Do Invisalign braces contain Bisphenol-A (BPA)?
Invisalign braces do not contain Bisphenol-A or phthalate plasticizers. The Invisalign aligners and retainers are made from medical grade, high molecular weight, polyurethane resins. Clinical tests have been conducted to determine the biocompatibility of these materials. Studies do show that invisalign braces are biocompatible and pass all applicable regulatory requirements for wear in the mouth.
