If your teeth have not shifted and you simply need a like-for-like replacement, online retainers can be convenient. If the old retainer had already stopped fitting or you notice movement, contact an orthodontist rather than ordering blindly.
- Do not wait weeks to think about replacement after losing a retainer.
- A new retainer should hold the current tooth position, not force significant tooth movement.
- If teeth already shifted, professional assessment matters more than finding the cheapest replacement.
What to do first
Contact your orthodontist if you are early in retention, recently finished treatment, or notice movement. If you have a spare retainer that still fits comfortably, your provider may advise using it while arranging a replacement.
Can you order a replacement retainer online?
Yes, several companies make custom retainers from at-home impressions. This is most suitable when the goal is to reproduce a stable current tooth position rather than correct relapse.
When not to order blindly
If teeth have shifted, the bite feels different, or a previous retainer no longer fits, a new passive retainer may simply lock in the shifted position. In-person evaluation can determine whether active movement is needed first.
