What can you do next?

Guide floss gently between teeth, curve it around each tooth, and clean daily; interdental brushes may suit wider spaces.

When should you seek dental care?

Book care when bleeding continues, gums swell, breath smells persistently, or teeth feel loose.

What should you ask the dentist?

Ask whether this is gingivitis or deeper periodontal disease and which interdental size fits.
