The appropriate Listerine® product depends on the specific oral-health goal and active ingredients.

The History of Listerine®

Listerine® has a history extending back to the 19th century and was named in recognition of British surgeon Joseph Lister, whose work helped advance antiseptic surgical practices.

Over time, Listerine® evolved into a major oral-care brand and became particularly associated with antiseptic mouthwash.

Today’s range extends well beyond the original formula, with different products developed for gum health, cavity prevention, fresh breath, whitening, sensitivity preferences, and everyday oral hygiene.

How Listerine® Mouthwash Works

Different Listerine® formulas work in different ways.

Traditional antiseptic Listerine® rinses use a combination of essential-oil active ingredients commonly including compounds such as:

• Eucalyptol

• Menthol

• Methyl salicylate

• Thymol

These ingredients are used in certain formulations to help reduce plaque and gingivitis when the rinse is used according to directions.

Other Listerine® products may use fluoride or different active ingredients, so benefits should always be matched to the individual product rather than applied to the entire brand.

Listerine® for Plaque & Gum Health

Plaque is a bacterial biofilm that continually develops on the teeth.

If it is not adequately removed, plaque accumulation around the gumline can contribute to gingivitis, characterized by inflammation, redness, swelling, or bleeding of the gums.

Selected Listerine® antiseptic mouthwashes can complement mechanical cleaning by helping reduce plaque and gingivitis.

Mouthwash should not replace:

• Brushing with fluoride toothpaste

• Flossing or other interdental cleaning

• Professional dental examinations

• Professional dental cleaning when needed

Listerine® for Fresh Breath

Bad breath can develop from bacteria and debris within the mouth, including on the tongue and between teeth.

Listerine® fresh-breath and antiseptic rinses can help reduce odour-causing oral bacteria and provide a fresher mouthfeel.

For persistent bad breath, however, simply masking odour may not address the underlying cause.

Ongoing halitosis can be associated with gum disease, dental problems, dry mouth, smoking, certain foods, or medical conditions and may warrant professional assessment.

Alcohol vs Alcohol-Free Listerine®

Listerine® offers both traditional and alcohol-free mouthwash options.

Traditional Formulas

Some Listerine® products contain alcohol as part of the formulation.

Alcohol-Free Formulas

These may appeal to people who:

• Prefer a milder mouthfeel

• Find traditional rinses uncomfortable

• Prefer to avoid alcohol-containing oral-care products

• Have individual oral-care preferences that favour alcohol-free formulations

Alcohol-free does not necessarily mean less effective—the relevant active ingredients and intended claims of the individual product matter more.

Fluoride Listerine® Mouthwash

Selected Listerine® products contain fluoride to help protect against dental cavities.

Fluoride can help strengthen tooth enamel and increase resistance to acid-related demineralization.

A fluoride mouthwash may complement fluoride toothpaste for some people, but the appropriate routine depends on individual cavity risk and dental needs.

Follow the specific product directions, including any instructions about eating, drinking, or rinsing after use.

Whitening Listerine® Mouthwash

Selected Listerine® formulas are designed to complement a whitening-focused oral-care routine.

Depending on the formulation, these products may help reduce or prevent certain surface stains.

Whitening mouthwash should not be expected to produce the same degree of colour change as professional dental whitening or stronger dedicated whitening treatments.

It also cannot change the colour of fillings, crowns, veneers, or other dental restorations.

Tartar-Control Formulas

Tartar, or dental calculus, develops when plaque mineralizes and hardens on the teeth.

Selected mouthwash formulas may help reduce conditions that contribute to tartar buildup, but existing hardened tartar cannot simply be rinsed away with mouthwash.

Once calculus has formed, professional dental cleaning is generally required for its removal.

Choosing a Listerine® Mouthwash

For Plaque & Gingivitis

Look for a Listerine® formula specifically labelled for antiseptic plaque and gingivitis control.

For Fresh Breath

Choose an appropriate fresh-breath or antiseptic rinse according to your preferred flavour and intensity.

For Alcohol-Free Care

Select a formula explicitly labelled alcohol-free.

For Cavity Protection

Look for a product containing fluoride and carrying an appropriate anticavity indication.

For Whitening

Choose a formula specifically designed to help manage surface staining.

For Tartar Control

Select a product whose label specifically identifies tartar-control benefits.

Not every Listerine® mouthwash provides all of these benefits.

Building a Complete Oral-Care Routine

Mouthwash works best as one component of comprehensive oral hygiene.

A strong daily routine generally includes:

1. Brush thoroughly
Brush with fluoride toothpaste according to appropriate dental recommendations.

2. Clean between the teeth
Use dental floss, interdental brushes, or another suitable method.

3. Clean the tongue when appropriate
Tongue cleaning can help remove debris and bacteria associated with bad breath.

4. Use mouthwash appropriately
Follow the directions for your specific Listerine® product.

5. Maintain professional dental care
Regular examinations help identify cavities, gum disease, and other oral-health problems that home care alone cannot diagnose.

Listerine® Safety & Appropriate Use

Use Listerine® according to the directions and age restrictions on the specific bottle.

Mouthwash is intended to be rinsed and spit out, not swallowed.

Keep mouthwash securely away from young children.

If significant burning, irritation, swelling, or another unexpected reaction develops, discontinue use and seek appropriate advice.

Persistent gum bleeding, dental pain, loose teeth, mouth sores, swelling, or ongoing bad breath should be evaluated by a dentist rather than managed indefinitely with mouthwash.

FAQs

What is Listerine® used for?
Depending on the formula, Listerine® may help reduce plaque and gingivitis, freshen breath, provide fluoride cavity protection, help manage tartar buildup, or complement a whitening routine.

Does Listerine® kill 99.9% of germs?
Specific Listerine® products may carry validated germ-kill claims under particular test conditions. Because formulations and claims differ, the percentage should be attributed only to the individual product whose current label supports it rather than to every Listerine® mouthwash.

Does Listerine® help prevent gingivitis?
Selected antiseptic Listerine® formulas are intended to help reduce plaque and gingivitis when used according to directions as part of an appropriate oral-hygiene routine.

Can Listerine® replace brushing and flossing?
No. Mouthwash complements mechanical plaque removal but should not replace brushing or cleaning between the teeth.

Is alcohol-free Listerine® effective?
Alcohol-free products can still contain active ingredients designed for oral-care benefits. Effectiveness depends on the particular formulation and intended use rather than the presence of alcohol alone.

Does Listerine® contain fluoride?
Some Listerine® products contain fluoride, while others do not. Check the individual product label if cavity protection is your priority.

Can Listerine® remove tartar?
Mouthwash cannot remove hardened tartar that has already formed. Existing dental calculus generally requires professional removal.

Can children use Listerine®?
Age recommendations differ between formulas. Always follow the age restrictions and directions on the specific product and ensure children who use mouthwash can reliably rinse and spit it out.

Why does mouthwash burn?
The sensation can result from the formulation and active or flavouring ingredients. A stronger sensation does not necessarily indicate better cleaning. People who dislike it may prefer an appropriate alcohol-free or milder formula.
