1. A composition for remineralizing teeth, comprising:
a) calcium phosphate (CaP) glass, and
b) aqueous silica (SiO2) sol;
wherein the composition comprises SiO2 sol 30-35% w/w, water 60-70% w/w, and CaP glass 2-3% w/w, based on the total amount of the SiO2 sol, water and CaP glass constituents, wherein the SiO2 sol contains 10-90% by mass SiO2 and the remainder water.
