The best time to set a tooth after extraction is about 3 months after extraction, preferably not more than half a year, but the specific time to set a tooth depends on the degree of recovery at the extraction site, and cannot be generalized. Usually about 3 months after the extraction, the alveolar bone can be basically stabilized, and it is safer to set the tooth at this time. In the case of elderly people, there may be malnutrition, slower bone growth or inflammation before the extraction, the extraction hole is larger, then the time for veneers needs to be delayed. If there are bone spurs or bone tumors on the bone after extraction, it is necessary to remove the bone spurs or bone tumors before setting the teeth, and then set the teeth, and the time for setting the teeth should be delayed accordingly. However, if the tooth is not repaired for a long time after extraction, it will lead to the elongation of the maxillary teeth and tilting of the neighboring teeth, which will affect the overall occlusion of the oral cavity, so it is best not to set the teeth for more than half a year. It is recommended that patients go to the stomatology department of regular hospitals for consultation and examination, and the professional doctors will formulate appropriate dental veneer programs according to the patients’ personal conditions.
