Review (3/5): Flavor is lost quickly
These do not actually taste like bubblegum. The flavoring is good at first, but after one or two chews quickly goes away. They do work to help set your invisalign in place though. However, I have been getting optimal results without using them, but do recommend using them on the first day or two of putting in new aligners if they don't quite fit all the way into place, then these will help
