Swollen gums usually respond well to a combination of home care, over-the-counter products, and basic oral hygiene adjustments. The right approach depends on what’s causing the swelling, but a warm saltwater rinse is the simplest and most effective starting point for nearly everyone. Beyond that, you have several options ranging from topical pain relievers to anti-inflammatory medications to professional dental cleaning.
Saltwater Rinse
A saltwater rinse works by drawing excess fluid out of swollen gum tissue through osmosis, which reduces puffiness and discomfort. Mix half a teaspoon of salt into one cup of warm (not hot) water and swish gently for 30 seconds before spitting. You can repeat this two to three times a day. Sea salt and Himalayan salt both work, though regular table salt is fine too.
This is one of the few remedies that’s safe for virtually everyone, including pregnant women. Cleveland Clinic specifically recommends a warm saltwater rinse as part of daily care during pregnancy-related gum swelling, using one teaspoon of salt per cup of warm water.
Over-the-Counter Pain Relievers
Ibuprofen is particularly useful for swollen gums because it reduces both pain and inflammation. The standard adult dose is 400 milligrams every four to six hours as needed. It won’t fix the underlying cause, but it can make the swelling noticeably more comfortable while you address what’s going on.
If you can’t take ibuprofen due to stomach sensitivity or other reasons, acetaminophen will help with pain but won’t do much for the inflammation itself.
Topical Numbing Gels and Clove Oil
For localized pain, you can apply a numbing gel containing benzocaine directly to the swollen area. A study published in the Journal of Dentistry found that clove gel performed just as well as benzocaine for pain relief, with no significant difference in pain scores between the two. Clove oil contains eugenol, a natural compound with both numbing and mild antiseptic properties.
Both options can cause a slight burning sensation during application. Clove oil occasionally causes small mouth ulcers at the application site (about 5% of people in the study), so use it sparingly. Apply a small amount with a cotton swab rather than pouring it directly on your gums.
Cold Compress
If your swelling is visible from the outside or accompanied by facial puffiness, place an ice pack or cold pack on the outside of your cheek for 10 to 20 minutes at a time. Put a thin cloth between the ice and your skin. This constricts blood vessels in the area and helps reduce swelling. You can repeat every few hours as needed.
Therapeutic Mouthwash
Chlorhexidine mouthwash is the strongest antimicrobial rinse available and is often recommended for gum inflammation. A Cochrane review of 10 trials found that it significantly reduced gingivitis after four to six weeks of use compared to placebo. However, it comes with trade-offs: tooth staining is common, and many users report taste changes, oral irritation, or a burning sensation. It’s typically available by prescription or behind the pharmacy counter, depending on your location.
For everyday use, an alcohol-free antiseptic mouthwash is a gentler option that won’t irritate already-inflamed tissue. Alcohol-based mouthwashes can dry out and further aggravate swollen gums.
Adjusting Your Brushing Routine
Swollen gums are tender, and brushing with a medium or hard toothbrush can make the problem worse. Switch to a soft or extra-soft toothbrush while your gums are inflamed. Extra-soft bristles are specifically designed for people with gingivitis, periodontitis, or receding gums. Pressing too hard while brushing can actually thin gum tissue over time, so use gentle, short strokes rather than scrubbing.
Don’t stop flossing just because your gums are sore. Plaque buildup between teeth is one of the most common causes of gum swelling in the first place. If traditional floss feels too painful, a water flosser or soft interdental picks are easier on inflamed tissue.
Vitamin C
If your gums are swollen and bleed easily, low vitamin C levels could be a contributing factor. Research from Harvard Health found that low blood levels of vitamin C were associated with an increased risk of gum bleeding, and that raising intake helped resolve the problem. You don’t need megadoses. Eating more vitamin C-rich foods like bell peppers, kiwis, oranges, and kale, or taking a daily supplement of 100 to 200 milligrams, is enough to address a mild deficiency.
Pregnancy-Related Gum Swelling
Hormonal changes during pregnancy increase blood flow to the gums and make them more reactive to plaque, which is why swollen, tender gums are extremely common during pregnancy. The primary treatment is a professional dental cleaning to remove plaque buildup, combined with consistent home care: brushing twice daily, flossing once daily, and using a saltwater rinse. If symptoms are severe, your dentist may prescribe antibiotics or a medicated mouthwash, but check with your pregnancy care provider before starting any new medication.
When Home Care Isn’t Enough
If your gums have been swollen for more than a week despite consistent home care, you likely have plaque or tartar buildup that a toothbrush can’t reach. A professional deep cleaning, called scaling and root planing, removes bacteria and hardened deposits from below the gumline and along the tooth roots. This is the standard treatment for mild to moderate gum disease and is the only way to clear plaque that has migrated deep under the gums.
Some situations require urgent attention. Swollen gums accompanied by fever, rapidly increasing facial swelling, difficulty breathing or swallowing, or severe pain that keeps getting worse should be treated as a dental emergency. If the swelling is affecting your ability to breathe or swallow, go to the emergency room. Otherwise, see a dentist as soon as possible.
