The symptoms experiencing are associated with impacted wisdom tooth
which is inflammed.
I would advice you to visit a dentist
as soon as possible.
Depending on the position and space available for tooth eruption
,it has to be either extracted or flap overlying tooth has to be removed.
Take complete course of medicines prescribed.
Gargle frequently using lukewarm saline or betadine
Avoid anxiety and stress.
Take rest if extraction has undergone.
Hope this helps.
