After a tooth is filled with bone powder, it usually takes at least three months for it to grow back. It takes about three months for the human alveolar bone to rebuild and stabilize itself, so after a tooth is extracted, it is generally recommended to wait three months before placing a veneer. After implanting bone powder in the alveolar socket, it usually takes about three months to stabilize. If possible, it is best to go to the hospital for follow-up at three months, six months, nine months and one year, so that the doctor can observe the effect and judge the condition of the bone powder. If the bone powder is filled for implantation, it is also necessary to take x-rays on a regular basis so that the doctor can determine the condition of the alveolar bone before implantation. Therefore, it takes at least three months for the bone powder to grow back after filling.
