What are Invisalign aligners made of?
Invisalign aligners use a medical-grade thermoplastic called SmartTrack™. Because Invisalign designed SmartTrack™ for orthodontic use, it feels flexible, durable, and comfortable.
- BPA-free: Invisalign makes SmartTrack™ without bisphenol-A (BPA).
- Latex-free: This helps if you have a latex allergy.
- FDA-approved: The material meets medical device standards.
In other words, SmartTrack™ supports safe, daily wear while still guiding tooth movement.
Why does BPA-free matter?
BPA is a chemical used in some plastics. Over time, it can leach into food or drink from certain containers. As a result, many people prefer BPA-free products for items used regularly.
Some studies link BPA exposure with health concerns, such as:
- Hormone disruption
- Higher risk of some cancers
- Development concerns in children
For that reason, Invisalign uses BPA-free materials so you can wear aligners daily with added peace of mind.
How safe are Invisalign aligners?
Invisalign designs aligners for everyday use. So the system focuses on both comfort and safety.
- Non-toxic material: SmartTrack™ does not release harmful chemicals during normal wear.
- Custom fit: We tailor aligners to your teeth, which means they usually feel smooth and controlled.
- Hygiene-friendly: You can clean aligners easily, so they stay fresh throughout treatment.
How to care for your Invisalign aligners
Good care keeps aligners clear, clean, and comfortable. To get the best results, follow these simple steps:
- Clean daily: Rinse and gently brush aligners with a non-abrasive cleaner.
- Avoid heat: Skip hot water and don’t leave aligners in direct sunlight. Otherwise, the plastic may warp.
- Store properly: Keep aligners in their case when you’re not wearing them. This way, you protect their shape and hygiene.
