The gingival pocket

The gingival pocket (pseudo pocket) are spaces formed between the tooth and the gum, causing the swelling of the gum (gum disease). The formation of these pockets is due in particular to the accumulation of biofilm (dental plaque) at the level of the gingival edge, and under the gum. The gingival pockets are not conducive to any osseous loss.

The periodontal pocket

The periodontal pocket are located more deeply than the gingival ones, i.e. at the level of the bone. They are caused by the destruction of the support tissues of the tooth, including the bone.

Measured with a dental probe, a healthy sulcus proves to be superficial. When a pocket develops because of a disease, the probe reveals an increased depth of sulcus.
