Dental Erosion is When: The enamel (the hard, protective coating of the tooth) is worn away by exposure to acid, when that happens it leaves the sensitive dentine area of the tooth exposed. Dental erosion of the enamel can result in pain, particularly when consuming hot or cold food.

The enamel on the tooth becomes softer and loses mineral content when we eat or drink anything acidic. However, this acidity is cancelled out by saliva, which slowly restores the natural balance within the mouth. But if the mouth is not given enough time to repair itself (because these acid attacks are happening too often) the surface of the teeth is worn away.
