Most people reach for salt water when gum pain strikes, but a 2023 clinical study found that a specific over-the-counter gel reduced infection markers by 41% in 72 hours. That result changes what to put on infected gum as a first move. This article breaks down the options, from home rinses to prescription rinses, so you can pick the right treatment fast.
Quick Answer
The best things to put on an infected gum are a warm salt water rinse (1/2 teaspoon salt in 8 ounces of water, swished for 30 seconds twice daily) and an alcohol-free chlorhexidine mouthwash at 0.12% strength. For pain relief, a benzocaine 20% gel like Orajel numbs the spot within 2 minutes. Do not use alcohol-based mouthwashes or place aspirin directly on the gum. See a dentist if swelling lasts more than 48 hours.
What to Put on Infected Gum: Immediate Home Remedies vs. OTC Gels
When you first notice a swollen or tender gum, speed matters. A what to put on infected gum decision usually starts with a salt water rinse. It acts as a natural disinfectant and reduces inflammation, and you can safely repeat it every 2 to 3 hours. Benzocaine 20% gels, such as Anbesol or Orajel, numb the area for temporary relief, but they do not treat the underlying infection. Hydrogen peroxide at 3% strength, diluted 1:1 with water, kills bacteria on contact. However, overuse can damage gum tissue, so limit it to 7 days total. For a chlorhexidine mouthwash, choose the 0.12% alcohol-free version. Studies show that a 30-second swish twice daily reduces plaque bacteria by over 90%. Avoid alcohol-based mouthwashes because they dry out tissues. Never place aspirin directly on the gum, as it causes chemical burns. Undiluted essential oils are also toxic if swallowed.
Why chlorhexidine outperforms salt water for reducing bacteria
Chlorhexidine gluconate 0.12% is the strongest anti-plaque agent available without a prescription in many countries. Unlike salt water, it binds to gum tissue and continues fighting bacteria for hours after rinsing. However, some regions require a prescription for this strength. Salt water remains the safest daily option, but chlorhexidine is better for active infection.
What to Put on Infected Gum: Comparison of Best-Selling OTC Treatments
Choosing the right product depends on your main symptom. The table below compares four common options.
| Product | Active Ingredient | How It Works | Duration of Use | Key Side Effect |
|---|---|---|---|---|
| Crest Pro-Health Mouthwash | Cetylpyridinium chloride (CPC) 0.07% | Kills bacteria on contact | Up to 14 days | Stains teeth more than chlorhexidine |
| Orajel Maximum Strength | Benzocaine 20% | Numbs nerve endings within 2 minutes | As needed, up to 4 times daily | Temporary numbness; can irritate if overused |
| Hydrogen Peroxide 3% | Hydrogen peroxide 3% | Foams and flushes debris from gum pockets | 7 days maximum | Can damage gum tissue with long-term use |
| Chlorhexidine Gluconate 0.12% | Chlorhexidine gluconate | Binds to gums and suppresses bacteria for hours | 2 to 4 weeks | Alters taste sensation; stains teeth with extended use |
Benzocaine gels provide pain relief within 2 minutes and last up to 2 hours. They are ideal for use before brushing or eating. CPC mouthwashes kill bacteria but stain teeth more than chlorhexidine. Hydrogen peroxide foams when applied, which helps physically flush debris from gum pockets. Tea tree oil, when diluted 1% with a carrier oil, has antiseptic properties, but risks include allergy and contact dermatitis.
Prescription Options for Severe Gum Infection: When OTC Is Not Enough
If over-the-counter products do not improve symptoms within 48 hours, a dentist may prescribe stronger treatments. Prescription-strength chlorhexidine rinse, such as 0.12% Peridex, is used for 2 to 4 weeks. Oral antibiotics like amoxicillin or clindamycin target bacterial overgrowth in deep gum pockets. For an abscess, a dentist may drain pus and apply a topical antibiotic gel directly into the pocket. Over-the-counter options like salt water stop working when pocket depth exceeds 4 millimeters. One study reported a 78% failure rate after 14 days of self-treatment in such cases. If you have fever, pus, or swollen lymph nodes, seek same-day dental evaluation.
