The case where there has been a tooth lost then a replacement tooth can be attached to two crowns which are then attached to the adjacent teeth. As the open space is bridged together this is called a Bridge. This is an ideal way to replace a missing tooth and to restore full function and aesthetics. Dental bridge is one method to fill a space created by a missing tooth (or teeth). A dental bridge is made up of 2-3 or more dental crowns for the teeth on either side of the gap and a replacement in between. Dental bridges can also be used to replace multiple missing teeth.
The dental bridge type you choose will depend on the condition of your smile, your cost goals, and the cosmetic results you desire.
Traditional bridges involve creating a crown
for the tooth or implant on either side of the missing tooth, with
a pontic in between. Traditional bridges are the most common type
of bridge and are made of either porcelain fused to metal or
ceramics.
Cantilever bridges are used when there are
adjacent teeth on only one side of the missing tooth or teeth.
Maryland bonded bridges (also called a resin-bonded bridge or a Maryland bridge) are made
of plastic teeth and gums supported by a metal framework. Metal
wings on each side of the bridge are bonded to your existing
teeth.

The Dental Bridge
procedure
During the first visit, the abutment teeth are
prepared. Preparation involves recontouring these teeth by removing
a portion of enamel to allow room for a crown to be placed over
them. Next, impressions of your teeth are made, which serve as a
model from which the bridge, pontic, and crowns will be made by a
dental laboratory. Your dentist will make a temporary bridge for you
to wear to protect the exposed teeth and gums while your bridge is
being made.
During the second visit, your temporary bridge will
be removed and the new permanent bridge will be checked and
adjusted, as necessary, to achieve a proper fit. Multiple visits may
be required to check the fit of the metal framework and bite. This
is dependent on each individual's case. If the dental bridge is a
fixed (permanent) bridge, your dentist may temporarily cement it in
place for a couple of weeks to make sure it is fitting properly.
After a couple weeks, the bridge is permanently cemented into
place.
