Thanks for query,
Wisdom tooth if not much decayed is very strong and one gets difficulty to extract.
So this normal happening,your doctor has no fault.
After extraction she might given strong antibiotic and anti inflammatory medicines due to hard process surrounding structures are likely to be affected.
If if you think medicine not working then you can ask your doctor to change the antibiotics.
Do antiseptic liquid gargles.
Take light and liquid diet
Ok and bye.
