How to Use Mouthwash (and Who Really Needs It) Who We Are Health Even if you brush, floss, and get dental cleanings regularly, sometimes your oral health needs a little extra help. The best mouthwash kills the bacteria in your mouth that can cause bad breath and contribute to cavities and gum disease. When used alongside healthy brushing habits, mouthwash can help improve all three for people with a higher risk of these problems, explains Scott Cardall, DMD, a Harvard-trained orthodontist and founder of Orem Orthodontics in Utah. But which mouthwash will actually help is another story. We spoke with two dentists, Dr. Cardall and New York-based periodontist Navid Rahmani, DDS, New York-based periodontist and founder of Manhattan Periodontics in New York City, to understand how to most effectively use mouthwash (and who really needs it), as well as how to select one with the right ingredients to help you reach your dental hygiene goals. Based on their feedback, we rigorously researched products from the top brands. We also had an orthodontist on our Medical Expert Board review this article for medical and scientific accuracy.

Its main ingredients are sodium hydroxide, which helps maintain the pH balance in your mouth, and peppermint oil, which naturally combats bad breath and kills bacteria to help control plaque and gingivitis. It’s also free of alcohol, so it won’t cause any burning sensation, as well as allergens like benzalkonium chloride. We also love that the minty flavor is mild and doesn’t leave a strong aftertaste despite being strong enough to nix bad breath. The company was founded by a dentist, and this TheraBreath formula has the ADA Seal of Acceptance to stand behind its efficacy and quality. It's Worth Noting It isn’t ideal for dry mouth. Product Details Key ingredients: Sodium hydroxide, peppermint oilFlavor: Mint Size: 16 fluid ounces Best for Bad Breath Colgate Total 12 Protection Alcohol-Free Mouthwash PHOTO: Amazon $17 $15 at Amazon $6 at Walmart View on CVS Why We Like It Bad breath is the number one reason for the average person to use mouthwash, both our experts agree. Bad breath—called halitosis—is caused by odor-causing bacteria in your mouth. Colgate Total contains cetylpyridinium chloride, which is an antimicrobial that kills bacteria. While a mouthwash can help bad breath in the moment, the best way to fix chronic bad breath is to get regular dental cleanings and brush and floss regularly, Dr. Cardall says. That said, the protection provided by this mouthwash lasts for 12 hours, so it stays effective even after you eat or drink. Additionally, it’s alcohol-free, so its bright peppermint flavor refreshes your mouth without burning or stinging. It's Worth Noting It doesn’t have an ADA seal of acceptance. Product Details Key ingredients: Cetylpyridinium chlorideFlavor: MintSize: 33.8 fluid ounces Best Natural Nature's Answer PerioBrite Natural Mouthwash, Wintermint PHOTO: Amazon $15 $12 at Amazon $9 at IHerb View on Vitacost Why We Like It If you’re looking for the power of plant medicine, Nature’s Answer PerioBrite is formulated by a dentist and utilizes Echinacea purpurea and Centella asiatica, two natural ingredients that Dr. Rahmani says help to reduce gingivitis and aid in gum repair. This all-natural mouthwash also contains wintergreen and peppermint oil to freshen bad breath, and the flavor is bright but not overwhelming. This formula is free of alcohol and any additives, and contains a slew of other herbs and oils known to help clean the mouth. Nature’s Answer uses a unique, proprietary process of cold extraction to capture the plant's raw power without heating and destroying it. It's Worth Noting It’s more expensive than other brands. Product Details Key ingredients: Glycerin, methyl salicylate, xylitol, Bio-SaponinsFlavor: WintermintSize: 16 fluid ounces Best for Dry Mouth Biotene Dry Mouth Oral Rinse PHOTO: Amazon $15 $11 at Amazon $23 $22 at Walmart $9 at Walgreens Why We Like It People who have dry mouth—whether naturally or due to something like medication or an autoimmune disease—secrete less saliva. This can lead to more cavities, since saliva has natural antibodies to fight cavities and bacteria that cause gum disease, Dr. Rahmani explains. Dr. Cardall likes Biotene Dry Mouth Oral Rinse for this, since its main ingredients are water and glycerin, a compound used to retain moisture. Dr. Cardall also likes that Biotene does not contain many of the chemicals that can contribute to irritation, such as alcohol. The mouthwash has a nice mouth-feel thanks to the glycerin, and leaves your mouth feeling minty fresh instead of chemically like a lot of other mouthwashes designed for this issue. It also contains xylitol, a natural sweetener that helps to prevent cavities, according to Dr. Cardall. If you have dry mouth, you should also use a toothpaste with fluoride to prevent cavities, and make sure you wait until after brushing to use mouthwash so you don't rinse the fluoride away, Dr. Rahmani advises. It's Worth Noting It doesn’t include a cap for measuring mouthwash. Product Details Key ingredients: Glycerin, xylitolFlavor: MintSize: 33.8 fluid ounces Best for Cavity Protection ACT Restoring Fluoride Mouthwash PHOTO: Amazon $7 at Amazon $7 at Target $14 $7 at Walmart Why We Like It Mouthwash can’t prevent cavities—only proper brushing and a healthy diet can do that, both our experts point out. But