People use "Invisalign" for every clear aligner, even though several brands exist. Are they actually different, and does it matter which one you choose? Here's an honest breakdown.
The quick comparison
| Option | How it works | Supervision | Typical US cost* |
|---|---|---|---|
| Invisalign | In-office | Dentist or orthodontist visits | About $3,000–$8,000 |
| ClearCorrect | In-office | Dentist or orthodontist visits | Often similar to or below Invisalign |
| Spark | In-office | Orthodontist visits | Often similar to Invisalign |
| Direct-to-consumer | Impressions or scan, trays by mail | Remote | Usually lower |
*Prices vary widely by country, provider, and case complexity. Ask for a quote that includes refinements and retainers.
Invisalign
Made by Align Technology and on the market since the late 1990s, Invisalign has treated millions of patients. It has the most clinical history, a large network of experienced providers, and its own features like SmartTrack material and attachment designs.
Good for: a wide range of cases, including complex ones, with in-person supervision.
Trade-off: usually the most expensive option.
ClearCorrect
Owned by Straumann, ClearCorrect is one of Invisalign's main in-office competitors. The approach is similar: a provider scans your teeth, plans the movement, and supervises treatment.
Good for: mild to moderate cases where you want professional supervision, sometimes at a lower price.
Spark
Spark is made by Ormco, a long-established orthodontics company. It uses a material called TruGEN that the company says is clear and comfortable.
Good for: patients whose orthodontist offers it and who want an in-office alternative to Invisalign.
Direct-to-consumer aligners
These skip regular in-person visits. You take impressions or get a scan, a remote dentist approves a plan, and trays arrive by mail. They're usually cheaper.
Good for: mild cosmetic cases like small gaps or slight crowding.
Caveat: without in-person exams, problems like gum disease or bite issues can be missed, and they aren't suited to complex movements. The market has also been unstable: SmileDirectClub, once the largest brand, shut down in December 2023.
What matters more than the brand
Your wear time. The best aligner in the world won't work if it lives in its case. Whatever brand you wear, the basics are the same:
- Wear them 20–22 hours a day
- Switch trays on schedule
- Keep teeth and aligners clean
- Go to check-ups and wear your retainers afterward
Track it instead of guessing
TrackMyAligners logs your wear time with one tap, reminds you when aligners are out too long, and tells you when to switch trays. Free on iPhone.
So which should you choose?
For crowding, rotations, or bite problems, choose an in-office option supervised by an orthodontist. For a mild cosmetic case where cost matters most, a remote option can work, as long as you understand its limits and ideally get an in-person evaluation first. Whatever ends up in your mouth, tracking your wear time is the one variable fully in your control.
Frequently asked questions
Is Invisalign better than other clear aligners?
Invisalign is the most established brand with the most clinical experience, but ClearCorrect and Spark are also prescribed by orthodontists and can give similar results. The provider's skill and your wear time often matter more than the brand.
Are at-home aligners safe?
They can work for mild cosmetic cases, but without in-person exams some problems can be missed. Many orthodontists recommend at least an in-person evaluation before starting. SmileDirectClub, once the biggest at-home brand, shut down in December 2023, leaving many customers without support.
Do all clear aligners need to be worn 22 hours a day?
Most do, typically 20–22 hours. A few systems are designed for nighttime wear only; follow the instructions for yours.
