Preventative dentistry is the modern way of reducing the amount of dental treatment necessary to maintain a healthy mouth. With the dentist, the hygienist and the patient all working together the aim is to prevent the need for further treatment. This avoids the traditional pattern of fillings and extractions. It is likely that the dentist will work out a course of treatment to get your mouth into excellent condition, and then give you a plan to help you keep it that way.
Your dentist will first assess your teeth and gums, and discuss with you any treatment you need. The main aim is to help you to get your mouth really healthy, so that any dental problems do not come back. In a healthy mouth it is unlikely that decay or gum disease will continue to be a problem.
