Red veiny gums
Visible red lines in the gums can reflect normal blood vessels, irritation, plaque-related inflammation, trauma, or another local condition.
The short answer
Red branching lines are not a diagnosis by themselves. The dentist looks for swelling, bleeding, ulcers, tenderness, plaque, calculus, medication effects, and changes beyond the gum margin.

What is the direct answer?
What does this question mean?
The description concerns appearance rather than one named disease. Healthy gums may show vascular patterns, while inflamed gingiva is often red, puffy, and prone to bleeding.
What can you do next?
Take a photograph for comparison, brush gently, and clean between teeth without forcing a tool into sore tissue. Avoid tobacco and note when the change began and whether it is localized.
When should you seek dental care?
Seek care for a persistent new change, bleeding without brushing, a lump, ulcer, marked pain, or one-sided colour change. Facial swelling or fever needs prompt attention.
What should you ask the dentist?
Ask whether the colour follows normal anatomy or inflammation and whether periodontal probing is needed. Ask if a medication, injury, restoration, or infection could explain it.
