The swelling,fever,headache,ear and throat infection
are the symptoms usually associated with impacted wisdom tooth
I would advice you to get a clinical as well as x-ray evaluation done by a dentist
Based on the alignment and space available for tooth eruption
,it has to be either extracted or flap overlying tooth has to be removed.
Take complete course of antibiotics-analgesics prescribed.
Maintain oral hygiene well.
Gargle frequently using lukewarm saline and betadine solution.
Hope this helps.
