Can wisdom teeth open up after extraction months later?

Anonymous
My gums started getting sensitive and Last night I started to see where I got my wisdom teeth pulled right by my teeth is a little opening its a bit swollen. This happened before become swollen then goes away but I see a little opening what's happening? I went to dentist 3 weeks ago and everything is fine but this sensitivity started 4 days ago.
