Signs and symptoms of dry socket may include: 
Severe pain within a few days after a tooth extraction
Partial or total loss of the blood clot at the tooth extraction site, which you may notice as an empty-looking (dry) socket
Visible bone in the socket
Pain that radiates from the socket to your ear, eye, temple or neck on the same side of your face as the extraction
Bad breath or a foul odor coming from your mouth
Unpleasant taste in your mouth
 When to see a doctor A certain degree of pain and discomfort is normal after a tooth extraction. However, you should be able to manage normal pain with the pain reliever prescribed by your dentist or oral surgeon, and the pain should lessen with time. If you develop new or worsening pain in the days after your tooth extraction, contact your dentist or oral surgeon immediately.
