A fixed dental bridge is a bridge that is immovable; it is held in place using cement or screws, and only a dentist can remove this type of bridge. A cantilever bridge is a structure in which the false tooth is anchored to only one neighboring tooth. Another type of bridge that can be used is a resin-bonded bridge. These are not as strong as fixed and cantilever bridges, but they are both less expensive and not permanent. Unlike the two aforementioned bridges, which entail the filing of the teeth adjacent to the empty space in order to make room for the structure to be installed, resin-bonded bridges are put in place by inserting a false tooth with metal wings into the space. Then, your dentist will use resin to bond the wings to the adjacent teeth.
