What Are the Symptoms of Gingivitis?

Gingivitis symptoms include changes in gum color, gum swelling and thickening, gum bleeding, softening of gum texture, and oral malodor. If spontaneous, heavy gum bleeding occurs—especially when accompanied by facial swelling or fever—prompt medical evaluation and treatment are recommended.

1. Change in gum color: Healthy gums are typically light pink; with inflammation, they turn dark red or bright red. These color changes most commonly appear along the gingival margin and interdental papillae. As dental plaque accumulates, the inflamed area gradually expands, creating a clear demarcation from healthy gum tissue.

2. Gum swelling and thickening: The gingival margin becomes rounded and bulging, while the interdental papillae appear enlarged and blunt. The normally snugly fitting gingiva detaches from the tooth surface, and swollen tissue fills the interdental spaces, giving the gums a full, puffy appearance and loss of firmness.

3. Gum bleeding: Bleeding commonly occurs during toothbrushing or chewing hard foods, with varying degrees of severity. Most episodes stop spontaneously; however, some may involve persistent oozing without significant pain—easily overlooked, yet an important early sign of inflammation.

4. Softening of gum texture: Inflamed gum tissue loses elasticity; indentation upon gentle pressure recovers slowly. The normally firm, resilient texture is replaced by a softer, more fragile consistency due to inflammatory hyperemia and edema—making the gums more susceptible to trauma and exacerbating bleeding.

5. Oral malodor: Dental plaque and food debris accumulate in the gingival sulcus, fostering bacterial proliferation and metabolic activity. This produces volatile, foul-smelling metabolites that resist routine rinsing. As inflammation worsens, oral odor becomes increasingly noticeable.

Maintain consistent twice-daily brushing and daily flossing to remove interdental debris. Limit intake of sugary and sticky foods, undergo regular dental check-ups, and receive professional scaling to remove dental calculus—thereby preventing persistent inflammation from progressing to periodontal disease.
