Understanding Oral pH (Why It Matters)

The pH scale, ranging from 0 to 14, measures how acidic or alkaline a solution is. A neutral pH is 7, anything below that is considered acidic, and anything above is alkaline.

Need Dental Advice? Ask Dr. Hannan a Question!

Our mouth’s natural pH hovers around 6.5 to 7.5, leaning towards the neutral side. However, the foods we consume, especially sugary and processed foods, can dramatically lower the oral pH, creating an acidic environment.

Why is this a concern? An acidic oral environment is a breeding ground for harmful bacteria.

These bacteria thrive in low pH levels, leading to cavities, gum disease, and tooth erosion. By maintaining a balanced oral pH, we not only keep our teeth and gums healthy but also prevent bad breath and ensure overall oral hygiene.

Benefits of Alkaline Mouthwash Over Traditional Options

While traditional mouthwashes are effective in killing bacteria and freshening breath, they might not address the issue of oral acidity. This is where alkaline mouthwashes step in.

Common Benefits

  • Neutralizing Acidity: Alkaline mouthwashes are designed to raise the pH level in the mouth, neutralizing harmful acids that can damage tooth enamel and irritate the gums.
  • Natural Ingredients: Many alkaline mouthwashes come with natural ingredients like aloe vera, chamomile, and baking soda, which not only neutralize acids but also soothe the mouth and reduce inflammation.
  • Long-Lasting Protection: With their ability to balance the pH, alkaline mouthwashes provide prolonged protection against harmful bacteria, ensuring a healthier oral environment.

Criteria for Choosing the Right Alkaline Mouthwash

Before you rush to add an alkaline mouthwash to your shopping list, consider these criteria to ensure you’re making the right choice.

Key Features

  • pH Level: Ideally, you’d want a mouthwash with a pH level closer to 8 or 9. This ensures the effective neutralization of oral acids.
  • Ingredient List: Opt for mouthwashes with natural ingredients. Avoid those with alcohol, which can dry out the mouth, or any other harsh chemicals.
  • Taste and Feel: Since you’ll be using it daily, ensure the mouthwash has a pleasant taste and doesn’t leave an uncomfortable residue or burning sensation.
  • Reviews and Recommendations: Always check user reviews and possibly get recommendations from your dentist. They can guide you toward a product that suits your specific needs.

Top 5 Best Alkaline Mouthwash

Given the significance of maintaining a balanced oral pH, selecting an effective mouthwash becomes imperative. Transitioning beyond just freshening breath, the right mouthwash can be pivotal in ensuring optimal oral health.

Frequently Asked Questions (FAQ)


No, an alkaline mouthwash is a supplemental oral care product and should not replace regular tooth brushing and flossing. Brushing removes food particles and plaque from the teeth's surface, while flossing dislodges debris from between the teeth. An alkaline mouthwash complements these routines by balancing oral pH and reducing bacteria but cannot substitute the mechanical cleaning provided by brushing and flossing.

An overly acidic oral environment can lead to symptoms such as tooth sensitivity, frequent cavities, bad breath, and gum irritation or inflammation. If unchecked over time, it can also result in tooth enamel erosion, making teeth more susceptible to staining and decay.

Naturally maintaining an alkaline environment involves a combination of dietary and oral care practices. Consuming a balanced diet with plenty of leafy greens, fresh vegetables, and reducing acidic or sugary foods and beverages can help. Drinking water frequently, especially after meals, can also assist in neutralizing acids. Regular oral hygiene practices, including brushing, flossing, and occasional use of baking soda as a mild abrasive, can also promote an alkaline setting.

My Experience & Expertise

As a dentist, I’ve seen firsthand the profound impact our daily choices can have on oral health. The mouth is a dynamic ecosystem, constantly influenced by what we eat, drink, and adopt care routines.

The emphasis on alkaline mouthwashes underscores a fundamental truth in dentistry: the delicate balance of our oral environment is paramount.

The acid-alkaline balance, often overlooked, plays a pivotal role in safeguarding our teeth and gums from potential threats. While the array of products in the market can be overwhelming, navigating these choices with knowledge and discernment is essential.

A mouthwash isn’t just about freshness; it’s a tool, a protective shield that can enhance the natural defenses of our oral cavity.
