Swollen gums usually respond well to a combination of home care and improved oral hygiene, and in most cases you can start reducing the inflammation within a day or two. The most effective immediate steps are saltwater rinses, cold compresses, and over-the-counter anti-inflammatory medication. If the swelling is mild and limited to a small area, home treatment is often enough. But persistent or worsening swelling signals a problem that needs professional attention.
Start With a Saltwater Rinse
A warm saltwater rinse is one of the simplest and most effective first steps. Mix 1 teaspoon of salt into 8 ounces of warm water, swish it around your mouth for 30 seconds, and spit it out. If your gums are very tender and the rinse stings, cut the salt to half a teaspoon for the first day or two. Three to four rinses per week is a good maintenance frequency, but when your gums are actively swollen, you can rinse two to three times a day until the inflammation calms down.
Salt draws fluid out of inflamed tissue, which reduces swelling. It also creates an environment that’s less hospitable to the bacteria driving the irritation.
Use a Cold Compress for Pain and Swelling
If you can see or feel puffiness on the outside of your cheek or jaw, hold an ice pack or cold compress against the area for 10 to 20 minutes at a time with a thin cloth between the ice and your skin. Cold narrows the blood vessels in the area, which limits swelling and numbs pain. You can repeat this several times throughout the day with breaks in between.
Choose the Right Pain Reliever
Not all over-the-counter painkillers work the same way for gum inflammation. Ibuprofen is generally the better choice because it reduces inflammation directly at the site, not just the sensation of pain. The American Dental Association recommends NSAIDs like ibuprofen as first-line therapy for dental pain. A standard dose of 200 to 400 mg every four to six hours handles mild gum pain for most adults.
Acetaminophen works differently. It blocks pain signals in the brain rather than reducing inflammation locally. On its own, it’s less effective for swollen gums. But combining the two is surprisingly powerful. A review covering data from over 58,000 dental patients found that 400 mg of ibuprofen combined with 1,000 mg of acetaminophen was more effective than any opioid-containing pain regimen, with fewer side effects. There’s even an FDA-approved over-the-counter combination tablet (250 mg ibuprofen plus 500 mg acetaminophen per dose) designed for this kind of use.
Fix Your Brushing Technique
Swollen gums are often a sign that plaque is building up along the gum line, and the way you brush matters more than most people realize. The technique recommended by the American Dental Association, called the Bass technique, targets exactly the area where plaque causes the most damage. Place your toothbrush bristles at a 45-degree angle to the gum line and use short, gentle back-and-forth strokes. Then sweep the brush away from the gum toward the edge of the tooth. This gets bristles slightly under the gum margin where bacteria accumulate.
Brush twice a day and floss once. If you’ve been skipping flossing, your gums will likely bleed the first few times you start again. That’s normal. The bleeding typically decreases within a week or two as the inflammation subsides.
Why Gums Swell in the First Place
The most common cause is plaque, the sticky film of bacteria that forms on teeth throughout the day. When plaque sits along the gum line for too long, the bacteria trigger your immune system to mount an inflammatory response. Your body sends extra blood flow to the area, releases chemical signals that recruit immune cells, and the tissue swells as a result. Left unchecked, this cycle intensifies: the immune response itself starts damaging the surrounding tissue, creating an environment that makes the inflammation worse rather than better.
In its earliest stage, this is gingivitis. The gums turn red, swell, and bleed easily, but there’s usually little or no pain. Gingivitis is fully reversible with good oral care. If it progresses, though, the gums begin pulling away from the teeth and forming pockets that trap more bacteria. The inflammation starts breaking down bone. This is periodontitis, and the damage at this stage can’t be fully reversed, only managed.
Hormonal and Nutritional Causes
Pregnancy is a well-known trigger for gum swelling. Rising levels of estrogen and progesterone increase blood flow to the gums, making them more prone to inflammation, soreness, and bleeding, even with good oral hygiene. If you’re pregnant and dealing with swollen gums, brush twice daily, floss once daily, rinse with warm saltwater, and use alcohol-free mouthwash. Avoid sugary foods and drinks, and schedule a dental visit during pregnancy. Some medications used to treat gum problems aren’t safe during pregnancy, so check with your pregnancy care provider before starting anything new.
Vitamin C deficiency can also cause gum swelling. Severe deficiency leads to scurvy, which causes gums to become swollen, bleeding, purple, and spongy. Most adults need 75 to 90 mg of vitamin C daily (smokers should add 35 mg to that number). You don’t need mega-doses. A single orange or cup of strawberries easily covers it.
When Home Care Isn’t Enough
If your gums are still swollen after a week or two of consistent home care, or if the swelling is getting worse, you likely need a professional cleaning that goes deeper than what a toothbrush can reach. The standard treatment is called scaling and root planing. Your dentist or hygienist numbs your gums with a local anesthetic, then uses hand instruments or ultrasonic tools to remove plaque and tartar from both above and below the gum line. They also smooth the root surfaces of your teeth so bacteria have a harder time reattaching.
The procedure takes one to two hours. Most people return to normal activities the same day. Your gums may feel sore for a couple of days afterward, but you won’t need stitches, and you can eat and drink whatever is comfortable. The goal is to reset the health of your gums so they can reattach more closely to the teeth and the pockets where bacteria were hiding can shrink.
Signs That Need Immediate Attention
Most gum swelling is uncomfortable but not dangerous. There are a few situations, however, where swelling signals something more serious, like a dental abscess that’s spreading. Go to an emergency room if you notice any of the following:
- Difficulty breathing, speaking, or swallowing
- A swollen or painful eye, or sudden vision changes
- Severe swelling inside the mouth
- Difficulty opening your mouth
These can indicate that an infection is spreading into deeper tissues of the head and neck, which requires urgent treatment. A localized gum abscess that stays small and doesn’t produce these symptoms still needs dental care, but it’s not an emergency room situation.
