Is this Dry Socket?

[a.c.111]

I had my wisdom teeth removed 9 days ago. I have healed for the most part. I forgot I am not supposed to be using straws and accidentally used one at lunch today. I have noticed a sour taste in my mouth and saw this little hole in the bottom left area. Is this a dry socket?! It doesn’t hurt but I am unsure of what else it could be. I chew on this side and don’t want to get an infection. I know the pictures aren’t the best but it was hard to get a good picture. Please help, thank you!

It looks like healing site to me, everything is within expected normal healing process. You can’t completely close extraction socket within 9 days and tissues are not fully formed yet, but you definitely can use straw now without causing any harm.
