Inflamed gums are almost always a sign of early gum disease, and the good news is that with consistent care, mild cases can fully heal in about two weeks. The key is acting quickly: removing the bacterial buildup that’s causing the inflammation, soothing the tissue while it recovers, and preventing the problem from progressing to something more serious. Here’s what to do, starting today.
Why Your Gums Are Inflamed
The most common cause is plaque, a sticky film of bacteria that builds up along the gumline when brushing and flossing fall short. Your immune system responds to that bacteria with inflammation, leading to red, swollen, tender gums that bleed easily. This stage is called gingivitis, and it’s reversible.
Left untreated, gingivitis can progress to periodontitis, a more serious form of gum disease. In periodontitis, the gums pull away from the teeth and form pockets that trap bacteria deeper below the surface. Those pockets get harder to clean on your own, and the infection can eventually break down the bone holding your teeth in place, causing them to loosen. The goal is to catch things in the gingivitis stage, before pocket formation and bone loss begin.
Plaque buildup isn’t the only trigger. Certain medications are well-known culprits. Phenytoin, a seizure medication, causes gum overgrowth in roughly half the people who take it. Blood pressure medications called calcium channel blockers can do the same, particularly nifedipine (about 38% of users) and diltiazem (about 20%). The immunosuppressant cyclosporine carries the highest variability, causing gum overgrowth in anywhere from 13% to 85% of patients. If your gum swelling started around the same time as a new medication, that connection is worth raising with your prescriber.
Nutritional gaps also play a role. Vitamin C is essential for gum tissue repair, and a significant deficiency leads to swollen, bleeding gums as one of the earliest symptoms. Adults need 75 to 90 mg daily (add 35 mg if you smoke). Citrus fruits, strawberries, sweet peppers, broccoli, and tomatoes are all strong sources.
What You Can Do at Home Right Now
The single most effective thing you can do is improve your brushing and flossing technique and stick with it consistently. The American Dental Association recommends placing your toothbrush at a 45-degree angle to the gumline and using short, gentle back-and-forth strokes on each tooth. That angle lets the bristles reach just under the gum edge where plaque hides. Brush for two full minutes, twice a day, and use a soft-bristled brush so you don’t further irritate swollen tissue.
Floss once daily, working the floss gently into the space between each tooth and curving it against the tooth surface. If your gums bleed when you floss, that’s the inflammation responding to the disruption of bacteria, not a sign you’re doing damage. The bleeding typically stops within a week or two of consistent flossing.
A salt water rinse can help reduce inflammation and draw out bacteria between brushings. Mix half a teaspoon of salt into a cup of warm water and swish it around your mouth for 30 to 60 seconds before spitting it out. You can do this two to three times a day. It’s gentle, inexpensive, and effective as a supplement to brushing and flossing.
A diluted hydrogen peroxide rinse is another option. Start with the standard 3% hydrogen peroxide sold in drugstores and mix it with an equal part of water to bring it down to 1.5%. Swish for 30 to 60 seconds, but don’t exceed 90 seconds, and don’t swallow it. This can help reduce bacterial load in the mouth, though it shouldn’t replace your regular routine.
How Long Recovery Takes
Mild gingivitis typically resolves in about two weeks of consistent, proper oral hygiene. You should notice less redness and bleeding within the first few days. If your gums are still inflamed after two to three weeks of diligent home care, the problem may have progressed beyond what brushing and flossing alone can fix, and it’s time for a professional cleaning.
When You Need Professional Treatment
If plaque has hardened into tartar (calculus), no amount of brushing will remove it. Tartar requires scaling, which your dentist or hygienist performs using specialized hand instruments or ultrasonic tools. For deeper inflammation, the standard treatment is scaling and root planing, sometimes called a deep cleaning. During this procedure, your gums are numbed with local anesthetic, tartar is removed both above and below the gumline, and the tooth roots are smoothed so gums can reattach more easily.
After a deep cleaning, your gums will likely feel tender for a few days. As the swelling goes down, you may notice your gums have receded slightly, exposing a bit more of the tooth root. Your teeth might also feel slightly loose at first, but this resolves as the gums tighten back up during healing. Your dentist may also prescribe antibiotics, either applied directly around the tooth roots or taken orally, to help clear any lingering infection.
Signs That Need Immediate Attention
Most gum inflammation is a slow-building problem, not an emergency. But certain symptoms signal an abscess or spreading infection that needs prompt care:
- Throbbing pain that radiates to other parts of your head on the same side
- Swelling that’s warm to the touch and tender, especially if it’s increasing in size
- Fever or feeling generally unwell alongside mouth pain
- A foul taste in your mouth or visible pus near the gumline
- Pain with both hot and cold foods and drinks
If swelling starts to affect your ability to breathe or see, that’s a medical emergency. An untreated abscess can spread to surrounding tissues, so don’t wait on these symptoms.
Keeping Inflammation From Coming Back
Once your gums have healed, the habits that got you there are the same ones that keep inflammation from returning. Brush twice a day at that 45-degree angle, floss daily, and get professional cleanings on whatever schedule your dentist recommends (typically every six months, or more frequently if you’ve had periodontitis).
Pay attention to your diet. Beyond vitamin C, eating a balanced mix of fruits and vegetables supports the immune response that keeps oral bacteria in check. Smoking is one of the strongest risk factors for gum disease, both because it reduces blood flow to the gums and because it masks early symptoms like bleeding, making it easier to miss the problem until it’s advanced.
If you take a medication linked to gum overgrowth, meticulous oral hygiene becomes even more important. Your dentist can work with your prescriber to evaluate alternatives if the overgrowth is severe, but in many cases, consistent plaque control is enough to minimize the side effect.
