Whitening toothpaste does not bleach!

Whitening toothpastes are probably a waste of your money. They promise a Hollywood smile, but in fact after the use of these products can not see any effect, as the journalists have found British newspaper Daily Mail.

In Russia, the popularity of whitening toothpastes   It is constantly growing, because they are supposed considerably cheaper alternative to the classic bleaching in the dentist's office. Already 40% of adults express concern about the lack of snow-white smile. And most can not afford to pay a dentist, but to buy toothpaste (a little more expensive than usual) they may afford.

In Britain, this difference is more pronounced - whitening toothpaste here are, on average, 300% more expensive than traditional, though still inferior to the price of professional whitening. For example, ordinary toothpaste Aquafresh Fresh & Minty will cost 1 pound, and bleaching ISO-Active Whitening already in 3, 7 lbs. Journalists from the Daily Mail took a sample six of the most popular varieties whitening toothpastes   and subjected them to a thorough check.

Advertising promises that the pasta will make teeth whiter three colors, or "money back". However, clinical studies carried out by the manufacturer, indicates that only 39% of people meet the end result, and 43% did not observed "no improvement" in the use of the paste. Journalists recruited several women who regularly used different bleaching pastes. Invited as an expert dentist assessed whiteness of their teeth.

One month after the start of the experiment, none of the women had no noticeable discoloration of teeth, sufficient to be marked on a color scale expert. But manufacturers, which asked for explanations, journalists, researchers amicably accused of incompetence. Ostensibly observations were made in the "uncontrolled environment", and with the minimum of participants (one woman on each pasta). Therefore, they can not be called honest. (READ MORE)

The teeth will be healthier in 5 years

That's how much time it takes developers to artificial tooth enamel in order to release it to the world market. Japanese researchers from Kinki University have created a thin film, which protects the teeth from caries, removes them from the increased sensitivity and even whiten.

The thickness of the film - 0, 04 mm. It is completely invisible to the eye and is not perceptible in the mouth. The coating is not necessary to clean - coating does not stick to it, even during meals.

Artificial tooth enamel   made of natural material - hydroxyapatite (basic mineral contained in the enamel). It is abrasion-resistant and ultragibkoy. Due microporous air permeable saliva and teeth coated film can breathe. The only drawback of the invention -Duration process of fixing (the film is attached to a tooth during the day, and all the while the patient is forced to go hungry). However, the Japanese had promised to eliminate this deficiency.
At the moment, the scientists, led by Professor Shigeki Hontsu test their know-how on human extracted teeth. The next step - testing on animals. According to experts, synthetic enamel will be available in about 5 years. Information on the estimated cost of dental coverage is not reported.

For reference:
Superfine dental film is formed under the influence of laser hydroxyapatite compressed, placed in a vacuum chamber. As a result of the mineral sputtered individual microparticles, which are deposited on the salt crystals. Subsequently, the salt was dissolved in water and the solution was passed through filter paper.

6 familiar things spoils teeth

A national survey of American dentists, which was attended by over 700 dentists showed that the damaging effect on teeth are not only sugar and radical procedures like whitening. Tooth enamel, for example, greatly spoils the usual toothbrush.

Many people specially chosen for themselves a brush harder: it is assumed that hard toothbrush   It cleans the teeth better. Meanwhile, hard-bristled tooth brushing causes excessive sensitivity of the incisors - working hard hard toothbrush Together with the microbes can be easily removed and tooth enamel.

"When the protective tooth enamel is erased, it remains unprotected hard tooth tissue, known as the Dent - said Professor, MD Howard Wen College of Medicine in Georgia. - Dentin is directly linked to the nerve center of the tooth, located inside. And when Dent is unprotected, the nerve center becomes vulnerable to numerous stimuli. "

Tooth sensitivity is usually called erasure tooth, resulting in the exposure of the nerve endings. But that's not all. The expert says: aggressive cleaning not only do harm to the enamel, it also pushes the border of the gums, exposing the roots of teeth and making them look old. According to Professor Howard, brush with soft to medium hardness clean the teeth is not worse than with a hard-bristled brushes, without damaging either enamel or gums. The expert also recommends switching to desensitizing (reduces sensitivity) toothpaste and oral hygiene -use floss and brush your teeth twice a day for at least two or three minutes, holding the brush at 45 degrees and rotating it in the circumferential direction.

