With the progression of periodontal destruction, the following syptoms may occur: moderate to severe gingival inflammation, increased tooth mobility, pathological migration, vertical occlusal dimension loss, improper crown to root ratio, furcation involvement, absence of keratinized gingiva, unaesthetic appearance, as well as difficulties in chewing causing by unstable occlusion.
