I think the point is that it is very painful and the treatment provides relief, so not much of a scam.
Everyone responding is coming from a place where they were impacted by wisdom teeth, are you instead talking about extracting wisdom teeth as a precautionary practice, before they become a problem? Because otherwise it reads that you are trying to tell people that they are mistaken about a problem they have experienced.
Probably an emotional topic too, given how painful wisdom teeth can be.
Maybe you've just had crap dentists. 30 years ago in my late teens I had exactly one wisdom tooth removed and I still have the others today. It was removed because it was coming in perpendicular to the other teeth, starting to push on neighboring teeth, and that was extremely visible on an x-ray. The others were coming in fine and the dentist left them alone.
I had impacted wisdom teeth and bad mouth pain from 14-18. It was so bad I couldn’t chew on the side it hurt on, when both sides started to hurt I went to the dentist. It was so bad I could only chew with my front teeth at times. He realized they were impacted and removed them.
My friend never had an issue and still has his wisdom teeth, his siblings were not so lucky.
