I am a Nurse Anesthetist and used to give anesthesia in dental offices. I am amazed at the lack of safety that is allowed in dental offices nowadays. There MUST be a person in 100% attendence during anesthesia to the patient. The staff must be trained in advanced CPR. You cannot assist the dentist and watch the patient at the same time. This would never be accepted at a training institute and should never be accepted in private practice. It is pure greed that the dentists charge for anesthesia and no longer employ someone who is qualified to give the anesthesia and monitor the patient 100% of the time. At any moment, a patient can have an unexpected reaction or a wisdom tooth removal can turn bloody or a tooth pop into a sinus or any unexpected complication. If it was you or your child or family member that was in danger ....you would want 100% safety precautions!!
