I've only heard of this recently, could someone tell me;
Why would a tooth supra errupt?
Can a tooth which has had a root canal supra errupt?
How much will it actually 'grow out'/errupt?
Will it go back in again and if so what makes it do that?
Thanks!

Since my problems began after a root canal, I will copy something from my notes which explains why teeth erupt after root canals. It is pretty technical.
Amputation of the nerve inside the tooth, (which is the technical definition of a root canal procedure) frequently causes some inflammation and swelling of the hammock ligament fibers. The Hammock ligament may be further inflamed by overextension of the file beyond the tip of the root during the procedure, as well as by the forcing of debris and fluids beyond the tip of the root into the hammock ligament during the cleaning of the canals. This, in turn can cause a slight elongation of the tooth in its socket which means that unless the top of the tooth is shortened (ie. the occlusion is adjusted) to avoid hitting the opposing teeth, normal biting, and especially grinding and clenching (hyperocclusion) can traumatize the hammock ligament. This causes further swelling and pain in the ligament which increases the elongation of the tooth and further trauma from hyperocclusion which causes further swelling etc. etc. This vicious cycle is very painful. Even very slight pressure on the tooth can can bring tears to the eyes of a Marine! The treatment for this problem is generally to reduce the occlusion on the tooth so that it cannot make contact with the opposing dentition.
Hope that helps. Deb

Thanks Deb. This is interesting and a little alarming! Actually I had a root canal done in Jan and it has been swollen around the gums recently for unknown causes, you made me wonder if this tooth has swollen hammock ligament fibres. It doesn't hurt now to press on it though though it was a little sensitive a few weeks ago.
So does a supra erupted tooth not 'go down' again on its own ever? I don't think I have this, though I can't be sure, but I'm curious, and can't find much doing a google search on supra erruption. In a way I superficially initially liked the idea of it, if for example you damage a tooth regrowth seems a good thing, but I've realized the process doesn't quite work this way!
