Generally speaking, it is safer to set teeth about 3 months after extraction. Premature veneering can lead to restoration failure and complications such as alveolar bone resorption and post-veneering pressure pain; too late veneering can lead to tilting of adjacent teeth in the missing tooth area and cause restoration difficulties. After tooth extraction, cavities will be created in the extraction sockets, blood clotting will occur, and blood clots will be mechanized, causing a series of changes such as granulation tissue and fibrous connective tissue generation, alveolar bone resorption, new alveolar bone, and alveolar bone reconstruction. The whole process of alteration occurs slowly and continuously, and the alveolar bone basically stabilizes in about 3 months, so it is safer to place teeth at this time.
