Getting Braces Off ... Blue Stuff on Molars Coming off too?!

I have had braces for 2 years and I'm getting them taken off in 3 days. I have also had this blue cement stuff on the chewing surfaces of my top 2 molars to fix my bite. I was told it would wear down, but it's pretty much the same as it was when they put it on 2 years ago. Are they going to remove it when they take off my braces? If so, how? I imagine my bite will feel strange without it.
