Why did my orthodontist say to change Invisalign trays every seven days when everyone else seems to change them every two weeks?
Doctor Answers 1
Some orthodontists have Invisalign make twice as many trays as are needed in order to have the patient change the trays weekly. In other words, if the original ClinCkeck says it will take 25 sets of aligners (changing them every two weeks), some doctors prefer to have Invisalign make twice as many trays (each aligner has one half of the movement as usual) and change them weekly. The treatment time and end result is the same.Good luck!
