A bridge is used to replace missing teeth. Processed in a lab like a crown, a bridge attaches artificial teeth (a pontic) to adjacent natural teeth (an abutment) by bonding the bridge in place.
Normally a bridge will take two appointments—the first to prep the abutment teeth on either side of the gap left by the missing tooth. This is done by removing a portion of the enamel and dentin and taking an impression that is sent to the lab. They will then construct the bridge that will hold the artificial tooth in place. A temporary bridge is placed to hold the space until the permanent bridge is made and ready to be placed in the mouth. The second appointment is to permanently bond the bridge into place. Another bridge option called a Maryland Bridge uses two wings to attach the pontic to the abutment teeth by bonding the wings to the back of the abutment teeth. This is a less evasive option to replace a tooth.
