I had 10 teeth extracted and an immediate denture placed one week ago. Two days ago, I started having nausea and intermittent dizziness problems and a sinus headache. I went back to the oral surgeon today, he checked my mouth, said everything looks fine so I should feel much better in another week. Do other people have these problems?. I was given antibiotics to take for 4 days following the extraction. I am worried about an infection because I have had joint replacement surgery in the past
