Can I change my Invisalign aligners if they are still tight after two weeks?

When to Switch Aligners
Considering that you are just starting your Invisalign treatment, it is quite normal for your teeth to feel tight especially if those particular teeth are crowded. If your orthodontist instructed you to change the aligners every 14 days, then follow the recommendation. If however when you switch to aligner #2 there is a fit issue, then contact your orthodontist as soon as possible. Best of luck!
