-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.
however, have any signs of infection, trismus etc., then You SHOULD GO SEE YOUR ORAL SURGEON. That is my disclaimer because I didn't treat the patient. If in doubt, always go see your surgeon. He shouldn't charge you extra for a follow-up and it will bring you peace of mind.

Dry socket (alveolar Osteitis) can have a variety of symptoms. Some people may get it and never know they have it, especially if it comes on late. The most common initial symptoms associated with dry socket are swelling of the area, redness with patches of white around the area, and discomfort. However, these can also be symptoms of the extraction of the tooth, which is why it is good to have a doctor look at it (if you have had a tooth extracted by a doctor, the follow-up visit should not comes with an extra bill).
Hope this helps.
My best to you!
