Swollen gums usually respond well to a few days of consistent home care, starting with saltwater rinses and improved brushing habits. Most mild gum swelling is caused by plaque buildup triggering your body’s inflammatory response, and removing that plaque is the single most effective way to bring the swelling down. If your gums are still puffy after a week of diligent care, something deeper is likely going on.
Why Your Gums Are Swollen
When plaque sits on your teeth and along the gumline for more than a few days, the bacterial film disrupts the normal balance of microbes in your mouth. Your immune system responds with inflammation, sending extra blood flow and fluid to the area. That’s the puffiness, redness, and tenderness you’re feeling. This early stage is called gingivitis, and it’s reversible.
Plaque isn’t the only trigger. Hormonal shifts, especially during pregnancy, puberty, and menstruation, make gums more reactive. Estrogen and progesterone increase blood vessel permeability in gum tissue, meaning fluid leaks into the surrounding area more easily. Pregnancy gingivitis can start as early as the first trimester and often peaks in the second or third, though gums typically return to normal after delivery.
Certain prescription medications also cause gum overgrowth as a side effect. The most common culprits are seizure medications (particularly phenytoin, which causes gum enlargement in roughly 50% of users), the immune-suppressing drug cyclosporine (about 30% of users), and blood pressure medications in the calcium channel blocker family like nifedipine and amlodipine (about 20% of users). If your swelling started after beginning a new medication, that’s worth flagging with your prescriber.
Saltwater Rinses
A warm saltwater rinse is the simplest and fastest way to start pulling swelling down. Mix one teaspoon of salt into eight ounces of warm water. If your gums are very tender, cut the salt to half a teaspoon for the first day or two. Swish the solution around your mouth for 30 seconds, spit it out, and repeat at least three times a day. Don’t rinse more than four or five times daily, as too much salt can irritate already-inflamed tissue.
Saltwater works by drawing excess fluid out of swollen gum tissue through osmosis and creating a temporarily less hospitable environment for bacteria. You won’t see dramatic results in an hour, but most people notice reduced puffiness within two to three days of consistent rinsing.
Cold Compresses for Quick Relief
If the 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. Place a thin cloth between the ice and your skin to prevent irritation. You can repeat this every few hours. Cold narrows blood vessels and slows the flow of inflammatory fluid into the tissue, which reduces both swelling and pain.
Brushing and Flossing Technique
This is the part most people skip because swollen gums hurt to brush. But avoiding the area lets more plaque accumulate, which makes the swelling worse. Use a soft-bristled toothbrush and brush gently along the gumline at a 45-degree angle, twice a day. The goal is to sweep plaque away from where the gum meets the tooth without scrubbing hard enough to cause more irritation.
Floss once daily, even if your gums bleed. Bleeding during flossing when your gums are inflamed is normal and actually a sign that the area needs more attention, not less. Slide the floss gently between teeth and curve it into a C-shape against each tooth, moving it up and down rather than snapping it against the gum. An alcohol-free mouthwash can help as a final step by reaching areas your brush and floss miss.
Check Your Vitamin C Intake
Low vitamin C levels are linked to gum bleeding and swelling because the vitamin plays a direct role in maintaining connective tissue, including the tissue that holds your teeth in place. The recommended daily intake for adult men is 90 mg and 75 mg for women. Harvard Health suggests aiming for 100 to 200 mg daily through foods like bell peppers, kiwis, oranges, strawberries, and kale, or through a supplement if your diet falls short. If your gums are chronically puffy despite good oral hygiene, a vitamin C deficit is worth considering.
When Home Care Isn’t Enough
If your gums haven’t improved after 7 to 10 days of saltwater rinses, thorough brushing, and flossing, you likely have tartar buildup that can’t be removed at home. Tartar is hardened plaque that bonds to your teeth and sits below the gumline, keeping your gums perpetually inflamed no matter how well you brush.
A professional deep cleaning, called scaling and root planing, removes this buildup. Your dentist or hygienist numbs your gums with local anesthesia, then uses hand tools or ultrasonic instruments to scrape plaque and tartar from both above and below the gumline. They also smooth the root surfaces so gums can reattach more tightly. The procedure takes one to two hours and may be split across two visits. Your dentist may also place antibiotics around the roots or prescribe oral antibiotics afterward to control any remaining infection.
Pregnancy-Related Swelling
If you’re pregnant, a professional dental cleaning is the primary treatment for reducing gum inflammation, and it’s considered safe throughout pregnancy. X-rays with proper shielding are also safe. At home, follow the same protocol: brush twice daily, floss once daily, and rinse with warm saltwater. Use alcohol-free mouthwash. If symptoms are severe or worsening, your dentist may recommend antibiotics or prescription mouthwash, but check with your pregnancy care provider before starting any medication.
Signs of Something More Serious
Simple gum swelling from plaque is uncomfortable but not dangerous. A dental abscess is. The key differences: abscess pain tends to be sharp and gets worse when you bite down, you may notice a bad taste from pus draining in your mouth, the affected tooth can feel loose or like it’s sitting higher than the others, and you might see a visible raised bump on the gum near the root of the tooth.
If swelling spreads to your face, neck, or under your jaw, or if you develop a fever, fatigue, or swollen lymph nodes, the infection may be spreading beyond the tooth. An untreated abscess can progress to a serious head and neck infection or, in rare cases, sepsis. These symptoms need same-day dental or medical attention.
Medication-Related Gum Overgrowth
If your swelling is caused by a medication side effect, home remedies will only do so much. The overgrowth happens because the drug changes how your gum tissue produces collagen, leading to excess tissue that piles up around the teeth. Meticulous oral hygiene can slow the progression, and professional cleanings help manage it, but the swelling often won’t fully resolve unless the medication is changed. Talk to the prescribing doctor about alternatives rather than stopping any medication on your own. In severe cases, a dentist can surgically remove the excess gum tissue, though it may regrow if the medication continues.
