The reasons for bone spurs after tooth extraction are as follows: a. The extracted tooth may be a single tooth with no surrounding teeth, and it is possible that the alveolar bone itself is unevenly distributed. After the extraction, the alveolar bone is absorbed more unevenly and bone spurs will grow. Second, the doctor did not reset the alveolar bone and pinch it after extraction. If if the doctor’s technique is perfect and the operation after extraction is complete, the chance of growing bone spurs will be small. Third, some people are osteophytes and may have bone spurs after tooth extraction. Patients who have bone spurs after tooth extraction do not need to worry too much, they can grind the bone spurs through alveolar bone trimming, which will not affect the restoration of the movable denture.