using a mouthwash with fluoride can help remineralize the teeth and strengthen enamel, making your teeth more resistant to the bacteria and acid that cause cavities and other tooth decay. We like ACT Restoring Mouthwash because it uses sodium fluoride to help remineralize your teeth. This mouthwash comes in a refreshing minty flavor, and at an affordable price. It’s also free of alcohol, which not only burns but also can further dry out your mouth, exacerbating cavity issues. If you have dry mouth or frequent cavities, this mouthwash will help. It's Worth Noting While it doesn’t contain any alcohol, it does have a slightly chemical taste. Product Details Key ingredients: Sodium fluorideFlavor: MintSize: 33.8 fluid ounces Best for Plaque Listerine Total Care Anticavity Flouride Mouthwash PHOTO: Walmart $23 $17 at Amazon $9 at Target $9 at Walmart Why We Like It Listerine Total Care uses antibacterial essential oils, namely eucalyptol, to limit bacterial growth. The brand’s blend of essential oils includes eucalyptol and menthol, which both work as antifungal ingredients. This blend was shown to be effective at reducing plaque and gingivitis when part of a regular dental routine. Dr. Rahmani says anti-plaque mouthwashes like this one can reduce gingivitis by preventing plaque from colonizing in your mouth. The essential oil blend, combined with fluoride and alcohol, help keep plaque at bay, especially above the gumline. It's Worth Noting The strong mint flavor may be harsh for some, and this mouthwash contains alcohol. Product Details Key ingredients: Eucalyptol, menthol, methyl salicylate, thymolFlavor: MintSize: 33 fluid ounces Best for Gingivitis Listerine Freshburst PHOTO: Amazon $8 at Amazon $8 at Target $14 $9 at Walmart Why We Like It People who have a history of inflamed and puffy gums or bone loss are at higher risk for developing gingivitis and periodontitis, Dr. Cardall says. For this, a rinse like Listerine Freshburst can help you stay on top of regular brushing and flossing. Listerine Freshburst uses different alcohols and four essential oils to kill gingivitis-causing germs. Listerine is clinically proven to kill the bacteria that causes gingivitis and periodontitis (though it won’t help with cavity prevention, Dr. Cardall points out). This mouthwash has the ADA seal of acceptance to stand behind its effectiveness and safety. The alcohol and bright mint are great for freshening breath, allowing this mouthwash to do double duty. It's Worth Noting Because it contains alcohol, it does burn slightly, and the Freshburst minty flavor is on the stronger side. Product Details Key ingredients: Eucalyptol, menthol, methyl salicylate, thymol, alcoholFlavor: SpearmintSize: 16.9 fluid ounces Best for Sensitive Teeth CloSYS Sensitive Mouthwash PHOTO: Amazon $15 $12 at Amazon $15 at Walgreens $17 $12 at Walmart Why We Like It If you have a sensitive mouth, it can be hard to garner the benefits of a mouthwash among the price of a painful rinse. CloSYS Sensitive Mouthwash is formulated to reduce bad breath while being non-burning and exceptionally gentle. It’s free of some of the ingredients commonly found in mouthwash, including alcohol, triclosan, and sulfate, but still carries the ADA Seal of Acceptance. CloSYS Sensitive Mouthwash has a gentle mint flavor to help your mouth feel refreshed and is also available in an unflavored version. The active ingredient is chlorine dioxide, a disinfectant that is often used to clean drinking water, so you can rest assured it will get your mouth squeaky clean. It's Worth Noting It has a slight chemical smell, but that doesn’t affect its flavor. Product Details Key ingredients: Chlorine dioxide, trisodium phosphateFlavor: MintSize: 32 fluid ounces Best Scope Crest Scope Get Fresh Mouthwash PHOTO: Amazon $13 at Amazon Why We Like It Scope is a heritage brand that both dentists and people have trusted for years. Crest Scope Get Fresh is our top pick from the brand’s lineup because it’s effective against odor- and plaque-causing bacteria. Its main ingredients, cetylpyridinium chloride and alcohol, help prevent plaque from appearing and stop the growth of bad breath-causing bacteria that’s already present in your mouth. The minty fresh flavor will leave your mouth feeling and tasting refreshing, although that does come with a bit of a bite thanks to the alcohol. Available on most store shelves, this mouthwash is also a super affordable addition to a regular dental routine. It's Worth Noting It doesn’t carry the ADA Seal. Product Details Key ingredients: Cetylpyridinium chloride, alcoholFlavor: MintSize: 33 fluid ounces Best Listerine Listerine Original PHOTO: Amazon $10 $7 at Amazon $8 at Target $19 $15 at Walmart Why We Like It While generic versions of the product have almost the same efficacy, Listerine is a popular and widely-available brand name that dentists know prevents gum disease, says Dr. Cardall. Listerine Original uses four different alcohols, which work to kill the bacteria that causes gum disease and bad breath for up to 24 hours. We consider the Original the best Listerine because in addition to having everything to improve your oral health, it also boasts the ADA Seal of Acceptance, which not all Listerine formulas do. It's Worth Noting It doesn’t contain fluoride, which people prone to cavities may need. Product Details Key ingredients: Alcohol, mentholFlavor: OriginalSize: 33 fluid