Swollen gums usually respond well to a combination of home remedies and over-the-counter options. A warm saltwater rinse is the simplest first step, and anti-inflammatory pain relievers like ibuprofen can reduce both the swelling and the discomfort. What you take depends on the cause, though, so it helps to understand your options and when the swelling signals something that needs professional treatment.
Saltwater and Other Rinses
A saltwater rinse is the cheapest, fastest thing you can do for swollen gums. It draws fluid out of inflamed tissue, reduces bacteria, and promotes healing. Mix 1 teaspoon of table salt into 4 cups of warm water. Adding 1 teaspoon of baking soda to the same solution creates an alkaline environment that further discourages bacterial growth. Swish gently for 30 seconds and spit. You can repeat this several times a day.
Hydrogen peroxide is another effective rinse for short-term use. Mix two parts water with one part standard 3% hydrogen peroxide (the kind sold at drugstores). Swish for 30 seconds and spit it out completely. Don’t use anything stronger than 3%, and don’t swallow. This kills surface bacteria and can help with minor gum infections, but it’s not meant for daily long-term use since it can irritate tissue over time.
Over-the-Counter Pain Relievers
Ibuprofen is the best first choice for swollen gums because it does double duty: it relieves pain and actively reduces inflammation. You can take 200 to 400 mg every 6 to 8 hours as needed. Don’t exceed 1,200 mg in a day without medical guidance. Because it targets the inflammatory process itself, ibuprofen can noticeably shrink swollen tissue within a few hours.
Acetaminophen helps with pain but does not reduce swelling. If you can’t take ibuprofen (due to stomach issues, blood thinners, or kidney concerns), acetaminophen is a reasonable alternative for comfort. Stay under 4,000 mg total in 24 hours to avoid liver strain. Combination tablets containing both ibuprofen and acetaminophen are also available, typically dosed at 2 tablets every 8 hours with a maximum of 6 tablets per day.
Topical Numbing Gels
Benzocaine gels (sold as Orajel and similar brands) numb the gum surface on contact and can make eating or brushing less painful. Apply a small amount directly to the swollen area up to 4 times a day. These gels don’t treat the underlying cause, but they provide fast, localized relief when the swelling makes your gums too tender to touch. Do not use benzocaine products on children under 2 years old.
Prescription Mouthwash
If your swollen gums are caused by gingivitis, your dentist may prescribe a chlorhexidine mouthwash. This is an antiseptic rinse that kills the bacteria responsible for gum disease more effectively than anything available over the counter. The standard dose is 15 mL swished for 30 seconds, twice a day. Chlorhexidine can stain teeth with prolonged use, so it’s typically prescribed for a limited period. It’s worth the tradeoff when your gums are actively inflamed and need help getting bacterial levels under control.
Vitamin C for Chronic Gum Problems
If your gums swell or bleed repeatedly, low vitamin C intake could be a contributing factor. Vitamin C is essential for collagen production, and collagen is the structural protein that holds your gum tissue together. Severe deficiency causes scurvy, which includes significant gum bleeding and swelling, but even mildly low levels can weaken gum tissue. The recommended daily intake for adult men is 90 mg; women need 75 mg. Harvard Health suggests aiming for 100 to 200 mg daily through foods like oranges, bell peppers, kiwis, and kale, or through a supplement if your diet falls short.
When You Need Antibiotics
Swollen gums caused by a bacterial infection, particularly a gum abscess, often require prescription antibiotics. Your dentist or doctor will typically prescribe a course lasting 3 to 7 days. If the infection doesn’t respond to the first antibiotic, stronger alternatives are available. You can’t get antibiotics over the counter, and they’re not appropriate for every case of gum swelling. They’re reserved for active infections where bacteria have spread into the tissue or formed an abscess.
Signs that an infection is driving your swollen gums include pus draining from the gumline, a persistent foul taste in your mouth, or pain that throbs even when you’re not eating.
Deep Cleaning for Persistent Swelling
When gum swelling keeps coming back or doesn’t resolve with home care, the cause is often tartar buildup below the gumline that no amount of brushing can reach. A procedure called scaling and root planing addresses this directly. Your dentist or hygienist removes plaque and tartar from above and below the gumline, then smooths the tooth root surfaces so bacteria have fewer places to attach.
The procedure sounds intensive, but most people return to normal activities the same day. Your gums may feel sore for a couple of days afterward, and some tooth sensitivity is common but typically fades within a month or two. For many people with chronic gum swelling caused by early periodontal disease, this single procedure combined with improved home care is enough to resolve the problem.
Red Flags That Need Immediate Attention
Most gum swelling is manageable at home, at least temporarily. But certain symptoms mean the problem has escalated beyond what rinses and ibuprofen can handle. Swelling that spreads from your gums to your jaw or face, especially with a fever, may indicate a spreading infection. Severe pain combined with visible pus and facial swelling points to a dental abscess that needs urgent drainage.
If you have difficulty breathing, trouble swallowing, or significant swelling in your face or neck, go to an emergency room. These are signs that an infection may be compromising your airway, which is a genuine medical emergency rather than a dental issue you can schedule around.
