being a Geologist myself, i'm continually Surprised by the unceasing use of Silica in Toothpastes ! Silica, also hydrated silica is 'Silicon dioxide', Quartz, is basically a hard-rock mineral with hardness of 7 on Mohs scale, and tooth enamel is apatite with hardness of 5, so silica will aggressively abrade the softer teeth,
Many types of toothpaste are. highly abrasive and actually strip away tooth enamel which never grows back. The teeth may become. sensitive when tooth enamel is worn away. Toothpasteâs abrasiveness is measure by its Relative Dentin. Abrasivity (RDA). The table below shows the RDA of some common toothpastes. We suggest that you. use toothpastes with lower RDA ratings. In addition to finding toothpaste that is minimally abrasive, we suggest finding one with fluoride. Fluoride helps strengthen enamel and prevent cavities.
