Like oomis1105 said, never be afraid of going for a second or third opinion. A family member had a problem with her gums which did not cause pain but she noticed swelling. She went to a top notch dentist who said the only way to correct the problem is through a surgery in her mouth, and they would need a couple of hours so she would need general anesthesia, and it would have to be done in a hospital. She went for a second opinion to a dentist that was suggested by an Askan, even though the visit was not covered by her insurance. He told her that the problem is not so severe and he could correct it in his office with a regular local anesthesia. When she told him what the other dentist had said, he told her that many doctors are out to make extra money from insurance companies and therefore put patients through procedures that are not necessary.
I am not saying that is the case by you, but never be afraid of a second opinion.
