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 Data is aggregated from public sources and each brand's own terms and can be incomplete or out of date.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
Trays changed every 2 weeks; wear hours not published
20 to 22 hrs/day, trays typically changed every 1 to 2 weeks, with in-clinic check-ins about every 6 to 10 weeks
Spec sheet
Start method
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.
In-office 3D intraoral digital scan (or impression) taken by a dentist or orthodontist; the case is submitted through Smartee's digital workflow (SmarteeDoctor) for a 3D treatment simulation, and aligners are 3D-printed and laser-cut in Smartee's facilities
Material
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.
Proprietary multi-layer BPA-free thermoplastic aligner film (Singapore and UK providers describe it as a multi-layer 'A6/Mastertrack' film, trimmed to the gum line); Smartee also produces its own 'Smartee Platinum' dental thermoplastic sheets. Smartee does not publish a single consumer-facing material brand name on its English site.
Retainers
Not included in the patient tray kit; the dentist orders removable retainers from 6MS after treatment and sets their price
Provider-bundled; some practices include post-treatment retainers in the fee (for example a Singapore clinic includes a pair of retainers with Smartee GS). Not published as a fixed manufacturer allowance.
Whitening
Not published
Not published (not a standard brand inclusion; provider-dependent)
Refinements / touch-ups
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.
Provider-managed; some practices include unlimited refinements (for example Smartee GS at a Singapore clinic), and the higher tiers (GE Infiniti, alpha, GS) are unlimited-stage plans. No fixed manufacturer allowance is published.
Guarantee
No patient guarantee in the current terms: a limited warranty to the dentist covers defects in material and workmanship, not the outcome
Not published (no manufacturer money-back or smile guarantee; any guarantee is set by the treating practice)
Clinical oversight
In-office: a trained dentist examines, prescribes, fits and monitors; 6MS specialists prepare the plan, overseen by its orthodontists, and the dentist approves it
Dentist or orthodontist directed, with in-clinic check-ins about every 6 to 10 weeks throughout treatment
Financing
Set by each practice
Through the provider: many practices offer monthly payment plans, including 0% finance options; terms vary by office
HSA / FSA
The brand's cost page says HSA or FSA accounts can help offset the cost; acceptance is the practice's decision
Not applicable (Smartee is not marketed in the US)
Insurance
Some dental plans may cover part of treatment (brand's cost page)
Depends on market and provider; may be partly covered by local dental or orthodontic benefits where available. Not published by the manufacturer.
Availability
United States and United Kingdom through trained dentists (the company says its providers are in over 50 countries, without separating braces from aligners)
57+ countries via Smartee-trained dentists and orthodontists (China, Spain, the UK, and much of Asia including Singapore); NOT available in the United States (no FDA clearance). Four R&D centers and four manufacturing facilities in China and Spain, plus a European clinical centre in Stoke-on-Trent, UK.
