Listerine and Chlorhexidine are two of the most popular mouthwashes available on the market. Both of them are used to fight against bad breath, gingivitis, and plaque buildup.
However, they differ in their active ingredients, effectiveness, and potential side effects.
In this article, we will compare Listerine and Chlorhexidine, explain their differences, and help you decide which one is better for you.
Listerine is an alcohol-based mouthwash that contains essential oils such as eucalyptol, menthol, thymol, and methyl salicylate. It is known for its refreshing taste and is widely used as a breath freshener.
Listerine is also effective in killing bacteria that cause bad breath and gum disease. It is available in various flavors and strengths, including original, cool mint, fresh burst, and total care.
However, Listerine may cause a burning sensation in the mouth and can stain teeth if used excessively.
Chlorhexidine, on the other hand, is a prescription-only mouthwash that contains an antiseptic called chlorhexidine gluconate. It is used to treat gum disease, gingivitis, and other oral infections.
Chlorhexidine is more potent than Listerine and can kill bacteria for up to 12 hours after use. However, it can cause side effects such as staining of teeth, tongue, and gums, altered taste sensation, and dry mouth.
Chlorhexidine is not recommended for long-term use and should only be used under the guidance of a dentist or healthcare professional.
What Is Listerine?
Listerine is a popular brand of mouthwash that has been around for over 100 years. It is used to freshen breath, kill germs, and improve oral health. The mouthwash is named after Joseph Lister, a British surgeon who pioneered the use of antiseptics in surgery.
Listerine was originally marketed as a surgical antiseptic, but it was later rebranded as a mouthwash.
History of Listerine
Listerine was first introduced in 1879 by Dr. Joseph Lawrence, a St. Louis physician. The original formula contained a combination of alcohol, eucalyptol, menthol, and thymol.
It was marketed as a surgical antiseptic and was used to clean wounds and prevent infections.
In 1914, the Lambert Pharmacal Company purchased the rights to Listerine and began marketing it as a mouthwash. The company claimed that Listerine could cure bad breath, prevent tooth decay, and improve oral health.
These claims were not supported by scientific evidence, but the marketing campaign was successful, and Listerine became a household name.
Active Ingredients in Listerine
Listerine contains a combination of active ingredients that work together to kill germs and freshen breath.
The four main active ingredients in Listerine are:
- Thymol: A natural oil derived from thyme that has antiseptic properties.
- Eucalyptol: A natural oil derived from eucalyptus that has antibacterial properties.
- Menthol: A natural oil derived from mint that has a cooling and refreshing effect.
- Methyl salicylate: A natural oil derived from wintergreen that has antiseptic properties.
Listerine also contains alcohol, which acts as a solvent and helps to dissolve the other ingredients.
The alcohol content in Listerine is around 21.6%, which is higher than most other mouthwashes.
This can cause a burning sensation in the mouth, especially if the mouthwash is used for an extended period of time.
What Is Chlorhexidine?
Chlorhexidine is an antiseptic agent used in oral care products to prevent and treat gum disease, gingivitis, and other oral infections. It is also used in surgical settings and as a wound cleanser.
History of Chlorhexidine
Chlorhexidine was first synthesized in the 1950s and has been widely used since then due to its broad-spectrum antimicrobial activity.
It is a cationic bisbiguanide compound that works by disrupting the cell membranes of bacteria and fungi, leading to their death.
Active Ingredients in Chlorhexidine
The active ingredient in chlorhexidine is chlorhexidine gluconate, which is available in different concentrations ranging from 0.12% to 4%. The higher the concentration, the stronger the antimicrobial activity.
Chlorhexidine gluconate is a positively charged molecule that binds to the negatively charged cell walls of bacteria and fungi, disrupting their structure and function. It is effective against a wide range of microorganisms, including gram-positive and gram-negative bacteria, fungi, and viruses.
In addition to chlorhexidine gluconate, chlorhexidine formulations may also contain other ingredients such as alcohol, flavoring agents, and preservatives. These ingredients may affect the efficacy and safety of the product.
Overall, chlorhexidine is a powerful antiseptic agent that can help prevent and treat oral infections. However, it may have some side effects such as staining of teeth, altered taste sensation, and allergic reactions.
It is important to use chlorhexidine products as directed and to consult a healthcare professional if any adverse reactions occur.
Key Differences Between Listerine and Chlorhexidine
Listerine and Chlorhexidine are two popular mouthwashes that are used to maintain oral hygiene. While they are both effective in reducing plaque and gingivitis, there are some key differences between the two.
The active ingredient in Listerine is essential oils, such as eucalyptol, menthol, thymol, and methyl salicylate. These oils work together to kill bacteria and freshen breath.
On the other hand, Chlorhexidine contains chlorhexidine gluconate, which is a powerful antiseptic that kills bacteria and prevents the formation of plaque.
Listerine contains alcohol, which can be a concern for some people. Alcohol can cause dry mouth, which can lead to bad breath and other oral health problems.
However, the alcohol content in Listerine is relatively low, and it is generally considered safe to use.
Chlorhexidine, on the other hand, does not contain alcohol, making it a good option for people who are sensitive to alcohol.
Chlorhexidine has a reputation for causing staining on teeth and dental restorations. This is because it can bind to the surface of the teeth and create a brownish-yellow discoloration.
However, this staining is generally reversible and can be removed by a dental professional.
Listerine, on the other hand, does not typically cause staining, making it a good option for people who are concerned about the appearance of their teeth.
Prescription vs. Over-the-Counter
Chlorhexidine is a prescription mouthwash, which means that it can only be obtained with a prescription from a dentist or doctor. Listerine, on the other hand, is available over-the-counter and can be purchased at most drug stores.
