Do you think it is safe to eat popcorn now since my hole is getting small? I haven't have pop corn since Oct. when I was about take my 4 wisdom teeth out in Nov. I just don't want to have any problem if I eat pop corn again.

You should be fine! If you have any concerns, just floss and rinse, since the popcorn shell can get under the gums (I don't mean in the hole- but just under your regular gums-it can weasle it's way under sometimes) and cause big probs for your other teeth. Just be carefull with that stuff!
