In alphabetical order. This is not a ranking.
Who is included. A provider can be compared when we have a current review, new patients can start with it in the US, and we could confirm how treatment starts and how progress is checked. A missing price never rules a provider out: practice-set fees are shown as practice fees or as a quote. Being listed is not a recommendation.
Providers that have closed, changed or could not be confirmed are listed under Looking for another provider? on the reviews page. Prices and terms change, so confirm them with the provider before you pay.
Not sure where to start? Our guide to the best clear aligners in the US explains which providers we would look at first, and why.
