Fluoride in toothpaste
The company I work for has decided, after a long history or producing non-fluoridated toothpastes, to have at least one fluoridated option. I will be using sodium monofluorophosphate 1000 ppm (0.76% w/w).
I understand fluoride isn’t particularly stable in toothpaste hence most brands only having two year shelf-life for their toothpaste.
Should I be adding an overage to account for fluoride loss over time and what sort of overage I should be adding?
