Using the best mouthwash can be a great finishing step in your daily oral health routine. Consider it a proverbial cherry on top of the dental sundae. While it's true that you don't need a mouthwash in your lineup to have stellar oral health, it can offer a range of added benefits — from strengthening and whitening teeth to taming bad breath, soothing gums and reducing sensitivity — that can give you a bit of extra support when you need it. To help discern which mouthwash might be most deserving of a spot on your bathroom counter, we consulted four dentists about the best mouthwashes fit to tackle an array of oral health needs.
Listerine Total Care Anticavity Mouthwash
If you're looking for an all-in-one mouthwash packed with whole-mouth benefits, Dr. Michael J. Wei, cosmetic dentist and founder of Manhattan Cosmetic, recommends this Listerine Total Care mouthwash. Made with fluoride for cavity protection, this rinse also fights plaque buildup and comes packed with essential oils to help kill bad breath-causing germs.
Biotène Dry Mouth Oral Rinse
'If you're managing dry mouth — whether due to medication, age or health conditions like Sjögren's [Syndrome] — Biotène Dry Mouth Oral Rinse is a highly recommended solution,' said Dr. Erin Fraundorf, an orthodontist and the founder of Boca Orthodontic and Whitening Studio in Missouri. Formulated with moisturizing agents like glycerin and xylitol to help relieve symptoms of dry mouth for several hours, Fraundorf said you can use this Biotène rinse several times a day to help with saliva replacement. In addition to having a balanced pH that helps support good oral health, Biotène is also alcohol- and sugar-free, so it won't further irritate sensitive gums or contribute to tooth decay.
Crest 3D White Glamorous White Mouthwash
Dr. Kevin B. Sands, a cosmetic dentist based in Beverly Hills, California, said this Crest 3D White rinse is his go-to whitening mouthwash. Formulated with hydrogen peroxide for whitening, this alcohol-free mouthwash promises fresh breath after every use and a brighter smile in just seven days.
Smart Mouth Clinical Prescription-Strength Oral Rinse
Dr. Anjali Rajpal, a cosmetic dentist and the founder of Beverly Hills Dental Arts, said this Smart Mouth rinse uses zinc ion technology to create an odor-blocking barrier in the mouth that targets bad breath at the source. It's also clinically proven to help prevent gingivitis and bleeding gums.
TheraBreath Fresh Breath Oral Rinse
Therabreath's mouthwashes, like this Fresh Breath version, are a dentist favorite for good reason. Made to neutralize odor-causing bacteria and deliver 24-hour fresh breath protection, this mouthwash is also alcohol-free, which, according to Fraundorf, is important for daily use. 'The acid in mouth rinse with alcohol creates an acidic environment and actually promotes demineralization of your enamel,' she said. 'It additionally can lead to bad breath by drying out your mouth, leading to a buildup of bad bacteria that cause bad breath, and killing good bacteria, leading to an imbalance in the microflora that causes bad breath.'
Act Total Care Anticavity Fluoride Mouthwash
Both Sands and Wei like this affordable and effective mouthwash from Act. Made with sodium fluoride to help strengthen enamel, it's a great option for those looking to prevent cavities or who are already cavity-prone, according to Wei. It's also formulated without alcohol, so it won't sting or leave your mouth feeling dry after use either.
GuruNanda Dual-Barrel Breath Harmonizer Mouthwash
The dual-barrel chambers in this GuruNanda mouthwash contain an essential oil blend and sodium chlorite that, when mixed together, activate to create an odor-neutralizing and plaque-fighting rinse. Rajpal likes this fluoride-free rinse for those looking for long-lasting fresh breath and a more holistic approach to oral care.
Colgate Total Alcohol-Free Mouthwash
Wei also likes this alcohol-free Colgate mouthwash, which claims to kill 99% of germs that cause bad breath, gingivitis and plaque on contact.
