My wife recently had a root canal and was told by the dentist that the shot in her jaw (hug) was done incorrectly. Wife told surgery needed now to fix

Wife had root canal done and suffered with severe pain over the weekend. Come to find out, the dentist said the shot in her jaw was done incorrectly ( his asst.) and she now has a hemotoma pressing on a nerve and that she requires surgery to correct it. He gave her the names of two (2) specialists to see. The Dentist's office has not called to check on her nor have they offered to have someone attend the appt. with my wife. Should we see one of these specialists or are they simply some of his associates or friends? What should we do. Her mouth has been in pain and numb since the accident which occurred almost 2 weeks ago.
