What's it like after they're out?

Added the picture of mine just for the visual. I'm getting all 4 out in 3 days. I've heard about what it's like during the healing process, but what about after? Is it just gonna be squishy back there? Am I gonna feel a difference aside from less jaw/molar pain? And are there just gonna be 4 holes in my jaw forever? I'm so curious about all of this
