Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that right sided headache, sore jaw and 
sore throat are all evident during inflamed gum flap over the gum flap when there is a partially erupted or erupting wisdom tooth..
Sore throat occurs during 
Pericoronitis due to inflammation in throat that progresses from the wisdom tooth site to the throat due to close proximity of throat and wisdom tooth..
I would therefore suggest you to 
consult a Dentist and get evaluated and a thorough clinical evaluation and investigations like x ray can help in diagnosis and treatment can be done accordingly..
You can be advised a course of antibiotics, anti inflammatory painkiller like 
Ibuprofen, betadine gargles, and warm saline gargles..
In case if it recurs removal of the offending gum flap or 
wisdom tooth extraction can be advised..
Hope this information helps..
Thanks and regards.
