What is the direct answer?
Blood in saliva can come from inflamed gingiva, especially after brushing, but persistent or spontaneous bleeding needs examination to confirm the source.
What does this question mean?
Gingivitis is inflammation of the gingiva, commonly caused by plaque at the gum margin. Blood may also come from the tongue, cheek, nose, throat, or a deeper periodontal pocket.
What can you do next?
Brush gently at the gum line and clean between teeth daily. A dentist can check bleeding, plaque, calculus, pocket depth, and other oral sources.
When should you seek dental care?
Seek care if blood appears repeatedly or without brushing, especially with swelling, pus, loose teeth, bruising, or fatigue.
What should you ask the dentist?
Ask what is causing the symptom, which examination or imaging is needed, and which treatment options address that cause.
