What is a dental bridge?
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.
How is a dental bridge constructed?
As the name of this appliance implies, the bridge is made out of three pieces
that fit into the open space in the mouth, "bridging" the gap. Most
bridges are made of a pontic tooth (or false tooth), 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).
Who is a candidate for bridges?
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 success of the dental bridge.
What are the different types of dental bridges?
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.
Oral health care and bridges:
The following recommendations will help to eliminate, or reduce, any oral health
problems while your teeth bonded by a bridge:
- Brush your teeth carefully after every meal with fluoride toothpaste and a
soft-bristled toothbrush, as food may become lodged causing the gums and
teeth to become infected. This may lead to further complications resulting
in the loss of the bridge.
- Floss daily. Your dentist, or other oral health specialist, may recommend
using a floss threaded for hard-to-reach places between the bridge and its
adjacent teeth.
- Have your teeth cleaned every 6 months by an oral health professional.
- Limit your sugar and starch intake, as debris left behind from these types
of foods may turn into damaging acids, which, in addition to promoting
plaque formation, may also be harmful to teeth and gums.
- Avoid hard and/or sticky snacks. This includes foods such as popcorn, hard
or chew candy, caramel, and/or nuts.
Most bridges last 8 to 10 years with proper oral hygiene.
