BlogAlkaline Water & Dental Health: Can It Improve Oral Hygiene?

Over the past few years, the health and wellness community has grown interested in alkaline water and its benefits. While benefits such as reduced high blood pressure, balanced pH levels and enhanced immune system are some of the more commonly known benefits, one other area of exploration that has gained attention is its potential impact on oral health. The many benefits of alkaline water have also led to the rise of the popularity of alkaline water purifiers in Singapore.

Below, we delve into the science behind alkaline water and its potential effects on dental health.

What is Alkaline water?

To understand the relationship between alkaline water and dental health, it is essential to first understand what alkaline water is. Alkaline water typically has a pH level of 8 to 9.5, which is higher than regular tap water. This higher pH is attributed to the presence of minerals such as calcium, potassium, and magnesium.

Maintaining an optimal pH balance in the body is crucial for overall health, including oral health. The pH scale ranges from 0 to 14, with 7 being neutral. Anything below 7 is typically considered as acidic, while levels above 7 are alkaline. The mouth tends to be slightly acidic, with a pH ranging from 6.2 to 7.0. Alkaline water’s higher pH could potentially help neutralise acidity, creating an environment less conducive to the growth of harmful bacteria.

Can alkaline water improve dental health?

1. Antioxidant properties and gum health

An aspect of alkaline water explored by researchers that can potentially help in improving dental health is its antioxidant properties. Antioxidants help combat oxidative stress, which plays a role in various health conditions, including gum disease. While studies specifically linking alkaline water to improved gum health are limited, the antioxidants present in alkaline water may contribute to an overall reduction in inflammation and oxidative damage in the oral cavity.

2. Hydration and saliva production

Proper hydration is crucial for maintaining good oral health. Alkaline water, with its enhanced pH and mineral content, may encourage individuals to stay adequately hydrated. Furthermore, staying hydrated is known to stimulate saliva production. Saliva plays a crucial role in neutralising acids, washing away food particles, and promoting remineralisation of tooth enamel. Alkaline water could indirectly support oral health by promoting hydration and saliva production.

3. The role of pH in enamel protection

Researchers have explored how alkaline water’s pH levels may play a crucial role in safeguarding tooth enamel. Enamel erosion, triggered by acidic foods and beverages, can result in tooth sensitivity and heightened vulnerability to cavities. Alkaline water, with its elevated pH, aids in neutralising acidic conditions in the mouth, creating an environment less conducive to enamel erosion. Notably, acidic pH levels lead to demineralisation, a process starting at a pH of about 5.5, causing tooth sensitivity and decay. This underscores the importance of understanding how alkaline water can counteract demineralisation, but further comprehensive research is necessary for a complete assessment of its impact on dental health.

The importance of a holistic approach

Although drinking alkaline water can play a part in improving dental health, it is important to remember that achieving proper oral hygiene involves a combination of factors, including a balanced diet, proper oral care routines, and regular dental check-ups. Alkaline water, if included in a holistic approach, may offer additional support to overall oral health. However, it should not be viewed as a standalone solution. Maintaining good oral hygiene habits, such as regular brushing, flossing, and professional dental cleanings is still essential.


The connection between alkaline water and dental health is an exciting topic that warrants further research. While some evidence suggests potential benefits, it is essential to approach these findings cautiously. As research in this field continues, individuals are encouraged to stay informed and consult with dental professionals for personalised advice on maintaining a healthy smile.
