Teeth whitening
Peroxide gels or LED kits lighten tooth color. Many aligner brands bundle whitening because the clear trays can double as whitening trays.
Also known as whitening kit, whitening gel.

At a glance
Updated monthly · checked 11 d agoTeeth whitening: used or recommended alongside at-home aligners, not the aligner treatment itself. Its research-volume score is ~71/100, from 2,359 indexed papers. Our verdict: A real perk when it is included for free, but a cosmetic bonus, not part of the treatment. Do not pay a large premium for it.
Bundled as a "brighter, straighter smile" add-on with treatment.

What the evidence says
Our summary of the research, then the counts it rests on. Each count opens the search that returns it.
Peroxide whitening has solid evidence for lightening surface stains. It changes color, not alignment, and is a cosmetic extra that does not affect the straightening itself.
The score is the one figure here we compute ourselves: a logarithmic blend of the three counts above (every indexed paper, the randomized trials, and the systematic reviews), with a trial or a review counting for more than an ordinary paper. It measures how much research exists on the topic, not whether a product works for you. The same method grades every topic on the accessories index.

What to watch for
Can cause temporary sensitivity and gum irritation, and overuse can harm enamel. Whiten only when teeth and gums are healthy, and follow your provider's timing if teeth are actively moving.

Whitening on Amazon
Made for aligners and retainers and sold on Amazon. What each one is, and anything worth knowing first, is our own summary.
- EverSmile AlignerFresh Original Clean foam (2 pack)View on Amazon
Made by EverSmile
A cleaning foam you put inside the trays and wear. It contains hydrogen peroxide, so it whitens teeth as well as cleaning the trays.
Worth knowing: It whitens, so as with any whitening, ask your provider before using it while teeth are moving.
- Crest 3D Whitestrips Professional EffectsView on Amazon
Made by Crest
Peroxide whitening strips worn on the teeth for a set time each day, not inside the aligners.
Worth knowing: A strip cannot reach the enamel under attachments (the tooth-coloured bumps some aligners use), so ask your provider when to whiten.
