If you have documentation (letter from vet, etc), you should be OK with AKC. A friend of mine had a Terv that had lost a tooth in a fence fight. He went on the be one of the top winning Tervs. She kept a copy of the vet's letter in her tack box and would stick it in her pocket on her way to the ring. After a while the judges recognized the dog and quit asking about it.

Good luck.
