The claimed composition contains cation-modified silicon dioxide in quantity from 0.01 wt % to 30 wt % of the composition weight, where cation-modified silicon dioxide contains silicon dioxide, covalently bound with positively charged peptide, or where cation-modified silicon dioxide contains silicon dioxide, covalently bound with silane, where silane contains the primary and secondary aminogroup, and their combinations. The composition is preferably made in a form of toothpaste. As positively charged peptide polylysin can be applied, as silane - (3-aminopropyl)-triethoxysilane, (3-aminopropyl)-diethoxy-methylsilane, (3-aminopropyl)-dimethyl-ethoxysilane and their combinations.
