Everyone is dreaming of having beautiful and white teeth. White teeth are a sign of a healthy body. A wide open smile helps to locate others around. In addition, it is a sign of prosperity and success.
Back in ancient times, people cleaned their teeth with ashes, soda or chalk. Now there are many ways to give dental enamel dazzling whiteness, both at home and in the clinic.
The easiest and most accessible option for everyone is to buy a whitening toothpaste.
Of course, you should not expect from the paste the same degree of bleaching, as for example, from chemical clarification or the procedure carried out with ultraviolet, but 1-2 shades make the lighter shade of the tooth with the help of quality pastes very real.
Tooth whitening tooth whitening toothbrush toothpaste can be mechanical and chemical.
These agents contain large enamel enamel particles( silica or calcium carbonate) that remove yellow plaque. The principle of their work can be compared with a facial scrub.
Naturally, large particles of abrasive are more effective, but their effect on enamel is stronger.
More recently, the safest materials have been found for mechanical bleaching.
This abrasive is papain obtained from papaya fruits and bromelain, made from pineapple juice, which brightens the enamel by dissolving the protein from which the plaque is composed.
Pastes with natural abrasives, for example, sea salt, are very aggressive.
Such pastes act on plaque and enamel with the help of hydrogen peroxide or a more modern variant - urea, clarifying plaque.
In addition, there are pastes with other chemicals that lighten the teeth by removing the pellicle. This is the thin organic film that appears on the tooth in the process of life and protects the tooth from the effects of microorganisms on it.
Preventive whitening pastes prevent the formation of plaque after professional clinical cleaning.
Used to prolong the effect due to crystallization inhibitors. Simply put, do not give dental deposits to form on the tooth.
It should be noted that in addition to the fact that the paste can make teeth and gums excessively sensitive and change the color of the seals, aggressive abrasives can change even the structure of the tooth and thinen its enamel.
Individual components of pastes can cause allergy and swelling of the gums.
Do not use toothpastes for bleaching people with periodontal disease and dental caries, as applying them can lead to deterioration of the teeth.
At the same time, the paste not only can return a natural shade to the teeth, but also dissolve tartar. To do this, the composition should include polyphosphates, but such pastes are again not recommended for people with hypersensitive teeth.
Abrasive particles can be from 20% to 40% of the toothpaste composition. Abrasives are the smallest particles that polish the tooth enamel and thus brighten it. RDA is an index determining the quality and quantity of abrasive, as well as the degree of cleaning and the effect of toothpaste on tooth enamel.
The following RDA indices differ:
In addition to bleaching agents( abrasive or chemical components), the following components are distinguished in toothpastes:
When buying a good whitening toothpaste, the following components should be avoided:
The experiment was carried out by the ROCS mark, the essence of which was that 3 groups of 20 people without periodontal diseases, for a month in the morning and in the evening, brushed their teeth with whitening toothpaste.
In order for all subjects to be on equal terms, the same toothbrushes were issued and a special diet was prescribed, excluding products staining tooth enamel. Also, all the subjects underwent professional dental cleaning.
The first group used a paste that clarifies the enamel by combining calcium with phosphorus, the second - paste with aluminum lactate, the third - with carbamide peroxide.
After the test period, 80% of the first group, 35% of the second and 85% of the third group noticed a visual effect of whitening, as well as a feeling of "smooth" teeth.
Based on the results of the evaluation of the special apparatus, the spectrophotometer, the teeth of the subjects of the first group became lighter in 75% of cases, in the second - in 45%, in the third - by 80%. On average, the subjects' teeth became whiter by 2 tones.
The best results were shown with pasta with carbamide peroxide, the teeth of the participants using the paste on its basis became whiter by 3 tones, but the number of subjects with hypersensitivity of teeth increased 2 times.
Two months after the end of the experiment, a second examination was conducted, the results of which showed that when the use of the paste was stopped, the effect of whitening became weaker. When examined after three months, the whitening effect completely disappeared.
Decide on which toothpaste best whitens teeth, but having studied the rating and consumer feedback about whitening pastes, you can make your choice deliberately.

I am a dentist and advise my clients to use Splat paste. It really gently removes plaque without damaging the enamel and gives an excellent visual effect of a snow-white smile.
Natalia, 32 years old
I always dreamed of a "Hollywood smile", but by nature my teeth are not particularly white. I tried a bunch of whitening pastes, but I did not see the special effect until I cleaned it - yes, my teeth are slightly lighter, and when you stop, everything goes back, if it does not get worse. But I'll still try new products, I really want white teeth.

In general, the use of whitening pastes makes sense when the color of the enamel is initially quite light and there are no diseases of the oral cavity.
You should also pay attention to the composition of the paste and choose a more gentle whitening, albeit slower. Do not think that the paste will solve the problem right away, but it will definitely help prolong the effect of professional cleaning and clinical bleaching.
