Swollen gums are almost always a sign of inflammation, and the fastest way to bring that swelling down is to remove the bacteria causing it. For most people, that means improving how you brush and floss, rinsing with salt water, and applying a cold compress for short-term relief. If the swelling doesn’t improve within a week or two of consistent care, a dental visit is the next step.
Why Your Gums Are Swollen
The most common cause is plaque buildup along and just beneath the gumline. When bacteria in plaque irritate your gum tissue, your body responds with inflammation: redness, puffiness, and bleeding when you brush. This early stage is gingivitis, and it’s reversible. Your gums haven’t lost any attachment to your teeth yet, so the damage can be undone entirely with better daily care.
If plaque hardens into tartar and stays in place for months, the infection can deepen. Pockets form between your teeth and gums, bone starts to break down, and the condition progresses to periodontitis. At that point, home care alone won’t fix it. The key difference: gingivitis involves surface inflammation with no bone loss, while periodontitis means the supporting structures of your teeth are actively deteriorating.
Less obvious causes include hormonal changes (pregnancy, puberty, menstruation), vitamin deficiencies (especially vitamin C), and certain medications. About half of people taking phenytoin, a common seizure medication, develop some degree of gum overgrowth. Blood pressure medications called calcium channel blockers can do the same, with nifedipine causing gum changes in roughly 38% of users and diltiazem in about 20%. If your gums started swelling after beginning a new medication, that connection is worth raising with your doctor.
Upgrade Your Brushing Technique
Brushing twice a day for two full minutes is the baseline recommendation for reducing gum inflammation. But technique matters as much as frequency. Most people brush across their teeth in a scrubbing motion, which misses the area where gums meet teeth, exactly where plaque does the most damage.
The most effective approach for inflamed gums is called the Bass technique. Hold your toothbrush at a 45-degree angle so the bristles point toward your gumline. Use short, gentle back-and-forth vibrations or tiny circles, letting the bristle tips slip just slightly under the gum edge. After a few seconds on each tooth, sweep the brush away from the gumline to clear loosened debris. This method is specifically designed to dislodge plaque from beneath the gum margin, and for people with mild gum issues, it can reverse early signs of disease on its own.
Electric toothbrushes are equally effective when used properly, and they’re a better option if you have limited hand dexterity or find it hard to maintain the right angle manually. Whichever brush you use, spend about 30 seconds per quadrant of your mouth to hit the two-minute mark.
Clean Between Your Teeth Daily
Brushing alone can’t reach the surfaces between teeth, which is where gum inflammation often starts. Flossing, interdental brushes, or water flossers all help. The evidence for each device ranges from moderate to weak depending on the type, but the consistent finding is that adding any form of interdental cleaning to your brushing routine reduces gingivitis more than brushing alone. Pick whichever method you’ll actually do every day.
Rinse With Salt Water
A warm salt water rinse is one of the simplest ways to calm swollen gums between brushings. The recommended ratio is about one teaspoon of salt (roughly 5 grams) dissolved in a cup of water (250 ml). Swish it around your mouth for about two minutes, then spit. Doing this three times a day helps reduce bacteria and supports healing of irritated gum tissue. Lab studies on human gum cells show that this concentration promotes wound healing without damaging tissue.
Salt water isn’t a replacement for brushing and flossing, but it’s a useful addition, especially when your gums are too tender to tolerate aggressive cleaning.
Use a Cold Compress
If your gums are visibly puffy or painful, holding a cold pack against the outside of your cheek for 10 to 15 minutes can reduce inflammation and numb some of the discomfort. Wrap the ice pack in a cloth to protect your skin. This is a short-term measure that addresses symptoms, not the underlying cause, but it helps while you work on improving your oral hygiene routine.
Try an Antimicrobial Mouthwash
For people at increased risk of gum disease, over-the-counter mouthwashes with certain active ingredients can meaningfully reduce gingivitis. The best-supported options contain either a blend of essential oils (the kind found in products like Listerine, which combines eucalyptol, menthol, methyl salicylate, and thymol) or an ingredient called cetylpyridinium chloride. Toothpastes containing stannous fluoride also show benefits for gum inflammation.
Turmeric-based gels have shown some promise in clinical trials. In one study comparing a turmeric gel to chlorhexidine (a prescription-strength antiseptic rinse), both reduced gum inflammation and bleeding by similar amounts over a month. The turmeric gel actually reduced plaque more than chlorhexidine by the end of the study. That said, these gels aren’t widely available, and the research is still limited compared to established mouthwashes.
When Home Care Isn’t Enough
If your gums are still swollen after one to two weeks of consistent brushing, flossing, and rinsing, you likely need a professional cleaning. Once plaque hardens into tartar, no amount of brushing at home can remove it. A deep cleaning, called scaling and root planing, goes further than a standard dental cleaning. Your dentist or hygienist uses hand instruments or ultrasonic tools to scrape plaque and tartar from above and below the gumline, then smooths the root surfaces so gum tissue can reattach more easily. It’s the only way to clear bacteria that have migrated deep beneath your gums.
This procedure is typically done with local anesthesia and may be split across two visits if the infection is widespread. Some soreness afterward is normal, but most people notice their gums feeling significantly less puffy within a week or two.
Signs That Need Immediate Attention
Most gum swelling is a slow-developing nuisance, not an emergency. But certain symptoms signal a serious infection that’s spreading. Get prompt dental care if you notice any of the following: a visible bump on your gums that looks like an abscess or is leaking pus, swelling that spreads from your gums toward your jaw, neck, or face, fever or a general feeling of being unwell alongside the swelling, severe pain that intensifies rather than fading, or difficulty eating, talking, or swallowing because of the swelling. Facial swelling that progresses toward your throat can compromise your airway, which makes it a genuine emergency.
