Blue marks the lower price only where every compared price is quoted the same way (a monthly price in US dollars); prices quoted in another currency, as a one-time fee or as a provider-set range are shown exactly as stated and never converted. Adverse-event figures are raw counts of reports filed with the FDA, not rates (what the reports mean). Each spec value opens that brand's spec sheet, and its numbered sources verify the specs as a set. None of this is a recommendation: the right choice depends on your case, your budget and, above all, an in-person exam by a dentist or orthodontist.

InvisibleBraces is an informational data platform, not a dentist, an orthodontist, or a seller of aligners. Nothing here is dental or medical advice, a diagnosis, or a recommendation to start, stop, or change any treatment. At-home clear aligners are not right for every case, and moving teeth without an in-person exam carries real risk. Data is aggregated from public sources and each brand's own terms and can be incomplete or out of date. Always consult a licensed dentist or orthodontist and confirm current prices and terms with the provider.

Some outbound links on this site are referral links. If you sign up or buy through one, we may earn a commission at no extra cost to you. It never changes the price you pay or the underlying data. Partner status is one bounded, disclosed signal in how we order results: all else equal it can lift a partner above a comparable option, but it is capped so a clearly cheaper or better-reviewed option still ranks first, and every partner is labeled.

Wear schedule
20 to 22 hrs/day, each set worn about 1 to 2 weeks
Trays changed every 2 weeks; wear hours not published
Spec sheet
Start method
In-office 3D digital scan at an orthodontist; plan built in 3M/Clarity software (Clarity Portal) and aligners ordered by the doctor
Taken by the dentist in the practice: an intraoral scan (3Shape, iTero, Cerec or STL files accepted) or PVS impressions, with x-rays and photos; there is no at-home kit.
Material
Two options: Clarity Aligners Flex (flexible five-layer material, 0.625 mm, covers the gumline) and Clarity Aligners Force (rigid single-layer material, 0.75 mm, more force for bite correction)
Zendura FLX, a dual-shell material (hard outer shell, elastomeric middle layer), 0.76 mm (0.030 in), per 6MS; the FDA summary describes a thermoformed polyurethane-polyester composite.
Retainers
Retainers required post-treatment to hold results
Not included in the patient tray kit; the dentist orders removable retainers from 6MS after treatment and sets their price
Whitening
Not published
Not published
Refinements / touch-ups
Additional/refinement aligners available, ordered by the treating orthodontist
Up to 2 refinements within 2 years are included in the 6MS Invisible Aligners product (aligner page); a no-charge upgrade to a braces solution is offered to the dentist if braces would produce a better outcome.
Guarantee
Not published (depends on the treating practice)
No patient guarantee in the current terms: a limited warranty to the dentist covers defects in material and workmanship, not the outcome
Clinical oversight
Orthodontist-supervised with in-person visits; optional remote monitoring via Grin at some practices (partnership since 2020)
In-office: a trained dentist examines, prescribes, fits and monitors; 6MS specialists prepare the plan, overseen by its orthodontists, and the dentist approves it
Financing
Set by the treating practice; in-office payment plans vary by office
Set by each practice
HSA / FSA
Generally HSA/FSA eligible as orthodontic treatment (subject to administrator approval)
The brand's cost page says HSA or FSA accounts can help offset the cost; acceptance is the practice's decision
Insurance
Partial coverage possible when considered medically necessary; the practice bills insurance
Some dental plans may cover part of treatment (brand's cost page)
Availability
US and international, only through orthodontists and dentists
United States and United Kingdom through trained dentists (the company says its providers are in over 50 countries, without separating braces from aligners)
