What is the expected probing depth range in a healthy individual?

In a healthy individual, the expected probing depth range is typically around 2-3 mm. This range reflects the normal gingival attachment to the tooth and indicates that there is no significant periodontal disease or inflammation present. Probing depths of 2-3 mm suggest healthy periodontal tissues with adequate support for the teeth.

When probing, clinicians assess the distance from the gingival margin to the bottom of the periodontal pocket. Depths greater than this range could indicate potential periodontal issues, such as inflammation or attachment loss, while depths significantly less than this may not accurately capture the healthy attachment levels typically seen in gingival sulcus without periodontal disease. Thus, a probing depth of 2-3 mm is widely accepted in clinical practice as indicative of periodontal health.
