There are three main ways to replace missing teeth, fixed bridgework, removable dentures and implant restoration.
Fixed bridge work is usually used where there are fewer teeth to replace, or when the missing teeth are only on one side of the mouth. Bridges are usually made of a precious metal base, although smaller ones can be all ceramic.
If the bridge will show, porcelain is then bonded to the base.
You should replace missing teeth for a number of reasons. Your appearance is one reason. Another is that the gap left by a missing tooth can mean greater strain is put on the teeth at either side.
A gap can also mean your ‘bite’ is affected, because the teeth next to the space can lean into the gap and alter the way the upper and lower teeth bite together. This can then lead to food getting packed into the gap, which causes both decay and gum disease.
