In sort of far-out-there, futuristic smile news, researchers in Taiwan have developed a new material that they claim can actually rebuild teeth, while reducing sensitivity.
The material, which the researchers applied to teeth as a paste (it’s a mix of calcium and phosphorus), has the ability to fill in holes or pores in worn teeth and actually builds new molecules in them, thus reducing sensitivity. While this has been done before, what makes this particular discovery different is that this substance goes deeper into holes and shows the potential to actually repair damaged enamel and provide longer-lasting relief from tooth sensitivity.
So what does this mean for those who suffer from tooth sensitivity—or, in a more beauty-related link, worn out teeth and receding gum lines that contribute to an aged appearance?
“There have been a number of new products aimed at alleviating sensitive teeth, especially around the gum line where receding gum tissue leads to exposed nerve endings,” explains Atlanta cosmetic dentist Ronald Goldstein, DDS. “Most of these products help for various time periods, but emphasis is now based on nanotechnology that provides greater ability of these agents to penetrate dentinal tubules. I predict 2015 will see further gains in this effort.”
