Bottom gums are dark red
Dark-red lower gums may reflect inflammation, irritation, trauma, or normal pigmentation, depending on the pattern and symptoms.
The short answer
Dark-red lower gums may reflect inflammation, irritation, trauma, or normal pigmentation, depending on the pattern and symptoms. The lower gums are gingiva around the front and back teeth. Dark-red colour can indicate increased blood flow and inflammation, but normal pigmentation, recent brushing trauma, heat, or a local irritant can also change appearance.
How can gum inflammation make the lower gums look red?
Plaque-induced gingivitis commonly causes red, puffy, tender gums that bleed with brushing. A single red area may instead reflect a sharp tooth edge, food trauma, a burn, a canker sore, or infection.
How should you clean dark-red lower gums gently?
Use a soft brush with gentle gumline strokes and clean between the teeth. Avoid tobacco, harsh mouthwash, and picking at the area, and photograph the change so you can notice whether it spreads.
When should persistent dark-red gums be examined?
Arrange an examination for bleeding, pain, pus, ulceration, swelling, a lump, or a colour change that persists. Urgent care is needed for rapidly spreading swelling or difficulty swallowing or breathing.
Is the dark-red colour normal pigmentation or inflammation?
Ask whether the colour is normal pigmentation or inflammation and whether plaque, calculus, trauma, or a medication contributes. Ask whether the area needs periodontal measurements or other tests.
