Everyone wants a radiant smile that exudes confidence. Whether you’re preparing for a special occasion, an important meeting, or simply want to feel good about your oral health, having a whiter and healthier-looking smile can be a great boost. With over a billion dollars spent annually on over-the-counter whitening products in the US alone, it’s no wonder that DIY treatments have become increasingly popular.
In addition to whitening strips, toothpaste, toothbrushes, floss, and chewing gum, consumers now have the option of using whitening mouthwash as part of their daily oral care routine. Swishing with whitening mouthwash after brushing your teeth can be an easy way to add some extra whitening power to your routine.
While over-the-counter products won’t offer the same results as professional whitening, when used in conjunction with regular brushing, flossing, and common-sense preventative measures (such as avoiding smoking, limiting coffee and red wine intake, and practicing good oral hygiene), whitening mouthwashes can be very helpful in clearing up superficial stains on your tooth enamel and giving you a lustrous smile.
None of these DIY treatments will replace the effectiveness of professional whitening, but they can still play an important role in achieving that healthy-looking smile.
Factures to Consider in a Good Whitening Mouthwash
In a sea of seemingly endless options when it comes to whitening mouthwashes, it’s easy to feel overwhelmed and unsure about which one to trust. That’s why we’ve taken on the task of distilling the most important details for you, so you can make an informed decision and find a product that truly delivers. To guide our evaluation, we considered several key factors that set some mouthwashes apart from others.
Taste
While some individuals find standard mouthwashes too harsh, and whitening products often come with undesirable ingredients, we’ve curated a selection of mouthwashes that balance potency and palatability. Our criteria considered the chemical strength seen in products like Solimo Whitening Mouthwash, as well as ease of use, exemplified by ACT Anticavity + Whitening Rinse.
Notably, most mouthwashes contain alcohol, which can cause an unpleasant stinging sensation, with one exception being Listerine Healthy White Multi-Action Fluoride Mouth Rinse. In light of this, our selection exclusively features alcohol-free products.
Effectiveness
While it’s true that any whitening mouthwash containing reasonable percentages of hydrogen peroxide and/or sodium hexametaphosphate will eventually yield results, it’s crucial to temper your expectations. Products promising dramatic improvements in just days or weeks are likely overestimating their abilities due to the diluted nature of these products. A more realistic timeline is consistently using them for at least two to three months before noticing any significant difference.
However, we’ve identified certain mouthwashes with stronger formulas that can help accelerate the process – such as Listerine Healthy White Multi-Action Fluoride Mouth Rinse. It’s worth noting that those prone to tooth sensitivity may want to consider a slower approach using mouthwashes with lower hydrogen peroxide concentrations or opting for peroxide-free alternatives like Crest 3D Brilliance Mouthwash.
Top 9 Best Whitening Mouthwashes 2024
Best Overall Whitening Mouthwash Crest ProHealth Advanced Mouthwash with Extra Whitening
The Crest ProHealth Advanced Mouthwash with Extra Whitening boasts a well-rounded formula that addresses multiple oral health concerns. Its unique blend of hydrogen peroxide and sodium fluoride makes it an effective whitening mouthwash. Hydrogen peroxide not only lightens teeth but also exhibits antibacterial properties, leaving your breath fresh without the need for alcohol. This feature makes it an ideal choice for individuals with sensitive gums.
Sodium fluoride, on the other hand, strengthens tooth enamel, preventing cavities and addressing potential sensitivity issues caused by the hydrogen peroxide. Despite its robust formula, this mouthwash has a subtle wintergreen flavor that rinses easily without any burning sensation – more of a gentle tingle than a stinging feeling. This product tends to produce results faster than comparable products, especially when used in conjunction with regular brushing.
One drawback is the relatively small bottle size, which means you’ll need to replenish it frequently. However, purchasing a pack of four bottles can help alleviate this issue and provide a slight discount.
