DENT Brilliant More W Natural Peppermint Sample Size 20g x 10 [Product Introduction] From the conventional whitening method of "scraping off" stains, to whitening by "lifting" and removing them with the power of chemicals. Newly formulated with "sodium pyrophosphate," a chemical stain removal ingredient that lifts stains from the tooth surface. The lifted stains are then thoroughly removed by the cleaning function of the toothpaste and brushing. A whitening toothpaste that has evolved self-care whitening. ▼What are stains? Stains are formed when pigments such as tannins and polyphenols accumulate on the enamel surface from the consumption of coffee and tea. Stains (-) and calcium ions (+) on the enamel surface are firmly bonded by ionic bonds, making them difficult to remove with a toothbrush alone. ▼Brilliant More W is recommended for people who: ・Are concerned about tooth discoloration from coffee, tea, etc. ・Want to maintain the whiteness of their teeth after PMTC or whitening. ・Are concerned about stains during or after orthodontic treatment. ・Usually use gel-type toothpaste. ▼It says "lifts and removes stains," but what is the mechanism? "Sodium pyrophosphate" and "sodium polyphosphate," which are added as cleaning aids, sever the ionic bonds that strongly bind the stain to the tooth surface, lifting the stain from the tooth surface. The lifted stains are then thoroughly removed by the cleaning function of the toothpaste and brushing, revealing the natural whiteness of the teeth. It is important to brush away the lifted stains. ▼Whitening toothpastes often have a high abrasiveness, but does Brilliant More W also have high abrasiveness? If you try to remove stains only with physical force, the abrasiveness tends to be high. Brilliant More W contains "sodium pyrophosphate" and "sodium polyphosphate" (cleaning aids), which chemically lift stains from the tooth surface, so it exhibits excellent stain removal power without excessively increasing abrasiveness.