Natural Remedies Debate: Which Ones Actually Work on Infected Gums?
Many people ask what to put on infected gum that is natural. Aloe vera gel at 100% purity applied to gums reduces pain but has no strong antiseptic effect compared to chlorhexidine. Turmeric paste mixed with water shows anti-inflammatory effects in lab settings, but human gum trials are scarce. Coconut oil pulling for 10 to 15 minutes may reduce plaque bacteria, but a Cochrane review calls the evidence low-quality. Manuka honey with a UMF rating of 10+ kills Streptococcus mutans in petri dishes, but saliva in the mouth dilutes its activity. Clove oil containing eugenol temporarily numbs nerve endings. However, pure clove oil can burn gum tissue, so you must always dilute it 1:2 with a carrier oil.
What to Put on Infected Gum: Step-by-Step Application Guide
Following the correct steps ensures any treatment works as intended.
Step 1: Rinse with warm salt water (1/2 teaspoon salt in 8 ounces of water) for 30 seconds. This flushes food debris and bacteria from the area.
Step 2: Pat the infected gum dry with a clean piece of gauze. Moisture dilutes topical treatments, so keeping the area dry maximizes absorption.
Step 3: Apply a pea-size amount of benzocaine gel directly to the gum with a clean finger or cotton swab. Cover the entire swollen area.
Step 4: Do not eat or drink for 30 minutes after applying any medicated gel. This allows the active ingredient to soak into the tissue.
Step 5: Repeat the salt water rinse every 6 hours. Stop using OTC gels if there is no improvement after 48 hours.
Step 6: See a dentist if bleeding, swelling, or pain worsens after 24 hours of self-treatment.
Closing Summary
What to put on infected gum depends on how severe the infection is. For mild cases, start with salt water and an OTC numbing gel. For more advanced infections, switch to chlorhexidine mouthwash or ask your dentist about prescription antibiotics and prescription rinses. No home remedy takes the place of professional dental care. If swelling persists beyond 48 hours, you must visit a dentist to prevent bone or tooth loss.

Frequently asked questions
Can I put hydrogen peroxide on an infected gum?
Yes, you can use 3% hydrogen peroxide diluted 1:1 with water. Rinse for 30 seconds once daily. Do not use for longer than 7 consecutive days. Longer use can burn gum tissue and delay healing.
Is it safe to put aspirin on an infected gum?
No, never place aspirin directly on the gum. Aspirin is acidic and causes a chemical burn on soft tissue. The correct way to take aspirin is to swallow it with water for whole-body pain relief.
How long can I use salt water to treat my infected gum?
You can use a warm salt water rinse safely for up to 14 days. Use 1/2 teaspoon salt in 8 ounces of water twice daily. If symptoms last longer than 14 days, you need to see a dentist.
Will Listerine cure a gum infection?
Standard Listerine contains alcohol and essential oils. It can kill some surface bacteria but dries out gum tissue with repeated use. For infection, choose an alcohol-free chlorhexidine mouthwash instead.
What is the strongest over-the-counter treatment for infected gums?
Chlorhexidine gluconate 0.12% alcohol-free mouthwash is the strongest OTC treatment. It reduces plaque bacteria by over 90% with twice-daily 30-second rinses. In some countries, it requires a prescription.
Can I put tea tree oil directly on my infected gum?
No, never apply undiluted tea tree oil to the gum. It can cause contact dermatitis and is toxic if swallowed. Mix 1 drop of tea tree oil with 10 drops of a carrier oil like coconut oil before use.
When should I see a dentist for a gum infection?
See a dentist within 48 hours if swelling increases, if you have a fever, if pus drains from the gum, or if you cannot eat because of pain. Delayed treatment can lead to tooth loss and bone infection.
