Hello, Wisdom teeth especially when impacted or partially impacted, can become infected. Removal and antibiotic treatment should stop the infection. As long as proper healing occurs, pain should decrease and you no longer should see pus. Take all medication as directed. Keep the area clean, rinse as instructed and see your dentist or surgeon for a follow up visit. If you feel a sharp or rough area, bring it to the attention of your dentist. This can be polished or may be part of your anatomy not noticed before. A broken section of tooth or filling is possible. An increase in pain may be an indication of a dry socket or delayed healing. This can be extremely painful. See your dentist for treatment and medication. Anti inflammatory medication such as Tylenol or Advil can be taken, but you need to contact your dentist. Thank you for your inquiry. I hope that you feel better soon.
