Why Shouldn't Invisalign Sets Be Replaced Quicker?

If you speed up your case (change your trays more frequently) you will run the risk of your roots resorbing -- possibly leading to loss of teeth in most severe cases. The timing of the trays is to move your teeth without damage; too fast and your roots may become damaged. Be careful!

If you speed up your own treatment, then you could permanently damage your roots. You're not a dentist or orthodontist so please don't act like one. Do what the doctor prescribes and you'll do fine. Two weeks is the shortest amount of time that you should wear the aligners...period!

There is a certain amount of movement prescribed per tray based upon biological tooth movement. Generally, the aligners require 2 weeks for this movement. There is some individual variation, but this is generally by only a few days.
While you may feel that aligners are moving the teeth properly through to the next tray, problems may be imperceptible until several aligners into treatment. This is because the movement for each tray is only a fraction of a mm.
If you have any additional concerns, please speak to your Invisalign orthodontist or dentist.
