Orthodontist wants me to wear the Invisalign aligner trays for 1 week instead of 2 weeks.

With new companies coming out, with competition, some of the selling points were faster tray advancement.  Invisalign recently changed their methods to allow changing aligners every week instead of every two.  This is in part to teeth moving  better, as well as designing the aligners to move less per aligner.So, YES, your doctor is right.  One aligner per week is the new method.

its good news for you, as per new research by invisalign , tray is enough by 7days so protocol changed from two week to one week. 

Invisalign® has some competition and has been improving its line of products, so yes; the new method from Invisalign® is swapping your Invisalign® clear plastic aligners out every 7 days instead of every 14 days.



Good luck with your procedure and the results! 

Your orthodontist is correct.  Invisalign recently changed recommended tray wear time is SOME cases (not all).  Since you apparently fit the new criteria your treatment should progress even faster.  Good News.
