What type of movement is associated with Class 0 mobility?

Class 0 mobility indicates a state where the tooth remains stable and firmly anchored in the alveolar bone, reflecting normal physiological movement. This level of mobility signifies that there is no significant displacement of the tooth during clinical examination, and it remains within the usual limits of movement expected in a healthy tooth. Normal mobility is essential because it allows for slight movement in response to the forces exerted during chewing and other activities, but it should never exceed the normal physiological range.

In contrast, excessive lateral displacement, depression in a vertical direction, and severe mobility denote pathological conditions where there is either significant loosening of the tooth or structural damage. Such conditions can arise from periodontal disease, trauma, or other dental issues, highlighting the importance of recognizing Class 0 mobility as a sign of dental health.
