Invisalign alternatives: what is actually on the market

The alternatives to Invisalign fall into two groups, and the difference between them is not the plastic. One group is planned and checked in a dental chair; the other is ordered online, made from impressions or a scan you take yourself, and reviewed remotely.

Invisalign is a brand of clear aligner made by Align Technology, not a synonym for the treatment. Plenty of practices straighten teeth with other systems and never say the word.

The two shapes of the market

Chair-side aligners are prescribed, fitted and monitored by a dentist or orthodontist you sit in front of. Mail-order aligners are bought online, with the clinical review done at a distance from records you supply.

Everything else — price, wear time, how long a course takes, whether there are attachments — varies within both groups. Supervision is the axis that actually divides them, and it is the axis the regulators talk about. The US Food and Drug Administration's consumer page states that clear aligners "are prescription devices, meaning they are only safe to use under the supervision of a licensed practitioner, such as a dentist or orthodontist", and that it "has not authorized clear aligners that are marketed directly to consumers without supervision by a dentist or orthodontist".

Why the brand name is doing so much work

Invisalign has been advertised to the public for two decades, so it has become the word people use for the whole category — the way a vacuum cleaner gets called by a brand name. That matters when you shop, because searching for one brand's name returns that brand's marketing and the practices that pay to appear beside it, and hides the systems that never advertise at all.

It also matters when you read a price. A quote for "Invisalign" and a quote for a laboratory-made aligner course from the same practice are quotes for different products with different licence fees behind them, and a practice can usually explain what it is charging you for if you ask.

What is available from a dental chair

Your dentist or orthodontist will offer one or more aligner systems, and Invisalign is only one of the names on that list.

Align's own material describes the chair-side process: an intraoral scan, a plan built in the company's treatment software by the doctor, and then "a series of regular, face-to-face check-ups to give you each new batch of aligners and monitor the progress of your new smile". At the end, Align supplies its own retainers "or another retainer brand".

Candid is now in this group too, not by choice. It closed its consumer business in January 2022 and sells only through dental practices as CandidPro; if your dentist offers it, you are buying a practice's treatment rather than a mail-order box.

Practices also offer systems that never advertise to the public at all, including aligners made by dental laboratories to the practice's own prescription. Those have no consumer brand to search for, which is exactly why they rarely come up in a search like this one. Ask what your practice uses and why it chose it.

There is also the older, non-removable option, and it is worth putting on the table with your dentist rather than ruling out because it is less discreet. Whether it suits a particular case is a clinical question, and not one this site can answer.

What is still sold by post

Two sellers publish prices and ship aligners to your door. AlignerCo listed an all-day plan at $725 and a night-only plan at $925 on 24 September 2026, both struck through from higher figures, and says on its own site that "every plan is reviewed by a US-licensed dentist / orthodontist". NewSmile listed one plan at $1,095 the same day and says its aligners, retainers and night guards "are prescribed by licensed dental professionals as part of every case".

Both statements are the companies' own, quoted as such. Neither tells you whether anyone examined the mouth in question before the trays were made, which is the thing the FDA and the UK's General Dental Council both say matters. The GDC's position is that "at present, there is no effective substitute for a physical, clinical examination as the foundation for that assessment".

What is no longer available by post is the part most people remember. SmileDirectClub wound down in December 2023; Dentsply Sirona suspended Byte in October 2024 and confirmed in January 2025 that it was not bringing the at-home systems back. The dated record of those closures is worth ten minutes before you buy anything in this category.

Questions that separate the options better than price does

Ask these of any seller, chair-side or mail-order, and the answers sort the market faster than a price comparison.

1. Who is the treating clinician, by name? You should be able to write the name down and check it on a public register.
2. Has anyone examined this mouth in person, with X-rays, before a tray was made? Gum disease, decay and root problems do not announce themselves in a photograph.
3. What is included? Every tray in the course, refinements if teeth do not land where planned, and retainers afterwards — or only some of those?
4. How is progress checked, and what triggers a change of plan?
5. What happens if you stop trading? Three companies in this market have already answered that question the hard way.

The honest free answer

Before you compare any two sellers, book an in-person examination. No aligner seller pays us to say so, and it is the step that decides whether the comparison is worth making at all: the FDA lists "new or worsening dental pain", "jaw pain", "bite problems", "worsening tooth misalignment" and "new gaps between teeth" among the effects it associates with unsupervised aligner use, and an examination is what rules out the conditions that make those more likely.

If the examination is the thing you cannot afford, a dental school clinic or a community health centre usually charges less than a private practice for the same look inside your mouth.
