Bleeding gums are almost always a sign of inflammation, and the most common cause is plaque buildup along the gumline. The good news: in most cases, you can stop the bleeding within one to two weeks by improving your daily oral hygiene and making a few simple changes at home. Here’s what to do right now and what to watch for if things don’t improve.
Rinse With Salt Water
A warm saltwater rinse is one of the fastest ways to calm inflamed gums. Mix 1 teaspoon of salt into 8 ounces of warm water until it dissolves, then swish it around your mouth for 15 to 30 seconds and spit it out. You can do this up to four times a day, including after meals. If the rinse stings or feels too strong, cut the salt down to half a teaspoon.
Salt water draws fluid out of swollen tissue and creates an environment that’s harder for bacteria to thrive in. It won’t fix the underlying cause, but it reduces discomfort and helps the tissue start healing while you work on the bigger picture.
Keep Brushing, but Fix Your Technique
It feels counterintuitive to brush gums that are already bleeding, but stopping will only make things worse. Plaque continues to accumulate, and the inflammation deepens. The key is brushing correctly so you remove plaque without traumatizing the tissue further.
Hold your toothbrush at a 45-degree angle to the gumline and use gentle, short strokes about one tooth wide. You’re aiming to sweep plaque away from where the gum meets the tooth, not scrub hard across it. If you’re pressing too hard, that alone can cause bleeding or make existing inflammation worse.
Switch to a soft or ultra-soft bristle toothbrush if you haven’t already. Electric toothbrushes with a built-in pressure sensor can help here. These models reduce their power automatically when you push too hard, which protects tender gums while still cleaning effectively. If your hygienist has told you that you’re missing areas or using poor technique, an electric brush takes some of the guesswork out of the equation.
Floss daily, even if it causes bleeding at first. The bleeding typically decreases within a week or two as the gums become less inflamed. If string floss is painful, try interdental brushes or a water flosser to clean between teeth more comfortably.
Why Your Gums Are Bleeding
The most likely explanation is gingivitis, the earliest stage of gum disease. It shows up as red, swollen gums that bleed when you brush or floss. Gingivitis is caused by bacteria in plaque irritating the gum tissue, and it’s fully reversible with consistent cleaning.
When gingivitis goes untreated, it can progress to periodontitis. At this stage, the gums start pulling away from the teeth and forming deep pockets that trap more bacteria. These pockets can reach several millimeters deep, sometimes more than a centimeter. Along with bleeding, you may notice receding gums, persistent bad breath, sensitive teeth, or teeth that feel slightly loose. Periodontitis causes permanent damage to the bone supporting your teeth, so catching it early matters.
Medications That Increase Bleeding
Blood thinners are the most well-known culprit. Antithrombotic drugs affect your body’s ability to clot, and gums are full of tiny blood vessels that bleed easily when inflamed. If you take a blood thinner and notice your gums bleeding more than expected, mention it to both your dentist and your prescribing doctor. Some other medications have also been linked to increased gum bleeding, including certain blood pressure medications, antidepressants, and anti-inflammatory painkillers. Don’t stop any medication on your own, but it’s worth checking whether gum bleeding is a known side effect of something you’re taking.
Pregnancy and Hormonal Changes
Rising levels of estrogen and progesterone during pregnancy increase blood flow to gum tissue, making it more reactive to plaque. Bleeding on probing tends to climb throughout pregnancy and peaks in the third trimester. The reassuring part: these changes typically resolve on their own within about three months after delivery, even without professional treatment. Keeping up with brushing and flossing during pregnancy is the best way to minimize the problem.
Vitamin C Deficiency
Your gums need vitamin C to maintain the connective tissue that holds them together. When levels drop too low, gum tissue becomes fragile and bleeds more easily. Adult men need about 90 milligrams a day. Harvard Health suggests boosting intake through foods like oranges, kiwis, bell peppers, and kale, or taking a 100 to 200 milligram supplement daily. This won’t replace good oral hygiene, but if your diet has been lacking in fruits and vegetables, low vitamin C could be contributing to the problem.
What a Dentist Can Do
If your gums are still bleeding after two weeks of consistent home care, or if you notice deep pockets forming between your teeth and gums, a professional cleaning goes beyond what brushing and flossing can reach. The standard procedure is scaling and root planing, often called a “deep cleaning.” Your hygienist uses specialized instruments to remove hardened plaque (tarite) from below the gumline and smooth the root surfaces so gums can reattach more easily.
The evidence for this procedure is strong. Multiple clinical trials show that pocket depth decreases significantly within 4 to 28 weeks after treatment, and the percentage of sites that bleed drops consistently compared to no treatment. Many patients see their pockets shift from the moderate or severe range back to 3 millimeters or less, which is considered healthy. You may need more than one session depending on how advanced the disease is, and your dentist will likely schedule follow-up visits to monitor progress.
Signs That Need Urgent Attention
Most gum bleeding is a slow-developing hygiene issue, not an emergency. But certain symptoms alongside bleeding gums point to something more serious, like an abscess or spreading infection. If you develop a fever along with facial swelling and can’t reach your dentist, go to an emergency room. The same applies if you have difficulty breathing or swallowing, which can signal that an infection has spread deeper into the jaw, throat, or neck.
Other signs worth getting checked promptly: pus between your teeth and gums, a sudden bad taste in your mouth, pain that throbs or wakes you up at night, or gums that have pulled away noticeably from one or more teeth. These don’t always mean an emergency, but they do mean your next dental visit shouldn’t wait.
