what are the needy things to make tooth paste?
Toothpaste is a paste or gel dentifrice used with a toothbrush as an accessory to clean and maintain the aesthetics and health of teeth. Toothpaste is used to promote oral hygiene:
In addition to 20–42% water, toothpastes are derived from a variety of components, including three main ones: abrasives, fluoride, and detergents.
Abrasives
Abrasives constitute at least 50% of a typical toothpaste. These insoluble particles help remove plaque from the teeth. The removal of plaque and calculus helps minimize cavities and periodontal disease. Representative abrasives include particles of aluminum hydroxide (Al(OH)3), calcium carbonate (CaCO3), various calcium hydrogen phosphates, various silicas and zeolites, and hydroxyapatite (Ca5(PO4)3OH).
Abrasives, like the dental polishing agents used in dentists' offices, also cause a small amount of enamel erosion which is termed "polishing" action. Some brands contain powdered white mica, which acts as a mild abrasive, and also adds a cosmetically pleasing glittery shimmer to the paste. The polishing of teeth removes stains from tooth surfaces, but has not been shown to improve dental health over and above the effects of the removal of plaque and calculus.

Fluoride has long been seen as a useful part of dentistry because it actively strengthens the enamel which coats teeth. Enamel is a hard substance which helps defend teeth from the attacks of plaque which otherwise would cause cavities to form and the nerves inside teeth to be interfered with. The use of fluoride has been shown to reduce instances of tooth decay by between forty and sixty per cent by strengthening the enamel on teeth.

Many, although not all, toothpastes contain sodium lauryl sulfate (SLS) or related surfactants (detergents). SLS is found in many other personal care products, as well, such as shampoo, and is mainly a foaming agent, which enables uniform distribution of toothpaste, improving its cleansing power.
