Measured with an electronic force sensing probe (Yeaple Probe): 10, 20, 30, 40, up to 50 grams of force are applied to hypersensitive tooth until pain elicited. Grams of force needed to elicit pain are recorded as hypersensitivity score for the tooth. For Tactile Hypersensitivity: The higher the score (the more grams of force needed to elicit a response of pain), the lower the hypersensitivity. Hypersensitivity scores on a per study subject basis are recorded as mean scores of two hypersensitive teeth
