Sensitive teeth need tough toothpaste, but technology can also help. Researchers at the Indian Institute of Science (IISc) in collaboration with deep-tech startup Theranautilus have now engineered CalBots—magnetic nanobots that can penetrate deep into dentinal tubules, which are tiny tunnels in teeth that lead to nerve endings. These CalBots can then form durable seals for worn enamel, offering lasting relief from sensitivity in just one application. The study is published in Advanced Science .
