Why is the hotel toothpaste washed so well?

Because the highest content in hotel toothpaste is abrasive (about 25%-60%), which is used to strengthen the friction, decontamination and polishing of tooth surface. The friction agent should have a certain friction effect, but it cannot 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 also affect the quality of the paste.
