I am still having pain 9 days after wisdom teeth extraction. is this normal?

Yes: It can take weeks to couple months to heal from wisdom teeth extraction. It is always OK to contact your surgeon if you have concerns.

Post op pain: That's hard to say over the internet. If the pain is decreasing over time, you're probably fine. However, this should be discussed with the dentist who actually removed your teeth. Follow-up aftercare is part of the responsibility of your dentist and yours to ensure that everything is as expected. Call your dentist and discuss this issue.

Very common: However, the healing process is about 3-4 weeks and sometimes pain is part of it. If the pain is gradually getting better is normal. If concerned, see your surgeon for post-op examination.

Yes, but: Yes, but the pain should be diminishing. If it is not improving, see oral surgeon. You may have persistent dry socket that needs packing.

Unusual: The more difficult the surgery, the longer it will take to heal. Post-surgical care is part of what you paid for. Please call your specialist Oral Surgeon to report your symptoms. He/she may want to see you.