Best Whitening Mouthwash for Sensitive Teeth Crest 3D White Brilliance Mouthwash
When it comes to Crest 3D White Brilliance Mouthwash, one of the standout features is its ability to whiten teeth without relying on hydrogen peroxide. This makes it an excellent choice for individuals with sensitive teeth and gums who have experienced discomfort or pain when using peroxide-based mouthwashes.
The mouthwash achieves this through the use of active ingredients such as sodium hexametaphosphate, which serves as an advanced anti-tartar solution that not only removes superficial stains but also leaves a protective barrier on the teeth to prevent the absorption of chromogens throughout the day. While it may not be as effective as hydrogen peroxide, Crest stands behind its product with a moneyback guarantee in case users are not satisfied with the whitening results.
Additionally, sodium lauryl sulfate is present, acting both as a foaming agent for deep cleaning power and as a surfactant that cleans teeth with a similar hydrophobic action to soap. However, it’s worth noting that this product does not contain any fluoride, which means it won’t have a positive impact on reinforcing enamel or preventing cavities.
On the plus side, Crest 3D White Brilliance Mouthwash has been praised for its great taste, with an understated, natural-tasting minty flavor that lacks the chemical aftertaste often associated with hydrogen peroxide-based products. While it may not be perfect, this mouthwash is a solid option for those looking to whiten their teeth without compromising on comfort or taste.
Pros include being great for sensitive teeth and gums, offering a moneyback guarantee, having a great taste, and being alcohol-free. Cons include being less effective than hydrogen peroxide-based products and lacking fluoride.
Best Multipurpose Whitening Mouthwash Listerine Healthy White Multi-Action Fluoride Mouth Rinse
This multi-action mouthwash from Listerine boasts a potent blend of whitening, anticavity, and intense antibacterial ingredients. The key to its effectiveness lies in its high concentration of hydrogen peroxide, making it one of the fastest-acting and most effective whitening mouthwashes we’ve reviewed. While this formula does come with some trade-offs, such as tooth sensitivity concerns due to the fluoride content, the benefits of this product far outweigh the drawbacks for many users.
For instance, the fluoride in Listerine Healthy White Vibrant Multi-Action Fluoride Mouth Rinse helps protect and restore enamel, which can be particularly important for those who experience chronic dry mouth or sensitive gums. That being said, it’s worth noting that this mouthwash also contains 8% alcohol, which can make it an unpleasant experience for some users. If you’re willing to tolerate the temporary discomfort, however, the results will be well worth the effort.
On the flip side, those who prioritize a pleasant taste may want to look elsewhere, as Listerine’s Healthy White Vibrant Multi-Action Fluoride Mouth Rinse is not exactly known for its delightful flavor profile. Ultimately, this mouthwash strikes an impressive balance between its strengths and weaknesses, making it a worthwhile choice for many consumers.
Best Premium Whitening Mouthwash Supersmile Whitening Pre-Rinse
What sets Supersmile Whitening Pre-Rinse apart is its unique blend of clinically-formulated ingredients, designed to provide a comprehensive oral care experience. The mouthwash’s primary whitening agents are carbamide peroxide and sodium bicarbonate (baking soda), which work in tandem to effectively remove surface stains and whiten teeth.
While some products featuring abrasives have been discouraged due to their potential erosive impact on tooth enamel, the Supersmile formula strikes a balance with its low levels of sodium bicarbonate, making it suitable for short-term use.
Beyond these whitening agents, the mouthwash contains several additional ingredients that amplify its effects: Tetra Potassium Pyrophosphate serves as a thickening agent and tartar controller, preventing magnesium buildup on tooth enamel; Potassium bicarbonate helps desensitize nerves and enhance mineral density by regulating saliva pH levels; and Cetylpyridnium chloride acts as an antibacterial agent, reducing the spread of bacteria that can cause halitosis.
