Expert Verdict

Same fluoride toxicity concerns as magnesium fluoride. Additionally, fluorosilicate salts may have slightly different toxicological profiles due to the silicate component; ingestion should be strictly avoided.. Dual fluoride-silicate structure provides both anticaries fluoride activity and mild abrasive/polishing characteristics from the silicate moiety.
