Gums bleeding for no reason
Bleeding gums usually reflect inflammation from plaque, but persistent or spontaneous bleeding needs a dental examination.
The short answer
Gums that bleed without an obvious injury are often inflamed by plaque and tartar, although gum disease, medication effects, or a less common medical problem can also contribute. Bleeding is a sign to investigate, not a reason to stop gentle cleaning.
How can plaque make healthy-looking gums bleed?
Plaque is a sticky bacterial film that irritates the gingiva, the gum tissue around each tooth. If it hardens into calculus, brushing cannot remove it, and inflammation may cause redness, swelling, tenderness, bad breath, or bleeding; bleeding from several areas can indicate gingivitis or periodontitis.
What should you do when your gums bleed unexpectedly?
Brush twice daily with a soft-bristled brush and fluoride toothpaste, using small movements along the gumline, and clean between the teeth with floss or interdental brushes. Arrange a dental cleaning if calculus is present, and do not start or stop a medicine or supplement without the prescriber’s advice.
When should unexplained gum bleeding be examined?
Book an examination if bleeding continues, happens repeatedly, or comes with loose teeth, gum recession, pus, persistent swelling, or a change in your bite. Seek urgent medical care for heavy bleeding that will not stop with firm gauze pressure, facial swelling affecting breathing or swallowing, or signs of severe illness.
What tests could identify the cause of gum bleeding?
Ask whether the bleeding is caused by gingivitis, periodontitis, calculus, trauma, or another condition, and whether gum measurements or dental radiographs are needed. Ask which interdental tool fits your spaces and when a follow-up periodontal check should occur.
Frequently asked questions
Should I stop brushing bleeding gums?
No. Use gentle technique with a soft brush and have persistent bleeding assessed.
Can tartar cause gum bleeding?
Yes. Calculus can maintain inflammation and needs professional removal.
