The invention discloses 
chitin tooth protection 
toothpaste. The 
chitin tooth protection 
toothpaste comprises the following components in percentage by weight: 0.2 to 0.4 percent of 
chitin, 68 to 72 percent of 
sorbitol sugar solution, 14 to 16 percent of 
silicon dioxide, 2 to 3 percent of lauryl 
sodium sulfate, 1 to 1.2 percent of 
sodium carboxymethyl cellulose, 5.45 to 13.35 perecnt of de-ionized water, 0.25 to 0.35 percent of 
saccharin sodium, 0.15 to 0.25 percent of 
menthol, 0.9 to 1.1 percent of clove and 0.15 to 0.25 percent of nipagin ester. According to the chitin tooth protection 
toothpaste, the component, namely the chitin, which has the effects of stop bleeding, relieving pain, diminishing

human body is added initiatively, so that the chitin tooth protection toothpaste has the effects of preventing oral ulcer, swelling and aching of gum, bleeding and the like besides the function of cleaning the 
oral cavity of common toothpaste; chitin molecules contain polar groups, such as-OH and NH2<+>, so that the 
reproduction of harmful 
bacteria in the
