A dental bridge is an appliance used
to replace one or more missing teeth. These appliances
are cemented into place and cannot be removed by the
patient. As the name of this appliance implies, the
bridge is made out of three or more pieces that fit into
the open space in the mouth, "bridging" the gap. Most
bridges are made of one or more pontic teeth (or false
teeth), held together by two crowns (a "cap" that covers
the tooth, approximating its normal size and shape).
This setup is then attached (cemented) to the abutment
teeth (the surrounding teeth of each side of the gap).
Nearly everyone who has one or more
missing teeth is a candidate for a dental bridge.
However, the difference between proper and improper oral
hygiene is generally what determines the long-term
success of the dental bridge.
There are several different types of
dental bridges. Your dentist or oral health specialist
will recommend the most appropriate one for your mouth
condition and the location of the missing tooth or
teeth.
-
Traditional Bridge - a pontic tooth (or false
tooth) is held together by two crowns (a "cap" that
covers the tooth, approximating its normal size and
shape). This trio is then attached (cemented) to the
abutment teeth (the surrounding teeth of each side
of the gap).
-
Resin Bonded Bridge (also known as a "Maryland"
Bridge) - this type of bridge involves the pontic
(false) teeth being fused together to metal bands,
bonded to the back of the abutment teeth with a
resin cement. This type of procedure is common when
the teeth missing are in the front of the mouth.
-
Cantilever Bridge - this type of procedure is
most appropriate when there is only one abutment
tooth on either side of the span.
What is a typical bridge procedure?
During the first visit, the abutment
teeth are prepared. Preparation involves re-contouring
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.
How Long Do Dental Bridges Last?
Dental bridges can last 5 to 7 years
and even longer. With good oral hygiene and regular
prophylaxis, it is not unusual for the life span of a
fixed bridge to be over 10 years.
How Do I Care for My Bridges?
It is important to keep your
remaining teeth healthy and strong as the success of the
bridge (depending on the type selected) depends on the
solid foundation offered by the surrounding teeth.
Brushing twice a day and flossing daily helps prevent
tooth decay and gum disease that can lead to tooth loss.
Your dentist or dental hygienist can demonstrate how to
properly brush and floss your teeth. Keeping a regular
cleaning schedule will help diagnose problems at an
early stage when treatment has a better prognosis.
Selecting a balanced diet for proper nutrition is also
important.
What are the Alternatives to a
Bridge?
Alternatives to a bridge can be a
Removable Partial Denture or
Dental Implants.
