How Do You Get Rid of Infection in Your Gums?

Getting rid of a gum infection starts with physically removing the bacterial buildup that caused it, either through professional dental cleaning or improved daily oral hygiene, and sometimes both combined with medication. The specific treatment depends on how far the infection has progressed. Mild gum inflammation (gingivitis) can often be reversed with better brushing and flossing habits alone, while deeper infection that has reached the bone (periodontitis) typically requires hands-on treatment from a dentist or periodontist. The encouraging part is that even moderate-to-advanced gum disease responds well to a combination of mechanical cleaning and targeted antimicrobial therapy.

What Is Actually Happening Inside Infected Gums

A gum infection is not caused by a single “bad” germ. It begins when the natural community of bacteria in your mouth shifts out of balance. Research tracking this shift found that as gum disease progresses from early inflammation to bone-damaging periodontitis, the mix of bacterial species changes dramatically: populations of normally dominant bacteria like Streptococcus collapse, while other species surge in number and diversity increases overall.¹ This shift matters because the immune system responds to these new bacterial populations by releasing inflammatory molecules that, over time, break down the tissue and bone supporting your teeth.² In other words, the bone loss in periodontitis is partly caused by your own immune response fighting the infection, not just the bacteria themselves.

This is why treating gum infection is not as simple as killing bacteria with a pill. You have to physically disrupt and remove the bacterial colonies (called biofilm) that cling to tooth surfaces below the gumline, then give the immune system a chance to calm down and let tissues heal. Every treatment described below targets one or both of those goals.

Professional Cleaning Is the Foundation

The first-line professional treatment for gum infection is scaling and root planing, sometimes called a “deep cleaning.” A dental hygienist or periodontist uses instruments (hand-held or ultrasonic) to scrape hardened deposits off tooth roots and smooth the root surfaces so bacteria have less to cling to. This sounds basic, but it works. A meta-analysis of the evidence found that scaling and root planing produced about a 1 mm reduction in pocket depth for moderately deep pockets and roughly 2 mm for deep pockets, with measurable gains in tissue reattachment at both levels.³ Those numbers might sound small, but pocket depth is measured in millimeters, and shaving off one or two of them can mean the difference between a pocket that traps bacteria and one that you can keep clean on your own.

For most people with gum disease, this mechanical cleaning is the single most important step. The evidence consistently shows that it is adequate to resolve the clinical condition in most cases without any additional drugs.⁴ Additional therapies come into play when specific areas do not respond to cleaning alone or when the disease is aggressive.

What You Can Do at Home

Professional treatment sets you up for healing, but what you do between dental visits determines whether the infection stays away. The goal of daily home care is simple: remove enough bacterial plaque from tooth surfaces and the gumline that inflammation cannot take hold again.

Brushing is the obvious starting point, but technique and duration matter more than the type of brush you use. A randomized trial comparing manual and electric toothbrushes found that a full two minutes of manual brushing significantly outperformed shorter brushing times and some automatic brush designs at removing plaque.⁵ If you use an electric brush, aim for two minutes and make sure the bristles reach the gumline. A quick once-over is not enough.

Interdental cleaning, meaning floss, interdental brushes, or water flossers, is where many people fall short. Bacteria love the tight spaces between teeth, and your toothbrush bristles simply cannot reach there. A clinical trial found that adding an interdental flosser to regular brushing was significantly more effective at reducing plaque than brushing alone.⁶ The specific tool matters less than consistent daily use. If you hate string floss, try small interdental brushes or a water flosser. The best device is the one you will actually use every day.

Antiseptic Mouthwashes and Their Trade-Offs

Chlorhexidine mouthwash is the most studied antimicrobial rinse for gum disease. A systematic review found that chlorhexidine rinses reduced plaque by about a third and gingivitis by about a quarter compared to placebo.⁷ Those are meaningful reductions, but chlorhexidine comes with well-documented downsides: tooth staining, increased calculus (tarite) formation, taste disturbance, and occasionally sore spots on the inside of the mouth.⁸ The staining is cosmetic, not harmful, but it bothers many people enough that they stop using the rinse.

Chlorhexidine rinses also promote calculus buildup on surfaces where plaque is present, with one trial finding calculus on more than a quarter of test surfaces after regular use, compared to under 5% on control surfaces.⁹ This is why dentists typically prescribe chlorhexidine for short-term use after procedures rather than as a permanent daily rinse. Over-the-counter rinses with cetylpyridinium chloride or essential oils (like Listerine) have weaker evidence behind them but also cause fewer side effects, making them a more practical long-term option for some people.

