Bleeding gums usually stop on their own within a few minutes, but if they keep bleeding every time you brush or floss, that’s a sign of inflamed gum tissue that needs attention. The most common cause is plaque buildup along the gumline, and in most cases, consistent oral hygiene will resolve the bleeding within a few weeks. Here’s how to handle it both right now and over the long term.
How to Stop Active Bleeding
If your gums are actively bleeding, press a piece of clean gauze or cloth directly against the spot and hold steady pressure for a full 15 minutes. Use a clock rather than guessing. If blood soaks through, layer another piece on top without removing the first one.
If pressure alone isn’t enough, try biting down on a moistened tea bag for 10 to 15 minutes. Tea contains tannins, compounds that help constrict blood vessels and promote clotting. A cold compress on the outside of your cheek can also slow bleeding by reducing blood flow to the area.
Why Your Gums Are Bleeding
The most likely explanation is gingivitis, an early stage of gum disease caused by plaque that hardens along and under the gumline. Red, swollen, bleeding gums are the hallmark signs. Gingivitis generally doesn’t hurt, which is why many people don’t realize they have it until they notice blood in the sink.
Left untreated, gingivitis can progress to periodontitis, where the inflammation begins attacking the soft tissue and bone that hold your teeth in place. Gaps called “periodontal pockets” form between the gums and teeth, sometimes deepening to a centimeter or more. Over time, teeth can loosen. About 42% of U.S. adults over 30 have some form of periodontitis, and that number climbs to nearly 60% in adults 65 and older.
Other common causes of bleeding gums include:
- Blood-thinning medications. Drugs prescribed to prevent blood clots, including warfarin, aspirin, and newer anticoagulants, reduce your blood’s ability to clot. If you take any of these, even routine brushing can trigger bleeding that takes longer to stop.
- Vitamin C deficiency. Vitamin C is essential for producing collagen, the protein that gives your gum tissue its structure. Clinical studies show that even moderate vitamin C depletion can cause gum bleeding regardless of how well you brush and floss.
- Hormonal changes. Pregnancy, puberty, and menstruation can all increase blood flow to the gums and make them more sensitive to plaque.
- Smoking. Smoking raises the risk of periodontitis by 85% compared to non-smokers. It also reduces blood flow to the gums, which can mask early bleeding and delay diagnosis.
Fix Your Brushing and Flossing Technique
The single most effective thing you can do at home is improve your daily cleaning routine. The goal is removing plaque from the gumline before it hardens into tarite (calculus), which only a dentist can remove.
For brushing, hold your toothbrush at an angle so the bristles point toward the gumline. Make short back-and-forth strokes, then sweep the brush away from the gum toward the edge of the tooth. This is called the modified Bass technique, and it’s the method most dentists recommend. Use a soft-bristled brush and avoid scrubbing hard, which can irritate already inflamed tissue.
For flossing, the key is consistency rather than force. If your gums bleed when you floss, that’s actually a reason to keep flossing, not to stop. The bleeding signals inflammation caused by bacteria trapped between your teeth. Commit to flossing daily and the bleeding should stop within a few weeks as the gum tissue heals and tightens back up around the teeth.
Home Remedies That Help
A saltwater rinse is one of the simplest ways to reduce gum inflammation between brushings. Mix one teaspoon of salt into eight ounces of warm water and swish for 30 seconds. If your gums are particularly tender, cut the salt to half a teaspoon for the first couple of days. Salt draws fluid out of swollen tissue and creates an environment that’s harder for bacteria to thrive in.
Getting enough vitamin C also matters. Research shows that vitamin C supplements can reduce spontaneous bleeding and redness in people with gingivitis, chronic periodontitis, and even those with type 2 diabetes. Vitamin C supports collagen production in the gums and helps with wound healing. Good dietary sources include citrus fruits, bell peppers, strawberries, and broccoli.
When You Need Professional Cleaning
If bleeding persists after two to three weeks of consistent brushing and flossing, or if your gums are pulling away from your teeth, you likely need a professional cleaning that goes deeper than what you can do at home.
A standard cleaning removes plaque and tartar above the gumline. But if pockets have formed between your gums and teeth, your dentist may recommend scaling and root planing, often called a “deep cleaning.” During this procedure, your gums are numbed with a local anesthetic. Your dentist or hygienist then uses hand instruments or ultrasonic tools to remove plaque and tartar from below the gumline, then smooths the tooth roots so the gum tissue can reattach more easily. Antibiotics may be applied directly to the area or prescribed afterward to clear any remaining infection.
Recovery is straightforward. Your gums may feel sore and sensitive for a few days, and you’ll typically return for a follow-up to check whether the pockets have begun to shrink. For many people with moderate gum disease, this single procedure is enough to get things back on track when paired with better daily care at home.
What to Do If You Take Blood Thinners
If you’re on anticoagulant or antiplatelet medications, bleeding gums don’t necessarily mean you have gum disease. Your medication is doing exactly what it’s designed to do: preventing clots. That said, you still need to maintain good oral hygiene, because gum disease on top of blood thinners makes bleeding significantly harder to control.
Let your dentist know every medication you take, including over-the-counter aspirin. Never stop or adjust a blood thinner on your own to reduce gum bleeding. Your dentist and prescribing doctor can coordinate to manage your care safely, especially before procedures like extractions or deep cleanings.
