Is it possible to get damages for wrongful child abuse allegation?

Three years ago my son’s teacher reported me to child protective services stating I was physically abusing my son. I had never hurt him and denied it from the beginning. I fully cooperated with the investigation and it was determined that I definitely did not abuse my son. The allegations by the teacher cost me my job and my security clearance. I believe the teacher knew all along that I was not an abuser and made the allegation because of my criticism of her as my son’s teacher which I had reported to the school board. Is it possible to file a lawsuit against her and recover compensation for the damages she caused to me with the wrongful allegation? Could the school system be joined in the lawsuit as her employer if it can be proven that they also knew the allegation was false but continued to employ this teacher?
