Whitening toothpastes
First toothpastes were manufactured 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 of toothpaste, bleach as well as simpler, include a number of similar components:
- Abrasives – Abrasives vary and may include dicalcium phosphate, silicon oxide or aluminum oxide.
- Fillers – Fillers stabilize the toothpaste and make it thick. Often, natural substances, such as an extract from algae.
- Dyes – for the formation of various color of toothpaste used by natural and artificial dyes.
- Frothers – foaming agents help to remove plaque and food debris. Usually used for this purpose lauryl.
- Fluorides – sodium monofluorophosphate (0.76%), or sodium phosphate (0.24%), and other fluoride compounds are commonly used as a means of caries prevention.
- Food additives – additives with a taste of peppermint and curly, cinnamon and wintergreen toothpaste give it a wonderful flavor.
- Humidifiers – wetting agents such as sorbitol and glycerol are used to prevent drying of toothpaste.
- Preservatives – such components as metilparaban and propilparaban help prevent bacteria and fungi, extending thus the shelf life of toothpaste.
- Sweeteners – for sweetening the paste used saccharin, sorbitol, and others.
Has been published numerous studies describing the role of toothpaste, as an additional means to remove plaque, tartar and dark spots on the teeth. In recent years the focus is on toothpastes that whiten your teeth.
Whitening Toothpaste whitens teeth by brushing mainly due to the mechanical action of soft abrasive materials and / or activity of enzyme additives, for example – papaina2. It was shown that these components are effectively lighten (bleach) teeth by removing the accumulation of plaque, stains and painted plaque (3-5). In addition, the components have been developed that inhibit the growth of crystals and thus violate the compaction process of plaque to the state of tartar. It was discovered using materials such as 1,3% solution of pyrophosphate and 1,5% – copolymer, effectively inhibit the formation of dental stones.
It is important to emphasize that from the toothpaste is required to achieve tangible results without the use of coarse abrasives, which can abrade the softest part of the tooth simultaneously with the removal of plaque staining. Abrasive than toothpaste, the sooner there is a loss of natural tooth structure and restoring the surface. Abrasiveness of toothpaste should correspond to the minimum necessary to maintain the cleanliness of teeth. Thus, preferred for use are toothpastes with low abrasiveness and can effectively clean your teeth? Sparing? mode.
Consumers should be careful with toothpaste, which are highly abrasive, promote removal of colored stains and application of white pigments (titanium dioxide) for fast whitening effect. Interested dentists and consumers should contact the manufacturers of these pastes to obtain information about scientific developments, especially in the case of certain doubts in the mouth, which they use or recommend.
Now the market there paste containing a low concentration (1%) hydrogen peroxide. These products promise a delicious oral hygiene due to the oxidative effects of hydrogen peroxide. This action helps flush food debris that can accumulate between teeth and below the gum – in areas inaccessible by brushing. Bleaching effect in this case is achieved only after prolonged use and is not associated with oxidative action of hydrogen peroxide. Cleaning action of these pastes may eventually lead to tooth whitening.
Now become available products that combine low abrasive whitening gel and toothpaste containing the enzyme papain, and carbamide peroxide, which is used by dentists for home whitening. When using such a complex gel, toothpaste 10% peroxide is diluted to a final concentration of 3% hydrogen peroxide. Hydrogen peroxide is then decomposed into atomic oxygen and water. As a result, the area stained teeth are exposed to oxidation, allowing to enhance the whitening effect. Noticeable bleaching effect when using such retail 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 your teeth. However, scientifically proven effect of ash is minimal and is not documented in a proper degree in the dental literature.
More recently developed special toothpastes and rinses for adults have become available to consumers. These products are designed taking into account features pictures of adult oral cavity and provide oral hygiene, especially in areas of the mouth that are hard accessible. These pastes for adults have the ability to provide remineralization, brighten old and stained teeth, prevent cavities, while demonstrating a low abrasive, non-abrasive edge of the gums and composite fillings. In addition to the advantages of the rinser for adults struggling with the bacteria that cause bad breath.
