What Could The Blister Behind Wisdom Tooth Be?

I have a blister like structure behind my wisdom tooth, on my gums. It is painful, and is sensitive to touch. The pain and sensitivity extends beyond the structure, and includes sensitivity in the jaw region and also in the throat, near the structure. What is it and what should I do?

Thanks for your query, I have gone through your query.
The blister behind your wisdom tooth can be a pericoronal abscess or it can be a mucocele.
The pericoronal abscess occurs secondary to the gum infection around the wisdom tooth and deposits around the wisdom tooth.
The mucocele can occur secondary to any trauma like biting over the gums from opposing tooth or tooth brush trauma.
Consult a oral physician and get it evaluated.
If I am your treating doctor, If i diagnose it as pericoronal abscess i would have prescribed a course of antibiotics like amoxicillin 500mg and metronidazole 400mg tid for 5 days (if you are not allergic). Then i would have suggested to go for aperculectomy or extraction of wisdom tooth.
If it is a mucocele i would have suggested you to get it treated by surgical excision.
I hope my answer will help you, take care.
