phosphosilicate

See also the bioactive glass compounds BioMin (fluoro calcium phosphosilicate) and NovaMin (calcium sodium phosphosilicate), which come in toothpastes that also include fluoride to cover all the bases.

And -ish, Novamin is calcium sodium phosphosilicate, similar in concept as another remineralizer but not quite the same.

It's a calcium sodium phosphosilicate that attaches to your teeth and eventually regrows into basically real bone.

How does NovaMin / calcium sodium phosphosilicate compare to toothpaste with nanohydroxyapatite in it?

Novamin is Bioglass 45S5 or calcium sodium phosphosilicate[1] which is not the same thing.

Novamin is Calcium Sodium Phosphosilicate as the active ingredient.

I once read an off hand comment[1] from a dental scientist on Reddit that NovaMin® (calcium sodium phosphosilicate) was shown with strong evidence to reverse tooth decay and promote remineralization but due to complex licensing issues was made OTC in Sensodyne toothpaste everywhere but the USA.

Here's how wikipedia describes it: "Bioactive glass: Newer Sensodyne products contain calcium sodium phosphosilicate (brand name NovaMin).

Humble old fluoride seems to work better than fancy calcium sodium phosphosilicate (also known as NovaMin): "The purpose of this in vitro study was to evaluate the effect of toothpastes containing sodium fluoride in different concentrations or a calcium sodium phosphosilicate system on pre-softened dentin demineralization and remineralization.

> Other products have popped up such as BioMin, a toothpaste that contains Fluorocalcium Phosphosilicate.
