Name the minerals found in Toothpaste
Calcium carbonate
This common abrasive help to remove plaque, debris and surface stains. Abrasives, combined with the scrubbing motion of your toothbrush, clean the surface of your tooth. They’re the reason your teeth feel so smooth and clean after brushing. They can also help make your smile whiter.
Besides calcium carbonate, other types of abrasives in toothpaste include dehydrated silica gels, hydrated aluminium oxides, magnesium carbonate, phosphate salts and silicates. These abrasives are rough enough to get the plaque off, but gentle enough to avoid damage to your enamel.
Silica
Minerals such as silica and are found in toothpaste and provide the coarseness that scrubs the teeth clean.
Aluminum Oxide
The coarse scrubbing action of toothpaste can come from aluminium oxide and other phosphate minerals.
Titanium Dioxide
Titanium dioxide, which is made from the minerals ilmenite, rutile and anatase, is present in toothpaste.
Ilmenite (FeO.TiO2) and rutile (TiO2) are the two chief minerals of titanium.
Titanium dioxide occurs in polymorphic forms as rutile, anatase (octahedrite).
This gives the toothpaste its white pigment.
Mica
Sparkles in toothpaste are made possible by the presence of mica, which is found in rocks.
Fluoride
Fluoride found in toothpaste is derived from the mineral fluorite.
It is used to help reduce cavities.
