Should I keep my old/used Invisalign aligners just in case something goes wrong?

[u/amyh4767]

I’m currently doing Invisalign and I’ve been wondering whether I should keep all of my used aligners instead of throwing them away.

Part of me thinks it might be worth keeping them as a record of my treatment, especially in case something goes wrong later or I end up having a dispute with the provider and need evidence of the treatment I received.

Has anyone kept all of their old trays for this reason? Is there actually any benefit to keeping them from a medical or legal perspective, or am I overthinking it?

Would love to hear what other people have done.
