New magnetic nanobots could seal sensitive teeth for good: Study
Scientists at IISc Bengaluru, along with startup Theranautilus, developed magnetic nanobots designed to travel deep into dentinal tubules and seal the channels that cause tooth sensitivity. These bots, dubbed CalBots, deliver a specially formulated calcium silicate-based bioceramic cement that creates a durable plug, potentially providing relief from pain triggered by cold or hot stimuli.
