Overview

When a patient comes to the dentist for the first time, he asks him some questions about his dental history and his health in general. Then he examines his teeth and surrounding tissues, checks his bite. To reveal any areas of decay dentists take X-rays. Then he must decide what type of restoration is the most suitable for the case. Restorations can be by fillings, inlays, onlays, crowns or by replacement of a gap by fitting a bridge. The dentist uses local anesthesia to reduce discomfort. Sometimes the dentists send their patients to consultants in orthodontics for correction of malocclusion. Dentist’s job requires not only good professional knowledge. A dentist must be able to get on with different kinds of people. The dentist must be quiet, understanding and friendly. And, of course, a good dentist must be able to work as part of a team!
