Pain Gate Theory (or Gate Control Theory) is a foundational concept in neuroscience that explains how the spinal cord acts as a "gatekeeper" for pain signals before they reach the brain. Proposed by Ronald Melzack and Patrick Wall in 1965, the theory suggests that non-painful input can "close the gate" to painful input, preventing pain sensations from traveling to the central nervous system.

Commercial dental vibrotactile devices (like DentalVibe or Buzzy) work by bombarding the area with A-beta input. The gate cannot process both the vibration and the sharp pain simultaneously—it prioritizes the vibration. pain gate ddsc 018
