RCT perforation help

I'm new to this group but don't know where to go for some information. I had
a severe toothache about 6 weeks ago. I'm new to this area so I just went to
a local dentist for help. I was x-rayed and told I have a problem and needed
root canal therapy. They gave me an appointment for 3 1/2 weeks later to
have this done. The pain was severe and I couldn't wait that long. I located
another dentist that was referred to me 160 miles from where I live. I got
an emergency appointment and he did an emergency pulpotomy. That was an
instant relief. However, during the second visit he did a thorough exam and
tested for bone density. It was discovered that another dentist did a root
canal and went through the side of my tooth and the screw/post is about 1/8
inch into the bone. This caused a 50% bone loss. The dentist told me an
extraction is eminent and the sooner the better. My question is.......
Should a dentist that perforated a tooth at least tell the patient??? Now,
I'll probably be needing bridgework causing extra expense...... Thanks for
any information.
