Muskwa had to have one of his upper canines pulled. My vet gave me three options--pull, cap, root canal. He said odds were the first time Muskwa tried to chew a bone, a cap would snap off. He gave us lousy odds on a root canal working--even worse than the 50-50 your vet gave you. We pulled it. Muskwa was back to normal in three days--eating kibble, bones ect. He's never noticed that tooth is missing.
