Does Mouthwash Whiten Teeth?

Whitening mouthwash has become a popular addition to oral care routines, promising a brighter smile with minimal effort and cost. But does it actually whiten your teeth? Yes, but only if it has the right ingredients, like hydrogen peroxide and others, which we’ll break down in this blog post. 

We’ll also explore the science behind whitening mouthwash, how to use it effectively and what to consider when choosing the best option for your needs.

How Does Whitening Mouthwash Work?

Whitening mouthwash contains tooth-bleaching agents that work through a chemical process known as oxidation. This process releases molecular oxygen, which penetrates the surface of your teeth and targets the larger pigment molecules responsible for discoloration, breaking them down into smaller particles. These particles then diffuse through the teeth, resulting in a lighter color. [1][2]

One of the most common oxidizing agents used in whitening mouthwash is hydrogen peroxide (HP)[3]. It has been shown to significantly lighten teeth and reduce yellow tones[4]. However, it does not significantly alter the enamel's inorganic mineral structure, which makes it less effective for deeper or intrinsic stains below the enamel surface. [5]

While whitening mouthwash effects are less significant than treatments like at-home tray bleaching gels[3], it provides a gentle, gradual lightening effect, making it ideal for daily use.

How To Use Whitening Mouthwash for the Best Results

Start by following the manufacturer's instructions to ensure you’re using the right amount and swishing for the appropriate amount of time. It’s important not to overuse mouthwash as it’s shown to cause damage to the cell structure and DNA of cheek cells [6].

Consistency is key, as whitening results build gradually with daily use. Studies suggest noticeable improvements in tooth color can take anywhere from 28 to 56 days of regular use[3], so patience pays off.

For best results, incorporate whitening mouthwash into a comprehensive oral care routine that includes oil pulling, brushing and flossing. Think of whitening mouthwash as a supporting player, breaking down surface stains[2] while brushing and flossing handle plaque and debris removal, respectively.

Choosing the Best Whitening Mouthwash

It’s important to look for a mouthwash containing hydrogen peroxide as it has been shown to more significantly lighten teeth and reduce yellow tones[5]. In comparison, non-hydrogen peroxide whitening solutions showed only slight improvements in color during the first week and quickly stopped being effective[7].

Fluoride is another common ingredient in many whitening mouthwashes because it helps strengthen enamel[8] and fight cavities[9]. However, its use isn’t without risks, especially when overused. Overexposure to fluoride can lead to dental fluorosis, which causes white spots or discoloration on teeth. 

Alcohol, or ethanol, is another ingredient commonly used in mouthwashes[10]. However, avoiding alcohol-based mouthwash is a smart choice for several reasons:

  • Adverse Effects on Oral Structures: Alcohol-containing mouthwashes have been linked to burning sensations, drying of the oral mucosa (inside of the mouth) and soft tissue irritation[10]. They can also soften composite filling materials, potentially compromising dental restorations[11].

  • Potential Cancer Risks: Alcohol-based rinses can significantly raise salivary levels of acetaldehyde, a carcinogenic byproduct of ethanol metabolism. Even at small systemic exposure levels, acetaldehyde concentrations in the mouth can cause DNA damage, which is associated with increased risks of oral cancer[12].

  • Tissue Healing and Sensitivity: These formulations can slow the healing process in surgical cases and are more likely to induce cell damage compared to alcohol-free alternatives[13].

For those seeking a more natural approach, products infused with essential oils offer additional benefits beyond whitening. For example, clove oil offers potent antimicrobial properties[14], making it effective against bacteria that cause bad breath[15] and gum issues[16]. Similarly, peppermint oil is effective against Streptococcus mutans, a primary bacterium involved in tooth decay and plaque formation. It also increases salivary flow, which helps combat halitosis by reducing dry mouth, a key contributor to bad breath[17]. Tea tree oil, also known for its antimicrobial effects[17], supports gum health by reducing plaque buildup[18]. 

When choosing a whitening mouthwash, look for ingredients that support fresh breath. Zinc ions are highly effective against volatile sulfur compounds (VSCs)[19], such as hydrogen sulfide and methyl mercaptan, which are the primary culprits behind bad breath[20]. By binding with these odor-causing compounds, zinc neutralizes their volatility and prevents the bacteria that produce them from thriving[21], providing long-lasting freshness and improved oral hygiene.

Advantages of Whitening Mouthwash 

Whitening mouthwash offers an easy way to enhance your daily routine without the need for major changes. It’s simple to add as a new step, and if you already use a mouthwash, swapping it out for a whitening option is even easier. It’s a convenient, time-saving alternative to professional treatments that can fit easily into your schedule, offering consistent results with regular use[3].

Affordability is another advantage. While professional whitening treatments averaged $508 in 2022, according to the American Academy of Cosmetic Dentistry, whitening mouthwashes are a fraction of the cost, usually costing between $5 – $15. 

For those seeking safe, effective whitening mouthwash, GuruNanda offers natural mouthwashes designed to promote happy gums and teeth without harmful chemicals. Our focus on natural ingredients ensures a product that fits effortlessly into any holistic oral care routine.

Maintaining a Bright Smile Beyond Mouthwash

Achieving a bright smile goes beyond just using a whitening mouthwash. Here are practical tips to keep your teeth looking their best:

  • Limit Staining Beverages: Cut back on coffee, tea and red wine, which cause staining[22]. If you do indulge, use a straw to minimize contact with your teeth. 

  • Prioritize Professional Cleanings: Schedule regular dental cleanings to remove stubborn stains and maintain oral health.

  • Build a Comprehensive Routine: Incorporate flossing, oil pulling and tongue scraping[23] into your daily oral care to target areas that brushing alone might miss.

  • Add an Alcohol-Free Mouthwash: Incorporate an essential oil-based, alcohol-free mouthwash to your flossing, oil pulling and brushing routine to reduce plaque, gingivitis and bleeding[24].

Remember, whitening mouthwash is most effective when paired with a holistic oral care routine that supports overall dental health.
