Swollen gums usually respond well to a combination of home care and over-the-counter treatments. A salt water rinse is the simplest starting point, while anti-inflammatory pain relievers like ibuprofen can reduce both the swelling and discomfort. What works best depends on what’s causing the inflammation, so understanding your options helps you pick the right approach.
Salt Water Rinse
A warm salt water rinse is the fastest, cheapest remedy you can try right now. Mix 1 teaspoon of salt into 8 ounces of warm water and stir until it dissolves. Swish it around your mouth for 30 seconds, then spit. You can do this several times a day. If it stings or feels too strong, cut back to half a teaspoon. Studies have found that rinses with 0.9% to 1.8% salt concentration promote gum healing and recovery.
Salt water works by drawing fluid out of inflamed tissue through osmosis, which temporarily reduces swelling. It also creates an environment that’s harder for bacteria to thrive in. This won’t fix the underlying problem, but it’s a solid first step while you figure out what’s going on.
Anti-Inflammatory Pain Relievers
NSAIDs like ibuprofen and naproxen are the most effective over-the-counter option for gum swelling because they work directly at the site of inflammation. They block the chemical signals your body uses to create swelling and pain, which means they’re treating both symptoms at once. The American Dental Association recommends NSAIDs as first-line therapy for acute dental pain for exactly this reason.
Acetaminophen works differently. It blocks pain signals in the brain rather than reducing inflammation in your gums. That makes it less useful on its own for swelling, but combining it with an NSAID can be highly effective because you’re targeting pain from two different directions. If ibuprofen alone isn’t cutting it, adding acetaminophen (at their respective recommended doses) is a well-supported strategy.
Topical Numbing Gels
Over-the-counter benzocaine gels (typically 20% concentration) numb the gum tissue on contact. Apply a pea-sized amount directly to the swollen area up to four times daily. These don’t reduce the actual swelling, but they make it much more bearable while other treatments take effect. Look for products labeled for oral pain at any pharmacy.
Keep in mind that numbing gels are a short-term fix. If you’re reaching for one repeatedly over several days, the underlying cause needs attention.
Hydrogen Peroxide Rinse
A diluted hydrogen peroxide rinse kills bacteria and can help with gum inflammation. Start with the standard 3% hydrogen peroxide you’ll find at any drugstore, then mix equal parts peroxide and water to bring it down to 1.5%. Swish for 30 to 60 seconds and spit it out completely. Never swallow the mixture, and don’t rinse for longer than 90 seconds, as prolonged contact can irritate soft tissue.
Cold Compress
If your swelling is visible from the outside or you’re dealing with significant pain, apply an ice pack or cold compress to the outside of your cheek. Keep it on for 10 to 20 minutes at a time with a thin cloth between the ice and your skin. Cold constricts blood vessels and slows the inflammatory process, which helps with both puffiness and throbbing pain. This is especially useful for swelling caused by an abscess or injury.
Vitamin C
Low vitamin C levels are directly linked to an increased risk of gum bleeding and inflammation. Research from Harvard Health found that people with low bloodstream levels of vitamin C were significantly more likely to experience gum bleeding, even with gentle probing. The recommended daily intake for adult men is 90 mg, but experts suggest aiming for 100 to 200 mg daily through foods like bell peppers, kiwis, oranges, and kale, or through a supplement. If your diet has been lacking in fruits and vegetables, this could be a contributing factor worth addressing.
Tea Tree Oil
Tea tree oil has antimicrobial properties, but it requires careful handling. Never apply it directly to your gums undiluted. Mix one or two drops into warm water or blend it with a carrier oil like coconut oil. Swish for about 30 seconds, spit it out completely, and follow up with a plain warm water rinse. Limit use to once a day and no more than three times a week. Some people experience a burning sensation. If that happens, stop using it. Keep it away from children.
Prescription Mouthwash
If home remedies aren’t resolving things, your dentist may prescribe chlorhexidine mouthwash. This is a step up from anything available over the counter. Chlorhexidine destroys the bacteria that cause gingivitis and directly reduces redness, swelling, and bleeding. The typical dose is 15 milliliters swished for 30 seconds, twice a day. It’s prescription-only, so you’ll need a dental visit to get it.
What’s Likely Causing the Swelling
The most common cause is gingivitis, an early stage of gum disease driven by bacterial plaque buildup between brushings. At this stage, the damage is reversible. Your gums are inflamed but the underlying bone and tissue are intact. Improving your brushing and flossing routine, combined with the remedies above, can resolve mild gingivitis within a couple of weeks.
If gingivitis goes untreated, it can progress to periodontitis. At this stage, gums pull away from the teeth, teeth may feel loose or shift position, chewing becomes painful, and you may notice persistent bad breath. Periodontitis involves damage below the gumline that home care alone can’t fix.
Other causes of swollen gums include hormonal changes (pregnancy, menstruation), a new medication, a food particle trapped under the gumline, an ill-fitting dental appliance, or a dental abscess. An abscess typically causes localized, intense swelling and may involve fever or pus, which needs prompt professional treatment.
Professional Deep Cleaning
When swollen gums don’t respond to home care, or when a dentist identifies significant plaque and tartar buildup below the gumline, the standard treatment is scaling and root planing. This is a deep cleaning that goes further than a routine dental visit. Your gums are numbed with local anesthesia, then a dentist or hygienist uses hand instruments or ultrasonic tools to remove plaque and tartar from both above and below the gumline. The root surfaces of your teeth are then smoothed to prevent bacteria from reattaching easily.
After the procedure, your gums will likely shrink back to a healthier position as the infection clears. Some people experience temporary sensitivity and mild discomfort for a few days. For many patients with moderate gum disease, this single procedure combined with better daily care is enough to turn things around.
Signs That Need Prompt Attention
Swollen gums that bleed when you brush, feel tender, or look redder than usual are worth monitoring and treating at home for a week or two. But certain symptoms point to something more serious. Gums that have pulled away from your teeth, loose or shifting teeth, pain while chewing, pus along the gumline, or fever alongside the swelling all indicate that the problem has moved beyond what home remedies can manage. Persistent bad breath that doesn’t improve with better oral hygiene is another signal that bacteria have established themselves deeper than a toothbrush can reach.
