Just to add another experience here... I am 35. My parents did not take us to the dentist much as a child. Specifically, I only remember going twice, plus the follow up to fill cavities. As an adult with my own insurance, I started going regularly around the age of 19. My dentist told me at that point, the jaw (or nerve roots? I can't remember specifically) is completely formed and there was no benefit to me having them out at that point vs any other time in my adult life if they weren't bothering me, plus it was a cost that I couldn't afford. I had no issues and wasn't concerned.
Fast forward to 30ish and my bottom wisdom teeth randomly were partially erupted (they were sideways), leaving a pocket that I had a very hard time keeping clean. So I opted to have the bottoms removed but keep the top. It was a tough recovery. Very painful and about 3 weeks or so before I felt normal again. But I don't regret it.
I just went to a new dentist and hygenist this month who complimented my teeth over and over saying they couldn't believe I'd never had braces, my teeth were very straight. So my bottoms erupting were no problem for my alignment. The dentist also noted my top wisdom teeth were still there, and that they will probably never give me any issues because of how high they are. So I felt like I made a good choice to leave them.
Bottom line, I would maybe get a second opinion, but likely hold off. Especially if $2,000 is a large purchase for you (it definitely is for me!).
