Under normal circumstances, a filling can be performed 1 day after the extraction. The main effect of tooth extraction on the filling is that the extraction is prone to blood seepage within the wound, and the seeping blood will affect the bonding of the filling material. In another case, if the extraction is very complicated, it is likely to cause postoperative mouth opening restriction or facial swelling, which will affect the operation of the filling. In this case, you can wait until about a week to 10 days, when the inflammation in the mouth has been completely eliminated, and then perform the filling. So the shortest time is after 24 hours, and the longest time is about 10 days before the filling can be performed. The filling itself does not have much effect on the extraction wound because the clot in the extraction wound has finished forming after 24 hours, and basically it will not come off.
