Swollen gums usually respond well to a combination of better oral hygiene, simple home remedies, and, when needed, professional cleaning. The most common cause is a buildup of bacterial plaque along the gumline, which triggers inflammation called gingivitis. The good news: gingivitis is reversible if you catch it early. Here’s what to do right now and when the swelling signals something that needs a dentist’s attention.
Why Your Gums Are Swollen
Plaque, a sticky film of bacteria, accumulates on teeth every day. When it isn’t removed thoroughly, it hardens into tarite (calculus) and irritates the gum tissue. This early-stage inflammation is gingivitis. It doesn’t always hurt, which is why many people don’t realize they have it until the swelling becomes visible or their gums bleed during brushing.
If gingivitis goes untreated, it can progress to periodontitis, a deeper infection where gums pull away from the teeth and form pockets that trap more bacteria. Periodontitis damages the bone that holds your teeth in place and can eventually lead to tooth loss. Most swollen gums haven’t reached that point, but the distinction matters because gingivitis can be fully reversed while periodontitis can only be managed.
Plaque isn’t the only trigger. Hormonal shifts during pregnancy cause gum inflammation in 60% to 75% of pregnant women, because rising estrogen and progesterone increase blood flow to the gums and amplify the body’s inflammatory response. Certain medications that cause dry mouth or gum overgrowth can also be responsible. And low vitamin C intake weakens the connective tissue in your gums. A large analysis of over 9,000 people found that low blood levels of vitamin C were linked to increased gum bleeding, even with gentle probing.
Home Remedies That Actually Help
Salt Water Rinse
Dissolve half a teaspoon of salt in a cup of warm water and swish gently for 30 seconds, then spit. The salt draws fluid out of swollen tissue and creates an environment that’s harder for bacteria to thrive in. You can do this two to three times a day, especially after meals.
Cold Compress
If your face or jaw feels puffy alongside the gum swelling, place an ice pack or cold pack on 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 inflammation and numbs the area. This is most useful in the first day or two of noticeable swelling.
Over-the-Counter Pain Relief
Ibuprofen is the better choice over acetaminophen for gum swelling because it targets inflammation directly, not just pain. For mild discomfort, 200 to 400 mg every four to six hours is typically enough. For more significant pain, the American Dental Association notes that combining 400 mg of ibuprofen with 500 mg of acetaminophen every six hours is more effective than either one alone, and even outperforms opioid-based regimens in dental pain studies.
Fix Your Brushing Technique
Most people brush too aggressively or hold the brush flat against their teeth, which misses the gumline entirely. The technique dentists recommend most often is called the Modified Bass method. Hold a soft-bristled toothbrush at a 45-degree angle so the bristles point toward your gumline, not straight at your teeth. Make short, gentle back-and-forth strokes, then sweep the brush away from the gum toward the biting edge of each tooth. This clears bacteria from the narrow gap between your gums and teeth without traumatizing already-inflamed tissue.
If your gums are sore, switch to a soft or extra-soft brush. A hard-bristled brush feels more thorough but actually damages swollen gums and can cause them to recede over time. Floss daily, working the floss gently into the space between each tooth and curving it into a C-shape against the tooth surface. You may see some bleeding at first. That’s the inflammation responding to disturbance, and it typically improves within one to two weeks of consistent flossing.
Nutritional Gaps Worth Checking
Vitamin C plays a direct role in building and maintaining the collagen that gives gum tissue its structure. When intake drops too low, gums become fragile and prone to swelling and bleeding. Severe deficiency causes scurvy, but even mildly low levels are enough to affect your gums. The recommended daily intake is 90 mg for adult men and 75 mg for adult women. Kale, bell peppers, oranges, and kiwis are all rich sources. If your diet is limited, a daily supplement of 100 to 200 mg can help fill the gap.
What a Dentist Can Do
If home care doesn’t reduce the swelling within two weeks, or if you notice your gums pulling away from your teeth, persistent bad breath, or loose-feeling teeth, you likely need professional treatment. The standard procedure is scaling and root planing, often called a deep cleaning. Your dentist or hygienist numbs your gums with a local anesthetic, then uses hand tools or ultrasonic instruments to remove plaque and tartar both above and below the gumline. They also smooth the root surfaces of your teeth so gum tissue can reattach more easily.
The whole process takes one to two hours. Most people return to normal activities the same day. Your gums may feel tender for a couple of days afterward, and your teeth might be sensitive for a month or two as the tissue heals. Teeth can even feel slightly loose right after the cleaning, but that resolves as the gums tighten back up. For moderate to severe periodontitis, your dentist may also prescribe a low-dose antibiotic to take for several months following the procedure.
Swelling During Pregnancy
Pregnancy gingivitis is common enough that most OB-GYNs and dentists consider it a normal side effect of hormonal changes. The surge in progesterone and estrogen increases blood flow to the gums and exaggerates the inflammatory response to even small amounts of plaque. You don’t need to wait until after delivery to address it. Dental cleanings are safe during pregnancy, and staying on top of brushing and flossing is the most effective way to keep swelling under control. The inflammation typically subsides after delivery as hormone levels normalize.
Signs That Need Urgent Attention
Most gum swelling is a slow-building nuisance, not an emergency. But certain combinations of symptoms point to a dental abscess or spreading infection that requires immediate care. If you develop a fever along with facial swelling, go to an emergency room if you can’t reach your dentist that day. Trouble breathing or swallowing alongside gum swelling is a sign the infection may have spread into the jaw, throat, or neck. Tender, swollen lymph nodes under your jaw or along your neck are another red flag. These situations can escalate quickly and shouldn’t wait for a scheduled appointment.
