Toothpaste

Fluoride Additives in Toothpaste

Fluoride ions also help maintain the strength of the enamel. Fluorides are present in toothpastes largely in the form of stannous fluoride (SnF2, Fluoristan), sodium monofluorophosphate (Na2PO3F), and sodium fluoride (NaF).

* replacing some of the hydroxyl groups in the enamel's hydroxyapatite, converting it to a harder mineral, fluoroapatite, which is more resistant to erosion by acids, and

* suppressing the bacteria's ability to generate acids.

Although not our principal protection against tooth decay, the surfactants of toothpaste formulations do not effectively remove loose debris from the mouth and also gives us the sense of cleanliness. Almost all dentifrices contain a bit of saccharin and some flavoring or fragrance to leave us with a sense of sweetness and freshness after brushing.
