Can I sleep without my elastics and only my invisalign tray on? Or do I need to wear the elastics all night as well?

if the purpose as prescribed by your orthodontist is to move teeth then you should wear elastics 20-22hrs a day. If the purpose is to just stabilize the teeth position then night time only wear (sleep time) will suffice.

Dear Patty_cakes25,I will do my best to answer your question with the information provided. How and when you wear your elastics is usually dictated by the orthodontist according to your individual treatment needs. I recommend consulting with your treating doctor. I hope that this helps. Best,Dr. Jenn
