The old dry socket/wisdom teeth question?

Is a person actually able to see the blood clot in the socket where the wisdom tooth used to be? i'm trying to distinguish if what i see in there is food that i should remove or the blood clot. i tried rinsing and that didn't do anything, but the thing looks so flimsy like food would be and it doesn't look that deep in there. any ideas? the dentist said i could eat stuff other than ice cream etc. around 72 hours after surgery, but now this has shown up. geez, i try to be safe, try not to get the legendary "dry socket" that apparently drops grown men to their knees crying and begging the pain to stop, and this is what happens. lol, so yeah, any ideas?
