Can Listerine Mouthwash Kill HPV?
Listerine is an antiseptic mouthwash popular for fighting bad breath and gingivitis. But can regularly gargling with Listerine also kill or reduce contagious viruses like human papillomavirus (HPV) that thrive in the oral cavity?
HPV is primarily spread through sexual contact, but mouth-to-mouth transmission is also possible. The virus can survive in the mouth and throat, potentially leading to health issues like oral cancers down the line.
Understanding how HPV infects the body, the role of oral hygiene, and Listerine's effectiveness can help you make informed choices about protecting your health.
How HPV Spreads to the Mouth and Throat
Certain strains of HPV are mainly sexually transmitted through contact with infected skin, fluids, or mucous membranes. But the virus can also spread through open-mouth kissing and oral sex.
Once contracted orally, HPV embeds itself in the mucous membranes of the mouth and throat. It can then be passed via saliva or close skin contact to future partners.
Oral HPV tends to infect the following areas:
Tonsils and Throat
The soft tissue at the back of the throat, including the tonsils, is vulnerable due to its porous, absorbent surface.
Base of the Tongue
The irregular surfaces near the tongue are breeding grounds where the virus thrives.
Soft Palate and Uvula
The soft fleshy areas at the roof of the mouth provide an environment for HPV to set in.
Gums and Inner Cheeks
The moist mucous membranes along the gums and inner cheeks allow HPV contact and transmission.
Good oral hygiene may help reduce viral load in the mouth and spread to partners. But can a mouthwash like Listerine effectively kill infection-causing HPV?
How Listerine May Combat Oral HPV
Listerine relies on antiseptic formulas to reduce bacteria in the mouth that contribute to plaque buildup and gingivitis. Manufacturers also claim it has antiviral activity.
Two of Listerine's active ingredients - menthol and thymol - disrupt the lipid outer envelopes of certain viruses. This damage may potentially:
Inactivate Viruses
The antiseptic agents can weaken viruses like HPV and interrupt their ability to infect cells in the mouth and throat.
Reduce Viral Load
Lowering levels of active virus in the oral cavity may help decrease transmission risk.
Prevent Replication
Disrupting the virus’s lipid envelope prevents it from replicating and spreading infection.
However, current research specifically on Listerine's effects on oral HPV in humans is very limited. So far, studies have only been done in vitro in lab settings, not real-world conditions.
Preliminary Research on Listerine and HPV
Early small-scale studies found some promising results on Listerine's effects against oral HPV, but had limitations:
Reduced Viral Load in Culture
One lab study showed up to 92% reduction of detectable HPV in cultured human keratinocytes after one minute exposure to Listerine.
Prevented Reinfection of Cells
Another in vitro study found Listerine could prevent reinfection of human cells with HPV after 2 minutes of contact.
Quick Inactivation
Tests showed four Listerine products inactivated over 99% of HPV in culture within 30 seconds.
While encouraging, these preliminary studies were all done on cell samples in labs. Clinical trials still need to be done on actual HPV patients using Listerine daily.
Limitations of Listerine Against HPV
Despite early lab results, there are some key limitations to relying solely on Listerine or any mouthwash to kill HPV:
No Clinical Trials
To date, no clinical trials have researched regular Listerine use on oral HPV infections in humans. Its real-world effects require further study through rigorous controlled experiments.
Difficult to Reach All Areas
Gargling may not reach or treat all areas vulnerable to HPV, like deep in the tonsils, base of the tongue, throat, etc. These can still harbor the virus.
Doesn’t Treat Existing Infection
Listerine can only help prevent spread but cannot cure or resolve an existing HPV infection. The virus remains in the body over time.
Not a Replacement for Screening
Using mouthwash does not eliminate the need for regular oral cancer screenings to catch HPV-related abnormalities early.
Based on current evidence, Listerine may help reduce oral HPV transmission risk, but cannot treat or definitively kill existing infections.
Daily Oral Hygiene Habits to Help Combat HPV
While more research on Listerine is still needed, adopting diligent daily oral hygiene habits provides your best defense against HPV. Recommendations include:
See Your Dentist Regularly
Get a professional dental exam and cleaning every 6 months to closely monitor for any oral changes or abnormalities.
Brush Twice Daily
Gently brush your teeth, gums, tongue and roof/inside of mouth thoroughly morning and night.
Floss Once a Day
Use floss to deeply clean between teeth and reach inner gum lines where viruses can settle.
Use Mouthwash Daily
Gargle an antiseptic mouthwash like Listerine for 60 seconds, twice a day to reduce bacteria and viruses.
Avoid Tobacco
Don’t smoke or chew tobacco, which raises your oral cancer risk even higher if HPV is present.
Eat a Healthy Diet
Consume fruits and vegetables daily for vitamins that support a strong immune response against viruses.
Limit Alcohol
Heavy alcohol weakens your immune system’s ability to fight HPV. Only drink in moderation, if at all.
Consistency with these best practices is key for lowering HPV transmission and keeping your mouth as healthy as possible.
Signs and Symptoms of Oral HPV
Most oral HPV cases cause no symptoms. But the virus can trigger abnormalities over time. Contact your physician promptly about:
Mouth Lesions
Noticeable sores, bumps or lesions in your mouth that linger longer than 2 weeks.
Tongue Discoloration
Unexplained white or red patches on your tongue.
Persistent Sore Throat
A sore throat lasting longer than a few weeks, without other cold symptoms.
Swollen Lymph Nodes
Tender, swollen glands in your neck, under your jaw, or around your collarbone.
Ear Pain
Dull mouth pain radiating to your ears, which may signal tumors near the tonsils.
Hoarse Voice
A raspy, harsh voice or trouble projecting loudly could indicate throat/vocal cord tumors.
Don’t ignore these common warning signs. Early specialist intervention is key to treating precancerous lesions before cancer develops.
Professional Treatments for HPV
If a dentist detects HPV-related oral abnormalities, prompt treatment helps stop progression. Typical methods include:
Surgery
Precancerous lesions are removed through minimally invasive excision. Lasers, electrocautery or cryotherapy may be used.
Chemotherapy Medications
Anti-cancer drugs are applied topically or injected directly into lesions to destroy abnormal cells.
Immunotherapy
Medications boost the immune system to better target and eradicate cancerous cells.
Radiation
High energy X-rays are administered externally to shrink tumors and kill cancerous growths.

FAQs
Is it okay to add hot sauce or chili powder to my food?
It's best to limit added spices like hot sauce and chili powder. The capsaicin can accumulate and irritate the colon. Mild seasonings are recommended instead while your diverticulosis heals.
If I only eat a little chili once a week, is that alright?
Eating a small amount of mild chili occasionally may be fine if you tolerate it well. Pay attention to your symptoms - if you experience discomfort, avoid chili until your diverticulosis improves.
Are all types of chili off limits?
Not necessarily. Mild chili made with lean ground turkey or chicken, fiber-rich beans and limited fatty toppings can be worked into your diet in moderation. Skip the extreme heat of habaneros though.
Can chili cause diverticulitis or make it worse?
There is no definitive proof that chili causes diverticulitis. But it may potentially irritate existing pouches and worsen symptoms during a diverticulitis flare-up. It's best avoided at that time.
If chili gives me diarrhea, does that mean I can't ever eat it?
You may need to avoid chili long term if it consistently causes diarrhea or other digestive issues. Some people have a lower spice tolerance. Focus on flavored dishes without chili powder or cayenne.
