My gums ache
Aching gums can result from plaque-related inflammation, trauma, an ulcer, or infection, so the pattern and gum appearance guide the examination.
The short answer
Aching gums commonly reflect inflammation from plaque, irritation, trauma, or infection, and the cause is found by examining the gums and teeth. Plaque-induced gingivitis may cause redness, tenderness, and bleeding, while a localized abscess, ulcer, or food injury can affect one spot.

What is the direct answer?
What does this question mean?
The location and pattern matter: soreness along many gum margins differs from pain around one tooth or a single ulcer. The clinician looks for plaque and calculus, bleeding, recession, pockets, swelling, tooth decay, cracks, and signs that the bite or a dental appliance is irritating tissue.
What can you do next?
Brush gently twice daily with a soft toothbrush and clean between the teeth with floss or an interdental brush that fits. Avoid tobacco, very hot foods, and scrubbing sore tissue; a dental cleaning may be needed when hardened calculus is present.
When should you seek dental care?
Book an examination if the ache lasts, recurs, or comes with bleeding, swelling, bad breath, pus, loose teeth, or sensitivity in a particular tooth. Fever, facial swelling, or difficulty swallowing or breathing requires urgent care.
What should you ask the dentist?
Ask whether the soreness is gingivitis, periodontitis, an ulcer, trauma, or a tooth problem. Ask what cleaning or treatment is needed, how to clean the affected area, and which symptoms mean you should return sooner.
Frequently asked questions
Why do my gums hurt when I brush?
Tender, inflamed tissue can bleed or ache when brushed, often because plaque remains at the gum margin.
Can an aching gum be caused by one tooth?
Yes. Decay, a cracked tooth, or infection near one root can make the nearby gum sore or swollen.
