I put of visiting a dentist for quite some time when I first came to Sydney. But after 2 years and a recommendation from a friend, I went to see Dentartisans and have been nothing but impressed with their services.
The equipment in the clinic is state of the art (at least I've never seen a DVD player in a dental clinic before) and the dentists are very passionate about their work.
They also have a lot of information on their website that explains the different types of fillings available and answers frequently asked questions.
