Should I get crowns on the two upper-front teeth, after root canals?

Crowns over root canals
tooth is quite weak. Due to the
anatomy/shape and function of front
teeth, they are not subjected to the kinds of forces posterior teeth are and
are generally much less subject to vertical fracture. Crowns are most valuable as a way of making
a tooth stronger. In posterior teeth in most instances when a root canal/ endodontics
is done the tooth is greatly weakened.
The back teeth generally have two,
three or more canals and more tooth structure must be removed in order
to do the root canal as opposed to front teeth which almost always have only one canal. If a a front tooth or any tooth is not going
to be crowned it should at least be strengthened with a well done bonded
composite restoration which extends at least into the beginning of the root
canal. No root canal filling material
should be left in the crown of the tooth.
It is also good to know that in a
very weak tooth especially where a lot of the tooth structure is missing the
tooth that has had a root canal should
be further strengthened by a post or posts of titanium or other equally strong
material. When a post or posts are used
they should extend about 2/3ds of the
way down the root of the tooth in the canal or canals and should be fused
through bonding to the tooth.
