Gum is red and hurts
A red, painful gum may reflect plaque-related gingivitis, food trapped at the gumline, trauma, a tooth problem, or a localized infection.
Why might a red gum also become painful?
A red, painful gum may reflect plaque-related gingivitis, food trapped at the gumline, trauma, a tooth problem, or a localized infection.
How does gum inflammation change the tissue?
Healthy gingiva fits closely around the teeth, while inflammation can make it red, tender, swollen, or prone to bleeding. When one area hurts, the source may be the gum pocket, the tooth root, a trapped irritant, or an erupting tooth.
What should you note while caring for sore gums?
Clean gently with a soft toothbrush and between teeth, then note swelling, bleeding, bad taste, sensitivity, and how long the problem has lasted. Do not stop all cleaning because plaque can keep the inflammation active.
When do painful red gums need urgent care?
Arrange prompt care for pus, facial swelling, fever, a loose tooth, severe pain, or difficulty swallowing or breathing. A painful red area that does not settle needs a dental examination.
Is the problem limited to the gum or tooth?
Is the problem limited to the gum or is the tooth also sensitive? Is there a pocket, cavity, trapped food, trauma, or erupting tooth? What treatment is needed?
