What probe depth is considered healthy in dental examinations?

In dental examinations, a probe depth of less than 3mm is generally considered healthy. This measurement indicates that the gum tissue is attached firmly to the tooth, showing no signs of periodontal disease or significant gum recession. Healthy probing depths typically range from 1mm to 3mm, with depths under 3mm suggesting that periodontal health is maintained.

This probing depth is measured using a periodontal probe, which helps assess the attachment between the gums and the teeth. Probing depths that exceed this range can indicate inflammation or periodontal issues, leading to bone loss and other complications. Hence, a reading of less than 3mm reflects a healthy periodontium, where the gums are well adapted to the teeth, lacking the pocket formation associated with disease.
