O/T Root Canal Question

[Guest guest]

Snapped off a crowned tooth at the gumline last week and found it had a

tiny sliver of amalgam in it. Evidently the original butcher dentist

drilled a long hole and somehow rounded out the bottom to " anchor " the

amalgam above. We had popped the cap last September and thought we had

gotten it all but discovered this sliver when the tooth broke off.

Anyways, it's out but that tooth also has a receded nerve from a long-

standing abcess below. The dentist recommends a root canal and a post,

then reglue the crown. Any advice?

Thanks, Mark
