If you have a missing tooth, there are three basic ways to have that tooth replaced.
For a dental bridge, each tooth adjacent to the space is prepared for a dental crown. The laboratory then fabricates a single piece that includes crowns on the adjacent teeth and a false tooth suspended between them.
If the teeth on either side of the space need crowns anyway, a dental bridge could be the best option for you. If these teeth are healthy and intact, however, the use of a dental implant will help preserve healthy tooth structure and will probably make more sense for you.
