Thanks for sharing your concern.
As you have already got a wisdom tooth extracted on one side. you can very well understand that it cannot be treated by medication alone.
It requires surgical intervention due to inadequate space in the jaw.
simultaneous eruption of 3rd molars on either side is always seen.thus it is suggested to get extracted at the same time,if the patients health favors.
Now coming to present pain and infection, you have already taken so many antibiotics i would suggest you to make a visit to dentist
and get it extracted soon.
meanwhile, you can get some normal saline and get the area rinsed with the help of bent needle and normal saline there,if you can do it, its fine or else you can seek someones help in this.
Also do warm saline rinses frequently.
pain killers can be continued every six hourly till you visit your dentist.
Also take serratiopeptidase
along with the medication you are already taking.
maintain very good oral hygiene
for lesser pain and infection.do not let any food debris get accumulated there.
Remove it with brush and then do warm saline rinse for faster relief.
Hope it helps.
