Do you know this? Years ago several times I noticed children and juveniles playing with their removable braces. That is, they moved the braces within their mouthes, while the braces were not just at their destination in the roof of the mouth. I remember this habit to be very common, while orthodontists weren't just as exalted about it (although the braces were within the mouth ).

A picture showing this habit: https://www.bracesforum.net/smf/pictures_bilder_english_or_german/piercings_and_braces-t1208.0.html;msg44659#msg44659. Do you know further pictures?

I remember a young children in a dentist office who played to "loop" a bionator in his mouth. I also had one, and I was never able to do that.