TheraBreath Healthy Gums Oral Rinse
Another fan of TheraBreath's rinses, Sands recommends this alcohol-free option, which is formulated to promote healthy gums. Sands said this dentist-formulated mouthwash is effective at attacking bacteria linked to gum disease while still being gentle enough to use daily.
Closys Healthy Gums Mouthwash
Mouthwashes can help penetrate deeper into gum pockets to reduce inflammation in areas that your toothbrush bristles can't reach. This powerful antibacterial mouthwash by Closys is made with Cloralstan, an antimicrobial agent that eliminates bacteria that can lead to gingivitis and bad breath, making it a good choice for those struggling with sensitive gums.
Essential Oxygen BR Organic Mouthwash and Brushing Rinse
Rajpal also likes this Essential Oxygen rinse, which combines food-grade hydrogen peroxide and a blend of essential oils to help naturally whiten teeth and freshen breath. This rinse can be used before brushing, while brushing or after brushing as a regular mouthwash, plus anytime you just want an extra boost of fresh breath.
Crest Pro-Health Multiprotection Mouthwash
This Crest Pro-Health mouthwash is a favorite of Wei's since it's made to help reduce gum inflammation, prevent plaque buildup and kill bad breath-causing bacteria in the mouth. It's also alcohol-free and perfect for daily use if you want extra prevention against the causes of early gum disease.
Crest 3D White Brilliance Stain Prevention Mouthwash
Though mouthwashes aren't very effective as the main means by which to whiten your teeth, they can boost the load of whitening agents in your overall dental routine. This Crest rinse is safe to use daily, and the hydrogen peroxide-infused formula helps to prevent surface stains from settling into teeth.
Boka Renew Liquid Mouthwash
For those interested in alternatives to traditional fluoride mouthwashes, Fraundorf likes this alcohol-free formula from Boka. Formulated without dyes, harsh chemicals or artificial additives, this Boka Renew mouthwash uses nano-hydroxyapatite to remineralize teeth. Fraundorf said it's also made from 'naturally derived antibacterial agents and botanicals that help reduce plaque and promote fresh breath while maintaining the mouth's natural balance.'
Tom's of Maine Whole Care Mouthwash
A natural mouthwash fortified with fluoride and free from artificial colors or flavors, this Tom's of Maine Whole Care rinse has a thin, water-like feel in the mouth. It also leaves behind a subtle minty aftertaste without any harsh alcohol burn.
SuperMouth Hydroxamin Nonfluoride Mouthwash
If you're sick of mint-flavored mouthwashes — or want something safe for your kiddos to use too — try this SuperMouth wash, which is fluoride-free and available in three ice cream-inspired flavors: vanilla, strawberry and chocolate. While this wash is free from alcohol, essential oils and artificial colors and flavors, it is formulated with nano-hydroxyapatite to help keep teeth strong. There are loads of different mouthwashes out there to choose from, but the one that's best for you will depend on what specific oral concerns you're looking to address. 'Many people choose mouthwash based on flavor or branding without considering whether it meets their specific oral health needs,' Fraundorf said. 'For example, someone dealing with gum inflammation may need an antimicrobial formula, while someone prone to cavities may benefit more from a fluoride-based rinse.'
Fraundorf recommends consulting your dentist to determine your specific oral health needs but offered some common ingredients to be on the lookout for. Mouthwashes formulated with fluoride, calcium phosphate or nano-hydroxyapatite can help to remineralize enamel, which aids in preventing cavities and reducing teeth sensitivity, while ingredients like cetylpyridinium chloride are antimicrobial and can help to reduce plaque and bacteria responsible for gingivitis and bad breath, according to Fraundorf. Rajpal said some natural ingredients such as essential oil blends containing mint, eucalyptus and tea tree oil, or zinc can be helpful for neutralizing odor and freshening breath, adding that some mouthwashes made with synthetic ingredients or artificial dyes might irritate sensitive mouths.
Our dental experts said it's important to remember that mouthwash is not a replacement for regular brushing and flossing. 'While [mouthwash] can be a helpful supplement and add-on to your oral care routine, it doesn't physically remove plaque or food particles the way brushing and flossing do,' Fraundorf said. 'It should always be seen as an add-on, not a substitute.'