When Antibiotics Are Needed

Antibiotics are not a first-choice treatment for gum infection. They work best as an add-on to mechanical cleaning, not a replacement for it. When used alongside scaling and root planing, systemic antibiotics provide additional benefit in reducing pocket depth and preventing further attachment loss.¹⁰ But given the risks of antibiotic resistance and side effects, their use should be reserved for specific situations.

The clearest cases for systemic antibiotics include aggressive forms of periodontitis, gum disease that does not improve after thorough mechanical cleaning, and patients with systemic conditions that weaken their immune defenses.⁴ The most commonly prescribed combination is amoxicillin plus metronidazole, which has shown effectiveness in various stages of periodontitis.¹¹

Locally delivered antibiotics are an alternative that avoids most of the body-wide side effects. These are gels, chips, or fibers placed directly into the infected pocket by a dentist. Evidence supports their use as add-ons to scaling and root planing, particularly for individual pockets that are not responding to mechanical cleaning alone.¹² One widely studied local option is the chlorhexidine chip, which showed measurable reductions in pocket depth and gum inflammation compared to other antimicrobials after one and three months.¹³

A Different Kind of Drug Approach

There is an interesting twist in the pharmacology of gum disease. Low-dose doxycycline, a tetracycline antibiotic, has properties unrelated to killing bacteria: at sub-antibiotic doses, it can tamp down the body’s own tissue-destroying enzymes, which are a major driver of the damage in periodontitis.¹⁴ This strategy, known as host-modulation therapy, arose from the discovery that tetracycline’s ability to slow periodontal breakdown comes largely from inhibiting enzymes called matrix metalloproteinases rather than from its antimicrobial action.¹⁵ Because the dose is too low to affect bacteria, it does not contribute to antibiotic resistance. It is a niche treatment, but a useful one when tissue destruction continues despite good plaque control.

Surgery for Advanced Cases

When gum pockets remain deep after non-surgical treatment, surgery becomes an option. The goals vary depending on the situation: sometimes the aim is to reduce pocket depth so the area becomes cleanable again, and sometimes it is to rebuild bone that has already been lost.

Flap surgery involves lifting the gum tissue away from the bone, cleaning out deep deposits of bacteria and damaged tissue, and repositioning the gum closer to the bone to eliminate or reduce pockets. For intrabony defects, where infection has eaten a vertical hole into the bone around a tooth, regenerative procedures try to coax the bone back. A systematic review from the American Academy of Periodontology found that biologic agents and bone grafts performed comparably to each other, and both outperformed simple flap surgery in restoring bone and attachment in these defects.¹⁶

Surgery sounds intimidating, but it is often the most direct path to saving teeth that would otherwise be lost to progressive bone destruction. Not everyone with gum disease needs it; it is typically reserved for cases where non-surgical treatment has been tried and pockets remain problematic.

Laser Therapy and Photodynamic Treatment

Dental lasers have gained attention as an alternative or supplement to traditional scaling. They can kill bacteria and detoxify root surfaces, with a particular advantage in reaching areas that conventional instruments struggle to access.¹⁷ Antimicrobial photodynamic therapy, which uses a light-sensitive dye activated by a specific wavelength of light to kill bacteria, has also shown promise. One randomized trial found that photodynamic therapy and deep scaling both suppressed key periodontal bacteria more effectively than diode laser alone, and both resulted in fewer persistent deep pockets after six months.¹⁸

Preliminary research in patients with both periodontitis and type 2 diabetes found that adding photodynamic therapy or probiotics to conventional treatment improved pocket bleeding and pocket depth compared to standard treatment alone.¹⁹ This remains an area of active research, and most guidelines still treat laser and photodynamic therapies as adjuncts to mechanical cleaning rather than replacements for it.

Do Home Remedies Like Oil Pulling Work?

