Abstract: Embodiments of the present disclosure provide a sculpting and shaping tool for dental resin, comprising: a handle, a rotating assembly, and a sculpting and shaping tip. One end of the sculpting and shaping tip is coaxially and rotatably connected to one end of the handle through the rotating assembly. When in use, after a resin restorative material is filled in a carious cavity, the sculpting and shaping tip is placed on the resin restorative material. The handle moves to drive the sculpting and shaping tip to rotate, thereby rolling a surface of the resin restorative material. After rolling, the surface of the resin restorative material is smoother and free of protrusions, effectively preventing unevenness on the surface.
