It is not recommended to fill back the filling material directly after it is dislodged.
1. The reason why the filling material falls off, mainly due to the filling material is too much force or the hole is too big, etc., and then fill the tooth again to improve the structure of the decayed hole, choose a stronger filling material, such as natural resin material, fill the tooth and also make a crown for protection, to avoid the filling material to fall off again and again. Therefore, once the filling material falls off, it can not be directly filled back.
2. If the filling material falls off and needs to be filled again, you must cooperate with the professional doctor to clean up the filling material that has not completely fallen off, and then carry out decay, cavity preparation, cushioning, filling, etc., to try to restore the external shape and normal function of the tooth.
If the filling material is not refilled in time after it has fallen out, it may lead to aggravation of the tooth damage, and even tooth splitting may occur. After the filling operation, it is recommended to make regular follow-up visits to check whether the filling material is firm, so that problems can be detected and solved in time.
