The short answer: do not pick a teeth-straightening brand before a dentist or orthodontist confirms that your teeth, gums, bone levels, and bite are safe to move. The American Dental Association says orthodontic treatment should be supervised by a dentist or orthodontist, and the American Association of Orthodontists says clear aligners are not right for everyone. That means the best "brand" is usually the one paired with the right exam, records, monitoring plan, and fallback options if treatment does not track as expected.

Start with a dental exam, not a brand list
Orthodontic alignment is health care, not a commodity purchase. The ADA warns against direct-to-consumer dentistry because moving teeth without understanding the full oral condition can cause serious harm, including bite damage, gum problems, or tooth loss, on its direct-to-consumer dental services policy page and its 2023 reaffirmation. If you have pain, swelling, loose teeth, infection signs, or jaw symptoms, treat that as a dental care issue first; the ADA's dental emergencies guidance and pain and swelling guidance support getting qualified care promptly rather than trying to self-manage the problem.

Doctor-directed clear aligner systems
Invisalign
Invisalign is still the clearest mainstream choice if you want a conventional doctor-led aligner workflow. Its official process starts with a scan by a doctor, then regular face-to-face checkups, and the brand also says on its purchase guidance page that aligners are not sold online or in stores. Ask about attachment use, refinement policy, and retention before you compare logos.
ClearCorrect
ClearCorrect looks strongest when your clinician wants more treatment-planning control inside a professional workflow. Its official support content says the first appointment is for records collection and recommends informed consent, while the patient FAQ explains a 22-hour wear schedule and notes that treatment time depends on clinical goals and compliance on its patient FAQ page.
Spark
Spark is worth asking about if your orthodontist wants an aligner system built around office-based planning instead of a consumer-first workflow. Ormco's current pages position Spark as a doctor-directed aligner platform, and its treatment-options page shows product tiers from minor relapse cases to complex malocclusions. That makes Spark more relevant in an orthodontic consult than in a broad shopping search.
Practice-based systems that blend treatment planning and monitoring
SureSmile
SureSmile is useful when you want one brand family that can cover aligners, braces, and retainers under a doctor's supervision. The official site says a doctor can advise which mode is right for simple or complex cases, so it is a strong option when you are not yet sure that aligners alone are the right tool.
CandidPro
CandidPro is no longer the old direct-to-consumer Candid model. The company says treatment starts with a consultation and records, the plan is designed with a US-licensed orthodontist, and patients complete remote check-ins every 7 to 14 days. Its own newsroom also says it shuttered the direct-to-consumer business in 2022 and is now doctor directed.
Six Month Smiles
Six Month Smiles is best understood as a guided adult treatment model rather than a universal fix. Its current patient-facing site says it is aimed at adults 16 and up and offers invisible aligners or clear braces with an average treatment time around six months. That can make sense for limited cosmetic alignment, but you should ask directly whether your bite goals fit its shorter-treatment logic.
Braces systems still worth asking about
Damon
Damon matters because fixed braces are still more predictable than removable aligners for some movements and some compliance profiles. Ormco's current Damon pages position the system around self-ligation, and the Damon Ultima page emphasizes earlier rotational, angulation, and torque control. Ask about it if your orthodontist says your case needs fixed mechanics or tighter finish control.
Empower Clear
Empower Clear is not a consumer-shopping brand in the same way aligner companies are; it is an FDA-cleared ceramic orthodontic bracket from American Orthodontics. If your office offers it, compare it as a fixed-appliance option: how visible it is, how often wire changes happen, and whether your orthodontist prefers it over Damon or traditional brackets for your exact bite.
Remote-first brands that need stricter screening
ALIGNERCO
ALIGNERCO says every plan is reviewed by a US-licensed dentist or orthodontist, offers all-day and NightOnly wear, and markets average timelines around four to six months for eligible cases. The tradeoff is that its workflow is still remote first. If you compare it seriously, ask how your treating dentist is reached, what happens if trays do not seat, and whether you need an in-person periodontal evaluation before impressions.
NewSmile
NewSmile currently markets doctor-directed aligners, remote monitoring, and at-home impressions. Its clinical-operations material says it works with a network of licensed dentists and orthodontists, and its main aligner page says treatment includes remote monitoring and support. That makes it more structured than a no-doctor mail-order model, but it still deserves stricter up-front screening than a fully office-based case.
Brands to treat as unavailable or cautionary on August 30, 2026
Byte
Byte's official site says it has concluded operations. Separately, the FDA recall database shows an open recall record last updated on August 26, 2026 tied to concerns that its virtual-only workflow may not adequately screen out contraindicated patients. That combination makes Byte a poor choice for new treatment planning.
SmileDirectClub
The official SmileDirectClub customer FAQ says the company wound down global operations, that aligner treatment is no longer available through the platform, and that unshipped aligner orders were cancelled. It should not be treated as a normal new-patient option.
Questions to ask before you pay
- Who is legally responsible for your care, and how do you contact that clinician if trays do not fit or symptoms change?
- What records are taken before treatment: X-rays, photos, periodontal assessment, bite analysis, and scan?
- What happens if your case turns out to need braces, elastics, attachments, IPR, or refinements?
- How is retention handled after treatment, and what is the plan if your bite finishes short of the original simulation?
Bottom line
If you want the lowest-risk path, start with a dentist or orthodontist and compare Invisalign, ClearCorrect, Spark, SureSmile, CandidPro, Damon, or Six Month Smiles through that clinical relationship. Remote-first brands like ALIGNERCO and NewSmile may fit limited cases, but only after proper screening. As of August 30, 2026, Byte and SmileDirectClub should be treated as cautionary or unavailable, not as routine fresh-start options.
