A Bridge is used to replace missing teeth. If you have missing teeth we have four options to consider
Leave the gap.
We will often use the Maryland Bridge design as the major advantage is minimal preparation of teeth (a little bit like Cosmetic Veneers). These tend to be more successful on front teeth but the technology is improving so posterior adhesive bridges are better retained.
Where the teeth are already heavily filled, we can use a conventional Bridge. They are really just a series of Crowns beautifully linked to false teeth. *Note Bridges are not removable by the patient unlike a denture.
