Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
As per your complain and presentation of symptoms you are suffering from a recurrent episode of
PERICORONITIS which is inflammation of the gum flap around the wisdom tooth and it is caused commonly due to food lodgement in that area causing infection and inflammation..
The other symptoms like fever and difficulty in biting are due to inflammation..
Nothing to worry continue doing gargles with antimicrobial mouthwash..
Consult a dentist and get an x ray done and as you already know that the wisdom tooth is impacted getting it extracted by an oral surgeon will permanently solve the problem..
As of now the dentist or oral surgeon will advise you a course of antibiotics like
amoxicillin and painkillers like
Ibuprofen for relief..
Maintain a good
oral hygiene and avoid food lodgement in that area..
Always gargle with water or 1:1 solution of mouthwash and water after meals to prevent food and bacteria to accumulate and cause infection..
Hope this information helps..
Thanks and regards..
