Auggie, I guess you're talking about fibre posts which bond to the root and appear to work really well. Not like those old "screw in" posts which often , to patients' surprise, fell out (but it was screwed in!) and even split the tooth, although that was hardly surprising with forcing a screw down the canal of an already weakened tooth. *daylia*, There are "posts" which fit into the root canal and generally hold crown and "pins" which fasten into the tooth structure to support a very large filling. These I find very troublesome and try to avoid. Do you Auggie? Also *daylia*, sorry to tell you but nobody's come up with the perfect filling material yet: those that bond are weaker but look infinitely nicer than those that don't. So it's a trade off I suppose. Is it your tooth that's failing around the filling or the filling that's failing in the tooth? Janine
