| Various embodiments of the invention include systems and methods of generating nano-sized salt particles. These methods include generation of a supersaturated solution of a salt MX by mixing of salts MY and NX in which the solubility of MX is lower than that of MY, NX or NY. In some embodiments, nano-sized particles of MX are grown further by further adiabatic addition of salts MY and/or NX. In some embodiments, MX includes potassium nitrate. Some embodiments include compositions of MX configured for use in treatment of dentine sensitivity. | ||||||
