Under both these layer, one more layer is there known as ‘Dentin’, having small hollow tubes known as Microscopic Tubules. When both these layer Enamel and Cementum looses its effectiveness, or to say the protectiveness of these layers degrades, the layer Dentin get in contact with cold, hot, sticky and acidic food and then through small hollow porous tube of Dentin, these food passes on the nerves and cells inside the tooth, which triggers the pain or get responsible for teeth sensitivity.
