Researchers in London have received the materials science Venture Prize for developing toothpaste made with special glass particles aiming to repair tooth decay.
The toothpaste contains special biodegradable glass, known as bioglass. It has the ability to retain calcium and phosphate when in a toothpaste but releasing them when in contact with moisture such as saliva in the mouth. Once the toothpaste is applied onto the teeth, the particles fill in areas of damaged enamel and dissolve in the moisture in the mouth. It was reported that the toothpaste can form a new surface on the teeth in less than three hours and the particles will dissolve completely in under eight hours.
Calcium and phosphate are crucial components of tooth enamel. It is expected that the tiny glass particles in toothpaste may half decay and help with sensitive teeth. The product is hoping to be launched in the next two years.
