Anti-inflammatory pain relievers like ibuprofen and naproxen are the most effective over-the-counter medicines for swollen gums because they reduce both pain and inflammation at the source. But the “best” medicine depends on what’s causing the swelling. A saltwater rinse may be all you need for mild irritation, while a bacterial infection requires prescription antibiotics. Here’s how to match the right treatment to your situation.
Anti-Inflammatory Pain Relievers
Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and naproxen are the go-to choice for gum swelling because they do two things at once: block pain signals and reduce the inflammatory process that causes tissue to puff up. Acetaminophen (Tylenol) helps with pain but is weaker at controlling inflammation. In a clinical trial published in Frontiers in Pharmacology, patients who took naproxen after oral surgery had significantly lower levels of a key inflammatory marker in their blood compared to those who took acetaminophen. Six hours after the procedure, the acetaminophen group’s inflammatory marker had risen roughly 519% from baseline, while the naproxen group’s had risen only about 277%.
If you’re reaching for something at the pharmacy, ibuprofen (Advil, Motrin) or naproxen (Aleve) will do more for visible gum swelling than acetaminophen alone. Take them with food to protect your stomach, and follow the dosing instructions on the label. These aren’t a long-term fix, though. If you’re still relying on them after a few days, something deeper is going on.
Topical Numbing Gels
Benzocaine gels (like Orajel) numb the sore area on contact and can make swollen gums much more tolerable while you address the underlying cause. Apply the gel directly to the affected gum tissue up to four times a day. Don’t use it for more than two consecutive days without seeing a dentist, as prolonged use can mask a worsening problem. These gels don’t reduce swelling, so think of them as comfort care rather than treatment.
Saltwater Rinses
A warm saltwater rinse is one of the simplest and most reliable home remedies for mild gum swelling. Salt draws fluid out of inflamed tissue, which helps reduce puffiness, and it creates an environment that’s harder for bacteria to thrive in. The standard recipe is 1 teaspoon of salt dissolved in 8 ounces of warm water. If your gums are especially tender, start with half a teaspoon for the first day or two. Swish the solution around your mouth for about 30 seconds, then spit it out. You can repeat this several times a day.
Saltwater won’t cure an infection or reverse gum disease, but it’s a safe first step that can calm things down while you figure out your next move.
Antiseptic Mouthwash
For swelling caused by gingivitis (the earliest stage of gum disease), a prescription-strength antiseptic mouthwash containing chlorhexidine is one of the most effective treatments available. It kills the bacteria that trigger gum inflammation and is typically used as a 15-milliliter rinse, swished for 30 seconds, twice daily. Use it after brushing and flossing, and rinse all toothpaste out of your mouth with plain water first. Avoid eating or drinking for several hours afterward so the active ingredient stays in contact with your gum tissue.
Chlorhexidine requires a prescription in most cases. Over-the-counter antiseptic mouthwashes with cetylpyridinium chloride offer a milder alternative, but they aren’t as potent for active gum disease.
Prescription Antibiotics
When gum swelling is caused by a bacterial infection, particularly one that produces pus, causes a fever, or spreads to nearby tissue, antibiotics are necessary. Dentists most commonly prescribe amoxicillin or penicillin V as a first choice. If those don’t work or you’re allergic to penicillin, alternatives include cephalexin, metronidazole, azithromycin, or clindamycin for stubborn infections. A typical course lasts at least a full week.
Antibiotics treat the infection, but they don’t fix the structural problem that allowed bacteria to accumulate. That’s why they’re almost always paired with a professional cleaning or other dental procedure.
Why the Cause Matters
Swollen gums aren’t a single condition. They’re a symptom, and different causes call for different medicines. The most common culprit is plaque buildup along the gumline, which triggers gingivitis. Gingivitis makes gums red, puffy, and prone to bleeding when you brush. The good news is that it’s fully reversible with professional cleaning and consistent home care.
Left untreated, gingivitis can progress to periodontitis, a more serious form of gum disease where bacteria spread below the gumline and start breaking down the bone and tissue that hold your teeth in place. Gums pull away from the teeth, forming deep pockets that trap more bacteria. Eventually, teeth loosen. At this stage, no over-the-counter medicine can fix the problem. You need professional treatment.
Other causes of gum swelling include hormonal changes during pregnancy (pregnancy gingivitis affects a large number of expectant mothers), an emerging wisdom tooth, a poorly fitting dental appliance, or a localized abscess. Each of these may respond to different treatments.
Vitamin C and Gum Health
Low vitamin C intake is a surprisingly common contributor to gum problems. Harvard Health reports that insufficient vitamin C is linked to gum bleeding and swelling, and that boosting your intake can improve symptoms. The recommended daily amount for adult men is 90 mg, and experts suggest aiming for 100 to 200 mg through foods like oranges, bell peppers, kiwis, and kale, or through a supplement. This won’t replace treatment for an active infection, but if your gums are chronically inflamed and your diet is low in fruits and vegetables, a vitamin C boost is worth trying.
Swollen Gums During Pregnancy
Pregnancy hormones increase blood flow to your gums and make them more sensitive to plaque, which is why many pregnant women develop gingivitis even with good brushing habits. The safest approach is a professional dental cleaning to remove plaque, along with daily home care: brushing twice a day, flossing once, and rinsing with warm saltwater (1 teaspoon of salt in 1 cup of warm water). An alcohol-free mouthwash is another safe option. If symptoms are severe, a dentist may prescribe antibiotics or a medicated rinse, but it’s important to check with your prenatal care provider before starting any new medication during pregnancy.
Signs You Need Professional Treatment
Home remedies and OTC medicines work well for mild, short-lived gum swelling. But certain signs point to a problem that won’t resolve on its own:
- Bleeding during brushing, flossing, or eating
- Gums pulling away from your teeth, making them look longer
- Pus between your gums and teeth
- Loose teeth or a change in your bite
- Persistent bad breath that doesn’t improve with brushing
- Sores inside your mouth
Any of these warrants a dental visit. Gum disease is often painless in its early stages, so the absence of severe pain doesn’t mean things are fine. A periodontist can assess the depth of gum pockets and determine whether you’re dealing with simple gingivitis or more advanced disease that needs scaling, root planing, or other intervention.
