Lost or damaged aligners are one of the most common — and most avoidable — causes of treatment delays. A few simple habits prevent almost all of them.
The single most common cause of an unplanned clinic visit during Invisalign treatment isn't a fit problem — it's a lost or damaged aligner, almost always from being wrapped in a napkin or tissue and accidentally thrown away.
The One Rule That Prevents Most Losses
Never remove your aligners without your case within reach. Whether at a restaurant, at your office desk, or at a family function, the aligner case should come out of your bag before the aligners come out of your mouth.
Storage Do's and Don'ts
If You Do Lose or Damage an Aligner
Contact your clinic immediately rather than waiting until your next scheduled visit. Depending on your treatment stage, your orthodontist may advise moving to the next tray early, wearing your previous tray temporarily, or arranging a replacement — the right option depends on timing.
