Wear schedule

20 to 22 hrs/day, trays changed roughly every 7 to 14 days per the treatment plan
Spec sheet
Start method
In-office iTero 3D digital scan (or impressions) taken at a dentist or orthodontist, who submits a computer-simulated treatment plan
In-office consultation with a licensed dentist or orthodontist, including x-rays and a 3D intraoral digital scan; the provider designs the plan and fits the aligners
Material
SmartTrack (Align): a highly elastic multilayer thermoplastic developed after testing 260+ polymers, delivering gentler, more constant force
TruGEN and TruGEN XR (Ormco), a 0.75mm polymer free of BPA, latex, phthalates, and mercury; marketed as clearer, more stain-resistant, and better contoured to the tooth than the leading brand
Retainers
Vivera retainers, custom-made and sold in sets of four, commonly $400 to $1,200; nightly wear recommended long-term to prevent relapse
Spark Retainers (launched 2025) available through the provider; retainers required after treatment to prevent relapse (provider-set cost)
Whitening
Not a built-in feature; whitening is done separately by the provider if desired
Not published as a bundled consumer offering; whitening is at the provider's discretion (the TruGEN material is marketed as stain-resistant)
Refinements / touch-ups
Additional aligner sets (refinements) to fine-tune results, typically included within comprehensive plans; exact allowance is provider-dependent
Provider-managed additional trays; TruGEN and TruGEN XR are available for both primary and refinement stages. Refinement policy and cost are set by the treating provider (not published as a fixed manufacturer allowance)
Guarantee
Not published (no manufacturer money-back guarantee; any guarantee is provider-dependent)
No manufacturer-level consumer guarantee; any satisfaction or results guarantee is set by the individual provider
Clinical oversight
Dentist or orthodontist directed, with in-person checkups throughout treatment
Doctor-directed with in-person progress visits about every 4 to 8 weeks (some providers add remote monitoring between visits)
Financing
Through the provider: many practices offer monthly payment plans; terms vary by office
Provider-set in-office payment plans (review examples cite roughly $125 to $167/month depending on term); no brand-run financing program
HSA / FSA
Eligible for HSA and FSA reimbursement as orthodontic care
Generally HSA/FSA eligible as orthodontic treatment (confirmed accepted per NewMouth review); depends on the provider and plan
Insurance
Often partially covered by dental or orthodontic benefits, with many plans applying a lifetime orthodontic maximum (commonly up to about $3,000)
Often covered under orthodontic benefits, though some dental plans treat adult aligners as cosmetic; coverage varies by plan and provider
Availability
US and 100+ countries, delivered through trained dentists and orthodontists: Invisalign's own region picker lists 122 countries and territories, from Canada and Brazil to the UK, Australia, Japan and India (checked 2026-10-10)

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.
