Abstract
The present invention relates to the problems of remineralization without demineralization of dental enamel by applying to the teeth a composition which is present in two phases which do not react with one another until introduced into the oral cavity. One phase contains at least one water-soluble calcium compound and the other contains at least one water-soluble inorganic phosphate and at least one water-soluble fluorine compound. In this way the ions which effect remineralization can be absorbed by the dental enamel and their subsequent reaction causes rehardening of demineralized areas in the dental enamel.
