The present invention relates to methods and compositions for exchanging ions in dental enamel. The teeth may be hardened and become more resistant to acid damage if treated with a composition that allows mineral supplementation and demineralization of minerals present in the teeth, for example by an aqueous oral care composition for demineralization and mineralization of at least one tooth, comprising: a source of calcium; a phosphate source; a fluoride source, preferably wherein the fluoride source provides a fluoride ion concentration of less than about 100 ppm, more preferably wherein the fluoride source comprises sodium fluoride, stannous fluoride, sodium monofluorophosphate, fluorinated amine, or a mixture thereof; at least 75% water by weight of the oral care composition; wherein the composition is supersaturated with respect to octacalcium phosphate, the composition having a viscosity of greater than about 2.75-log ([Cat; 2 + gt; ] * [P04lt; 3gt; ]) value, and the composition has a pH of from about 5 to about 6. Ion exchange in hydroxyapatite into fluoride or other metal ions can result in the teeth being more resistant to chemical and physical infringement.

The invention discloses an oral care composition containing baking soda, application thereof and toothpaste containing baking soda. The oral care composition is composed of baking soda, sodium phytate and sodium fluoride according to the weight ratio of 1:(0.04-0.1):(0.01-0.024). The oral care composition is high in stability, can neutralize dental plaque acid and whiten teeth, and can be matched with other carrier components to prepare various oral care products. The toothpaste containing baking soda has high stability and can deeply clean the oral cavity, whiten and strengthen teeth and nourish gingivae.
