Does Invisalign really help overbites?

I have had invisalign since May 2016 but I have not seen any results in regards to my overbite. There are less spaces in my teeth. My orthodontist switched me to invisalign g5 because of the overbite (only due to my request). Still no results. Also my jaw clicks a lot when I eat, yawn or open my mouth. It is painful and people hear it when it clicks. Is that normal?
