New-fangled synthetic enamel could eliminate pain

Treating early tooth decay could become easier and less painful thanks to a discovery by Japanese scientists.

They have developed a synthetic tooth enamel that can repair early tooth decay without the need for drillings and fillings.

The crystalline white paste can reconstruct enamel without removing the decayed area. It repairs small cavities and helps prevent new ones.

The researchers warned the paste should not come into contact with the gums because it could cause inflammation owing to its high concentration of hydrogen peroxide.
