Swollen gums usually respond well to a combination of better oral hygiene and simple home remedies, often improving within a few days. If the swelling lasts longer than two weeks, though, something deeper is going on and you’ll need professional help. Here’s how to handle it at every stage.
Why Your Gums Are Swollen
The most common cause is gingivitis, the earliest stage of gum disease. Plaque builds up along the gumline, irritating the tissue and triggering inflammation. The telltale signs are red, puffy gums that bleed when you brush or floss. Gingivitis is reversible with good care, which is the good news.
Left untreated, gingivitis can progress to periodontitis, where the gums pull away from the teeth and form pockets that trap bacteria. At this stage you might notice persistent bad breath, receding gums, sensitive or loose teeth, and pain when chewing. Periodontitis requires professional treatment and can lead to tooth loss.
Gum disease isn’t the only explanation. Several other factors can cause or worsen swelling:
- Hormonal changes during pregnancy. A surge in estrogen and progesterone increases blood flow to the gums and heightens their sensitivity to plaque. Pregnancy gingivitis is common enough to have its own name.
- Certain medications. Drugs used for seizures (particularly phenytoin, which causes gum overgrowth in about half the people who take it), some blood pressure medications (especially nifedipine, at roughly 38%), and immunosuppressants like cyclosporine can all trigger gum swelling as a side effect.
- Low vitamin C intake. Vitamin C is essential for maintaining the connective tissue in your gums. A study analyzing data from over 8,000 people found that low blood levels of vitamin C were associated with increased gum bleeding, even with gentle probing.
- A dental abscess. A bacterial infection at the root of a tooth or in the gum tissue can cause localized, painful swelling that needs urgent treatment.
Home Remedies That Actually Help
A saltwater rinse is the simplest and most effective first step. Dissolve 1 teaspoon of salt in 8 ounces of warm water, swish it around your mouth for 15 to 30 seconds, and spit it out. You can do this up to four times a day, including after meals. Salt draws fluid out of swollen tissue and creates an environment that’s harder for bacteria to thrive in.
For pain and inflammation, over-the-counter ibuprofen is the best first choice. Anti-inflammatory pain relievers work well for gum tissue because the pain is driven by inflammation rather than nerve damage. The American Dental Association recommends them as the first-line option for acute dental pain. Taking ibuprofen alongside acetaminophen can provide even stronger relief, as the two work through different mechanisms and have a synergistic effect.
Applying a cold compress to the outside of your cheek (20 minutes on, 20 minutes off) can also reduce swelling and numb discomfort in the short term.
Fix Your Brushing Technique
Most people brush their teeth but miss the gumline entirely, which is exactly where plaque does the most damage. The American Dental Association recommends the Modified Bass technique: hold your toothbrush at a 45-degree angle so the bristles point toward your gumline, then make short, gentle back-and-forth strokes. After that, sweep the brush away from the gumline toward the edge of the tooth. This gets bristles slightly under the gum margin where plaque hides.
Use a soft-bristled brush. Medium or hard bristles can irritate already swollen gums and make things worse. Brush twice a day and floss once daily. If your gums bleed when you floss, that’s not a sign to stop. It’s a sign of inflammation that will improve as you keep flossing consistently over the next week or two. Switch to an alcohol-free mouthwash if you use one, since alcohol dries out the mouth and can aggravate irritated tissue.
What a Dentist Can Do
If your swelling hasn’t improved after two weeks of consistent home care, or if it’s getting worse, it’s time for a professional evaluation. A standard cleaning may be enough for mild gingivitis, removing the hardened plaque (tarite) that you can’t get off with a toothbrush alone.
For periodontitis, the standard treatment is scaling and root planing, often called a deep cleaning. Your gums are numbed with local anesthesia, then the dentist or hygienist removes plaque and tartar from both above and below the gumline using hand instruments or ultrasonic tools. They then smooth the tooth roots so the gum tissue can reattach more easily. The whole process takes one to two hours. Most people return to normal activities the same day, though your gums may feel tender for a couple of days afterward. Antibiotics are sometimes used alongside the procedure to clear stubborn infection.
Swollen Gums During Pregnancy
If you’re pregnant, swollen and bleeding gums are extremely common, especially in the second trimester. The hormonal shifts don’t just increase blood flow to your gums. They also change how your immune system responds to plaque, making even small amounts of buildup more inflammatory than usual.
The treatment approach is the same: thorough brushing, daily flossing, and saltwater rinses. A professional dental cleaning during pregnancy is safe, and dental X-rays are also considered safe with proper shielding. If symptoms are severe, your dentist may prescribe antibiotics or a prescription mouthwash, but check with your OB before starting any new medication. Pregnancy gingivitis typically resolves after delivery as hormone levels return to normal.
If Your Medication Is the Cause
Medication-induced gum overgrowth looks different from regular gingivitis. Instead of just redness and puffiness, the gum tissue actually grows and enlarges, sometimes enough to partially cover the teeth. If you take an anti-seizure medication, a calcium channel blocker for blood pressure, or an immunosuppressant, and you’ve noticed your gums changing, talk to your prescribing doctor. In some cases, switching to a different medication in the same class can resolve the problem. Meticulous oral hygiene slows the overgrowth but may not fully prevent it.
Signs You Need Immediate Care
Most swollen gums are a nuisance, not an emergency. But a dental abscess can become dangerous if infection spreads. Get emergency care if you have difficulty breathing, swallowing, or opening your mouth, if your face or eye is swelling, or if you develop a fever along with significant mouth swelling. These signs suggest the infection is spreading beyond the tooth and gum, and waiting is not safe.
For a suspected abscess without those severe symptoms, you still need to see a dentist urgently rather than trying to manage it at home. Abscesses don’t resolve on their own. Saltwater rinses and pain relievers can help you manage discomfort while you wait for your appointment, but they won’t clear the infection.
