An infected gum can often be managed at home in its earliest stage, but most cases need professional treatment to fully resolve. What you should do depends on how far the infection has progressed: mild redness and bleeding may respond to improved home care within days, while deeper infections involving bone loss require dental procedures and sometimes antibiotics. Here’s what works at each stage and how to tell when you need more help.
What You Can Do at Home Right Now
If your gum infection is early (red, swollen, or bleeding gums without significant pain or pus), home care can make a real difference. The most effective at-home treatment is a warm saltwater rinse: dissolve 1 teaspoon of salt in 8 ounces of warm water, swish it around the affected area for 15 to 30 seconds, and spit it out. You can do this up to four times a day, plus after meals. If it stings, drop the salt down to half a teaspoon. Saltwater draws fluid out of swollen tissue and creates an environment that’s harder for bacteria to thrive in.
Beyond rinsing, step up your brushing and flossing routine. Brush twice a day with a soft-bristled toothbrush, angling the bristles toward the gumline. Floss daily, paying extra attention to the area around the infection. An over-the-counter antiseptic mouthwash can also help reduce bacterial load. These steps won’t cure a moderate or advanced infection on their own, but they’re essential alongside any professional treatment you receive.
When Home Care Isn’t Enough
If your symptoms haven’t improved within a week, or if you have persistent pain, pus, a bad taste in your mouth, or gums that are pulling away from your teeth, you need to see a dentist. At this point, bacteria have likely moved below the gumline where brushing and rinsing can’t reach them. Delaying treatment lets the infection spread deeper into the tissue and bone that hold your teeth in place.
Scaling and Root Planing: The Standard Treatment
The first-line professional treatment for a gum infection is scaling and root planing, essentially a deep cleaning that goes well below the gumline. During the scaling portion, your dentist or hygienist uses hand instruments or ultrasonic tools to scrape away plaque and hardened tartar from the tooth surfaces above and below the gums. Root planing then smooths the root surfaces, which removes embedded bacteria and gives your gums a clean surface to reattach to.
The procedure is nonsurgical and typically done under local anesthesia. For mild to moderate gum disease, this is often the only treatment needed. Your dentist may also inject antibiotics directly around the tooth roots or prescribe oral antibiotics afterward to knock out remaining bacteria.
Recovery depends on severity. Early-stage infections (gingivitis) can resolve in a few days to a week after treatment with improved oral care. Mild periodontitis, where the infection has started affecting deeper tissue, generally takes several weeks to a couple of months to heal. Advanced periodontitis with bone loss may require several months of healing, and in some cases, follow-up surgery to repair damaged tissue.
Antibiotics for Gum Infections
Not every gum infection needs antibiotics, but when it does, the most commonly prescribed options are amoxicillin or penicillin, typically taken three to four times daily for 3 to 7 days. If those don’t work, your dentist may switch to a combination antibiotic that’s more effective against resistant bacteria.
If you’re allergic to penicillin, alternatives include azithromycin (a short course starting with a higher dose on day one, then four more days at a lower dose) or clindamycin for 3 to 7 days. For stubborn infections that don’t respond to the first round, your dentist may add a second antibiotic that specifically targets the types of bacteria common in gum disease.
Antibiotics alone won’t cure a gum infection. They reduce the bacterial load, but without physically removing the tartar and plaque buildup through scaling, the infection will return. Think of antibiotics as backup, not the main treatment.
Prescription Mouthwash
Your dentist may prescribe a chlorhexidine mouthwash, particularly after a deep cleaning or gum surgery. This is stronger than anything available over the counter. The standard protocol is rinsing for 60 seconds, twice daily. It’s effective at keeping bacteria suppressed while your gums heal, but it’s not meant for long-term use since it can stain teeth and alter taste with extended use.
What Happens After Treatment
Gum disease can be treated but not completely eradicated. Once you’ve had a gum infection, you’re at higher risk of recurrence, which is why maintenance matters. Most people who’ve been treated for periodontitis need professional cleanings every 3 to 4 months, rather than the standard twice-a-year schedule. If you respond well to treatment and keep up good home care, your dentist may eventually extend that interval to every 6 to 12 months. If healing is slow, or if you smoke or have conditions like diabetes that impair healing, you may need cleanings as often as every 2 months until things stabilize.
The goal of these maintenance visits is to catch any new buildup before it triggers another infection. Between visits, consistent brushing, flossing, and saltwater rinses remain your best defense.
Signs You Need Urgent Care
Most gum infections are slow-moving and can wait for a dental appointment. But certain symptoms signal that the infection is spreading and needs immediate attention:
- Facial swelling, especially if it’s progressing toward your eye, neck, or under your jaw
- Difficulty breathing or swallowing, which can indicate the infection is compressing your airway
- Fever, particularly combined with swollen neck glands
- Severe pain that keeps you awake and doesn’t respond to over-the-counter painkillers
- Difficulty opening or closing your mouth
Facial swelling with breathing difficulty is a medical emergency. Go to an emergency room, not a dental office. A dental infection that reaches the bloodstream can become life-threatening, and while this is uncommon, the warning signs above are the ones to take seriously.
