I brought this up in a thread several weeks back and thought it could make a good question/talking point in the COED forums. So a great addition (or modification really) that I have experienced lately is a lady using an Invisalign retainer for oral activities, both top and bottom teeth. Basically this shrink wraps the teeth like a family couch from the 70s/80s. Removing all sharp edges and softens accidental impacts during more enthusiastic activities. Some of you may say that this is compensating for poor technique.
So what are thoughts from providers? Hobbyists weigh in as well.
As a note, these are brand new Invisaligns. So very smooth, doesn't look like a dogs chew toy.
