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.

The bottom line

What actually differs

  • Neither is marked lower, since only monthly prices quoted in US dollars are ranked against each other: 32Co Provider-set and Six Month Smiles Provider-set.
  • Typical treatment differs: 32Co 12-18 months and Six Month Smiles 6-10 months.

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 Data is aggregated from public sources and each brand's own terms and can be incomplete or out of date.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
Not published
Trays changed every 2 weeks; wear hours not published
Spec sheet
Start method
Taken at the dental practice: 32Co syncs with the major intraoral scanner brands, and photos are uploaded by QR code
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
Dentist chooses from 4 double- and triple-layer materials used by traditional manufacturers (for example Zendura FLX), with scalloped or straight trim-lines and rigid or flexible attachment templates
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
Not published
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
Refinements are included in the SOLO lab fee; 32Co reports that 65% of cases finish with no refinement, 31% with one and 4% with two or more
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 for patients (32Co offers dentists a price-match guarantee on lab fees)
No patient guarantee in the current terms: a limited warranty to the dentist covers defects in material and workmanship, not the outcome
Clinical oversight
In-office: the patient's own dentist scans, fits and monitors treatment; every case is planned with a UK specialist orthodontist (Duo) or an orthodontist planner (Solo), and remote monitoring is included as standard
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 practice; 01Health's platform builds patient financing, deposits and billing into the practice workflow
Set by each practice
HSA / FSA
Not applicable (United Kingdom; US HSA/FSA does not apply)
The brand's cost page says HSA or FSA accounts can help offset the cost; acceptance is the practice's decision
Insurance
Not published
Some dental plans may cover part of treatment (brand's cost page)
Availability
United Kingdom (1,200+ partner practices; 01Health says 90% of the UK population lives within 30 minutes of a 32Co dentist); platform licensing offered in the UK and US
United States and United Kingdom through trained dentists (the company says its providers are in over 50 countries, without separating braces from aligners)
