I think it would be worth it, and would do it if I were in your shoes.
I had braces as a teenager, but now have a few small things that I kinda wish were fixed, but they aren't big and the dentist has never mentioned. If I was single I would ask the dentist about it, but being married I feel like I'd have to get a sense of if my wife is okay with me looking into it and us potentially spending that much money.
