RETAINER HELP

I just got done with my Invisalign I’m not completely happy because he’s scratched up my enamel removing the attachments! Anyway, my question is, should your retainer just look exactly like your last trays with the attachment buttons on to? I presumed my teeth would be rescanned and new retainers made to fit my new smile with the attachments removed? I was hoping for something to completely mould my teeth.

My dentist said “your retainer will be the same as your last trays” … Is that correct? I would greatly appreciate some clarification. Thanks in advance.
