Gingivitisis the earliest form of periodontal disease. The gums become red, swollen and bleed easily when brushing; these are the common symptoms of gingivitis. There is usually little or no discomfort at this stage. The main cause of gingivitis is the accumulation of dental plaque between the gums and the teeth. Several factors can increase the severity and the risk of progression of gum disease such as smoking, diabetes, immune deficiencies, heredity, medication and stress. Gingivitis is reversible with dental treatment (cleaning) and good oral home care. In the absence of treatment, gingivitis can advance to periodontitis.
