Will Listerine Kill a Tooth Infection? What Dentists Say
When tooth pain strikes, it’s natural to look for fast relief. Because of that, many people wonder if Listerine can kill a tooth infection and help avoid a dental visit.
While mouthwash can reduce surface bacteria, a true tooth infection develops much deeper. For that reason, understanding this difference can help protect both your smile and your overall health.
⚠️Why Mouthwash Cannot Cure a Tooth Infection
🧩 Surface vs. Deep Infection (What Mouthwash Can’t Reach)
Cannot penetrate the tooth: Mouthwash cannot reach an infection inside the tooth.
Only works on the surface: Instead, mouthwash mainly reduces bacteria on the surface of your teeth and gums.
Does not address the cause: Most importantly, it does not treat the underlying cause of the infection.
⏳ Why Relying on Mouthwash Can Backfire
Can delay proper treatment: As a result, relying on mouthwash can delay the care you actually need.
🦷Can Listerine Kill a Tooth Infection?
No. Listerine cannot kill a tooth infection. Mouthwash may reduce bacteria on the surface of your mouth. However, it cannot reach an infection inside the tooth, root, or bone.

😌 Why Mouthwash May Seem to Help at First (Tooth Infection Symptoms)
Temporary relief does not mean the infection is gone.
Listerine can create short-term comfort because it:
Reduces surface bacteria
Contains ingredients that numb the area
Lowers minor inflammation
As a result, symptoms may feel less intense for a short time. However, the infection continues to progress beneath the surface.
❓Why You Need a Dentist for Tooth Infection Treatment
- Only a professional can diagnose: A dentist can diagnose the cause of your pain and the severity of the infection.
- Professional treatment works: A tooth infection requires professional intervention, like a root canal or an extraction.
- Risk of spreading infection: If left untreated, the infection can spread and become dangerous.
🩺 What Actually Treats a Tooth Infection (And Why Mouthwash Isn’t Enough)
Professional dental care is the only effective solution.
Treatment depends on the severity of the infection and may include:
Deep cleaning or drainage
Antibiotics when appropriate
Ultimately, addressing the cause early can often prevent more invasive procedures.
👄What Happens If a Tooth Infection Is Left Untreated?
A dental infection does not heal on its own.
Without treatment, an infection can:
Spread to the jawbone or surrounding tissues
Cause swelling, abscesses, or severe pain
In more serious cases, it may lead to medical complications.
