A dental bridge is a false tooth/teeth (called a pontic/s) that is/are held in place by another tooth or teeth (abutment/s).  

The two most common types are:
Resin bonded (Maryland) - the Pontic has a “wing” attached to it which is “glued” to the abutment

Traditional - this involves crowning the abutment tooth/teeth.

The bridge suitable for you, if any, is dependent on the clinical situation. Ask Sarah when you attend for your check up.
