TOOTHPASTE COMPOSITION FOR HYPERSENSITIVE-TEETH CONTAINING NANO-SIZED CARBONATE APATITE

摘要

The present invention relates to a toothpaste composition containing nano-sized carbonate apatite particles, which alleviates pain in patients with hypersensitive-teeth (cold temperature sensitivity), and provides a toothpaste composition for hypersensitive-teeth containing an active ingredient prepared by mixing silica and carbonate apatite particles with an average diameter of 1nm~500nm, in a weight ratio of 1:0.5 to 20. According to the present invention, nano-sized carbonate apatite particles mixed with abrasive silica in an appropriate mixture ratio, effectively coat a tooth surface by resealing exposed dentinal tubules, have a high safety level as their physical and chemical composition is identical to that of teeth, and form a coating on the surface of teeth by simply brushing, and can therefore be used effectively by a person with damaged enamel.
