Lower 2 wisdom teeth removed 6 days ago & still swollen, painful and can't chew. normal?

Needs to be seen: It depends upon the difficulty of the surgery and how impacted the wisdom teeth were, as well as if it's getting better, worse or the same. We can't know for sure over the internet not having treated you nor being able to clinically examine you. Call your dentist and ask your questions and whether or not you should be seen for a post-op check.