This synergistic blend boosts the overall whitening performance of the carbamide peroxide and sodium bicarbonate. It’s also noteworthy that Supersmile Pre-Rinse is free from various common allergens and irritants, including alcohol, gluten, sugars, artificial dyes, animal by-products, and fluoride, making it a suitable choice for individuals with sensitive teeth or gums. Although the product carries a premium price tag, its active ingredient profile justifies the cost.
Interestingly, the mouthwash is not flavored, which can result in a medicinal taste. Nevertheless, Supersmile Pre-Rinse’s pros outweigh its cons: effective whitening agents, useful secondary ingredients, antibacterial properties, and an alcohol-free formula.
Most Long-Lasting Results Colgate Optic White Whitening Mouthwash
Colgate Optic White’s strength lies in its potent hydrogen peroxide formula, combined with the brand’s patented ‘WhiteSeal’ technology. This unique blend enables lasting whiteness and prevents new stains from forming. The mouthwash contains a moderate 2% concentration of hydrogen peroxide, making it effective at removing stains, although it may be overpowering for those with sensitive teeth due to the absence of fluoride.
The formula also includes Acrylates/Methacryloylethyl Copolymer and PVM/MA Copolymer, which work together to enhance whiteness by controlling tartar formation and protecting enamel from dietary acid. While the mint flavor is not overpowering, it may be too bitter for some, a trade-off for the product’s effectiveness. Despite its limitations, Colgate Optic White has several advantages: a strong hydrogen peroxide formula, ‘WhiteSeal’ technology, and an alcohol-free composition.
However, it falls short in terms of fluoride content and taste.
Best Budget Pick Solimo Whitening Mouthwash (Amazon Brand)
We’re impressed by Solimo Whitening Mouthwash’s ability to deliver effective whitening results at an affordable price. At the heart of this product are two key active ingredients: 3% hydrogen peroxide, which provides a concentrated boost for faster results, and sodium hexametaphosphate, a mainstay in products like Crest 3D White Brilliance Mouthwash. While the absence of fluoride is a drawback, the mouthwash’s double-whitening punch makes up for it.
The subtle mint flavor is pleasant, but some may find the lingering aftertaste slightly sterile. What sets Solimo apart is its value-sized 946 ml (32 fl oz) bottles and Amazon’s satisfaction guarantee, offering a full refund if customers aren’t satisfied with the whitening effects. While it’s not perfect, Solimo’s pros – including being economical, alcohol-free, and backed by a moneyback guarantee – make it a solid choice for those looking to brighten their smile without breaking the bank.
Best Tasting Whitening Mouthwash Essential Oxygen Organic Brushing Rinse
One of the standout features of Essential Oxygen Organic Brushing Rinse is its exceptional taste. The mouthwash boasts an impressive 1.5% concentration of hydrogen peroxide, making it a powerful yet gentle bleaching agent that won’t compromise on effectiveness. Moreover, the inclusion of a liquid aloe vera solution provides additional benefits for oral health, including anti-inflammatory properties that can help soothe gums and potentially even prevent gingivitis.
While some users may miss the enamel-reinforcing and anticavity properties of fluoride, this mouthwash is a great option for those seeking an alcohol-free alternative. As the only USDA-certified organic, vegan, and cruelty-free product in its class, Essential Oxygen Organic Brushing Rinse prioritizes ethics alongside efficacy. With a natural flavor profile derived from peppermint, rosemary, eucalyptus, lemon peel, clove, and cinnamon essential oils, this mouthwash is a treat for the senses.
The main drawbacks are its fluoride-free composition and higher price point compared to other options on the market.
Most Gentle Formula ACT Anticavity + Whitening Rinse
ACT Anticavity + Whitening Rinse stands out for its gentle approach to oral care. While it contains a milder level of hydrogen peroxide, this mouthwash is designed to prevent cavities and tooth decay. The lower concentration of hydrogen peroxide may require a slightly longer wait for noticeable results, but it’s a great option for those with tooth sensitivity issues. Additionally, the presence of fluoride helps strengthen enamel and prevent new stains from forming.
