This review analyzes and systemizes results from publications on the solubility and hydrolysis of ammonium hexafluorosilicates (AHFS). These inorganic compounds have a variety of technological applications and have been actively researched as potential anti-caries agents in recent years. The characteristics of AHFS solubility were examined in water, methanol, ethanol (96%), and dimethyl sulfoxide. Existing approaches were discussed to interpret the main trends in changes of salts solubility depending on cation structure. Interionic H-bonds were noted to have a non-trivial negative impact on the water solubility of AHFS. The hydrophobic effect of H-bonds also needed to be considered when searching for new pharmaceutical substances among AHFS. A high, often close to quantitative, degree of hydrolysis of AHFS was found in diluted aqueous solution, resulting in an effective release of fluoride ions with caries-preventive properties.
