About Us

National Dental Care, Mona Vale (formerly Barrenjoey Dental), is a dental practice of excellence, focusing on quality dental care in a friendly and caring atmosphere. Located in the beautiful Northern Beaches at Mona Vale, Sydney, we aim to provide you with the best possible dental care by combining highly trained dentists, the latest in diagnostic and treatment technology, and the highest quality of materials and workmanship. We aim to do all of this is in a friendly, laid back and relaxing environment. Dr Thomas Giblin, and Dr Laura Siebels all aim to provide you with the best possible specialist and general dental care with a holistic approach and a friendly smile. Our kind and caring nursing staff are always here to help with all aspects in the practice. In order to provide the best treatment to our patients, we have invested heavily in the latest state of the art equipment for both diagnosis and patient treatment. The practice is a true digital practice, with the centrepiece being our high definition Cone Beam CT scanner. This allows us to scan the patient and obtain a three-dimensional image of the patient’s teeth, face, and bones. We have an in-house commercial dental laboratory and dental technicians that fabricate all our crowns and bridges, denture, and other devices onsite. This type of setup is very unique in Australia, with many dentists now sending work overseas to be made. Our lab is heavily invested in technology and uses the latest in CAD-CAM technology and modern dental materials to make all the restorations. Street parking is available, with a local council car park nearby on Bungan Lane.
