I hvae to have hernia surgery on10/31. i think i have an abcesed tooth. i have antibiotics for it. is it ok to take them?

Check with Surgeon: Having an active abscess can sometimes mean your surgery will be cancelled. Call your surgeon's office right away. Also make a dental appointment asap. There is a strong possibility that you can have the abscess treated by your dentist and then still have your hernia surgery.

Root canal: I would have the tooth treated before your surgery. Sounds like it may need a root canal. At least have the procedure started before the surgery you don't want to have the infection compromise you healing from the surgery.

Yes: I hope all went well for you. Generally speaking, i would recommend delaying any elective surgery if there are other problems that you require active therapy. Especially if this involves infection. Most hernia operations are performed with a synthetic mesh inserted. The big concern with mesh placement is the risk of infection.
