Attached Gingiva
When attached gingiva is the terminal age or border for the gingiva surrounding the teeth in a collar-like fashion. Form a soft tissue wall of the gingiva sulcus and usually, this will be one millimeter wide.
The width of the attached gingiva is an important clinical parameter. This is the distance between the mucogingival junction and the projection of the external surface of the bottom of the gingival sulcus or the periodontal pocket. While the range of variation is between one and nine millimeters.
So with age, the thickness of this attached gingiva will increase, so usually when you are between 20 and 30 years will be a little bit lower than when you are from 40 to 50 years.
That attached gingiva that we were saying, protects the periodontal from injury caused by frictional forces encountered during mastication and dissipates the pole on the gingival margin created by the muscle of adjacent alveolar mucosa.
