My gums are bleeding while brushing

The gum margin is the collar of soft tissue where each tooth meets the oral mucosa. Plaque is a sticky bacterial film that collects around this margin; its by-products can make the gingiva red, swollen, tender, and more likely to bleed when a toothbrush or interdental cleaner touches it.

Common contributors include plaque that has hardened into tartar, crowded teeth, a new flossing routine, a firm scrubbing technique, ill-fitting dental appliances, smoking, and changes in general health or medication. Bleeding with loose teeth, gum recession, persistent bad taste, or pus can indicate disease beyond simple surface irritation.

Brush twice daily with a soft-bristled toothbrush, using small gentle movements aimed at the gumline rather than pressing hard across the teeth. Clean between the teeth once daily with floss or an appropriately sized interdental brush, and spit out toothpaste after brushing instead of rinsing heavily.

If the bleeding started after changing your cleaning routine, continue gently and check whether the toothbrush is worn or the interdental brush is too large. A dental professional can remove tartar with scaling, measure the gum pockets with a periodontal probe, and show you a technique suited to your teeth and appliances.

Arrange a dental examination if bleeding continues despite careful daily cleaning, returns often, or affects several areas of the mouth. Seek prompt care for spontaneous bleeding, marked swelling, severe pain, pus, a loose adult tooth, facial swelling, fever, or trouble swallowing or breathing.

At the visit, the dentist or hygienist may inspect the gingiva, check plaque and tartar, measure pocket depths, assess tooth movement and recession, and take dental radiographs when bone loss or another dental cause needs evaluation. Treatment may involve professional cleaning, improved home care, and periodontal treatment matched to the findings.

Ask: “Is the bleeding coming from gingivitis, tartar, periodontal disease, brushing trauma, or another cause?” You can also ask which toothbrush and interdental cleaner fit your mouth, whether your gum pockets and bone levels need assessment, and what changes should prompt an earlier review.
