I have a euro bear skull, and one of the large canines is cracking. The interwebs seems to say that the best thing to do is take some glue that dries white and basically plug the crack. Is this what other folks have done? Or is there a better way? Also, I used polyurethane on the skull itself to help preserve it, but should I do something to the teeth also to prevent any new cracks in the teeth? Thanks in advance.
