Invisalign, like any other dental treatment, has some environmental impact, but it is generally considered to have a lower environmental impact compared to traditional braces. The aligners are made from durable and flexible medical-grade plastic, which can have implications for resource consumption and greenhouse gas emissions. Precision manufacturing and digital processes help minimize waste, and energy-efficient technologies are used.  Disposal should be done as medical waste, and while aligners are not easily recyclable through regular programs, some dental offices may have specialized recycling options.  It's recommended to consult with your orthodontist for proper disposal guidance. Efforts are being made to improve sustainability and waste management in dental treatments.
