Swollen gums are almost always a sign of inflammation, and the fastest way to treat them depends on what’s causing the swelling. In most cases, a combination of home care and improved oral hygiene will resolve mild gum swelling within one to two weeks. More persistent or severe swelling may need professional treatment.
What’s Causing the Swelling
The most common cause is plaque buildup along and under the gumline. When bacteria-laden plaque sits on your teeth for too long, your immune system responds with inflammation: red, puffy gums that bleed easily when you brush or floss. This is gingivitis, the earliest and most treatable stage of gum disease.
Left alone, gingivitis can progress to periodontitis, a more serious condition where gums pull away from the teeth and form deep pockets that trap even more bacteria. Signs that you’ve crossed that line include gums that bleed during gentle brushing, persistent bad breath that doesn’t respond to brushing or mouthwash, teeth that feel loose or shift position, and pus between the teeth and gums. Periodontitis can damage the bone supporting your teeth, so it needs professional care.
Other common triggers for swollen gums include a developing abscess (a pocket of infection at the tooth root), hormonal shifts during pregnancy, vitamin deficiencies, a new medication, or simple irritation from a piece of food wedged under the gumline.
Immediate Relief at Home
A saltwater rinse is one of the simplest and most effective first steps. Mix half a teaspoon of salt into one cup of warm (not hot) water, swish gently for 30 seconds, and spit. Do this once or twice a day, especially after meals. Salt draws fluid out of swollen tissue and creates an environment that’s harder for bacteria to thrive in.
If your face or jaw is visibly swollen, apply a cold pack to the outside of your cheek for 10 to 20 minutes at a time, with a thin cloth between the ice and your skin. Cold reduces blood flow to the area and helps bring down swelling. Avoid heat on an active infection, as warmth can increase swelling and encourage bacterial growth.
Over-the-counter ibuprofen (400 mg every six hours) is effective for reducing both pain and inflammation in gum tissue. Naproxen is another option at 250 mg every six hours or 500 mg every 12 hours. These work better for oral inflammation than acetaminophen, which relieves pain but doesn’t target swelling directly.
Improving Your Daily Oral Hygiene
If plaque is the root cause, no rinse or painkiller will fix the problem long-term. The American Dental Association recommends brushing twice a day with fluoride toothpaste and cleaning between your teeth once a day with floss or an interdental cleaner. That “once a day” flossing step is the one most people skip, and it’s often the reason gums stay inflamed. Plaque hardens into tartar within about 24 to 72 hours, and tartar can only be removed by a dental professional.
If your gums are tender right now, use a soft-bristled toothbrush and be gentle but thorough. Switching to an electric toothbrush can help you remove more plaque with less pressure. Don’t stop brushing or flossing the swollen area. It might bleed at first, but consistent cleaning is what allows the tissue to heal. Most cases of mild gingivitis improve noticeably within 10 to 14 days of diligent brushing and flossing.
When You Need Professional Treatment
If swelling persists for more than two weeks despite good home care, or if you notice gum recession, loose teeth, or pus, you likely need a deep cleaning. The professional term is scaling and root planing. Your dentist or hygienist numbs the area with local anesthesia, then uses hand instruments or ultrasonic tools to remove plaque and tartar from below the gumline. After scraping away the buildup, they smooth the tooth roots so gums can reattach more easily. Antibiotics may be placed directly around the roots or prescribed as a short oral course.
This procedure is the only way to remove bacteria trapped deep in gum pockets. Once the infection clears, swollen gums shrink back toward a healthier shape. You may need follow-up visits to check pocket depth and ensure the tissue is healing properly.
Nutritional Factors That Affect Gum Health
Low vitamin C levels are directly linked to gum bleeding and swelling. A review covered by Harvard Health Publishing found that low blood levels of vitamin C were associated with increased gum bleeding, even with gentle probing. Severe deficiency (scurvy) causes widespread bleeding throughout the body, but even moderate shortfalls can make your gums more vulnerable to inflammation.
The recommended daily intake for adult men is 90 mg and 75 mg for women. If your diet is low in fruits and vegetables, adding foods like bell peppers, kiwis, oranges, strawberries, and kale can help. A daily supplement of 100 to 200 mg of vitamin C is another option. This won’t replace brushing and flossing, but it supports the tissue integrity your gums need to resist bacterial damage.
Pregnancy and Hormonal Swelling
Pregnancy gingivitis affects a large number of pregnant women, typically starting in the second trimester. Rising progesterone levels amplify the body’s inflammatory response to plaque bacteria, so even women with good oral hygiene can develop red, puffy, bleeding gums. The hormone shift also creates conditions that encourage bacterial growth around the gumline.
The swelling usually resolves after delivery as hormone levels normalize, but it shouldn’t be ignored during pregnancy. Untreated gum inflammation can worsen over the remaining months. Gentle brushing, daily flossing, and regular dental cleanings during pregnancy are all safe and recommended. Let your dentist know you’re pregnant so they can adjust your care plan.
Signs That Need Emergency Care
Most gum swelling is manageable at home or with a scheduled dental visit, but certain symptoms signal a spreading infection that requires immediate attention. Go to an emergency room if you have a fever combined with facial swelling and can’t reach your dentist. Difficulty breathing or swallowing is another red flag. These symptoms suggest the infection has moved beyond the gum tissue into your jaw, throat, or neck, where it can become life-threatening without prompt treatment.
