Good news for people suffering from dental cavities. New study has revealed that a no-drill approach can stop tooth decay in majority of cases.
Study conducted by the Australian team found that the need for fillings dropped 30 to 50% provided patients take personalized care after first sign of tooth decay.
Study lead author Wendell Evans, an associate professor at the University of Sydney, said that fillings are not required in many cases of dental decay. Most people believe that even the smallest sign of tooth decay requires a filling, but, Evans said that the tooth decay does not progress and develops at a slow pace.
Evans said it takes four to eight years for decay to grow from the tooth’s outer layer (enamel) to the inner layer (dentine). During this time, the decay can be detected and treated before it becomes a cavity and requires a filling.
Reportedly, the no-drill approach put forth by the Evans consists of four aspects: high-concentration fluoride varnish application to the area of tooth decay, good tooth-brushing skills, and regular monitoring.
Evans said that the early decay can be stopped and reversed and the need for drilling and filling was reduced dramatically. He added, advanced cavities need filling but still a tooth should be drilled where a cavity is present.
Two dentists in the US said that the no-drill approach has some advantage and in few cases it has already shown results.
Dr. Paul Crespi, director of pediatric dental medicine at Cohen Children’s Medical Center in New Hyde Park, N.Y said this a standard practice for children having cavity risk. Patients are treated with dietary modification, fluoride varnishes, and therapeutic dental materials that can reverse dental caries without the need of fillings.
He also mentioned that the U.S. Food and Drug Administration approved sodium diamine fluoride (SDF) a compound that can reverse or stop major cavities without drilling.
