Getting rid of a gum infection depends on how far it has progressed. Early-stage gum disease (gingivitis) is fully reversible with improved home care and a professional cleaning. More advanced infection (periodontitis), which affects over 42% of U.S. adults 30 and older, requires deeper treatment from a dentist or periodontist because the infection has spread below the gumline into the bone and connective tissue that hold your teeth in place.
Identify What Stage You’re Dealing With
Gingivitis is inflammation limited to the gum tissue itself. Your gums may be red, puffy, and bleed when you brush or floss, but the underlying bone is still intact. Pocket depths around your teeth measure 3 millimeters or less, which is considered normal range. At this stage, no permanent damage has occurred, and the infection can be completely eliminated.
Periodontitis means the infection has moved deeper. Bacteria have worked their way into pockets between the tooth and gum, and those pockets have grown beyond 3 millimeters. Bone loss starts showing up on X-rays. In early periodontitis, pockets reach about 4 millimeters and bone loss is minor. Moderate cases involve pockets up to 5 millimeters with more significant bone loss. Severe periodontitis means pockets of 6 millimeters or deeper, with bone destruction extending well down the root. The further along it is, the more aggressive the treatment needs to be.
What You Can Do at Home
No home remedy replaces professional treatment for an established infection, but daily care is the foundation of both prevention and recovery. Brush twice a day for two full minutes, angling bristles toward the gumline at about 45 degrees so they sweep under the gum margin. Floss daily, curving the floss into a C-shape around each tooth and sliding it gently below the gumline. If traditional floss is difficult, interdental brushes or a water flosser can be equally effective at disrupting the bacterial colonies between teeth.
Saltwater rinses are a simple, low-cost way to support healing between dental visits. Mix one teaspoon of salt into eight ounces of warm water and swish for 30 seconds. The salt draws excess fluid out of swollen gum tissue and shifts the pH of your mouth toward alkaline, creating an environment where bacteria struggle to survive. This won’t cure periodontitis, but it can reduce swelling and discomfort while you’re waiting for or recovering from treatment.
A chlorhexidine mouth rinse, available by prescription, is a stronger antimicrobial option. The standard protocol is rinsing with 15 milliliters twice daily, after breakfast and before bed, for 30 seconds. Your dentist may prescribe this for a limited period after a deep cleaning or surgery to keep bacterial counts low during the critical healing window.
Professional Cleaning and Deep Cleaning
For gingivitis, a standard professional cleaning (prophylaxis) removes the hardened plaque (calcite deposits called calculus or tartar) that you can’t remove at home. Once that bacterial stronghold is gone and you maintain good brushing and flossing habits, the inflammation typically resolves within a few weeks.
For periodontitis, the standard first-line treatment is scaling and root planing, often called a “deep cleaning.” Your dental team uses instruments to scrape bacteria, calculus, and toxins from below the gumline and smooth the root surfaces so gum tissue can reattach more easily. This is usually done with local anesthesia and may be split across two or more appointments, treating one section of the mouth at a time. Many people with mild to moderate periodontitis see significant pocket depth reduction from this procedure alone, especially when paired with diligent home care afterward.
When Antibiotics Are Needed
Antibiotics aren’t used for every gum infection, but your dentist may prescribe them for aggressive or stubborn cases, particularly when deep cleaning alone hasn’t controlled the infection. The most common oral regimen combines two medications taken three times a day for seven days. For patients allergic to penicillin, a different antibiotic taken on the same schedule is typically substituted, or a three-day course of a once-daily alternative may be used instead.
In some cases, antibiotics are placed directly into the infected pocket rather than taken as pills. These localized treatments deliver a concentrated dose right where the bacteria live, minimizing side effects elsewhere in your body. Your periodontist may place these during or after a deep cleaning procedure.
Surgical Options for Advanced Cases
When pockets remain deep after scaling and root planing, or when bone loss is significant, surgery becomes the next step. The two main approaches differ considerably in recovery.
Traditional flap surgery involves lifting the gum tissue back to expose the roots and bone underneath, allowing the periodontist to thoroughly clean the area and reshape damaged bone. When the defect is the right shape, bone grafting and guided tissue regeneration can rebuild some of the lost support. The tradeoff is a longer recovery: patients commonly report more swelling, bleeding, and post-operative discomfort, along with a higher chance of gum recession and tooth sensitivity from the exposed root surfaces.
Laser-assisted treatment is a less invasive alternative for appropriate cases. Instead of cutting and lifting the gum, a laser targets infected tissue and bacteria while leaving healthy tissue intact. A second laser pass helps form a stable blood clot at the gumline that acts as a biological seal. Patients typically experience less bleeding and swelling, often need fewer or no stitches, and return to normal activities faster. That said, traditional surgery remains the more predictable choice when heavy calculus buildup is present, bone needs significant reshaping, or the defect requires precise hands-on access.
Nutrition That Supports Gum Healing
Vitamin C plays a direct role in gum health because your body needs it to produce collagen, the protein that gives gum tissue its structure and resilience. Research from Harvard Health found that low vitamin C intake is linked to increased gum bleeding. The recommended daily intake is 90 milligrams for adult men and 75 milligrams for women, but experts suggest aiming for 100 to 200 milligrams daily when you’re actively dealing with gum problems. Bell peppers, kiwis, oranges, strawberries, and kale are all rich sources. A modest supplement can fill the gap if your diet falls short.
Why Gum Infections Affect the Rest of Your Body
A gum infection isn’t just a mouth problem. Chronic periodontal inflammation sends a steady stream of inflammatory signals into your bloodstream. These molecules can impair how your body responds to insulin, making blood sugar harder to control. The same inflammatory cascade damages the lining of blood vessels, which is an early step in the development of cardiovascular disease. Bacteria from infected gums also enter the bloodstream directly, where they’ve been found contributing to the buildup of arterial plaques. There’s even evidence that the chronic immune activation from periodontitis can trigger autoimmune responses linked to rheumatoid arthritis. Treating a gum infection has benefits that extend well beyond your mouth.
Signs a Gum Infection Is an Emergency
Most gum infections progress slowly, but a dental abscess can escalate quickly. If you develop a fever along with facial swelling and can’t reach your dentist, go to an emergency room. Difficulty breathing or swallowing is especially urgent, as these symptoms suggest the infection has spread into the jaw, throat, neck, or beyond. An untreated abscess that spreads can become life-threatening, so don’t wait it out if these red flags appear.
