Scared to ask my mom for braces?

So, basically I've been wanting them for almost three years now. We've been to the dentist in December and I was supposed to have two teeth removed and get braces in January. I've asked my mom several times in the past months when I'm going to get them but she keeps forgetting about it.
A couple of weeks ago I found a letter from the dentist saying that the insurance company doesn't cover the costs which I believe are like 3000 euros. My mom doesn't know that I read the letter. Now I don't wanna bug her about it cause I don't know if she might be having money problems and I don't wanna act spoiled but I also really wanna fix my teeth and just get it over with.
You think I should ask her what's gonna happen next or just leave it?
Just ask her and see what happens
Just leave it
