Dental question about taxonomy:symptom:gum-pain
Gum pain may come from inflammation, trauma, recession, an ulcer, or infection in the gum or a nearby tooth.
The short answer
Gum pain may come from plaque-related inflammation, an injury, recession, an ulcer, gum disease, or infection in a nearby tooth. A dentist identifies the cause by examining the gum surface, tooth margins, pockets, and bite.
Why can inflamed gums feel tender or sensitive?
Gum tissue contains blood vessels and sensory nerves, so inflammation can make it tender, swollen, or sensitive to brushing. Receding tissue exposes root dentin, while a mouth ulcer affects the surface lining rather than the tooth itself.
What can relieve gum pain while you arrange care?
Use a soft toothbrush, clean plaque gently, and avoid sharp, spicy, or very hot foods over a sore area. Do not place aspirin or concentrated chemicals directly on the gum, because they can injure the tissue.
When should lasting gum pain be checked?
See a dentist for pain that lasts, returns, or affects eating and brushing. Get urgent care for spreading swelling, fever, pus, uncontrolled bleeding, or trouble swallowing or breathing.
How can a dentist identify the source of gum pain?
Ask whether the pain is from the gum or tooth, whether gum measurements or imaging are needed, and what cleaning or treatment will remove the cause. Mention bleeding, sensitivity, ulcers, and recent dental work.
Frequently asked questions
Why do my gums hurt when I brush?
Inflamed gums may bleed and feel tender, while recession, a hard brush, or a local injury can also make brushing painful.
Can gum pain come from a cavity?
Yes. Pain from an infected or inflamed tooth can be felt near the surrounding gum, especially when the root tissues are involved.
