Thanks for posting your query.
Have you got your wisdom tooth erupted or is it still impacted?
The impacted wisdom tooth
can cause ear and throat infection
,difficulty in swallowing ,fever,headache,nausea,metallic taste in mouth.
The pain in palate may also be due to abscess developed from decayed teeth or periodontal infection
I would advice you to get a thorough clinical as well as radiological evaluation by a dentist
Based on the diagnosis,treatment can be planned.
If wisdom tooth is impacted,it has to be extracted or flap overlying tooth has to be removed.
If decayed tooth is present,root canal treatment
and drainage of pus within the abscess have to be done.
Maintain oral hygiene well.