Oil pulling, the practice of swishing oil (usually coconut or sesame) in the mouth for 10 to 20 minutes, has roots in traditional Ayurvedic medicine and has attracted attention as a “natural” approach to oral health. A review of the tradition noted its potential as a supplement to conventional plaque control, particularly in communities with limited access to dental products.²⁰ When researchers compared coconut oil pulling head-to-head with chlorhexidine, one study found no significant difference in gum inflammation scores between the two after 14 days.²¹

That sounds impressive, but the evidence is thin. Most oil pulling studies are small, short-term, and compare the practice only against doing nothing or against chlorhexidine rinses. Nobody has tested oil pulling as a treatment for established periodontitis with deep pockets and bone loss. If you find oil pulling pleasant and want to add it to your routine, it probably will not hurt, but it should not replace brushing, flossing, or professional treatment. Thinking of it as a complementary practice rather than a cure is the honest framing.

Smoking, Vaping, and Recovery

Smoking is one of the strongest modifiable risk factors for gum disease, and it also undermines treatment. If you smoke and are trying to get rid of a gum infection, quitting will improve your odds of recovery more than almost any other single change you can make.

Vaping has often been marketed as a safer alternative, but the evidence is not reassuring when it comes to gum health. A review of the clinical literature found ample evidence connecting vaping to increased risk of gingivitis and periodontal disease.²² A meta-analysis confirmed the pattern: e-cigarette users carry greater risk of periodontal disease than nonsmokers, though lower risk than conventional cigarette smokers.²³ In practical terms, a prospective study comparing treatment outcomes found that after full-mouth ultrasonic scaling, gum inflammation was worse in cigarette smokers than in people who vaped, who in turn fared worse than nonsmokers.²⁴ Switching from smoking to vaping may slightly improve your gum treatment outcomes, but going nicotine-free gives you the best chance.

How Often Do You Need Follow-Up?

Once you have been treated for gum disease, ongoing maintenance cleanings are essential to keep the infection from returning. Many dental offices default to scheduling these every three months, but the evidence for that specific interval is surprisingly weak. A systematic review looking for support of a fixed recall period found insufficient evidence to recommend any single interval for all patients.²⁵ A Cochrane review similarly found no randomized trials comparing different maintenance intervals or different approaches to supportive care.²⁶

What this means practically is that your maintenance schedule should be individualized. Someone with aggressive disease, deep residual pockets, or diabetes might need visits every two to three months, while someone who responded well to initial treatment and has excellent home care might be fine at four- to six-month intervals. The key is that your dentist or periodontist reassesses your gum measurements at each visit and adjusts accordingly rather than running on autopilot.

The Role of Genetics

If you have done everything right and still struggle with recurring gum infections, your genes may be part of the picture. A meta-analysis of over 70,000 participants found that variations in several genes involved in inflammation were significantly associated with the risk of developing chronic periodontitis.²⁷ Earlier research identified specific gene variants that correlated with a two- to fourfold increase in the production of key inflammatory molecules, placing carriers at higher risk for severe disease.²⁸

Genetic risk does not mean gum disease is inevitable. It means some people’s immune systems are primed to overreact to bacterial buildup, so they need more aggressive plaque control and possibly shorter intervals between professional cleanings. If you have a family history of tooth loss from gum disease, mention it to your dentist. It can help them calibrate how closely to monitor you.

When a Gum Infection Is an Emergency

Most gum infections develop slowly over months or years, but there is an acute form called necrotizing ulcerative gingivitis that needs immediate attention. It typically strikes fast, with painful, bleeding gums, destruction of the tissue between the teeth, bad breath, and sometimes fever and swollen lymph nodes.²⁹ It is strongly associated with stress, poor nutrition, smoking, and compromised immune systems.

Treatment for this condition is staged: the first priority is stopping the tissue destruction and controlling pain, usually with gentle debridement and sometimes antibiotics. Once the acute phase is under control, the underlying chronic gum condition is addressed. Craters left in the gum tissue after healing may eventually need surgical correction. If you develop sudden, severe gum pain with a foul taste, do not wait for a routine appointment. Call your dentist or visit an emergency dental clinic.

Gum Disease and the Rest of Your Body

Gum infections do not stay confined to your mouth. The bacteria and inflammatory molecules involved in periodontitis can enter the bloodstream and affect distant organs. Research has established plausible biological pathways linking periodontal infections to the development of atherosclerosis, the buildup of plaque in arteries.³⁰

The connection to diabetes runs in both directions. People with diabetes are more prone to gum disease, and research suggests that intensively treating gum disease can help lower blood glucose levels in people with type 2 diabetes.³¹ This bidirectional relationship means that if you have diabetes, treating your gum infection is not just about saving your teeth. It may also contribute to better blood sugar management. Conversely, getting your diabetes under better control will help your gums heal after treatment.
