Swollen gums usually respond well to a combination of better oral hygiene, simple home remedies, and addressing whatever triggered the inflammation in the first place. In most cases, the cause is bacterial buildup along the gumline, and the swelling is your body’s inflammatory response to that irritation. The good news: if you catch it early, gum swelling from mild gum disease is completely reversible.
Quick Relief at Home
A salt water rinse is one of the simplest ways to calm inflamed gums. Mix one teaspoon of salt into about one cup (250 ml) of warm water, swish it around your mouth for 30 seconds, and spit it out. Do this two to three times a day, ideally after meals and before bed. Salt water draws fluid out of swollen tissue and creates an environment that’s harder for bacteria to thrive in.
If your face or jaw feels puffy, hold a cold pack against the outside of your cheek for 10 to 20 minutes at a time, with a thin cloth between the ice and your skin. This constricts blood vessels near the surface and reduces swelling. You can repeat this several times a day as needed.
Over-the-counter anti-inflammatory pain relievers like ibuprofen also help. For mild gum pain, 200 to 400 mg every four to six hours is a standard dose. Ibuprofen reduces both pain and inflammation, which makes it more useful for swollen gums than acetaminophen alone.
Why Your Gums Are Swelling
The most common cause is gingivitis, the earliest stage of gum disease. Plaque, a sticky film of bacteria, builds up along and beneath the gumline. Your immune system responds with inflammation: redness, puffiness, and gums that bleed when you brush or floss. At this stage, there’s often little or no pain, which is why many people don’t realize anything is wrong until the swelling becomes obvious.
If gingivitis goes untreated, it can progress to periodontitis. That’s when plaque spreads below the gumline and triggers a chronic inflammatory response where the body starts breaking down its own gum tissue and bone. The gums pull away from the teeth, forming deep pockets that trap more bacteria. Eventually teeth can loosen or need to be removed. This progression takes time, so catching and treating swollen gums early matters enormously.
Other triggers include hormonal changes (pregnancy, menstruation, puberty), a new medication that causes gum overgrowth as a side effect, poorly fitting dental appliances, and nutritional deficiencies. If your swelling appeared suddenly and you recently started a new medication, that’s worth mentioning to your dentist or doctor.
The Role of Vitamin C
Vitamin C is essential for producing collagen, the protein that gives your gums their structure and resilience. When your body doesn’t get enough, gum tissue weakens, heals poorly, and becomes more vulnerable to inflammation and bleeding. Severe deficiency causes scurvy, which classically shows up as bleeding, swollen gums and loose teeth.
You don’t need to be severely deficient to see an effect on your gums. Research has linked even moderate vitamin C shortfalls to worse periodontal outcomes, and supplementation has been shown to improve gum conditions partly through its antioxidant activity and its role in wound healing. The recommended daily intake is 90 mg for men and 75 mg for women. A single orange or a cup of strawberries gets you there. If your diet is low in fruits and vegetables, this is one of the easier fixes to try.
Brushing and Flossing Technique
Brushing twice a day and flossing once a day is the baseline that prevents plaque from hardening into tarite (calcified deposits your toothbrush can’t remove). But technique matters as much as frequency, especially with flossing.
The American Dental Association recommends this approach: break off about 18 inches of floss and wrap most of it around one middle finger, winding the rest around the same finger on your other hand. Hold the floss taut between your thumbs and forefingers, then guide it between teeth using a gentle rubbing motion. Never snap it straight into the gums. When the floss reaches the gumline, curve it into a C shape against the tooth and gently slide it into the space between the gum and tooth. Use an up-and-down motion along the side of each tooth, and don’t skip the back side of your last molars.
If your gums bleed when you floss, that’s actually a sign of inflammation, not a reason to stop. With consistent daily flossing, the bleeding typically resolves within one to two weeks as the gum tissue heals.
Mouthwash That Actually Helps
Not all mouthwashes are created equal when it comes to gum inflammation. The two types with the strongest evidence are prescription chlorhexidine rinses and over-the-counter essential oil rinses (the most studied being Listerine Antiseptic). In a six-month comparison, the essential oil rinse reduced gingivitis development by about 36%, while chlorhexidine reduced it by about 31%. For plaque reduction, chlorhexidine performed better at roughly 50% versus 36%.
Chlorhexidine is more powerful against plaque but tends to stain teeth with prolonged use, so dentists typically prescribe it for short courses. An essential oil mouthwash used daily is a practical long-term option that meaningfully reduces both plaque and gum inflammation on top of brushing and flossing.
When You Need Professional Treatment
If your gums have been swollen for more than two weeks despite good home care, or if the swelling keeps coming back, you likely need a professional cleaning. A standard cleaning removes plaque and tartar above the gumline, but if pockets have formed between your teeth and gums, your dentist may recommend scaling and root planing, sometimes called a deep cleaning.
During this procedure, your gums are numbed with local anesthetic. Plaque and tartar are removed from both above and below the gumline, and the tooth roots are smoothed so the gum tissue can reattach more easily. Your gums may feel sore for a couple of days afterward, but once the infection clears, the swelling shrinks back. For many people, this single treatment combined with improved home care is enough to reverse the problem entirely.
Signs the Swelling Is Something More Serious
Standard gum swelling from gingivitis looks like red, puffy gums that bleed easily. It’s uncomfortable but manageable. An abscess is a different situation. There are two types to watch for:
- Tooth abscess: severe throbbing pain that radiates to the jaw or ear, swelling in the face or jaw, sensitivity to hot and cold, fever, swollen lymph nodes, and a foul taste in the mouth.
- Gum abscess: a visible bump or boil on the gum near a tooth, sharp localized pain (especially when chewing), pus draining from the area, and in advanced cases, a tooth that feels loose.
Fever is the clearest red flag. It means the infection may be spreading beyond the local area. Facial swelling that’s getting worse, difficulty swallowing, or trouble breathing all require urgent care. An abscess won’t resolve on its own, and the infection can spread to other parts of the body if left untreated.
