Two missing teeth in a row can be treated with removable dentures, fixed bridges and dental implants. Each has its own advantages and disadvantages, and the choice should be made according to the condition of the teeth, the doctor’s recommendation, and economic conditions. 1. The advantage of removable denture is that it is simple, fast and cheap, but it needs to be supported by the neighboring teeth, and the restored chewing function is relatively low. 2. Fixed bridge is a kind of fixed restoration, but it needs the abutment teeth on both sides of the missing teeth to be abraded, and the number of abutment teeth may need to be increased for two consecutive missing teeth. 3. Dental implants are the only restoration method that does not affect neighboring teeth, but the cost is relatively high and the treatment period is relatively long. Therefore, each of the three methods has its own advantages and disadvantages, and the choice should be made according to the condition of the teeth, the doctor’s recommendation, and economic conditions.
