Gingivitis ("inflammation of the gums") (gingiva) around the teeth is a general term for gingival diseases affecting the gingiva (gums). As generally used, the term gingivitis refers to gingival inflammation induced by bacterial biofilms (also called plaque) adherent to tooth surfaces.
The symptoms of gingivitis are as follows:
Bright-red, or purple gums
Swollen gums that emit pus
Severe oral odor
Gums that are tender, or painful to the touch.
Gums that bleed easily, even with gentle brushing, and especially when flossing.
Gums that itch with varying degrees of severity.
