Was chatting about DIY dentistry with a pal the other night. I'm adapting my own crowns from stock teeth and have bought some dental cement for fixing them (no mre expensive than other glue). A story came out of a bloke that was hospitalised, poisoned by using superglue. If it was the glue or an infection trapped under the tooth or if it really happened I don't know; but I'm really not sure about putting cyano-acrylate in my mouth...