Xylitol, a sugar-alcohol derived sweetener, also plays a crucial role in stabilizing the mouth’s pH balance, preventing erosion of enamel and promoting a healthy environment. The refreshing menthol taste is another plus, although some may find the artificial saccharin used to flavor the mouthwash slightly unpleasant.
Overall, ACT Anticavity + Whitening Rinse offers several benefits, including its gentler hydrogen peroxide formula, anticavity properties, pH balance stabilization, and lack of alcohol. However, it’s worth noting that the mouthwash’s relatively lower whitening power and artificial sweetener may be drawbacks for some users.
Best All-Natural Whitening Mouthwash Bee Naturals Whitening Pre-Brush Oral Rinse
Bee Naturals Whitening Pre-Brush Oral Rinse is a standout mouthwash that boasts an impressive combination of natural ingredients and effective whitening properties. With a potent 3% hydrogen peroxide content, this oral rinse is designed to tackle tough stains and leave your teeth looking brighter. The addition of xylitol helps protect tooth enamel by regulating the acidity of saliva, preventing corrosion and promoting healthy oral conditions.
However, it’s worth noting that this product does not contain fluoride. Beyond its whitening capabilities, Bee Naturals Whitening Pre-Brush Oral Rinse also incorporates bee propolis, a resin-like compound with anti-inflammatory and antimicrobial properties. This unique ingredient has been linked to soothing canker sores and gum inflammation, making it an attractive feature for those seeking natural relief from oral health issues.
What sets this mouthwash apart is its agreeable flavor profile, achieved through the use of peppermint and spearmint essential oils, as well as naturally occurring sweeteners like erythritol and stevia. While some whitening products can be overwhelming in their minty freshness, Bee Naturals Whitening Pre-Brush Oral Rinse strikes a pleasant balance.
While it’s true that this product carries a higher price tag than some of its competitors, the manufacturer is confident enough to offer a money-back guarantee for customers who aren’t satisfied with the results. As an added bonus, the absence of alcohol makes it a great option for those seeking a gentle, non-irritating oral care solution. Ultimately, Bee Naturals Whitening Pre-Brush Oral Rinse is a premium product that prioritizes natural ingredients and effective whitening capabilities.
Everything You Need to Know About Whitening Mouthwash
While the list of products provided should give you a solid foundation for making an informed decision about which whitening mouthwash best suits your needs, we’ve also included this FAQ section as a resource for those looking for further clarification on specific points. Here, we address any remaining questions or concerns you may have to ensure you’re equipped with all the information required to make the right choice.
How Do You Use Whitening Mouthwash?
While it may seem trivial, many individuals overcompensate when it comes to using mouthwash and the duration of their rinsing routine. In reality, most products require only a couple teaspoons of mouthwash, and you shouldn’t spend more than 60-90 seconds swishing. Contrary to what some might assume, excessive mouthwash usage or prolonged swishing can have negative consequences on tooth enamel, emphasizing the importance of moderation.
How Do My Teeth Get Stained in the First Place?
Teeth are remarkable structures composed of multiple layers, each with unique properties. For our purposes, we’ll focus on the top two layers: enamel and dentin. Enamel is the hardest substance in the human body, primarily consisting of calcium phosphate molecules called hydroxyapatite that form a crystal structure. Despite its remarkable strength and seeming impenetrability, enamel is porous at the microscopic level.
The layer of dentin beneath the enamel is also composed of hydroxyapatite, but with significantly smaller crystal molecules, making it softer and more porous than enamel. A thin film of salivary proteins, carbohydrates, and fats, known as the pellicle film, constantly coats the top layer of enamel on your teeth. When you consume substances like coffee, red wine, or smoke cigarettes, intensely pigmented molecules called chromogens are absorbed into this film and deposited onto the enamel.
These chromogens gradually seep into the microscopic pores of the enamel, causing stains to form. It’s essential to note that whitening mouthwashes are only effective in eliminating surface-level stains. Once chromogens penetrate into the underlying dentin layer, professional teeth whitening at a dentist is necessary.
