Usually, the cost of 3m resin filling is about 200 RMB in the stomatology department of the regular hospital. 3m resin is the better resin component in the filling material, it has the effect of immediate formation and has better wear resistance and hardness, so it is the resin filling material recommended by the doctor. There are also different filling materials according to the part of tooth cavity, and there are relatively better filling materials, such as the American Cole resin, because its molecular particles and abrasion resistance are harder, so the doctor will also recommend the filling with Cole resin, and both 3M resin and Cole resin are instantly formed, and can meet the patient’s requirements in a short time.
