The results of the seven year study show that the need for fillings was reduced by 30 to 50 percent through preventative oral care.
"It's unnecessary for patients to have fillings because they are not required in many cases of dental decay," said the study's lead author, Associate Professor Wendell Evans of the University of Sydney.
"This research signals the need for a major shift in the way tooth decay is managed by dentists. Our study shows that a preventative approach has major benefits compared to current practice," said Evans.
For a long time it was believed that tooth decay was a rapidly progressive phenomenon and the best way to manage it was to identify early decay and remove it immediately in order to prevent a tooth surface from breaking up into cavities.
