do dwarf puffers need teeth cutting?

Today a lady approached me and asked me how to cut a dwarf puffers teeth. She said she read about it, i'm just being lazy and not hunting this down, but has anyone heard of this before? It about made my day when I heard it, but still i'm wondering if it is true?

I've heard that if they don't have hard shells to crunch through their teeth will grow too long. Sort of like a beaver, their teeth grow throughout their lives. They need something to wear them down.
