Chemical Formula: Na2PO3F
is used in toothpastes
to protect tooth enamel from attack by bacteria (cavities,
also known as caries).
It was developed to avoid infinging on the Crest patent for
The active part of the molecule is the fluoride ion, which
is why two other fluorine containing compounds,
and stannous fluoride are also used.
Like stannous fluoride, sodium monofluorophosphate
can be used with abrasives
that contain calcium, which prevents sodium fluoride from
Fluorides work in two ways. They reduce the ability of
