Tooth-Supported Fixed Bridge. Another front tooth replacement option is a fixed bridge. A bridge consists of a pontic, or the crown in the middle replacing the missing tooth, and two anchors that cover the two adjacent teeth and are cemented into place. Other teeth replacement options may appear to have a lower up front cost, but you will continue to pay that cost over and over, making them expensive compared to dental implants. The cost for a dental implant to replace a single tooth is estimated to be in the range of 3,000 to 4,500, according to The India Times.
