The short answer
Redness along the lower gums usually indicates inflammation of the gingiva, often from plaque or calculus, but it can also follow trauma, food impaction, a dental appliance, allergy, or infection. The cause depends on the exact site and accompanying symptoms.

What is the direct answer?
What does this question mean?
Look for swelling, bleeding, tenderness, ulcers, pus, bad breath, recession, or a tooth that hurts when biting. Redness confined to one spot differs from generalized gum inflammation and should be examined accordingly.
What can you do next?
Brush twice daily with a soft brush, clean between teeth, and avoid tobacco and aggressive scrubbing. Do not place aspirin or caustic products on the gums, and arrange a cleaning or examination if redness persists.
When should you seek dental care?
The dentist or hygienist checks plaque and calculus, probes the gum margins, examines restorations and appliances, and tests nearby teeth when a tooth problem could be contributing. Treatment may include professional debridement or dental treatment for the source.
What should you ask the dentist?
Seek prompt care for pus, a spreading swelling, fever, severe pain, loose teeth, or an ulcer that does not heal. Bleeding that is heavy or difficult to control also needs assessment.
