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

  • Neither is marked lower, since only monthly prices quoted in US dollars are ranked against each other: AlignerCo $60/mo ($725 one-time) and Smile Aligners £625.

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 Data is aggregated from public sources and each brand's own terms and can be incomplete or out of date.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.
