Hole in the back of the cheek

[Jeppe]

I kinda have this “Hole” in my mouth and I don’t know what it is. It doesn’t hurt at all. I’ve recently have had a lot of pain just underneath the “hole”, due to a piece of food getting stuck between my wisdom tooth and the gum. I removed it and I doesn’t hurt or bleed anymore. Could those things be related?

It does look like there might be a pocket due to there not being 100% enough space for the wisdom tooth.