Wei said to follow the recommended guidelines for using mouthwash per the instructions on the label, including following the recommended duration of time for rinsing and frequency of use. Both Rajpal and Wei added that you should not rinse your mouth with water immediately after using a mouthwash, since this can wash away active ingredients and reduce the overall effectiveness.
The dental experts we spoke to also cautioned against overusing mouthwash, specifically ones formulated with alcohol. 'Using mouthwash too frequently — especially those with alcohol or strong antibacterial agents — can lead to oral tissue dryness, irritation or disruption of the healthy oral microbiome,' Fraundorf said. 'This is especially important for people with sensitive tissues or dry mouth conditions.'
The following FAQs have been answered by dental experts Dr. Erin Fraundorf, Dr. Anjali Rajpal, Dr. Kevin B. Sands and Dr. Michael J. Wei.
What is the best way to incorporate mouthwash into your existing dental routine?
What is the best way to incorporate mouthwash into your existing dental routine?
The dental experts we spoke to all recommended using mouthwash after brushing and flossing. Rajpal said that brushing and flossing help remove debris and plaque from the tooth surface, while mouthwash can rinse away remaining particles and deliver additional benefits, like bacteria reduction or enamel strengthening.
You can use mouthwash both in the morning and at night, but Fraundorf said you want to be careful not to overuse mouthwash. 'Once or twice a day is usually sufficient, but overuse — particularly with alcohol-based formulas — can lead to excessive dryness, irritation and an imbalanced oral microbiome,' she said. In order for the active ingredients in mouthwash — like fluoride, nano-hydroxyapatite or antibacterial agents — to have the greatest benefit, Fraundorf recommends avoiding eating, drinking or rinsing for at least 30 minutes after using a mouthwash, especially if you're using a therapeutic oral rinse.
What happens if you accidentally swallow mouthwash?
What happens if you accidentally swallow mouthwash?
Though most mouthwashes, like toothpastes, are not meant to be swallowed, Fraundorf said accidentally ingesting a small amount is generally not dangerous. 'However, ingredients like fluoride and alcohol can cause stomach upset or toxicity in large amounts, especially in children,' she added. 'This is why mouthwash use should be supervised for kids under six, and only alcohol-free, fluoride-free options should be considered for young children who might swallow.'
Does mouthwash go bad?
Does mouthwash go bad?
According to Fraundorf, if you're using mouthwash daily, you'll likely finish the bottle well before expiration becomes an issue. 'The expiration date printed on the bottle is your best reference, as it reflects when active ingredients like fluoride or antimicrobials may begin to lose effectiveness and will vary based on the manufacturer and the specific type of mouthwash,' Fraundorf said. If there is no expiration date listed, Wei recommends replacing your mouthwash around three to four months after you open it.
To best preserve the ingredients, Fraundorf said to keep mouthwash stored in a cool, dry place with the cap tightly sealed. If you're buying mouthwashes for your household in bulk, Sands said unopened mouthwashes can last anywhere from two to three years if stored in this same manner.
While using expired mouthwash isn't usually harmful, Fraundorf said the ingredients can degrade over time, so a mouthwash may not provide the intended benefits if it's been open for a long period. Both Fraundorf and Rajpal added that if you notice any changes in the color, smell or taste of the mouthwash or see sediment forming and liquids separating, you should discard it.
Do I need to use a mouthwash?
Do I need to use a mouthwash?
Mouthwash is not a necessity for everyone to have in their routine. 'Individuals who brush twice daily with fluoride or nano-hydroxyapatite toothpaste and floss effectively may not need to include mouthwash,' Fraundorf said. 'Particularly if they are not dealing with dry mouth, gum disease or an elevated risk of cavities.'
However, for those trying to manage chronic bad breath, gum disease, enamel demineralization, orthodontic appliances or who are in post-surgical recovery, Fraundorf said adding a mouthwash into their daily routine might prove helpful.
