A periodontal pocket is a space that forms when the gum detaches from the tooth. Normally the gum fits tightly against the tooth. In the case of inflammation or periodontitis, the gum can pull away. The space that forms is called a periodontal pocket. Bacteria and plaque can accumulate in these pockets. Deep pockets are difficult to keep clean and make the inflammation worse. Using a periodontal probe, the clinician measures the depth in millimetres. A depth of more than 3 mm may indicate periodontitis. With treatment, pockets can become shallower again. Regular measurement is important for monitoring recovery or deterioration.
