0 1 First of all, we need to know the basic knowledge of dental floss and cotton. Many people are no strangers to these two things. Loose meat is a kind of food we often eat, and I especially like to eat soft bread.

As for cotton, although we have no direct contact with cotton, we all know that our quilts are made of cotton, and the quilts made of cotton have a particularly good warm-keeping effect. It is worth emphasizing that cotton grows on trees.

As can be seen from the above two points, floss is an edible item, and its raw material is pork, beef or other meat, which will have the smell of burnt meat when burning.

The main component of cotton is cellulose, which is difficult to swallow, indigestible by human body and tasteless when burned.

It can be concluded from the above that there will be no cotton in dental floss, and some relevant departments have refuted this rumor. I hope you don't listen to rumors!
