New Plasma Brush promises to help dentists clean and disinfect the cavities for fillings without any pain to the patients

Hao Li, associate professor of mechanical and aerospace engineering in the MU College of Engineering, said that the new brush will help reduce the price required for replacement fillings. “200 million tooth restorations cost Americans an estimated $50 billion a year, and it is estimated that replacement fillings comprise 75 percent of a dentist’s work. The plasma brush would help reduce those costs”, Li said.