Overall, both Listerine and Chlorhexidine are effective options for maintaining oral hygiene. The choice between the two will depend on personal preferences, sensitivity to alcohol, and the need for prescription-strength mouthwash.
Effectiveness of Listerine vs. Chlorhexidine
When it comes to choosing between Listerine and Chlorhexidine for oral hygiene, gum health, and tooth decay prevention, it is important to consider their effectiveness.
Listerine and Chlorhexidine are both effective in reducing plaque and gingivitis.
According to a study published in the Journal of Dental Hygiene, Chlorhexidine is the most effective antiseptic mouth rinse available today. It tightly binds to tooth structure, oral tissues, and dental plaque, resulting in 8 to 12 hour substantivity.
However, it can cause side effects such as brown staining, calculus formation, and temporary loss of taste, which limit its long-term use.
On the other hand, Listerine is almost as effective in killing plaque organisms as Chlorhexidine and has the advantage of being sold as a generic. It is also available without a prescription and is much less expensive and doesn’t stain teeth.
Both Listerine and Chlorhexidine are effective in reducing gingivitis. A study published in the Journal of Dental Hygiene found that Chlorhexidine and Listerine significantly reduced plaque growth and gingivitis compared to a placebo. However, Chlorhexidine was more effective than Listerine.
Tooth Decay Prevention
Chlorhexidine has been shown to be effective in reducing tooth decay. According to a study published in the Journal of Dental Research, Chlorhexidine reduced the incidence of tooth decay by 40% in high-risk individuals.
Listerine, on the other hand, has not been shown to be effective in preventing tooth decay.
In conclusion, both Listerine and Chlorhexidine are effective in reducing plaque and gingivitis, but Chlorhexidine is more effective. Chlorhexidine is also effective in reducing tooth decay, while Listerine is not.
However, Chlorhexidine can cause side effects such as brown staining, calculus formation, and temporary loss of taste, which limit its long-term use.
Side Effects of Listerine and Chlorhexidine
Both Listerine and Chlorhexidine have potential side effects that users should be aware of.
Here are some of the most common side effects associated with each mouthwash:
- Staining: Listerine has been known to cause staining of the teeth and tongue. This is usually temporary and can be removed with regular brushing and dental cleanings.
- Dry Mouth: Listerine can cause dry mouth, which can lead to bad breath and other oral health problems.
- Burning Sensation: Some people may experience a burning sensation in their mouth after using Listerine. This is usually mild and goes away quickly.
- Allergic Reactions: In rare cases, some people may have an allergic reaction to one of the ingredients in Listerine. Symptoms can include itching, swelling, and difficulty breathing.
- Staining: Chlorhexidine can cause brown stains on the teeth, tongue, and other parts of the mouth. These stains are usually temporary and can be removed with dental cleanings.
- Dry Mouth: Like Listerine, Chlorhexidine can cause dry mouth, which can lead to bad breath and other oral health problems.
- Taste Alterations: Some people may experience a temporary alteration in their sense of taste after using Chlorhexidine.
- Allergic Reactions: In rare cases, some people may have an allergic reaction to Chlorhexidine. Symptoms can include itching, swelling, and difficulty breathing.
It is important to note that not everyone will experience these side effects. If you are concerned about the potential side effects of Listerine or Chlorhexidine, talk to your dentist or healthcare provider.
They can help you determine which mouthwash is right for you and provide guidance on how to use it safely.
Which One Is Better?
When it comes to choosing between Listerine and Chlorhexidine, the answer depends on various factors.
Both mouthwashes have their own benefits and drawbacks, and what works for one person may not work for another.
However, based on research and expert opinions, Listerine appears to be the better choice for most people.
One of the main advantages of Listerine is that it is easily available over the counter and does not require a prescription. On the other hand, Chlorhexidine is a prescription mouthwash, which means that it may not be as easily accessible for some people.
Additionally, Chlorhexidine can cause staining of teeth and tongue, which can be a turn-off for some users.
Another factor to consider is the effectiveness of the mouthwash. Both Listerine and Chlorhexidine are effective in killing bacteria that cause bad breath and gum disease.

Cost is another consideration. Chlorhexidine is generally more expensive than Listerine, which can be a deciding factor for some people. Listerine is also available in generic form, making it even more affordable.
In summary, both Listerine and Chlorhexidine have their benefits and drawbacks. However, for most people, Listerine is the better choice due to its availability, affordability, and effectiveness.
In summary, both Listerine and Chlorhexidine have their pros and cons. Listerine is a good option for those who want a mouthwash that is readily available and affordable. It is also effective against plaque organisms and does not stain teeth.
On the other hand, Chlorhexidine is a more potent antiseptic that is widely used in dental clinics and hospitals. It has a longer-lasting effect, up to 12 hours, and is more effective in reducing plaque growth and gingivitis than Listerine.
However, it can cause side effects such as brown staining, calculus formation, and temporary loss of taste.
When deciding between the two, it is important to consider one’s specific needs and preferences. For instance, someone who is looking for a long-lasting antiseptic rinse that is highly effective against plaque and gingivitis may prefer Chlorhexidine, despite its side effects.
On the other hand, someone who is looking for a more affordable and readily available option that is effective against plaque organisms may prefer Listerine.
It is also worth noting that there are other mouthwash options available that may be suitable for certain individuals.
For instance, those with dry mouth may benefit from using a mouthwash that contains xylitol, which can stimulate saliva production.
Additionally, those with sensitive teeth may benefit from using a mouthwash that contains fluoride, which can help strengthen tooth enamel.
Ultimately, the best mouthwash for an individual will depend on their specific needs and preferences. It is important to consult with a dentist or healthcare professional to determine the best option for one’s oral health.
