ABSTRACT:
A tooth mobility measuring apparatus of this invention includes an impact mechanism which injects or sucks a fluid to apply an impact to a tooth, a sensor which detects the displacement state of the tooth which is moved by the impact force from the impact mechanism, and a tooth mobility calculation mechanism which calculates the tooth mobility of the tooth on the basis of the output signal from the sensor. The displacement state of the tooth is measured without touching the tooth.
