My teeth started bleeding for no reason
Bleeding from the gums without an obvious injury usually reflects inflammation from plaque, but persistent or heavy bleeding needs dental assessment.
Why might your teeth bleed without an obvious injury?
Bleeding from the gums without an obvious injury usually reflects inflammation from plaque, but persistent or heavy bleeding needs dental assessment.
What problems can cause bleeding from the gums?
Gum bleeding commonly comes from gingivitis, brushing too hard, trapped food, dental calculus, gum disease, or less often a mouth injury or a medical condition. The blood comes from inflamed gum tissue around the teeth.
How should you clean your teeth when your gums bleed?
Use a soft toothbrush, brush the gumline gently with fluoride toothpaste, and clean between the teeth daily. Do not stop cleaning because light bleeding can persist when plaque remains at the gumline.
When does unexplained gum bleeding need dental care?
Arrange a dental examination if bleeding continues, recurs, or comes with swollen gums, bad breath, loose teeth, pus, or pain. Seek urgent care for heavy bleeding that will not stop or swelling that affects breathing or swallowing.
What tests could identify the reason for gum bleeding?
Ask whether the bleeding is from gingivitis, calculus, periodontal pockets, trauma, or another cause, and whether you need periodontal measurements, radiographs, or a professional cleaning.
