A device for root canal treatment, comprising a tube with a first taper configuration and a plurality of through holes on the tube wall. A brush is assembled in the tube, comprising bristles and a brush rod, and the bristles are attached to the brush rod at one end. A control member is used to control the shape of the brush, and the bristles attached to the brush rod are unfolded outside the tube wall, so that the brush has a second taper and is in contact with the inner wall of the root canal cavity established by the root canal file. The water generated by ultrasonic oscillation flows in the tube, and flows out from the through holes along the bristles and into the root canal prepared by the root canal file for filling. It has been verified that the device is easy to put into the root canal prepared by the root canal file, the tube wall tissue debris is used for flushing, the residual in the root canal is effectively avoided, the filling of the root canal is facilitated, the postoperative repeated infection is prevented, the recovery of the tooth function is accelerated, and the healthy oral environment is maintained.
