Scientists invent painless dental filling technique using plasma toothbrush

Scientists at the University of Missouri have invented the future of dentistry— it’s a painless dental filling technique that uses a new plasma brush that disinfects and cleans out cavities, killing bacterias and forming a better bond for the fillings, all in just 30 seconds.

Hao Li, associate professor of mechanical and aerospace engineering in the MU College of Engineering, “in addition, a tooth can only support two or three restorations before it must be pulled. Our studies indicate that fillings are 60 percent stronger with the plasma brush, which would increase the filling lifespan. This would be a big benefit to the patient, as well as dentists and insurance companies.”

Qingsong Yu, associate professor of mechanical and aerospace engineering of the University of Missouri, claims that “there have been no side effects reported during the lab trials, and we expect the human trials to help us improve the prototype.” Humans trials are scheduled to begin next year at the University of Tennessee-Memphis. Apparently, they are expecting the FDA to approve this really soon, with the plasma brush arriving to your dentist as early as 2013.
