How can hotel toothpaste wash so well?

Because the highest content component in hotel toothpaste is friction agent (about 25%-6%), which is used to strengthen the friction, detergency and polish the tooth surface of toothpaste. The friction agent should have a certain friction effect, but it can't harm the tooth surface and periodontal tissue, nor can it interact with the drugs in toothpaste. Especially, the friction agent in fluoride toothpaste should be compatible with fluoride ions and keep its activity. In addition, the fineness and particle shape of the friction agent will affect the quality of the paste.
