Gum swelling usually responds well to a combination of home care and, when needed, professional dental treatment. The right approach depends on what’s causing the inflammation, whether that’s plaque buildup, a trapped piece of food, hormonal changes, or an infection that’s already taken hold. Most mild cases improve within a few days of consistent care at home, but swelling that persists beyond a week or comes with fever, pus, or loose teeth signals something more serious.
Start With a Salt Water Rinse
A warm salt water rinse is the simplest and most effective first step. Dissolve half a teaspoon of salt in a cup of warm water, swish it gently around the swollen area for 30 seconds, then spit it out. The salt draws fluid out of inflamed tissue and creates an environment that’s harder for bacteria to thrive in. You can repeat this several times a day, especially after meals.
This won’t cure an infection on its own, but it reduces bacterial load and soothes irritated tissue while you figure out next steps. It’s also one of the safest options during pregnancy, when many medications are off the table.
Use Cold Compresses and Anti-Inflammatories
If your gum swelling is causing visible puffiness along your jaw or cheek, apply an ice pack or cold compress to the outside of your face for 10 to 20 minutes at a time, with a thin cloth between the ice and your skin. This constricts blood vessels and reduces both swelling and pain. Remove it for at least 20 minutes before reapplying.
Over-the-counter ibuprofen works well for dental inflammation because it targets both pain and swelling. The standard adult dose is 400 milligrams every four to six hours as needed. Ibuprofen is generally more effective than acetaminophen for gum-related pain because of its anti-inflammatory properties, though you can alternate the two if one alone isn’t enough.
Improve Your Brushing and Flossing Technique
The most common cause of swollen gums is plaque, the sticky film of bacteria that builds up along the gumline. When plaque isn’t removed, it hardens into tartar and triggers an inflammatory response. Brushing twice daily with a soft-bristled toothbrush and flossing once a day is the baseline for keeping gums healthy, but technique matters as much as frequency.
Angle your toothbrush at 45 degrees toward the gumline and use short, gentle strokes. Aggressive brushing can actually injure swollen tissue and make things worse. When flossing around a swollen area, curve the floss into a C-shape against each tooth and slide it gently below the gumline rather than snapping it straight down. You may see some bleeding at first, which is normal with inflamed gums and typically decreases within a week or two of consistent flossing.
Know the Difference Between Gingivitis and Periodontitis
Gingivitis is the earliest stage of gum disease. It causes mild redness, swelling, and occasional bleeding when you brush. The good news is that gingivitis is fully reversible with better oral hygiene and a professional cleaning. No permanent damage has occurred at this stage.
Periodontitis is what happens when gingivitis goes untreated. The swelling becomes more severe, gums start pulling away from the teeth to form deep pockets, and the bone supporting your teeth begins to break down. Warning signs include bleeding during gentle brushing, gums that have visibly receded, teeth that feel loose or shift when you bite, and pus between the teeth and gums. Pus is a clear indicator that infection has reached an advanced stage. Once periodontitis develops, you can’t reverse the damage at home. You need professional treatment to stop it from progressing.
When You Need a Deep Cleaning
If your swelling is caused by tartar buildup below the gumline, a regular cleaning won’t reach it. Your dentist will recommend scaling and root planing, commonly called a deep cleaning. This procedure uses hand instruments or ultrasonic tools to remove plaque and tartar from both above and below the gumline, then smooths the root surfaces so gums can reattach more easily.
You’ll receive local anesthesia to numb the area, so the procedure itself isn’t painful. Afterward, your gums may feel tender for a few days. As the infection clears, swollen gums shrink back and tighten around the teeth. This means you may notice more of your tooth roots showing, which can look a bit different but is a sign that healing is happening. Teeth sometimes feel slightly loose right after the procedure, but this resolves as the gums firm up. Your dentist may also prescribe antibiotics, either applied directly to the gum pockets or taken orally, to help clear remaining bacteria.
Medicated Mouthwash for Persistent Inflammation
For gum swelling that doesn’t fully resolve with home care, your dentist may prescribe a medicated rinse containing chlorhexidine at a 0.12% concentration. This is a powerful antimicrobial that kills bacteria on contact and continues working for hours after you rinse. It’s significantly more effective than over-the-counter mouthwash at reducing the bacterial colonies that cause gum disease.
The tradeoff is tooth staining. In clinical testing, about 56% of users showed a measurable increase in staining after six months, and 15% developed heavy staining. The staining is more noticeable if you have plaque buildup that hasn’t been professionally removed. For this reason, chlorhexidine is typically prescribed for limited periods rather than as a permanent addition to your routine, and your dentist should reevaluate your progress at intervals of no longer than six months.
Gum Swelling During Pregnancy
Pregnancy gingivitis affects a large number of expectant mothers, typically appearing in the second or third trimester. The cause is a surge in estrogen and progesterone, which increases blood flow to the gums, makes them more sensitive to plaque, and triggers inflammation even with normal brushing habits. Gums may appear red, puffy, and bleed easily.
The safest approach is a professional dental cleaning to remove plaque, combined with diligent home care: brushing twice daily, flossing once daily, and gargling with a warm salt water rinse (one teaspoon of salt in a cup of warm water). Use alcohol-free mouthwash rather than standard formulas. If symptoms are severe or worsening, your dentist may prescribe antibiotics or a prescription mouthwash, but you should check with your pregnancy care provider before starting any new medication.
Signs That Swelling Is an Emergency
Most gum swelling is uncomfortable but not dangerous. However, certain symptoms indicate the infection may be spreading beyond the gum tissue into the jaw, throat, or neck, and these require urgent care:
- Fever combined with facial swelling: this suggests the infection has entered the bloodstream or surrounding tissues
- Difficulty breathing or swallowing: swelling in the throat can compromise your airway
- Swollen, tender lymph nodes under your jaw or along your neck
- Swelling spreading to your cheek, eye, or neck
If you develop fever and facial swelling and can’t reach your dentist, go to an emergency room. Difficulty breathing or swallowing is always an emergency, regardless of the time of day. A dental abscess that spreads can become life-threatening if bacteria enter the bloodstream or block the airway, so these symptoms should never be managed at home.
