An Ancient Thread with a Modern Purpose
SINAMARK® is the purveyor of 100% natural silk floss sourced from China
and it doesn’t belong in our bodies.
STRONG
Crafted from 100% natural silk, one of nature’s strongest fibers by weight, for durability during normal flossing. Coated with natural Candelilla wax to help the floss glide smoothly between teeth and enhance durability.
LAB TESTED
In vitro laboratory testing conducted at the University of Nevada, Las Vegas School of Dental Medicine evaluated the ability of waxed silk floss to remove plaque biofilm from a laboratory model. The testing demonstrated removal of plaque biofilm under the study conditions. Laboratory results do not necessarily predict results during everyday use, which may vary depending on flossing technique and individual oral health. The American Dental Association recommends daily interdental cleaning, including flossing, as part of a regular oral hygiene routine.
FLOSS MADE FROM 100% NATURAL SILK
SINAMARK® floss is made from 100% natural silk fiber from Bombyx mori silkworms. Silk is a natural protein fiber. The rate at which it biodegrades depends on composting conditions and may take many months in a home compost environment. Check local composting guidance before composting used floss.
