CalBots: Nanorobots target tooth sensitivity at the source

Researchers at India’s IISc, in partnership with Theranautilus, have developed magnetic "CalBots"—400-nm bioceramic nanobots guided into dentinal tubules by magnetic fields. Once there, they self-assemble into durable plugs that recreate the tooth’s natural barrier, offering durable relief from sensitivity. In studies, mice treated with CalBots showed 100% behavioral recovery, effectively drinking cold water again after treatment. Because nearly 25% of the global population suffers from dental hypersensitivity, this innovation could greatly improve quality of life with just a single application
