You should wear your invisible aligners for at least 7 days or 7 nights. When you can no longer feel them pulling on your teeth and they fit perfectly, it's time to move on to the next one.

However, if when you wear a new aligner you find it too uncomfortable, you have two options: either use the orthodontic vibrator to relieve the discomfort, or revert to the previous aligner for a few days to allow the teeth to finish adjusting.

Comfort and pain are very subjective, and their perception varies from one person to another, so you have total freedom to organise your treatment so that it suits you perfectly.
