Maintaining oral hygiene is an essential part of overall health, and mouthwash has become a staple in many dental care routines. But dental discussions have raised a pressing question: Can mouthwash, particularly alcohol-based ones, increase your risk of cancer?

Why is Alcohol a Risk Factor For Oral Cancer and Other Health Issues?

Research suggests that alcohol-based mouthwashes may disrupt the delicate balance of the oral microbiome, the ecosystem of bacteria in your mouth. While these mouthwashes are indeed designed to address bacteria, they do not discriminate between the good bacteria, which are helpful for your oral health, and the bad bacteria, which can cause problems. This disruption in the balance of good and bad bacteria in your mouth may create an environment that fosters oral health issues.

Moreover, studies indicate a potential connection between mouthwash with alcohol and an increased risk of gum disease, oesophageal cancer, and colorectal cancer. Specific bacteria, such as Fusobacterium nucleatum and Streptococcus anginosus, have been identified as culprits in these conditions. Fusobacterium nucleatum has been linked to colorectal cancer, while Streptococcus anginosus is associated with oesophageal cancer. 

Although research is still ongoing, these findings raise valid concerns about the long-term use of alcohol-based mouthwashes.

Alcohol-Based vs. Alcohol-Free Mouthwash

Mouthwashes can be broadly categorised into alcohol-based and alcohol-free options, each with distinct characteristics. Alcohol-based mouthwashes contain ethanol which helps dissolve ingredients and kills bacteria. However, this comes at a cost. Alcohol will also eliminate the beneficial bacteria (not just the harmful ones), potentially upsetting the oral microbiome. As mentioned, alcohol can eliminate both harmful and beneficial bacteria, potentially upsetting the oral microbiome.

In contrast, alcohol-free mouthwash leverages a gentler approach. These formulations are designed to maintain a balanced oral environment by targeting harmful bacteria while preserving beneficial ones. Additionally, it does not cause the burning sensation or drying effect commonly associated with its alcohol-based counterparts.

Therefore, when shopping for dental products, look for an alcohol-free mouthwash that goes beyond simply freshening breath. 

Consider the Fluorinze Anti-bacterial Fluoride Mouth Rinse, formulated with tea tree oil and Thymol, which are natural antibacterial agents known for their ability to address bad breath and fight bacteria that contribute to plaque and cavities. The addition of Cetylpyridinium Chloride (CPC) and Xylitol further enhances its antibacterial power, while Potassium Chloride provides relief and protection against tooth sensitivity.

For individuals experiencing high levels of tooth decay and with significant tooth cavities, consider the Fluorinze Max High Fluoride Mouth Rinse. This rinse provides the maximum allowable fluoride (1400ppm) in a non-prescription product, making it readily accessible for cavity prevention. Moreover, it's enhanced with natural ingredients like Cinnamon, Chamomile, and Echinacea, offering a holistic approach to oral health and maximising the benefits of your daily rinse.

Is it Safe to Use Alcohol-Based Mouthwash?

The safety of alcohol-based mouthwash has been a subject of debate. While research on the link between alcohol-based mouthwash and cancer is ongoing, studies have shown a potential association, particularly with long-term use and high alcohol content.

Several factors may contribute to the risk associated with alcohol-based mouthwash, including:

  • Frequency and Duration of Use: Frequent and prolonged use of alcohol-based mouthwash may increase exposure to alcohol and its potential negative effects. As a matter of fact, a recent study revealed that the daily use of a popular mouthwash can have such unintended consequences. This was linked to an increase in certain types of bacteria in the mouth connected to serious health issues, such as periodontal diseases, and oesophagal and colorectal cancer. At the same time, the study found that this specific mouthwash also lowered Actinobacteria, a beneficial bacteria known for its role in regulating blood pressure and potential anti-cancer properties.
  • Alcohol Content: The amount of alcohol in a mouthwash can influence its safety, with higher amounts potentially posing a greater risk than those with lower concentrations.
  • Other Risk Factors: Smoking, excessive alcohol consumption, and an unhealthy diet can further increase the risk associated with alcohol-based mouthwash.

While these studies raise some interesting points, it's also important to remember that they have some limitations. More research is necessary before we can say for sure whether there's a direct connection between alcohol-based mouthwash and these health issues. Because of this uncertainty, it's best to consult with your dentist to discuss the potential risks and benefits of alcohol-based mouthwash based on your individual health needs and lifestyle.

Why Choose Mouthwash Without Alcohol?

Given the potential concerns surrounding alcohol-based mouthwashes, switching to an alcohol-free mouthwash can offer several benefits that support your oral health:

1. Maintains Saliva Production

Alcohol can dry out your mouth, reducing saliva's natural ability to wash away bacteria and neutralise acids. Alcohol-free mouthwash, on the other hand, helps maintain saliva production, keeping your mouth hydrated and healthy.

2. Gentler on Your Mouth

Alcohol-based mouthwash often causes a burning sensation, which can be uncomfortable for many users. Alcohol-free alternatives, however, are gentler, making them ideal for individuals with sensitive gums or teeth.

3. Safer for Dental Restorations

Alcohol can weaken certain dental restorations, such as fillings, crowns, or veneers, over time. However, given that alcohol-free mouthwash is less harsh, it can help preserve your dental work.

4. Beneficial Ingredients

Alcohol-free mouthwashes are formulated with active ingredients and natural antibacterials to address plaque, prevent cavities, and freshen your breath without the drying effects of alcohol.

For instance, the Defenze Antiseptic Fluoride Mouth Rinse, developed in collaboration with the National Dental Centre Singapore (NDCS), offers a unique and comprehensive approach to oral health. This proprietary, alcohol-free formula is fortified with CPC, Fluoride, Xylitol, and Zinc, delivering antiviral properties and addressing dental caries, bad breath, gum problems, plaque, and tartar build-up. Plus, this dermatologically-tested mouth rinse is enhanced with ten natural extracts, including cinnamon, echinacea, and tea tree oil, to deliver greater overall oral health benefits.

When is Mouthwash Necessary?

Mouthwash can play a key role in optimising your oral health, particularly in these situations.

  • After Brushing and Flossing: Even with diligent brushing and flossing, some food particles and bacteria can linger in hard-to-reach areas of your mouth. Mouthwash acts as a final rinse, reaching those nooks and crannies your toothbrush and floss might miss. However, it is important to note to not use mouthwash immediately after brushing as it washes away fluoride. Ir is recommended to wait at least 20 minutes after brushing, before using mouthwash.
  • Specific Oral Health Needs: If you suffer from gum disease, bad breath, or dry mouth, mouthwash can provide targeted relief and support.
  • Dentist Recommendation: Your dentist may recommend using mouthwash as part of a personalised treatment plan. This might be to address conditions like gingivitis, manage post-surgical healing, or provide additional protection for sensitive teeth.

Making the Right Choice: Mouthwash with Alcohol vs. Without

When choosing between alcohol-based and alcohol-free mouthwash, consider your individual needs and preferences. If you have worries about the potential risks associated with alcohol-based mouthwash, or if you experience any side effects from using alcohol-based products, you may want to opt for an alcohol-free alternative. 

However, it's always best to consult your dentist to discuss the most suitable option for your needs.
