Hello,
I have an eye tooth where most of the area above the gum is broken. The
dentist says below the gum line is OK.
I cannot have a crown because he says there is not enough room for a post as
the root is not deep enough..My dentist has recommended that I have an
extraction.
I am not very good with extraction's and I am wondering what problems I
would have if I just let my gum grow over the hole ? Assuming of course that
under the gum is 100% healthy.
Thanks

If the tooth has not had a root canal treatment you almost certainly
have an infected pulp and can develop an acute abscess at any time.
It's a little unusual to have a canine tooth with a root so short that
it can't be saved (perhaps with crown lengthening). Still, your dentist
has seen the tooth and I have not. If you wish to save the tooth you
may wish to get a second opinion. But just to avoid the extraction is
no reason to do nothing.

Usually, the crown lengthening requires removing good bone from both
adjacent teeth. I find that unacceptable in most cases. Metal posts simply
relocate the fracture point to the apical end of the post. Fibre posts at
least allow some retrievability after post fracture as only the post tends
to break. Ferrules force the fracture to the base of the ferrule
preparation.
I don't restore with ferrules anymore. I only use posts for hero-dontitics
where we only expect to get 1-3 years from the restoration. Give me the
ability to get BOTH a 3 mm bump above the gingiva on 1/3 or more of the root
stump and room to prepare a 4 mm circular recess on the low part of the root
stump, and I will usually restore the tooth with bonded porcelain. These
work very well if you equilibrate the final restoration carefully, and
insist on the use of a NTI. They don't rotate, have good resistance form
and end up with enough surface area to get a strong bond.
Most root stumps that are level with the gingiva or below it, get worked up
for an implant or added to an existing RPD. Obviously, other choices arise
from time to time.

Good point. Still, I work with a good periodontist that in selected
cases can get a good cosmetic result without compromising the adjacent
teeth. I've had some of these restorations survive many years. Still,
I'm guessing this tooth is a goner, based on the observations of the
OP's dentist.
