Inflamed gums are almost always caused by plaque buildup along the gumline, and the good news is that early-stage gum inflammation (gingivitis) is fully reversible with the right care. Treatment combines better daily cleaning habits with targeted rinses and, when needed, a professional deep cleaning. Most people see noticeable improvement within one to two weeks of consistent effort.
Why Gums Become Inflamed
Plaque is a sticky, colorless film of bacteria that forms on your teeth every time you eat, especially after sugary or starchy foods. When plaque isn’t removed daily, it hardens under the gumline into tartar (also called calculus), which traps even more bacteria against your gum tissue. Your immune system responds to those bacteria with inflammation: redness, swelling, tenderness, and bleeding when you brush or floss.
Certain conditions make this process worse. High blood sugar, for example, impairs your body’s ability to fight oral infections and increases glucose in your saliva, giving harmful bacteria extra fuel to multiply. Hormonal changes during pregnancy, smoking, dry mouth from medications, and a weakened immune system all raise your risk as well.
How to Brush for Inflamed Gums
The single most effective thing you can do at home is improve your brushing technique. The method dentists recommend most often is the Modified Bass technique: hold a soft-bristled toothbrush at a 45-degree angle to your gumline, make short back-and-forth strokes, then sweep the brush away from the gumline toward the edge of each tooth. This angle lets the bristles clean just under the gum margin where plaque collects, without scrubbing hard enough to damage tissue.
Brush for a full two minutes, twice a day, and replace your toothbrush every three months or when the bristles fray. A toothpaste containing stannous fluoride offers an added advantage over standard sodium fluoride: it kills bacteria by disrupting their metabolic processes. In a two-year clinical trial, stannous fluoride reversed gum recession by about three-quarters of a millimeter during the second year, performing as well as antibiotic-containing toothpaste.
Flossing once a day is non-negotiable. Plaque between teeth is invisible and unreachable by any toothbrush. If traditional floss feels awkward, interdental brushes or a water flosser accomplish the same goal.
Rinses That Reduce Inflammation
A simple saltwater rinse can help calm swollen gums. Mix half a teaspoon of salt into a cup of warm water and swish for 30 seconds. Salt draws fluid out of inflamed tissue, temporarily reducing swelling and creating an environment less hospitable to bacteria. You can do this two to three times a day, especially after meals.
For more persistent inflammation, a prescription chlorhexidine mouthwash is the strongest antimicrobial rinse available. The standard dose is 15 milliliters swished for 30 seconds, twice daily. It’s highly effective at killing oral bacteria, but it comes with trade-offs: it can stain teeth and dental fillings brown and accelerate tartar buildup. Using a tartar-control toothpaste and flossing daily helps counteract this. Chlorhexidine is typically prescribed for a limited course, not long-term use.
Tea tree oil has also shown promise. A systematic review found that tea tree oil was actually superior to chlorhexidine at reducing signs of gingival inflammation, though chlorhexidine was better at preventing plaque from forming in the first place. If you want to try it, look for a toothpaste or mouthwash that contains tea tree oil rather than applying the essential oil directly, and never swallow it.
When You Need a Professional Cleaning
If your gums have been inflamed for more than two weeks despite improved home care, or if you can see hard yellowish deposits along your gumline, you likely have tartar that only a dental professional can remove. A standard cleaning handles tartar above the gumline. When tartar and bacteria have migrated below the gumline, your dentist will recommend scaling and root planing, sometimes called a deep cleaning.
During this procedure, your gums are numbed with a local anesthetic. Your dentist or hygienist uses hand instruments or ultrasonic tools to scrape away plaque and tartar from beneath the gumline, then smooths the root surfaces so gum tissue can reattach more easily. Antibiotics may be placed directly around the tooth roots or prescribed orally afterward to clear any remaining infection. On average, gums take about five to seven days to heal after a deep cleaning, though full tissue reattachment continues over several weeks.
Signs Your Inflammation Has Progressed
Gingivitis is the mild, reversible stage. If left untreated, it progresses to periodontitis, which damages the bone and connective tissue holding your teeth in place. The key differences are easy to spot:
- Gingivitis: red, puffy gums that bleed when you brush or floss, but teeth feel stable and gums sit snugly around each tooth.
- Periodontitis: gums visibly pulling away from teeth, persistent bad breath that doesn’t improve with brushing, loose or shifting teeth, pain when chewing, and increased sensitivity.
As gums break down in periodontitis, they pull away from the teeth and create deep pockets. Bacteria colonize these pockets, causing further tissue and bone loss. Once bone is lost, it doesn’t grow back on its own, which is why catching inflammation early matters so much. If your teeth feel loose, have shifted position, or your gums are receding noticeably, that warrants prompt dental evaluation.
What a Realistic Timeline Looks Like
With consistent brushing, flossing, and rinsing, mild gingivitis typically starts improving within a few days. Bleeding during brushing often decreases within the first week, and gum color shifts from deep red back toward a healthy pink over one to two weeks. If you’ve had a deep cleaning, expect some soreness and sensitivity for five to seven days, followed by steady improvement.
If you’re not seeing any change after two to three weeks of diligent home care, that’s a strong signal that tartar below the gumline is sustaining the inflammation and professional treatment is needed. People with diabetes or other conditions that impair immune function may find that gum inflammation returns more quickly, making regular dental cleanings (every three to six months rather than once a year) an important part of long-term management.
