I would have assumed that there was nothing that can be done to improve dental floss. Minty flavored string on a roll. The end. However, Radius, makers of ergonomic toothbrushes, have managed to improve the boring task a bit. Their naturally anti-bacterial floss is coated with 100% pure cranberry essence, so as it’s deposited on your teeth, it continues to inhibit bacteria growth even after you’re done. It’s spun in beeswax to help slide in tight spaces, uses no artificial or synthetic ingredients and comes packaged in recycled materials. Sounds like a fine upgrade to me.
