The distance in millimetres from the gingival margin to the base of the sulcus or pocket, measured with a periodontal probe.
I'll record the probing depths around each tooth so we can monitor your gum health over time.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
