If you lose an Invisalign tray, put your previous tray back in and call your dentist. The old tray holds your teeth in place so they don’t drift while you wait, and your dentist will decide whether to order a replacement or move you on to the next tray. At Lansdowne Family Dental, Dr. Wael Elosta asks patients to call as soon as they notice a tray is missing. This article walks through what to do in the first hour, what to do if you’ve already thrown out your old tray, and how replacements work.
How to Replace Your lost Invisalign Trays?
If you discover that your current Invisalign trays are lost, stolen, broken or damaged beyond use:
- Call our Lansdowne Family Dental office immediately to report the lost aligners and schedule a replacement appointment
- Locate your previous aligner tray set and begin wearing that stage again temporarily
- Come in quickly for replacement records – new molds/scans/photos will be taken by our team
- Create your new customized replacement tray set
- Return to our office once the aligners are ready to continue treatment
The full process typically spans 3 to 5 weeks from realizing aligners are going to receiving new trays. Every patient moves through Invisalign treatment differently, so your specific case, stage, and needs will determine the exact replacement timeline.
Call us as soon as you notice a tray is missing. We can order a replacement quickly, and your teeth keep moving on schedule.

How to Prevent Lost Invisalign Trays?
While one lost tray set during treatment won’t set you too far back, best practices are avoiding mishaps in the first place through careful handling. Follow these aligner care tips:
- Store aligners properly in the case when removed
- Follow reminders about wearing and changing trays
- Choose durable holders like Sync Cases with straps
- Alert us immediately if trays are damaged
- Never wrap aligners in a napkin when dining out
Additionally, make note of the exact stage and order of your aligner trays whenever you switch to new ones. This ensures you can accurately go backstage if ever needed while awaiting replacements.
Being proactive helps prevent lost aligners. But should mishaps happen, act fast by calling our office so we can efficiently order new trays.
What About Replacing Only One Tray?
Sometimes patients lose or damage just one upper or lower tray rather than a full set. Can a single Invisalign aligner be replaced?
The answer is yes – but aligner trays are crafted in synchronized pairs, so a single replacement tray cannot be ordered on its own.
If one is lost beyond use, plan to:
- Notify our office about the singular damaged tray
- Provide the exact number and details of which tray is affected
- Return to our office for updated records
- Wait for both upper and lower aligners in that stage to be recreated
- Resume treatment once the full synchronized set arrives
So while technically only one tray requires replacing, you’ll need to receive a matched set for optimal effectiveness and comfort.
