A new toothpaste for relieving tooth sensitivity has been developed by UCL researchers using a nature-inspired material that supports bone regeneration. The technology, developed by scientists at the UCL Centre for Nature-Inspired Engineering (CNIE), includes a material originally developed for bone grafting, called AeroGraft, with a novel structure that can rapidly rebuild tooth surfaces with material indistinguishable from bone. Unlike most sensitive toothpastes, which work by either numbing
