Can something be done about a dentist pulling teeth when not necessary?

My daughter walked around Monday complaining about a back tooth hurting I oral gel on it but she said the pain didn't ease. I then thought it may be an ear infection so I took her to my local emergency room where I was told that the ears looked fine. They noticed some swelling on the left jaw and said that it could be from dental issues and was prescribed a pain medicine and an antibiotic. Tuesday morning she woke me up again complaining of pain and this time her jaw was swollen so bad that the eye has been forced shut. I immediately called the dentist and got her in. They dentist told me that they needed to pull 4 teeth on the top in the front to release pressure well of course I gave the OK because I believed the issue to be in the mouth. After the teeth were pulled we were instructed to go to the emergency room where they had been informed that we were coming for a ct scan and antibiotics through IV because the infection was so severe. She went for her ct scan and then the doctor came in with results saying that there was not and infection in the mouth but that she did have an infection because the white blood cell count was high. I then was told she would be admitted to the pediatric floor for observations. After being transported to the main campus and put on the pediatric floor I then learned that the infection was in her skin and soft tissues. This infection was called preseptal cellulitis. I'm am very upset with the dentist pulling 4 teeth at one time on a 6 year old child. And my concern is that if the ct scan didn't show any infection in the mouth then how did the dental x-rays show infection and cause her to lose these teeth. She now has to pretty much relearn how to eat until she gets her permanent teeth in 2-3 years.
