Bottom line
Use the retainer your orthodontist recommends immediately after treatment; the highest-risk move is creating a retention gap to save money. Once your teeth are stable and your clinician is comfortable with your plan, replacement economics become worth comparing.

The biggest mistake: delaying retention
If your treatment ends before replacement retainers arrive, teeth can begin moving. Do not create a treatment gap based on an online article. Confirm timing with the clinician managing your orthodontic case.
Long-run ownership cost
Retainers are consumable devices. Losing one, cracking one or wearing through one changes the economics. Our retainer cost calculator models replacement cycles over one to five years.
