Your body is probably still resolving the abscess. The extraction removes the source of infection and allows your body to fight the infection and win. If the tooth had remained, your body probably would never be able to remove the infection entirely.
The antibiotics are definitely helping with the infection. It may be possible that the nausea is a side effect of the antibiotics or pain medications.
I wouldn't touch the extraction site. I would leave it alone and as long as the swelling continues to shrink and your symptoms improve, you should be fine. Are you scheduled for a follow up with your dentist?
help!! i had an abscess on a tooth that had already had root canal treatment went to the dentist he said i had the abscess after taking an x ray and said the tooth needed to be removed. without asking whether there was anyone to go home wiith me or if the rest of my day was free, he, under just normal injected into the mouth painkiller proceeded to pull the tooth i felt most of it and screamed i had previously asked can i have gas and air or something he said id be "fine" . I rinsed my mouth full of blood was taken another look at into my mouth and was by this time really crying he gave me a laflet and sent me home. I cried all the way home from the shock of it and the pain and was still crying about it all day and since then every time i think about it i fill up with tears, surely this was not correct procedure. I was not given antibiotics before or after. by thhe way this was only yesterday and im now feeling pain in the next tooth but im not going back anywhere near that dentist. Thhe sad thing is ive been with that surgery for 14 years, what should i do.
