I hate it when they try to remove a tooth and it breaks, then they cut the gum to gain access to the root. Then they dig out all the bits that broke off, then you hear a loud crack and are told sorry, we just broke your jaw bone !!

Then they cut out great chunks of gum to expose the crack and hammer in a piece of synthetic bone to help heal the crack. 4 hours later they tell you to come back in 6 months and we can do some more work !!!
Think it can never happen, think again. Now you know why i hate dentists........
