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.
