I Have A Extremely Bad Pain In My Temple And

I have a extremely bad pain in my temple and ear due to a wisdom tooth stuck under my second molar but barely coming threw the gum anyways I think it's infected and swollen.the pain is insanely unbelievable. I don't have money to go the dentist or doctor. Anyway I can cure the infection myself?would neosporin work?also I heard a mix of salt and Oregon right on my gum might do it.any truth to that
