Lost Your Tray? Don’t Panic—Here’s What to Do

If you’re going through Invisalign, there’s a good chance you’ve heard it 100 times: Wear your aligners 20–22 hours a day.

And so, when one goes missing, panic is fully warranted.

At Smiley Dental of Waltham, we’ve had plenty of patients under our belt who’ve lost their trays—and we’re here to tell you: it can be fixed.

📞 Dial (781) 666-6000 right away if you’ve lost an Invisalign tray—we’ll get you back on track

Step by Step: What to Do If You’ve Lost a Tray

1. Search for Every Possible Spot

Well, naturally, the starting point must be the obvious: your pockets, napkins, under your bed, your car’s cup holder. Since Invisalign trays are transparent, they just love playing hide-and-seek.

2. Contact Your Dentist (That’s Us!)

We’ll evaluate where you are at with your treatment and guide your next move. Don’t improvise—something that could hinder you.

3. Don’t Omit Wearing Anything

In case you’ve lost tray #8, and tray #7 still has room, wear that temporarily. If you’ve previously worn tray #9 for a couple of days already, we might tell you to go ahead instead.

4. Don’t Guess

Invisalign is designed with timing. Guesswork can lead to shifting, discomfort, or needing re-do trays.

How We Help at Smiley Dental of Waltham

We’ll assess your case and offer solutions like:

  • Ordering a replacement tray
  • Scheduling adjustments to wear
  • Monitoring progress to keep things on track

Bonus: if you are one of those people who tend to misplace things, we can talk about Invisalign case hacks or switching to Invisalign with fewer trays out at once.

Tips on How to Prevent Lost Trays in the Future

  • Always carry your Invisalign case
  • Don’t wrap trays in napkins at restaurants (they get thrown away)
  • Think about labeling your case or keeping a spare
  • Don’t pop trays out in the car, couch cushions, or public restrooms

And if you do lose another one—it’s alright. We’re here to attend.
