Close-up of the teeth & gums of a person suffering from widespread gingivitis (gum disease), showing the swollen & inflamed appearance of the gums, which may bleed easily. Chronic gingivitis is an early stage of periodontal disease (a disease affecting structures which support the teeth) & is caused by accumulation of plaque (formed by bacterial action on food residue) in the spaces (gingival crevices) between the gums amp;& teeth. The spaces become enlarged & the disease may progress to the underlying structures (the periodontal membrane & alveolar bone), eventually leading to possible loosening & loss of teeth.
