 Painless Dental Filling May Become a Reality Soon
A new painless cavity drill is set to hit dentists' surgeries in the next two years.

The hi-tech "plasma brush" can hollow out rotten teeth in just 30 seconds, with only a slight cooling sensation for the patient.

It uses chemical reactions to disinfect cavities before operations, and forms a bond on the tooth, which is much stronger than current techniques.

This means that fillings will much last longer than before, a huge boost for dentists and patients as currently many stay in place for just a few years.

Scientists from the University of Missouri, who have pioneered the research along with medical technology company Nanova, are confident that the new device marks a huge breakthrough in dental practice.

"Our studies indicate that fillings are 60 percent stronger with the plasma brush," the Daily Mail quoted engineering professor Hao Li as saying.

According to researcher Qingsong Yu, clinical trials are about to begin and are expected to show the uses of the plasma brush.

"There have been no side effects reported during the lab trials, and we expect the human trials to help us improve the prototype," he said.
