People are always looking for ways to whiten their teeth and protect them from decay. While there are many toothpastes that can help accomplish this and improve dental health, there's still more that can be done. Recently, researchers from Japan announced that they have created a microscopically thin film that can cover each individual tooth, making them appear whiter while protecting them from decay.
The Agence France Presse (AFP) reported on the invention, which was something that dentists thought was only a dream.
"This is the world's first flexible apatite sheet, which we hope to use to protect teeth or repair damaged enamel," Shigeki Hontsu, professor at Kinki University's Faculty of Biology-Oriented Science and Technology, told the AFP. "Dentists used to think an all-apatite sheet was just a dream, but we are aiming to create artificial enamel."
It will be a few more years before this product is available on the market, but the researchers are very optimistic that it could be used for cosmetic purposes in as little as three years.
According to Dental Guide USA, 92 percent of adults between the ages of 20 and 64 have had tooth decay in their permanent teeth, which highlights the need for such a product.
