Gingivitis is an infectious disease caused by microorganisms in the plaque that accumulates in the neck of the teeth and in the gingival sulcus, generally causing bleeding, hyperplasia or recession of the gums, and a change in the color of the gums with bright red or dark red free gums and gingival papillae.
In addition to the condition of ulceration, bleeding and swelling, gum cancer may have long-term ulcers that do not heal, floating teeth and painful conditions, tissue biopsy and cytological pathology to confirm the diagnosis.
