What is the typical probing depth range for a healthy sulcus?

Explanation:
Probing depth reflects how deep the sulcus is from the gingival margin to its base. In a healthy sulcus, the gingival margin sits near the tooth surface and the sulcus remains shallow, typically measuring between 1 and 3 millimeters. Depths greater than about 3 millimeters suggest a periodontal pocket from attachment loss and potential disease, though individual anatomy, inflammation, and technique can slightly affect exact measurements. So, the usual healthy sulcus depth range is 1–3 mm.
