Teeth
need each other for support. When a tooth is lost, the biting forces change
on the teeth next to the space, and they begin to shift. When an opposing
tooth no longer has anything to bite against, it begins to slowly extrude
out of the socket. You may eventually end up losing that tooth, too.
As your bite changes, it becomes increasingly difficult to chew your
food. This change in your bite can also cause damage to your jaw joint
(the TMJ). It's also much harder to clean teeth that have shifted, so
harmful plaque and bacteria accumulate in these new, hard-to-reach places.
This can result in cavities, gum (periodontal) disease, and permanent
bone loss. Bridges correct these problems by filling in the space left
by missing or extracted teeth, stabilizing your bite and remaining teeth.
What is a bridge?
A
bridge is a fixed (cemented in place) dental appliance that is used to
replace one or more missing teeth. Replacing missing teeth with a bridge
restores your normal bite and prevents a number of serious additional
problems from developing. You can chew more easily, and your jaws, gums,
and the rest of your teeth will be healthier. Bridges also improve your
appearance by filling in gaps in your smile.
What material will be used to make my bridge?
Depending
on the situation and the area of your mouth, bridges may be made from:
- porcelain fused to an underlying metal base
- gold
- entirely out of porcelain
- resin (a special plastic hardened in a dental laboratory)
