anxious about the holes

i got my wisdom teeth taken out just about 12 days ago now. ive finally been able to eat much better over the past couple of days, until of course, i noticed ... THE HOLES. i feel like there is food stuck in them. i wouldn't say they are hurting but its slightly uncomfortable. my surgeon did not give me a syringe - but told me to just wash with salt water. im extremely anxious about food being stuck back there and im not sure what to do? will pieces eventually dislodge as the tissue repairs? should i call and have my mouth looked at? at what level of uncomfortableness/pain should i be concerned?