What else destroys teeth

The water from the tap . And much chlorinated water in the pool. Chlorination of water breaks its natural alkaline balance and makes dangerously acidic. After visiting the pool or brushing teeth chlorinated water dentists advise to use mouthwash containing fluoride.

Snacks. During a quick snack produced little saliva that cleans your teeth naturally. In addition, most people are carbohydrate snack food and quickly digestible carbohydrates break down into simple sugars: glucose, fructose, maltose, lactose, which are exposed to bacteria in the mouth to form plaque - a primary cause of dental caries and periodontal disease. By the way, along with dessert in the list of the most dangerous foods for teeth are present and bananas. Their flesh sticks to the interdental space and the inside of the gums, which collects a lot of bacteria, and thus accelerating their growth.

Diet soda.   It is dangerous as well as sweet drinks. Teeth port is not so much because of the sugar in these drinks, but because of their high acidity - in kolah contains citric acid and phosphoric acid. Soda should drink through a straw, and then immediately rinse your mouth with water. But it is better to stop drinking it altogether.

Oral contraceptives.   When oral contraceptives to visit a dentist to check teeth need to frequently - once every three months. Hormones that come with contraceptives in the body, can trigger a condition known as "periodontal infection" when the immune system can not compensate for the amount of bacteria that accumulate in the oral cavity. It is usually observed in pregnant women, who often lose their teeth, nurturing the child. Women who take oral contraceptives, it is also desirable to increase the intake of calcium and rinse your teeth more often, including antibacterial rinses.

Slimming.   Many of them contain substances that reduce salivation (this is the sensation of hunger). Lack of saliva leads to the fact that the acidity of the oral cavity increases, and the acid begins to erode dental enamel.

At the heart of a tool they immediately start pounding and it becomes very scary. A dentist should include drills, these women are afraid, the emotional equivalent of a load on the body of a powerful stress. But that's not all. Research specialists from Sydney found that women forty and over, especially react even to the common word "dentist" - it gives them an attack of panic. Trying to find an explanation for such a strong sense, experts have carefully studied the history of the disease and found a pattern: it turned out that visiting the dentist is particularly painful concern for those people who have experienced violence, personal injury.

Juices destroy children's teeth

Actively promoted "healthy" juices and smoothies fruit is not so safe for children's teeth, as many parents. Dentists warn that such beverages can not be carried away.

Doctors from the prestigious dental clinics in London that cater to families with large incomes in recent years have increasingly faced with young patients with rotten teeth. Doctors believe that this is due to the belief in parental benefits for all sorts of children's health fruit juices   (as fresh and preserved) and a variety of fruit-based drinks.

Dean of the Faculty of Dentistry of the Royal College of Surgeons Kathryn Harley argues that these drinks have damaging to enamel children's teeth   acidity. At first, under the influence of acid erodes the enamel, then begins to break away, then just tooth decay. Dr. Harley says a whole generation of children who refuse to drink plain water, as they are accustomed to from childhood fruit juices .

"The problem is that these children do not want to drink water, - says a leading British dentist. - They each time wants her saturated fruit taste. My colleagues are faced with parents who say," My child does not drink the water " . But if you teach a baby almost from the first months of life to fruit juices, is then weaned from these drinks will be difficult. "

According to Harley, extreme acidity of juices and fruit-based cocktails represents a significant threat to children's teeth . "Most people understand that sweet bad for teeth, but almost nobody thinks that acidic drinks are no less dangerous" - sadly concludes the doctor. Doctors recommend eating organic fruits and drinks from the priority given to plain water.

People will replace teeth fish beak

In the not very distant future, people may appear mouths like fish beak, scientists believe. This is due to the fact that human teeth are virtually useless.

fish beak

According to biologists of the University of Sheffield's Dr. Gareth Fraser, increase the length of human life and the modern diet consisting of "soft" consistency of products makes human teeth practically useless device. And as soon as they become an atavism, then after a number of generations even disappear, as has happened with tails, from which people were only the base - the coccyx.

fish beak

Dr. Frazier believes that instead of the traditional appearance mouth with teeth   a certain similarity   fish beak   in terms of evolution and human biology is absolutely correct. Moreover, in contrast to the teeth, the beak does not rot, crumbling and falling. Scientists call this evolutionary change "logical and practical."

But do not hurry because this forecast to abandon a visit to the dentist - turning mouth with teeth   at fish beak   It would take more than a few million years. So that the prospect awaits except our very distant descendants. This conclusion Dr. Fraser did when studying features of tooth formation in humans and animals.
