I would say your dad should first get the 2nd opinion. If the 2nd dentist doesn't agree with the actions of the first dentist and removes the bone, then we know that it was malpractice.
I am moving this thread to All Views so that you can get some serious replies. I am afraid this thread will not get the attention it deserves if it stays here in cafe. Good luck and I hope your dad gets out of this misery asap
