The first toothpastes were made in ancient Egypt and consisted of a mixture of vinegar and pumice. And although modern whitening toothpastes have a complex composition and include many different components, all toothpastes, whitening as well as a simple, include a number of similar elements:

  • Abrasives (From the Latin "Abrasio" — scraping, scraping) can vary and can include dicalcium phosphate, silica or aluminum oxide.
  • Fillers stabilize the tooth paste and make it thick. Often used natural substances such as extract of seaweed.
  • For the formation of various colors of toothpaste used natural and artificial Dyes.
  • Foaming agents help to remove plaque and food debris. Usually used for this purpose lauryl.
  • Fluoride: Sodium monofluorophosphate (0.76%) or sodium phosphate (0.24%), fluorides and other compounds normally used as a means of preventing dental caries.
  • Flavorings with taste of peppermint and curly, cinnamon and pine needles give her a taste of the toothpaste.
  • Humidifiers— Humectants such as sorbitol and glycerin are used to prevent drying of toothpaste.
  • Preservatives— Component such as metilparaban propilparaban and help prevent bacteria and fungi, extending thus the shelf life of the toothpaste.
  • Sweeteners: Pastes are used for sweetening saccharin, sorbitol, etc.

Whitening Toothpaste whitens teeth mainly due to the mechanical action of soft abrasives, and / or activity of the enzyme supplements. In addition, these components effectively clarified (bleached) teeth by removing plaque, stained plaque and stains. There are special components, which inhibit the growth of crystals and thus disrupt the seal of plaque to the state of tartar. For example, use of materials, such as 1.3% sodium pyrophosphate and 1.5% — copolymer, effectively inhibit the formation of tartar.

Dentists estimate that between toothpastes required to achieve noticeable results without the use of harsh abrasives, which simultaneously with the removal of plaque staining can abrade the softest part of the tooth. What abrasiveness of toothpaste, the more likely is a violation of the natural tooth structure. Abrasiveness of toothpaste must meet the minimum required to maintain the cleanliness of the teeth. Thus, it is better to use toothpastes that have low abrasiveness and able to effectively clean teeth gently. Consumers should be careful with toothpastes that have a high abrasion, advertise remove color stains and application of white pigments (titanium dioxide) for a quick whitening effect.

Currently on the market there are pastes containing low concentrations (1%) hydrogen peroxide. According to the manufacturers, such pastes provide a more thorough oral hygiene due to the oxidative effects of hydrogen peroxide. This substance helps to wash away food debris that accumulate between the teeth and under the gum in hard to reach areas a toothbrush. Bleaching effect in this case is achieved only after prolonged use, and is not associated with an oxidizing action of hydrogen peroxide. Prolonged use of these pastes can eventually lead to a brighter teeth.

Become available as products that combine low abrasive whitening gel and toothpaste. They contain papain enzyme and carbamide peroxide is used for bleaching household. Noticeable effect when using these products has been marked as dentists and consumers.

Baking soda is also a popular component of a number of so-called whitening toothpastes. Consumers often think that baking soda can whiten teeth. However, scientifically proven effect of soda is minimal and is not documented in the dental literature.

Experts do not recommend ever use bleach, as they increase the sensitivity of teeth, and they begin to react strongly to the cold and hot. Whitening toothpaste should not be used more than twice a week.
