Inflamed gums are almost always a sign that bacteria have built up along the gumline, triggering your body’s immune response. The good news: in most cases, you can reduce the swelling at home within a few days by improving your oral hygiene routine and using a few simple remedies. If the inflammation has been building for weeks or months, though, you may need professional treatment to clear bacteria that a toothbrush can’t reach.
Start With a Saltwater Rinse
A warm saltwater rinse is one of the fastest ways to calm swollen gums. Mix 1 teaspoon of salt into 8 ounces of warm water, swish it around your mouth for 15 to 20 seconds, then spit. If your gums are very tender and the rinse stings, cut the salt to half a teaspoon for the first day or two. You can rinse several times a day, especially after meals, to keep bacteria levels down while your gums heal.
Salt draws fluid out of swollen tissue and creates an environment that’s harder for bacteria to thrive in. This won’t fix the underlying cause on its own, but it reduces pain and swelling while you address the bigger picture.
Upgrade Your Brushing and Cleaning Routine
Plaque, the sticky bacterial film that forms on teeth throughout the day, is the most common trigger for gum inflammation. When it sits along the gumline for too long, your gums respond with redness, swelling, and bleeding. The fix is mechanical: physically removing that plaque every day before it hardens into tarite that only a dentist can scrape off.
Use a soft-bristled toothbrush and angle it at about 45 degrees toward the gumline, using short, gentle strokes. Brushing too hard with a stiff brush can actually make inflamed gums worse. An electric toothbrush with a pressure sensor can help if you tend to scrub aggressively.
Cleaning between your teeth matters just as much as brushing. Research reviewed by the American Dental Association found that adding floss or interdental brushes to a brushing routine reduces both plaque and gum inflammation more than brushing alone. Interdental brushes, the small bottle-brush-shaped picks that slide between teeth, may actually be more effective than traditional floss. If you have wider gaps between your teeth, try those first. For tighter spaces, regular floss or floss picks work well. The key is doing it daily, not which tool you pick.
Common Causes Beyond Poor Hygiene
Not all gum inflammation comes from skipping floss. Hormonal shifts during pregnancy, puberty, and menstruation increase blood flow to gum tissue and make it more reactive to even small amounts of plaque. Smokers face significantly higher rates of gum disease because tobacco reduces blood flow and weakens the immune response in oral tissue.
Several types of medication can cause gum tissue to actually overgrow, a condition called gingival hyperplasia. Certain anti-seizure drugs are well-known culprits: roughly half of people taking phenytoin develop some degree of gum overgrowth. Blood pressure medications in the calcium channel blocker family can have the same effect, with one commonly prescribed version causing it in about 38% of users. Immunosuppressant drugs taken after organ transplants carry the highest variability, with reported rates ranging from 13% to 85%. If you started a new medication in the weeks before your gums became inflamed, that connection is worth raising with your prescriber.
Vitamin C and Gum Health
Vitamin C plays a direct role in maintaining the connective tissue that holds your gums together. Severe deficiency leads to scurvy, which causes bleeding gums and loosened teeth. You don’t need to reach full-blown scurvy for low vitamin C to affect your gums, though. Adults need 75 to 90 milligrams per day (add 35 mg if you smoke). A single orange or a cup of strawberries covers that easily. If your diet is low in fruits and vegetables, that could be contributing to your symptoms.
When You Need Professional Cleaning
If your gums have been inflamed for more than a couple of weeks despite good home care, the problem is likely below the surface. Bacteria and hardened tartar can settle into the pockets between your gums and teeth, where no toothbrush or floss can reach them.
Your dentist measures those pockets with a small probe during checkups. Healthy gums have pocket depths of 1 to 3 millimeters. Once pockets reach 4 millimeters or deeper, it typically signals gingivitis or the more advanced stage, periodontitis. At that point, a standard cleaning isn’t enough. A deep cleaning, called scaling and root planing, involves your dentist or hygienist going below the gumline to scrape away tartar from the tooth roots and smooth rough spots where bacteria like to cling. The procedure is done under local anesthesia and usually takes one or two visits depending on how many areas are affected. Your gums will be sore for a few days afterward but should start looking and feeling healthier within a week or two.
Deep cleaning is the standard first-line treatment for mild to moderate gum disease. Catching it at this stage often prevents the bone loss and tooth loosening that come with advanced periodontitis.
Red Flags That Need Urgent Attention
Most gum inflammation is a slow-building problem, not an emergency. But certain symptoms mean an infection has progressed to a point that requires immediate care:
- Fever or facial swelling: These suggest the infection is spreading beyond the gum tissue.
- Pus drainage or a visible abscess: A pocket of pus along the gumline or near a tooth root needs to be drained professionally.
- Severe throbbing pain: Constant, intense pain (as opposed to tenderness when brushing) points toward an abscess rather than simple gingivitis.
- Swollen lymph nodes: Tender lumps under your jaw or along your neck indicate your body is fighting a spreading infection.
- Difficulty swallowing or breathing: This requires emergency medical attention immediately. Swelling from a dental infection can narrow the airway, and this should never be monitored at home.
What to Expect as Your Gums Heal
With consistent daily care, early-stage gum inflammation (gingivitis) typically improves within one to two weeks. Your gums may bleed more at first when you start flossing regularly, which feels counterintuitive. That bleeding should decrease within a few days as the inflammation subsides. Healthy gums are pale pink, firm, and fit tightly around the teeth. If yours are dark red, puffy, or pull away from the teeth, the inflammation is still active.
Once you’ve gotten your gums back to a healthy state, maintenance is straightforward: brush twice a day, clean between your teeth once a day, and get professional cleanings on whatever schedule your dentist recommends (every six months for most people, more often if you’ve had gum disease). Gum inflammation is highly reversible in its early stages, but it will come back quickly if the habits that caused it return.
