a part of our family that they wouldn’t think of going elsewhere.

We offer full service dentistry, as seen by our partial menu below:
