Dentinal hypersensitivity is a common dental condition characterized by short, sharp pain arising from exposed dentin in response to external stimuli. These stimuli may be thermal, tactile, osmotic, evaporative, or chemical in nature, such as cold air, hot or sweet foods, tooth brushing, or acidic drinks. The condition occurs when protective enamel or cementum is lost due to erosion, abrasion, attrition, gingival recession, or periodontal therapy, leaving dentinal tubules open. According to the hydrodynamic theory, fluid movement within these tubules stimulates nerve endings in the pulp, producing pain. Dentinal hypersensitivity does not involve spontaneous pain and resolves when the stimulus is removed. Management focuses on reducing tubule patency and nerve excitability through desensitizing agents, fluoride therapy, behavioral modification, and appropriate restorative or periodontal care approaches. dental clinic in Nolambur, dentist in Nolambur, best dental clinic in Nolambur, best dentist in Nolambur, root canal treatment in Nolambur, dental crowns and bridges in Nolambur, wisdom tooth removal in Nolambur, dental brackets and wires in Nolambur, denture treatment in Nolambur, near me, dental clinic in Mogappair, dentist in Mogappair, best dental clinic in Mogappair, best dentist in Mogappair, root canal treatment in Mogappair, dental crowns and bridges in Mogappair, wisdom tooth removal in Mogappair, dental brackets and wires in Mogappair, denture treatment in Mogappair, near me .
