The first week of Invisalign I had severe headaches with jaw pain. My Ortho suggested I should alternate them and double the wear time to 4 weeks so an average of only 8-10 hrs per aligner a day(top during day;bottom at night). I am concerned that this is not adequate time for movement and could damage my roots. Would it make better sense to correct the top and then the bottom later? If the next one fits do I assume enough movement has taken place?
