What can swollen gums and bad breath indicate?

Swollen gums with persistent bad breath often indicate plaque-related gum inflammation, although a dental or non-dental source can also be involved.

Why can gum inflammation cause swelling and odour?

Bacteria in plaque and gum pockets can produce volatile sulfur compounds, while inflammation makes gingiva red, tender, and prone to bleeding. Food traps, decay, a coated tongue, dry mouth, smoking, and throat conditions may contribute.

How can you care for swollen gums and bad breath?

Brush the gumline and tongue gently, clean between teeth daily, drink water, and avoid masking odor with mouthwash alone. Arrange professional cleaning when calculus or deep pockets prevent home care from reaching the source.

When do swollen gums and odour need care?

Book dental care when swelling or odor persists, or when there is bleeding, pus, pain, loose teeth, recession, or a bad taste. Rapid facial swelling, fever, or trouble swallowing or breathing needs urgent help.

Where might the odour be coming from?

Ask whether the odor starts in the gums, teeth, tongue, or another area, whether periodontal measurements are needed, and which treatment removes the source.

What else can cause it?
