Tooth mobility is primarily assessed through periodontal probing during a periodontal examination. This procedure involves applying gentle pressure to the tooth in different directions to determine how much movement is present within the socket. The degree of mobility can indicate the health of the supporting tissues around the tooth, as well as the presence of periodontal diseases.

Oral inspection mainly focuses on the visual examination of the gums, teeth, and overall oral cavity but does not provide a direct assessment of tooth mobility. X-ray imaging can help identify underlying bone loss or other issues affecting the supporting structures of teeth but does not measure mobility directly. The patient interview gathers information about the individual's dental health history and symptoms, but it does not evaluate the physical condition of tooth mobility. Thus, periodontal probing is the specific technique that directly evaluates how much a tooth can move, making it the correct choice for assessing tooth mobility.
