Dr Tung's Smart Dental Floss is a waxed, lightly cardamom flavoured floss that stretches to reduce harm to gums and fingers while reaching hard spaces. They use natural waxes unlike mainstream brands which often use petrochemical derivative, and it is clinically proven to remove up to 55% more plaque than regular flosses. Not tested on animals, does not contain silk, and packed in a biodegradable container which will biodegrade in a landfill in 3-5 years (instead of 100 years for regular plastic).
