Dental treatment to avoid septicemia

Hello to everyone. I'm Jessica. I am 24 years old. I am a victim of a medical malevolence in Italy. My dentist extracted a healthy molar by mistake instead of the tooth of judgment. This mistake caused me a serious infection that quickly spread to the bone. I need 1500 euro to regenerate the bone. My family, unfortunately, can not help me because she has the mortgage to pay. If I do not cure this infection properly, I risk septicemia. Hope you can help me. Thanks in advance
