Why isn't using the fingers to push the Invisalign in place good enough?
I recommend using the chewies most at the beginning of each set of new trays, typically for the first few days. As far as I know, there is no magic "chewy formula" that guarantees more successful tooth movement with invisalign. The chewies help seat the aligners and engage the attachments so that the teeth are more engaged and can move more effectively. When using the chewies, one should squeeze into them and hold for a few seconds, and then release. This is more effective than using your fingers.
