Theory of tooth movement
WebbThe Hydrodynamic or Fluid Movement theory is one of three main theories in dentistry developed to explain dentine hypersensitivity, which is a sharp, transient pain arising from stimuli exposure. [1] It states that different types of stimuli act on exposed dentine, causing increased fluid flow through the dentinal tubules.