Factors beyond food and drink can also contribute to tooth discoloration: age plays a significant role as enamel wears down over time, revealing the naturally yellower dentin beneath, while physical trauma and certain medications can also alter tooth color. Unfortunately, whitening mouthwashes have no impact on baseline shade if discoloration is caused by age, injury, or medication side effects, nor do they affect caps, veneers, crowns, or white-colored fillings.
What’s Different About the Professional Whitening Process?
Dentists employ hydrogen peroxide as a teeth whitening agent, but they utilize significantly higher concentrations and apply it for an extremely brief period. To counterbalance the potential enamel erosion caused by bleaching, they often follow up with a fluoride treatment that remineralizes the enamel. During this procedure, the gums and tongue are safeguarded using a rubber dam or water-soaked gauze.
While at-home use of high-concentration hydrogen peroxide can be detrimental to oral health, exposing you to risks such as enamel wear, collagen damage in dentin, and nerve irritation within teeth. Fortunately, every product listed features a moderate level of hydrogen peroxide that, when used properly, does not pose this risk.
How Does Whitening Mouthwash Work?
When selecting a mouthwash for teeth whitening, we’ve zeroed in on products containing hydrogen peroxide and/or sodium hexametaphosphate as their active ingredients. These compounds have been clinically proven to whiten teeth effectively. Hydrogen peroxide, being a potent bleaching agent, penetrates the enamel and undergoes oxidation to break down embedded chromogens into smaller molecules.
This process reduces the visibility of superficial stains by diluting the inherent discoloration in your teeth. Sodium hexametaphosphate operates differently, displaying a strong affinity for calcium hydroxyapatite in tooth enamel. It alters the binding properties of chromogens, making it efficient at removing extrinsic stains and preventing new ones from forming.
Crucially, both hydrogen peroxide and sodium hexametaphosphate-based mouthwashes are only effective against superficial stains on the outer layer of tooth enamel.
What Is the Best Way to Prevent Stains?
To prevent teeth stains from occurring in the first place, it’s crucial to limit or avoid consuming foods and drinks rich in chromogens like coffee, tea, dark berries, and tobacco products. When drinking pigmented beverages, use a straw to minimize direct contact with your teeth. Additionally, reduce your sugar intake as the metabolization of sugars by saliva can erode enamel over time, while also fostering the growth of streptococcus mutans bacteria linked to tooth decay.
Regular brushing and flossing twice daily, alongside bi-annual dentist cleanings, are essential precautions. When possible, use a fluoride-containing toothpaste that continuously remineralizes your enamel and prevents chromogens from seeping into dentin. Your enamel’s hydroxyapatite can also self-repair through dietary calcium conversion, but ensure you also consume adequate vitamin D and phosphorous for proper absorption.
How Effective Is Whitening Mouthwash Compared to Whitening Toothpastes and Whitening Strips?
Whitening strips are widely considered the most effective over-the-counter whitening products, thanks to their higher concentration of bleaching agents and longer application time, which can range from five minutes to an entire hour. However, this increased potency also means they carry a higher risk of enamel damage and tooth sensitivity if used incorrectly. On the other hand, whitening toothpastes are able to effectively remove extrinsic stains through mechanical brushing action.
To maximize their effectiveness, look for peroxide-based toothpastes and avoid those that rely on abrasives like hydrated silica, sodium bicarbonate, or activated charcoal. In contrast, whitening mouthwashes tend to have a limited impact due to their diluted nature, the instability of hydrogen peroxide in an aqueous solution, and the brief duration of the rinsing process.
Whitening Mouthwashes Are a Bright Spot in Your Dental Routine
While whitening mouthwash is not a replacement for consistent oral hygiene practices like brushing, flossing, and regular dental visits, it can be a useful addition to your daily routine. When used in conjunction with these habits, whitening mouthwashes can help enhance the vibrancy of your smile.
