Inflamed gums are almost always caused by bacterial plaque building up along and beneath the gumline, and in most cases, you can reverse the problem at home with consistent oral hygiene changes. About 4 in 10 U.S. adults over 30 have some form of gum disease, so this is one of the most common health issues people deal with. The good news: early-stage gum inflammation (gingivitis) is fully reversible, while advanced disease (periodontitis) is not.
Why Your Gums Are Inflamed
Gum inflammation starts when a sticky film of bacteria, called plaque, accumulates on your teeth and irritates the surrounding tissue. Within days of inconsistent brushing or flossing, your gums respond with redness, swelling, and bleeding. At this stage, the damage is limited to soft tissue. Your gums may bleed when you brush or floss, but the bone and ligaments holding your teeth in place are still intact.
If plaque stays in place long enough, it hardens into tarite (calculus) that you can’t remove at home. The bacteria work their way deeper beneath the gumline, creating pockets between your teeth and gums. Once those pockets reach 4 millimeters or deeper and bone loss begins showing on X-rays, you’ve crossed from gingivitis into periodontitis. That distinction matters because bone loss is permanent. Everything in this article is aimed at stopping inflammation before it reaches that point, or managing it if it already has.
Fix Your Brushing and Flossing Technique
The single most effective thing you can do is clean your teeth more thoroughly. Brush twice a day and floss at least once daily. That’s the baseline recommendation from the American Academy of Periodontology. Most people brush regularly but skip flossing, which leaves the surfaces between teeth coated in plaque, exactly where gum disease tends to start.
When you floss inflamed gums, expect some bleeding for the first week or two. This is normal and not a reason to stop. Curve the floss into a C-shape around each tooth and slide it gently below the gumline rather than snapping it straight down. As the inflammation resolves, the bleeding will taper off.
If you’re using a manual toothbrush, consider switching to an oscillating-rotating electric toothbrush. A meta-analysis comparing toothbrush types found that 72% of people using oscillating-rotating brushes transitioned to healthy gums, compared to just 21% using manual brushes. The electric brushes also reduced bleeding sites by 52% more than manual brushes. Angle the brush head at 45 degrees toward your gumline and let the bristles do the work. Pressing too hard can irritate tissue further.
Salt Water Rinses
A warm salt water rinse is a simple, low-cost way to reduce gum swelling between brushings. Mix one teaspoon of salt into eight ounces of warm water and swish for 30 seconds. If your gums are very tender and the rinse stings, cut the salt to half a teaspoon for the first couple of days. You can rinse after meals to help keep your mouth clean, but avoid doing it excessively throughout the day, since swallowing too much salt water can dehydrate you.
Salt water won’t cure gum disease on its own, but it creates a temporarily alkaline environment that makes it harder for bacteria to thrive. Think of it as a helpful addition to brushing and flossing, not a replacement.
Check Your Vitamin C Intake
Low vitamin C levels in the bloodstream are directly associated with increased gum bleeding, even with gentle probing. If your diet is low in fruits and vegetables, a mild deficiency could be making your gum inflammation worse. The recommended daily intake for adult men is 90 mg and 75 mg for women.
Harvard Health suggests boosting your intake through foods like kale, bell peppers, oranges, and kiwis, or taking a daily supplement of 100 to 200 mg. This won’t replace proper oral hygiene, but if your body doesn’t have enough vitamin C to maintain healthy connective tissue in your gums, no amount of brushing will fully resolve the problem.
Prescription Mouthwash
If home care alone isn’t bringing your inflammation under control, your dentist may prescribe a chlorhexidine mouthwash. This is used as a 15-milliliter rinse, swished for 30 seconds, twice a day. It’s effective at reducing gum redness, swelling, and bleeding.
The tradeoff: chlorhexidine can stain your teeth, fillings, and dental appliances brown. The staining on natural teeth can usually be polished off at a cleaning, but stained tooth-colored fillings (especially on front teeth with rough surfaces) may need to be replaced entirely. It also increases tartar buildup. For these reasons, it’s typically used as a short-term treatment rather than a permanent part of your routine.
Professional Cleaning and Scaling
Once plaque hardens into tartar, no toothbrush or rinse can remove it. You need a professional cleaning. For gingivitis, a standard cleaning is usually enough. Your hygienist scrapes tartar off the tooth surfaces above and below the gumline, which immediately removes a major source of bacterial irritation.
If your gum pockets have deepened or bone loss has started, you may need a deeper procedure called scaling and root planing. This involves cleaning beneath the gumline and smoothing the root surfaces so gums can reattach more tightly to the teeth. It’s typically done with local numbing and may take two visits. After treatment, most people notice reduced swelling and bleeding within a few weeks, though you’ll need regular follow-up appointments to keep things stable.
Signs That Need Prompt Attention
Mild redness and occasional bleeding when flossing can usually be managed at home. But certain symptoms signal that inflammation has progressed beyond what home care can fix:
- Persistent bad breath or an unpleasant taste that doesn’t go away with brushing
- Pus along the gumline, which indicates active infection
- Gum recession, where your gums are visibly pulling away from your teeth
- Loose teeth or a change in your bite
- Pain when chewing
- Reddish or purplish gums that are tender to the touch
Any of these warrants a dental visit. Periodontitis affects about 60% of adults over 65, so age alone increases your risk. If it’s been more than six months since your last cleaning, or if your gums bleed every time you brush, getting a professional evaluation gives you a clear picture of where things stand and whether you need treatment beyond what you can do at home.
