Technical Field
The invention belongs to the technical field of daily chemicals, and particularly relates to stain-removing whitening toothpaste and a preparation method thereof.
Background
The causes of tooth staining, yellowing, are generally classified into endogenous and exogenous causes: endogenous staining is formed during tooth development, e.g., tetracycline is deposited in dentin, which causes the tooth to turn yellow, brown or dark gray, called tetracycline teeth; if drinking water contains too much fluorine, dental fluorosis can be caused, and tooth surfaces are in a chalk color and dark brown patches; hemoglobin can also blacken teeth if bound to bacterial breakdown products after tooth nerve death. The exogenous staining is caused by the existence of various bacteria on the tooth surface, which secrete a plurality of viscous substances on the tooth surface, food residues and soft dirt in daily diet, smoke stains, certain mineral substances in drinking water and mineral substances in human saliva are adsorbed on the viscous substances to form bacterial plaques and dental calculus, so that the teeth are gradually yellowed or blacked, and various oral inflammations are also triggered. Tooth brushing is the most important means for self-cleaning dental plaque and calculus, cleaning teeth, preventing tooth discoloration and periodontal diseases. At present, a lot of toothpaste with whitening allegedness exist in the market, for example, the toothpaste plays a role in whitening teeth by adding plant whitening ingredients, but the whitening toothpaste still has the problems of slow effect and unobvious whitening effect.
