Inflamed gums are almost always reversible, and in many cases, you can see improvement within days of changing your daily routine. The most common cause is gingivitis, an early stage of gum disease triggered by plaque buildup along and below the gumline. The good news: unlike more advanced gum disease, gingivitis doesn’t cause permanent damage, so acting now makes a real difference.
Why Your Gums Are Inflamed
Plaque, a sticky film of bacteria, constantly forms on your teeth. When it isn’t removed thoroughly, it hardens into tartar within about 24 to 72 hours. Both plaque and tartar irritate gum tissue, causing the redness, swelling, and bleeding you’re noticing. Other factors can make things worse: smoking restricts blood flow to the gums, hormonal changes during pregnancy or menstruation increase sensitivity, and certain medications that cause dry mouth reduce your natural defense against bacteria.
Low vitamin C intake is another overlooked contributor. Research from Harvard Health Publishing found that low vitamin C levels in the bloodstream were associated with an increased risk of gum bleeding, even with gentle probing. The recommended daily intake is 90 mg for adult men (75 mg for women), but aiming for 100 to 200 mg through foods like bell peppers, kiwis, oranges, and kale can support gum repair.
Fix Your Brushing and Flossing Routine
This is the single most effective thing you can do at home. Brush twice a day for two full minutes, angling the bristles at 45 degrees toward the gumline so they sweep under the edge where plaque hides. Use a soft-bristled brush. Medium or hard bristles can further irritate already swollen tissue.
If you’ve been considering an electric toothbrush, the data strongly favors making the switch. A large Cochrane Review found that electric toothbrushes achieved about 21% greater plaque reduction and 11% greater gingivitis reduction compared to manual brushing over periods longer than three months. Oscillating-rotating models performed especially well: one clinical trial found they reduced bleeding sites by more than double compared to manual brushes. You don’t need an expensive model. A basic oscillating-rotating brush will do the job.
Floss once daily. If traditional floss is difficult or uncomfortable, interdental brushes or a water flosser work just as well for clearing bacteria between teeth. The key is consistency. Plaque reforms constantly, so skipping even a day lets it start hardening again.
Home Rinses That Help
A warm saltwater rinse is a simple, effective way to reduce gum inflammation between brushings. Dissolve half a teaspoon of salt in a cup of warm water and swish gently for 30 seconds. The salt draws fluid out of swollen tissue and creates an environment that’s less hospitable to bacteria. You can do this two to three times a day, especially after meals.
Over-the-counter antiseptic mouthwashes containing cetylpyridinium chloride or essential oils (like those in Listerine) can also reduce plaque and bacterial counts. Use them as a supplement to brushing and flossing, not a replacement. Swish for the time listed on the label, and avoid eating or drinking for 30 minutes afterward so the active ingredients can work.
When You Need Professional Treatment
If your gums are still swollen, tender, or bleeding after two weeks of diligent home care, the inflammation likely involves tartar buildup below the gumline that you can’t reach with a toothbrush. A professional cleaning removes this buildup and gives your gums a fresh starting point.
For mild gingivitis, a standard cleaning is often enough. If your dentist finds deeper pockets between your gums and teeth (a sign that inflammation has progressed), they may recommend scaling and root planing, sometimes called a deep cleaning. During this procedure, your gums are numbed with local anesthesia, and a hygienist uses hand instruments or ultrasonic tools to remove plaque and tartar both above and below the gumline. They then smooth the tooth roots so gums can reattach more easily. The whole process takes one to two hours, sometimes split across two visits. Your dentist may also place antibiotics around the roots or prescribe a short oral course to help control bacteria afterward.
In some cases, your dentist may prescribe a medicated mouth rinse. The prescription-strength version used for gingivitis is swished for 30 seconds, twice daily. It’s effective at killing bacteria but can stain teeth and increase tartar buildup with prolonged use, so it’s typically used for a limited period. Brushing with a tartar-control toothpaste and keeping up with flossing helps minimize staining while you’re using it.
How Long Recovery Takes
The timeline depends on how far the inflammation has progressed. According to the Mayo Clinic, if you follow your dentist’s recommendations and maintain consistent brushing and flossing, healthy gum tissue should return within days or weeks. Most people notice less bleeding within the first week of improved home care. Swelling and redness take a bit longer but generally resolve within two to three weeks.
After a deep cleaning, your gums may feel sore and sensitive for a few days. Some bleeding during brushing is normal in the first week. Full healing of the gum pockets typically takes several weeks, and your dentist will usually schedule a follow-up visit four to six weeks later to measure whether the pockets have shrunk.
Preventing It From Coming Back
Gum inflammation recurs easily if daily habits slip. Beyond brushing and flossing, a few things make a measurable difference. Get a professional cleaning every six months (or more frequently if your dentist recommends it) to catch tartar before it triggers new inflammation. Replace your toothbrush or brush head every three months, since frayed bristles lose their cleaning effectiveness. If you smoke, reducing or quitting will improve blood flow to gum tissue, which directly speeds healing and lowers your risk of recurrence.
Pay attention to your diet. Beyond vitamin C, crunchy fruits and vegetables like apples and carrots help mechanically clean teeth, while sugary and starchy foods feed the bacteria that produce plaque. Staying hydrated also matters: saliva is your mouth’s natural rinse cycle, and dehydration reduces its flow.
