An apparatus for measuring dentin hypersensitivity is provided. The apparatus has a dental probe configured to apply force increasingly on a tooth until the applied force corresponds to a threshold force. Further, the apparatus has a load cell that is positioned in the dental probe. The load cell is configured to generate an electrical signal proportional to the applied force. Further, the apparatus has a microcontroller which is in communication with the load cell. The microcontroller is configured to determine an applied force value corresponding to the electrical signal. Furthermore, the apparatus has a display device. The display device is in communication with the microcontroller. The display device is configured to display the applied force value and a threshold force value digitally. The threshold force value is a quantifiable value of the applied force to which a patient responds and is a measure of the dentin hypersensitivity.
