A
crown (sometimes called a cap) is an excellent way to cover and protect
a tooth that has fractured or been damaged by decay. But sometimes,
the damage extends below the level of the bone that surrounds the
tooth. There isn't sufficient tooth structure remaining to support
a crown.
Previously, such extensive damage would mean that the tooth would
be lost. But today, by performing a procedure called crown lengthening,
we can build up the tooth structure so it can support a crown, and
save the tooth. |
Reshaping the bone
|
|
The
procedure
First,
we thoroughly numb the entire area. Then we make small incisions and
gently pull back the gum tissue to expose the surface of the bone.
We reshape some of the bone that surrounds the tooth, then carefully
replace the gum tissue and stitch it in place.
After
a few weeks of healing, we may additionally build up the tooth using
a post or pins and a buildup material. The final step is placing
a crown to cover and protect the damaged tooth. The crown restores
your damaged tooth to normal health, appearance and chewing function.
