How we pick: from owner reports to a ranked, sourced list
Every list starts with what owners report after weeks of use, then the maker's care instructions and the FDA device class.
From question to page in six steps
The same for a cleaner, a tablet, a case or a care how-to.
Choose the question
What readers search for and ask about retainer care.
Read the owners
Public reviews after weeks of use. Each quote is filed with its source.
Check the maker's care instructions
Soak times, water temperature, limits and warnings, from the label or page.
Check the FDA device class
How the FDA classes the device type, read in the regulation text.
Rank and write the verdict
Ordered by fit for a use, checked against the sources.
Re-check every quarter
Sooner when a maker changes its directions.
The sources we read for care steps
Each one is named beside the step it supports.
Where a source is silent, we say so. The AAO's guide skips vinegar, so we mark it "Ask first".
Makers' care instructions and FDA classes we check
Looked up before a product can appear in a list.
| Product type | From the maker | FDA device type we compare it with |
|---|---|---|
| Ultrasonic cleaners | Tank, cycle, power, the solution it expects, and warnings such as Zima's and Align's pacemaker warnings | Mechanical denture cleaner, Class I 21 CFR 872.3530 |
| Tablets and crystals | Soak time, water temperature, ingredients such as persulfates, limits for metal parts | OTC denture cleanser, Class I 21 CFR 872.3520 |
| UV cases and sanitizers | Light type, cycle, any germ-kill claim (quoted, maker named) | UV radiation chamber disinfection device, Class II 21 CFR 880.6600 |
| Cases and travel kits | Size, vents, what fits, how to wash it | None checked |
| Chewies and removal tools | Material and directions for use | None checked |

Questions about how we pick
Do you test the products yourselves?
No. We do not run lab tests. Our guides sum up what owners report after weeks of use and check each product against its maker's specs, directions and warnings.
Is a dentist or orthodontist reviewing the guides?
No. No guide is reviewed by a licensed dental professional, so none says "medically reviewed". Care steps come from the AAO, KidsHealth (Nemours) and the makers' directions, and each one names its source.
Can a brand buy a place or a higher rank?
No. Rankings are never sold. See how we make money.
Why don't you show prices?
Prices change often and differ between stores, so a printed price goes stale. The Check price button opens the store's own page with today's price.
How often are the guides updated?
Every guide is re-checked once a quarter, and sooner when a maker changes its directions or owners report a new problem. The Re-checked this quarter badge shows only while that re-check is current.
