Abstract
A dental treating apparatus according to the present invention includes: a hand piece; a head unit; a driving unit; a control unit; a load specifying unit; and a load comparing unit. The hand piece drivably holds a cutting tool on the head unit. The driving unit drives the cutting tool in a normal rotation direction or in a reverse rotation direction. The load comparing unit compares a load detected and a reference load. During a normal rotation period until driving for rotating the cutting tool in the normal rotation direction by the driving unit satisfies a predetermined first condition, the control unit maintains a rotation direction of the cutting tool in the normal rotation direction, and when a result of comparison by the load comparing unit attains a predetermined result during the normal rotation period, the control unit controls the rotation direction to the reverse rotation direction.
