Is the area where the wisdom tooth was removed normally hard? I'm 고민.

Does anyone happen to know?

I had my wisdom tooth removed on one side of my lower teeth, and I don't have the other side originally.

The area without wisdom teeth is where the cheek side of the very back molar touches, and the gums also seem normal (?)

The area where the wisdom tooth was removed is not being touched and the gum is blocking it. Also, it seems like there is hard bone as well.

It's like when a wisdom tooth has erupted but is still impacted.

Is that how it usually is?ㅠ

It seems that the extraction was done about a year and a half ago.
