Invisalign is such a big name in clear aligner therapy that many people don't even know other options exist. The company has driven the industry for decades, but their aligners can be expensive. Fortunately, other innovative clear aligner brands have built on Invisalign's wildly successful model to deliver even more convenient or cost-conscious treatments. For adults who like the idea of straightening their teeth with near-invisible appliances, but aren't sure if Invisalign is right for them, here are several affordable alternatives.

Founded in Melbourne in 2022, Linea has taken the versatility and hands-on care of Invisalign and added the convenience of remote monitoring. Patients start their treatment with a couple trips to the dentist's office, where they'll get a thorough exam, intraoral scans, and IPR or attachments (for complex misalignments). Then, they'll complete virtual check-ins from home, so that Linea's clinical team can make sure their teeth are moving as expected and provide any necessary feedback and support. Plus, they have flat-rate pricing that's often much less than Invisalign.

If you like the reassurance and robust care that comes from in-person treatment, but worry about paying too much or making a lot of office visits, Linea might be perfect for you. Get started here.
That's right. The company who created Post-Its and Scotch tape has a clear aligner brand. As a leading materials company, they've developed two custom plastics (each with different advantages) that the orthodontist can switch between depending on your needs. They also have proprietary attachments that they say are exceptionally precise. Combined, they give your dentist plenty of room to customize your treatment.

Cons of 3M Clarity
If you want the expertise of an orthodontist and multiple top-grade materials—and you're willing to pay a little more for it—3M Clarity might be a good option.
Spark is another clear aligner brand from an influential, multinational company. Their manufacturer, Ormco, has been developing orthodontics products for over 60 years and serves orthodontists in more than 130 countries. Spark says their biggest advantage is their TruGEN material, which they claim is clearer, more comfortable, and more stain resistant than other plastics—although there aren't yet any outside studies that confirm it. Like Invisalign, they can incorporate buttons, elastics, and other attachments to handle complex misalignments.

Like the idea of ultra-clear and comfortable aligners from a well-established manufacturer? It might be worth considering Spark.
SureSmile has been around longer than most clear aligner brands, although they haven't always made clear aligners. In 1998, they started by producing archwires for lingual braces, and they pivoted to aligners in 2007. They follow the same model as Invisalign, so their treatment can correct a wide range of misalignments and involves in-person check-ups throughout the process. However, they can be less expensive since they charge dentists less in lab fees.

Cons of SureSmile
Anyone who wants robust in-person oversight and extras like the VPro, without paying Invisalign prices, might be interested in SureSmile.
Australian Smile Clinics are dentist-owned offices that offer only one treatment: Clear aligners. They have locations in Sydney, Melbourne, and Brisbane, where patients can get aligner treatment at lower prices than many other places, with payment plans available. They don't specify which brand of aligners they use, or if they can utilize attachments, but they say that they employ remote monitoring so that patients don't have to make as many office visits. Yet they only have three locations, so not everyone will have an office nearby.

Cons of Australian Smile Clinic
Anyone who wants low, flat-rate pricing for clear aligners—and doesn't mind potentially travelling farther to an office—may find Australian Smile Clinics intriguing.
ClearCorrect is one of Invisalign's longest-standing competitors, and since 2006, they've come up with some innovations of their own. Like some of the other options on this list, they're a fully in-office treatment. However, they also have several pricing options, and those prices can be slightly lower than Invisalign.
Pros of ClearCorrect
Cons of ClearCorrect
SmilePath is a fully remote alternative, so they don't require any office visits—even for the initial consultation. As a result, their prices are much lower than many other brands. While that might seem attractive, it also means that their treatment can only mild-to-moderate cases, and there's no in-person oversight to address issues that might arise. This leaves more room for error and a less safe treatment.

Cons of SmilePath
We get it. So many choices can be overwhelming. The most important tip we can give is to consult your dentist before deciding. They can tell you which treatment might work best for you, and whether you have any cavities, gum disease, or other issues to address first. We'd suggest sticking with a brand that requires in-office oversight from a dentist or orthodontist. That way, you can be confident you're getting a safe, effective, and expert-directed treatment.
Among the brands that incorporate in-person care, Linea is one of the easiest and most affordable, with flat-rate prices that beat Invisalign and many other competitors.
