These tiny channels, named dentinal tubules, lead to sensitive nerve endings and are exposed due to enamel erosion and.or guys recession.  Once that happens, cool or warm liquids or food can reach these nerves and trigger intense dental pain.The nanobot plugs delicately seal these tubules stop these painful episodes.  Tests on extracted teeth show that the nanobots create tubule plugs in about 20 minutes.  Preclinical tests using mice reveal that this dentinal tubule plugging strategy effectively and completely insulates teeth from pain-inducing temperature changes.  The proprietary calcium-silicate bioceramic is well tolerated by living mammalian tissues.  The researchers are planning to begin clinical trials in the not-to-distant future.https://medicalxpress.com/news/2025-08-magnetically-nanobots-relief-toot
