Our Specialists

Our endodontists are dentists who have chosen to limit their practice to the dental specialty of endodontic therapy. In addition to treating routine cases they are experts in performing complicated procedures, including surgery and retreatment of unsuccessful endodontic therapy. An anaesthesiologist is also available to administer intravenous sedation or general anaesthetic if required.
