Swollen gums usually start improving within a few days of consistent care at home, and most cases of mild gum inflammation resolve in about two weeks. The fastest way to bring the swelling down depends on what’s causing it, but a combination of better brushing, saltwater rinses, and an anti-inflammatory pain reliever will handle the majority of cases. Here’s what works, what to watch for, and when the swelling signals something more serious.
Why Your Gums Are Swollen
The most common cause is plaque buildup along the gumline. When bacteria-laden plaque sits on your teeth, your immune system responds with inflammation, turning your gums red, puffy, and tender. This is gingivitis, and it’s the starting point for the vast majority of gum swelling people experience.
Hormonal changes can amplify the problem. During pregnancy, rising estrogen and progesterone increase blood flow to the gums and make them more sensitive to plaque. Pregnancy gingivitis affects 60% to 75% of pregnancies in the U.S. Certain medications, particularly those for seizures, high blood pressure, and immune suppression, can also cause gum tissue to enlarge on its own.
Less commonly, a vitamin C deficiency weakens the connective tissue in your gums. Your body needs vitamin C to build collagen, the structural protein that holds gum tissue together. Without enough of it, gums become fragile, swollen, and prone to bleeding. It takes surprisingly little to prevent this: just 10 mg of vitamin C daily is enough to ward off deficiency, though most adults benefit from far more through a normal diet of fruits and vegetables.
Saltwater Rinses
A warm saltwater rinse is the simplest thing you can do right now. Salt draws fluid out of swollen tissue and creates an environment that’s less hospitable to bacteria. Mix one teaspoon of salt into about one cup (250 ml) of warm water, swish it around your mouth for 30 seconds, and spit. Do this two to three times a day, ideally after meals and before bed.
Saltwater won’t fix the underlying cause, but it reliably reduces puffiness and discomfort while you address the root problem.
Over-the-Counter Pain Relief
If your gums are painful along with being swollen, ibuprofen is a better choice than acetaminophen. Ibuprofen is an anti-inflammatory, meaning it targets the inflammation driving the swelling, not just the pain signal. The American Dental Association recommends NSAIDs like ibuprofen as first-line therapy for dental pain because they address the source of the problem.
For mild gum pain, 200 to 400 mg of ibuprofen every four to six hours as needed is standard. For moderate pain, 400 mg on a fixed schedule every six hours for the first 24 hours tends to stay ahead of the inflammation cycle. You can also combine ibuprofen with acetaminophen for stronger relief. An FDA-approved combination pairs 250 mg of ibuprofen with 500 mg of acetaminophen per dose, taken every six hours.
Cold Compress for Quick Relief
Placing something cold against your cheek, over the swollen area, constricts blood vessels and reduces swelling from the outside. Use an ice pack or a bag of frozen vegetables wrapped in a thin cloth. Hold it against your face for 10 to 20 minutes at a time, then remove it. You can repeat this several times throughout the day. This works especially well when swelling is acute, such as after a dental procedure or when an infection is flaring up.
Improve Your Brushing and Flossing
If plaque buildup caused the swelling, no rinse or compress will fix it permanently. You need to physically remove the plaque. Use a soft-bristled toothbrush, which the American Dental Association recommends for everyone, and brush for a full two minutes twice a day. If your gums are already inflamed or you’ve been diagnosed with gum disease, soft bristles are especially important because harder bristles can tear delicate tissue and make things worse.
Floss daily, gently working the floss below the gumline in a C-shape around each tooth. The first few days of consistent flossing after a break will likely cause some bleeding. That’s normal and typically stops within a week as the inflammation decreases. If you find traditional floss painful, a water flosser or interdental brushes are effective alternatives that are easier on tender gums.
Antiseptic Mouthwash
For persistent gum swelling, a prescription chlorhexidine mouthwash is one of the most effective tools available. It kills the bacteria responsible for gingivitis and directly reduces redness, swelling, and bleeding. Your dentist can prescribe it for short-term use.
The tradeoff is cosmetic: chlorhexidine commonly causes brown staining on teeth, fillings, and dentures, along with increased tartar buildup and temporary changes in taste. In some cases the staining can be difficult to remove. For this reason, it’s typically used as a short course to get inflammation under control rather than as a long-term daily rinse. Over-the-counter antiseptic mouthwashes with cetylpyridinium chloride or essential oils are gentler alternatives for ongoing use, though less potent.
How Long Swelling Takes to Go Down
With consistent brushing, flossing, and rinsing, most cases of gingivitis-related swelling improve noticeably within a few days and heal fully in about two weeks. The timeline depends on severity. If plaque has been building for months, you may need a professional cleaning before home care can finish the job.
If your gums were significantly swollen before a deep cleaning (scaling and root planing), expect them to shrink back as the infection clears. Your teeth might even feel slightly loose temporarily because the puffy tissue that was pressing against them has receded. This resolves as the gums tighten back up around the teeth.
When Swelling Means Something Serious
Not all gum swelling is simple gingivitis. A dental abscess, which is a pocket of infection, produces swelling that feels different and behaves differently. With an abscess, pain is often intense and localized to one tooth. The tooth may feel loose, raised slightly in its socket, or sensitive to heat, cold, and pressure. You might notice a small red bump on your gum (called a gum boil) where the infection is draining, or swelling that extends into your jaw, cheek, or neck. Fever, swollen lymph nodes, and feeling generally unwell are common.
Seek urgent dental care if you notice any of these signs:
- A hard lump or severe swelling on your gums or face
- Fever above 101.4°F (38°C)
- Tender, swollen lymph nodes in your neck
- Bleeding that doesn’t stop
Go to an emergency room if swelling spreads to your neck or around your eyes, if you have difficulty breathing or swallowing, if you can barely open your mouth, or if pain is uncontrollable with over-the-counter medication. A dental abscess that spreads can become life-threatening, and these symptoms indicate the infection may be moving beyond the tooth.
Professional Treatment Options
If two weeks of diligent home care hasn’t resolved the swelling, a dental visit is the next step. Your dentist will check for tartar (hardened plaque) below the gumline that brushing and flossing can’t reach. If it’s there, you’ll need scaling and root planing, sometimes called a deep cleaning. This involves clearing bacteria and tartar from the root surfaces of your teeth so your gums can reattach to clean surfaces.
For gum swelling caused by medications, your dentist may coordinate with your prescribing doctor to adjust the drug or dosage. Pregnancy-related swelling generally improves after delivery as hormone levels normalize, but regular cleanings during pregnancy help keep it manageable. If a vitamin deficiency is suspected, increasing your intake of vitamin C through citrus fruits, bell peppers, strawberries, or a supplement can reverse gum symptoms relatively quickly once levels are restored.
