Nasty taste in wisdom tooth socket after extraction. What can I do?

Wisdom tooth ext. This is not unusual after an extraction, especially if there was an infection. The bad taste is due to the bleeding and drainage of any residual infection. Make sure you follow the post-op instructions given to you by your surgeon, and keep the area clean. If the bad taste continues after 2-3 days, call your surgeon to have the area examined.
Food impaction. Food can easily become lodged in the area where the wisdom tooth was removed. If this is associated with increased ache pain, it may be a dry socket infection developing. See your dentist if these symptoms don't get better.
