The Alkaline Mouthwash Advantage: Is It Better for Your Mouth?

Have you ever stopped to think about the ingredients in your mouthwash – other than its promise of fresh breath? If not, you might want to consider doing so.

Here’s the deal: some mouthwashes contain elements that disrupt pH levels in the mouth. Think of it like an uninvited guest showing up at your dinner party and throwing off the balance of food portions. Suddenly, some guests are left with less to enjoy, and the whole meal feels out of whack.

In the same way, an acidic mouthwash upsets the natural pH equilibrium responsible for keeping harmful microbes in check. An imbalanced oral environment may affect comfort, freshness, and the overall balance of the mouth.

Enter alkaline mouthwash. Unlike more acidic formulas, these products are designed to help maintain a balanced oral environment. This creates a healthy environment where beneficial bacteria can thrive. If you’re looking for a company leading the charge in innovative dental health, As an experienced oral care manufacturer, we support brands developing innovative mouthwash solutions, including pH-balanced formulas. They offer solutions that support oral microbiome health, including alkaline mouthwashes. Read on to learn the alkaline mouthwash advantage that makes it superior to conventional options.

pH Basics and Its Measurement

You probably recall the term pH from your high school chemistry class. But just in case it sounds foreign, potential hydrogen (pH) is the unit that measures an element’s alkalinity and acidity levels. This concentration is measured on a pH scale from 0 to 14. 0 represents the most acidic level, 14 represents the most alkaline, and a pH of 7 represents neutrality.

The Role of pH in Oral Health

Now, you’re probably wondering what all this pH discussion has to do with oral health. Well, the pH in your mouth (saliva’s pH) is key to oral health. Ideally, it should be maintained at a neutral level; between 6 and 7. Here are the potential effects of the extremities:

• Acidic pH: whenever you use an acidic product, it starts breaking down enamel- the protective layer of your teeth. The acid in these formulations weakens the enamel, causing it to wear down. The risk from this is that enamel erosion is permanent. And as you’ll see below, it comes with a host of other problems.  
• Alkaline pH: in comparison, dental products with a high pH are less abrasive on your enamel. They don’t weaken or soften it, which supports your oral health in the long term.

How Acidic Mouthwash Affects Dental Health

The food and drinks you consume directly impact your mouth’s pH. They can either increase or decrease saliva’s pH depending on their pH. And yes, this includes dental care products like mouthwash and toothpaste.

Despite being the hardest tissue in the body, tooth enamel is vulnerable to damage from acidic saliva. In fact, if salivary pH falls below 5.5, the enamel starts eroding. To make matters worse, the enamel does not contain any living cells- a factor that makes it irreparable. So, if it breaks or chips, the damage is permanent.

Once the enamel breaks down, the inner layer – dentin – is exposed. This layer is more sensitive, so your teeth might suddenly throw a fit when you try to enjoy your morning coffee or ice cream.   

Enamel erosion not only leaves you wincing at hot and cold foods, but also sets the stage for other dental issues like cavities and discoloration. The dentin that remains exposed is more susceptible to damage. This is why the risk of other dental problems increases, too.

Mouthwash Acidity  

Based on the above details, it’s clear why you should opt for an alkaline mouthwash. Such a product freshens your breath without altering oral pH. In other words, it kills the odor-causing bacteria without increasing acidity levels in your mouth. This chart shows some of the most popular varieties and their respective pH levels:

Acidic	pH
BreathRx Anti-Bacterial Mouth Rinse	6.21
ACT Restoring Fluoride Mouthwash	5.56
Chlorhexidine Alcohol-Free	5.1
Biotene Mouthwash	4.64
Listerine Antiseptic Mouthwash	4.88
Oral-B Antibacterial Rinse	4.62
Crest Pro-Health	4.27
Peroxyl Antiseptic Oral Cleanser	3.9
Tom’s of Maine Natural Wicked Fresh	3.89
Natural Dentist Anti-Gingivitis	3.3

Alkaline	pH
Therabreath Mouthwash Oral Rinse	8.2
ACT Anticavity Fluoride Rinse	7.95
Cepacol Mouthrinse	7.79
OraCare Mouthwash	7.55
Oxyfresh Mouthrinse	7.17
CloSYS Rinse	7.1
Biotene Oral Rinse for Dry Mouth	7.09

Neutral	pH
Colgate Optic White	6.95
CloSYS Alcohol Free Oral Rinse	6.85

pH values may vary by formulation and batch. The examples above are for educational comparison only.
As the chart above shows, most mouthwash products are acidic, increasing the risk of enamel erosion. This raises the question: how can you determine if a particular mouthwash is safe? Well, the key is to check the pH level.

Whenever possible, buy an alkaline mouthwash. If you must buy an acidic one, ensure its pH doesn’t fall below 5.5. Alternatively, examine the ingredient list of the mouthwash. Keep an eye out for harmful elements that lower saliva pH. Chlorhexidine (CHX) is a specialized active ingredient commonly used in professional oral care applications and should be used according to specific product instructions.

A study done by the British Dental Association shows that this element causes more harm than good. During the research, respondents rinsed their mouths twice daily for a week.

They first used a regular mouthwash before switching to the mouthwash with CHX. Results showed that the CHX mouthwash lowered saliva pH and its buffering capacity. These events lower saliva’s pH, creating the perfect breeding ground for harmful bacteria.

Here are a couple more factors to help you weed out undesirable mouthwash options:

• Products formulated by a private label mouthwash manufacturer
• Mouthwash products without an expiry date or expiration period
• Expired mouthwash
• Mouthwash lacking a batch number

Alkaline Mouthwash Benefits

Thinking of buying an alkaline mouthwash? Here are some potential benefits:

Helps Maintain Oral pH Balance

One of the greatest selling points of alkaline mouthwashes is their ability to restore pH balance. They neutralize the acids produced by food, drinks, and other bacteria, leading to a healthy environment for your teeth and gums.

Protects and Reinforces Tooth Enamel

A secondary benefit of restoring the pH equilibrium is the enhanced protection of the tooth enamel. As explained earlier, low oral pH (acidic substances) wear down the enamel, exposing the dentin. Thus, using an alkaline mouthwash counteracts this by neutralizing acids that would otherwise erode the enamel. This way, your teeth remain strong and resilient.

Freshens your Breath

An alkaline mouthwash does more than just revitalize your breath. It neutralizes the acids that fuel the odor-causing bacteria. This creates a fresh and clean environment where such bacteria can no longer thrive. Essentially, it provides long-lasting freshness.

Designed for a More Comfortable Mouthfeel

If your gums are inflamed, the last thing you want to use is an acidic mouthwash. This will only irritate the gums more, increasing discomfort and sensitivity.

Instead, consider an alkaline mouthwash. Not only is it gentler on the gums, but it also reduces acidity. This, in turn, promotes their natural healing.  

Supports Everyday Oral Health Protection

Using an alkaline oral rinse goes a long way in preventing tooth decay. As stated earlier, dental products with high acid levels wear down the enamel. This leaves the dentin exposed and more vulnerable to acids and bacteria. As these acids break down the dentin, they begin forming tiny holes in the teeth, ultimately causing tooth decay.

While alkaline formulations offer potential oral health benefits, achieving the right balance between pH, taste, and safety is critical in commercial production.
