The best clear aligners, compared
There is no single best clear aligner: the right one depends on your case, your budget and how much oversight you want. So instead of a made-up ranking, we compare every brand on the axes that actually differ, and surface the standouts by objective, cited metrics.
Lowest of the 5 brands that quote a monthly price in US dollars. Prices in other currencies or as a one-time fee are never converted to compete.
Shortest midpoint of the stated range among the 70 brands that publish a typical length.
One of the 40 in-office brands, a model that suits complex bites and larger movements that need hands-on care.
Every clear aligner brand, in price order
Ordered by monthly cost in US dollars: the monthly price a brand quotes in US dollars or, for a price quoted in another currency or as a one-time fee, an approximate US-dollar monthly equivalent used only to order this list and never shown as a price. Brands with no comparable figure follow, A to Z. Each price is shown exactly as its source states it and opens that source. How we rank
Monthly prices quoted in US dollars
The 5 brands whose starting price is a monthly figure in US dollars, lowest first: the prices that compare directly exactly as stated. Each opens the source that states it.
Typical treatment length, shortest first
The 70 brands that publish a typical treatment length, ordered by the midpoint of the stated range. Each length opens the source that states it. What sets the length, and what Invisalign says about its own: how long Invisalign takes.
12 brands publish no typical treatment length: uLab (Not published), Orthocaps (Not published), K Clear (Not published), Smiles Club (Not published), i-liner (Not published), OrthoSnap (–), Illusion Aligners (–), Glidewell Clear Aligners (–), Kirei Line (Not published), Orthero (–), LINEO (–) and Graphy (–).

Common questions
What are the best clear aligners?
There is no single best brand: the right choice depends on your case, your budget and how much in-person oversight you want. Remote, at-home brands suit mild crowding or spacing, when you are comfortable with no in-person exam. In-office, doctor-directed systems suit complex bites and larger movements that need hands-on care. We compare all 82 brands on objective, cited criteria so you can pick by what matters to you.
What are the cheapest clear aligners?
Aligner32 quotes the lowest monthly price in US dollars that we track: $33/mo ($695 one-time), the lowest of the 5 brands that quote one. Aligner32 is fully remote (mail-order, reviewed online). Brands priced in another currency or only as a one-time fee are listed exactly as quoted in the full ranking, never converted.
Are at-home clear aligners safe?
Clear aligners are FDA Class II medical devices (product code NXC). We show each brand's FDA device-safety record (its recalls and adverse-event reports) and how its treatment is supervised, so you can weigh safety and oversight, not just price. Moving teeth without proper supervision is the real risk to avoid.
How do you rank clear aligners?
We compare the axes that actually differ between brands: starting price and financing, typical treatment length, how treatment is supervised (remote, hybrid, dentist-led and in-office) and the brand's FDA device-safety record. The price order uses the monthly price a brand quotes in US dollars, or an approximate US-dollar equivalent kept for ordering only, and every figure links to its source. How we rank
