Red tender gums
Red, tender gums commonly reflect plaque-related gingivitis, but trauma, ulcers, medication effects, and infection can also produce the same appearance.
The short answer
Red, tender gums often reflect gingivitis from plaque at the gum margin, although trauma, ulcers, medicines, and infection can have similar appearances.
Why do inflamed gums look red and feel tender?
Gingiva become red when inflamed blood vessels and immune cells increase in the tissue. Swelling, bleeding during brushing, food trapping, a rough filling, smoking, mouth breathing, and hormonal changes can alter the pattern.
How should you clean red tender gums each day?
Brush gently along the gumline with a soft brush and clean between the teeth daily. Avoid scrubbing the sore area, smoking, and using irritating home mixtures; arrange a professional cleaning if hardened calculus is present.
When should persistent tender gums be examined?
See a dentist if tenderness or redness persists, gums bleed repeatedly, a tooth feels loose, or there is a lump or pus. Rapid swelling, fever, or difficulty swallowing needs urgent attention.
What could be causing the redness and tenderness?
Ask whether plaque, calculus, a filling edge, trauma, medication, or another condition explains the redness, and whether periodontal measurements or cleaning are needed.
Frequently asked questions
Why do sore gums bleed when brushed?
Inflamed gingiva have a fragile surface and can bleed with gentle contact, especially where plaque remains.
Can red gums be caused by a sharp tooth edge?
Yes. Repeated trauma from a tooth, filling, appliance, or food can localize tenderness and redness.