ounces How We Selected We selected the best mouthwashes based first and foremost on insight from two dental experts, who gave us their advice on what a healthy mouthwash should and shouldn’t contain. Based on their professional guidance, we narrowed down the top selections to these best picks based on criteria of what makes the best mouthwash and reviews of which are worth the money. Specifically, we considered the effectiveness of each mouthwash's active ingredients, as well as flavor and value. The Experts We interviewed the following experts to learn what to look for in a quality mouthwash: Scott Cardall, DMD, a Harvard-trained orthodontist and founder of Orem Orthodontics in UtahNavid Rahmani, DDS, New York-based periodontist and founder of Manhattan Periodontics in Midtown Ingredients to Look For & What to Avoid What to look for in a mouthwash depends on what specific issue you’re hoping to tackle. While people with healthy mouths are fine to use most types of mouthwash, those with other dental conditions should look for certain ingredients. Fluoride: If you’re prone to cavities, look for fluoride, which helps to remineralize your teeth and make them stronger against bacteria. Glycerin: If you’re prone to dry mouth, choose a mouthwash with glycerin, which will help add moisture to your mouth. Fluoride also helps to prevent cavities, which folks with dry mouth are more prone to see when saliva isn’t present to wash away bacteria, plaque, and tartar. Peridontitis-fighting ingredients: If you need help controlling plaque and gingivitis, look for any ingredient that kills periodontitis-causing bacteria. These include alcohol, chlorhexidine, or certain essential oils. All-natural ingredients: If you’re looking to stay all-natural, look for Sambucus nigra, Echinacea purpurea, and Hydrocotyle asiatica (aka Centella asiatica), all of which are plant-based and shown to reduce gingivitis and repair your gums, says Dr. Rahmani. Whitening ingredients: If you want whiter teeth, try adding a whitening toothpaste to your regular regimen. Studies have shown that whitening mouthwashes are not only not effective on changing tooth color, but they are also potentially erosive to your enamel thanks to their low pH. Ingredients you may want to avoid include: Alcohol: Alcohol is key in many mouthwash formulas thanks to its natural ability to kill bacteria that causes bad breath and gingivitis. That being said, you can definitely find mouthwashes that are alcohol-free and therefore don’t burn when you use them. If you have dry mouth, are prone to cavities, or are elderly, skip alcohol as it usually dries your mouth out further and exacerbates bacteria issues, Dr. Rahmani advises. It’s not harmful to most other people, says Dr. Cardall, but it can cause an unpleasant burning sensation, so it’s mostly a personal choice to skip this ingredient or not. Additional fluoride: Because most toothpastes and drinking water are both fluoridated, you’re likely already seeing the benefits of that ingredient without needing to add an extra dose to your dental routine. Dr. Rahmani explains that if you don’t have dry mouth or frequent cavities, you don’t need to look for fluoride on your mouthwash’s ingredients list. A note about hydrogen peroxide Never use straight hydrogen peroxide as mouthwash. It’s present in some products, but that’s when it’s diluted with other ingredients and lots of water. Moreover, it may not even be the most effective mouthwash ingredient, Dr. Cardall points out. What Does the ADA Seal Mean? A seal from the American Dental Association means that a product has been proven effective in lab studies or other research submitted to the ADA. While there are other effective mouthwashes that don’t have the ADA seal, they aren’t always backed by the same level of research as products vetted by the ADA. The ADA seal requires only a 15% level of improvement for a product to obtain it. How to Use Mouthwash (and Who Really Needs It) For those who brush their teeth twice a day and floss regularly, the main benefit of mouthwash is that it will freshen your breath, Dr. Rahmani explains. However, mouthwashes can have real value for those looking to attack a certain oral health care problem, says Dr. Cardall. In other words, mouthwash is generally less important than brushing and flossing, but it’s a nice add-on to tackle specific predispositions in an otherwise healthy routine. Generally, you can use a mouthwash twice a day. Swish the recommended amount in your mouth for a full 30 seconds, gargle, then spit. Do not rinse with water, as this prevents ingredients like fluoride from effectively protecting your teeth from cavities. You can use mouthwash either before or after brushing. Both are effective, according to the American Dental Association, though you should follow the manufacturer’s instructions to see the maximum benefit. If you’re prone to cavities and not using a mouthwash with fluoride, Dr. Rahmani says you should swish before brushing; using mouthwash after brushing your teeth will rinse away the crucial, cavity-preventing fluoride your toothpaste contains. If you have dry mouth or are predisposed to gum disease or cavities, the right mouthwash can help. It's also worth noting that kids younger than six years old shouldn’t use mouthwash unless instructed by their dentist. Who We Are Rachael Schultz is a health and wellness writer for Health.com.
