The cost of apicoectomy is around 1000-3000 RMB. If the apical cyst or granuloma invades a large area, bone grafting is needed at the same time of removal and the cost will increase accordingly. The price of artificial bone powder is relatively high and 6000 RMB may only buy a few grams of artificial bone powder. A review is needed about 3 months after apicoectomy to check the recovery of the alveolar bone in the apical area, which will grow all around the root and is a sign of successful apical surgery. If the root becomes loose after the apical surgery, the affected tooth needs to be extracted.
