Hello, I Think I Have Pericoronitis. For A Week I've

Hello, I think I have Pericoronitis. For a week I've had a swollen gum over my growing wisdom tooth. It is now at the point where the tooth is barely visible because of it. The bacteria spread to my throat and gave me tonsillitis, fever and terrible pain in my neck, jaw and ear. That has eased with ointment and painkillers but I'm still in tremendous pain in my mouth. What home remedies would you recommend? And would you suggest a doctor or a dentist?
