Faithful To Nature Biodegradable Dental Floss is a waste-free alternative to regular floss. Ordinary dental floss is typically nylon-based and packaged in a plastic dispenser. While floss is important to use daily for proper oral health, it is not recyclable or sustainable. Faithful to Nature has the solution, with a corn-derived PLA floss that’s completely biodegradable. It’s also packaged in waste-free, plastic-free materials, so you can rest assured every component is eco-friendly.
