Vibrating dental device could cut brace time in half

Traditionally, dental braces reshape the positioning of one's teeth by applying force to them. The AcceleDent device, worn with braces, simply speeds up tooth movement by vibrating them 20 minutes a day.
In a randomized, controlled clinical trial out of the University of Texas Health Science Center at San Antonio, this vibration accelerated tooth movement by 106 percent during the initial alignment phase, and then 38 to 50 percent later, all without any adverse events
