The REAL Hidden Cause of Tooth Sensitivity – Sympathetic Dental Hypersensitivity – PDP240

How on earth can a neck injection eliminate teeth sensitivity?Can a patient’s tooth sensitivity really be linked to their occlusion?Is occlusal adjustment ever indicated for sensitivity?And what’s the actual mechanism behind those cases where everything looks fine — no cracks, no significant wear, no exposed dentine — yet the patient still complains their teeth are sensitive?In this episode, Dr. Nick Yiannios shares the concept of Sympathetic Dental Hypersensitivity (SDH), a groundbreaking way of understanding sensitivity that goes beyond the usual suspects like caries, erosion, or leakage.We dive into how the sympathetic nervous system in the pulp can drive unexplained pain, why traditional approaches often fail, and how objective tools like T-Scan and EMG can reveal what articulating paper misses.This could completely change the way you diagnose and manage those “mystery” sensitivity cases that just don’t add up. https://youtu.be/a2Mg72Y_zkw Watch PDP240 on YoutubeProtrusive Dental Pearl: When fitting a resin-bonded bridge (RBB), if you’re unsure about the fit and cement gap, use light-bodied PVS on the intaglio surface of the wing. After setting and peeling it away, the thickness of the PVS shows you the expected cement layer. Ideally, it should be thin and even; a thicker area highlights where your gap is excessive.Need to Read it?

Identify diagnostic tools (e.g., T-Scan, JVA, imaging) that provide objective data for managing sensitivity.3. Evaluate treatment options, including laser-ozone therapy, occlusal adjustments, and neck block techniques.
