In recent years, many people have been making the switch to alcohol-free mouthwashes due to growing awareness of how alcohol can disrupt the delicate balance of the mouth's microbiome. Alcohol in mouthwash has been shown to kill not only harmful bacteria but also the beneficial ones essential for maintaining oral health. As a result, xylitol-based mouthwashes have gained popularity as a gentler alternative that supports oral hygiene while preserving the beneficial bacteria.
Therabreath is a popular alcohol-free mouthwash marketed as a healthier alternative to traditional options, boasting the use of xylitol for oral health benefits. However, one ingredient in Therabreath—sodium chlorite—raises concerns due to its potential to form toxic byproducts under certain conditions. Understanding the science behind sodium chlorite and its risks is crucial for informed consumer choices.
At first glance, sodium chlorite and sodium chloride may sound similar, but they are chemically distinct substances with vastly different properties:
Sodium Chloride (NaCl): Common table salt, an essential nutrient that supports various physiological functions in the body. It is highly stable and poses no significant risks under normal conditions.
Sodium Chlorite (NaClO₂): An oxidizing agent used in industrial processes such as bleaching and water purification. It is far more reactive than sodium chloride and can participate in chemical reactions that produce harmful byproducts.
Sodium chlorite is relatively stable on its own, but when it comes into contact with acidic substances, it can react to produce chlorine dioxide gas. This gas, in turn, can degrade into toxic chlorine gas (Cl₂), which poses significant health risks. Here’s the reaction pathway:
Sodium Chlorite + Acid: NaClO₂ + HCl → ClO₂ (Chlorine Dioxide) + NaCl
Degradation of Chlorine Dioxide: 2ClO₂ → Cl₂ (Chlorine Gas) + O₂
Chlorine gas is highly toxic and can cause irritation of the eyes, nose, and throat at low concentrations, while higher exposures can result in respiratory distress and other severe health issues.
The acidic environment of the mouth, especially after consuming acidic foods or beverages, can potentially trigger the reactions described above. While manufacturers like Therabreath likely ensure that their formulations minimize these risks, the presence of sodium chlorite still warrants caution, especially for individuals with oral conditions that could amplify acidity.
Irritation or sensitivity in the mouth or throat.
Theoretical risk of toxic byproduct formation if mixed with other acidic oral care products.
Environmental concerns associated with the disposal of products containing oxidizing agents.
For those looking for effective yet safer mouthwash options, consider the following:
Xylitol-Based Mouthwashes Without Sodium Chlorite:
Look for formulations that use xylitol for cavity prevention but avoid oxidizing agents like sodium chlorite.
Example: Biotène Dry Mouth Oral Rinse.
Natural Mouthwashes:
Products with natural antimicrobial ingredients like tea tree oil, aloe vera, or peppermint oil.
Example: Tom’s of Maine Natural Wicked Fresh Mouthwash, which is formulated with zinc that is claimed to naturally neutralize odors.
Hydrogen Peroxide-Based Mouthwashes:
A mild and effective alternative for whitening and antibacterial purposes.
Example: Colgate Peroxyl Mouth Sore Rinse.
DIY Mouthwash:
Mix a simple solution of baking soda and water for neutralizing acidity and freshening breath.
While Therabreath and similar products may offer benefits as alcohol-free mouthwashes, the inclusion of sodium chlorite warrants closer scrutiny due to its potential to form harmful byproducts. By choosing safer alternatives or consulting with a dental professional, consumers can maintain their oral health without unnecessary risks. Remember, informed decisions pave the way for a healthier smile!
