What is saliva pH? And How it affects your Dental health.

What is saliva pH? And How it affects your Dental health.

The pH stands for potential hydrogen, indicating the acidity or alkalinity level of a substance.

pH 0 is the most acidic, pH 7 is neutral (pure water), and pH 14 is the most alkaline.

Saliva’s pH range is normally between 6.2 and 7.6.

The pH of saliva can be influenced by food, drinks, and age.

Carbohydrates in food can be broken down by mouth bacteria, leading to the release of acids that lower saliva’s pH.

Why is pH balance important?

The human body needs a pH close to water (neutral) for proper functioning.

Too much acid in the blood (low pH) can lead to metabolic acidosis, associated with conditions like high blood pressure, kidney disease, and diabetes.

Too much alkaline in the blood (high pH) can lead to metabolic alkalosis, associated with adrenal disease and alcohol abuse.

Importance of Saliva pH:

Maintaining a balanced pH in the mouth is essential for oral health.

Drinking acidic beverages can lower saliva pH below 5.5, leading to demineralization of tooth enamel.

Acidic saliva, your teeth can suffer from acid erosion, leading to enamel loss, tooth decay, and cavities. 

Thin enamel can exposed dentin and cause discomfort with hot, cold, or sugary drinks. since tooth enamel can’t grow back, the damage is permanent.

But a high pH level in your mouth can increase bone density and enamel strength.

Examples of acidic foods and drinks include soft drinks (pH 3), white wine (pH 4), American cheese (pH 5), and cherries (pH 4).

You can diagnose that your saliva pH level is imbalanced because of:

  • Persistent bad breath
  • Sensitivity to hot or cold food or beverages
  • Tooth cavities
  • Yellow discoloration due to enamel erosion

Why is the pH saliva test important?

Digestive Health: medicine practitioners claim that an acidic pH in saliva may be indicative of poor digestion, imbalanced gut flora, or other digestive issues. They may use the test to assess whether certain dietary changes or supplements could be beneficial.

Acid Reflux: People with symptoms of acid reflux or gastroesophageal reflux disease (GERD) use the test as a non-invasive way to monitor changes in their saliva’s acidity, possibly to gain information into the severity of their condition.

Alkaline Diet Monitoring: researchers proved that consuming more alkaline foods can improve overall health and prevent certain diseases.

The pH saliva test is used to assess whether this diet is making body more alkaline or not.

Oral Health: Saliva pH can affect oral health. For example, a lower pH can contribute to tooth decay and other oral issues. Dental professionals use pH testing as part of assessing a patient’s oral health.

Method to balance Saliva pH:

  • Saliva pH can be tested to monitor oral health.
  • Avoid excessive consumption of acidic foods and drinks.
  • Consume alkaline-rich foods to help balance pH.
  • Adding beans to your diet such as Lima beans, navy beans, soybeans, and sesame seeds are all great as they are alkaline in nature. 
  • Practice good oral hygiene to minimize the impact of acidic substances.
  • Rinse your mouth with water after you eat or drink.
  • Use an Alkaline water filtration system and Drink clean purified alkaline mineral-rich, antioxidant water

Alkaline water emerges as a good alternative to maintain pH balance of saliva due to its superior mineral content, antioxidant properties, and cleanliness.

Alkaline water ionizers are devices that raise the pH level of water, making it more alkaline. Ionized water undergoes electrolysis which separates water into acidic and alkaline components.

As drinking alkaline water can help balance the pH levels in the body, including saliva.

Ionized water can neutralize excess acidity in the body and create a more alkaline environment in your body including saliva.

An Alkaline Water Purifier, such as Life Ionizers Alkaline Water Purifier, can be an excellent asset. It filters out harmful substances and replenishes vital minerals.

You can see the high-quality system by Clicking this link of water ionizers Alkaline Water Filtration systems.


In conclusion, If your pH levels are 7.5 or higher, you can help remineralize the enamel and fight against cavity-causing bacteria. Regular consumption of ionized water, which is often alkaline mineral rich, can restore the pH balance of the body including saliva. 

As alkaline water neutralizes excess acids in the body, it restores a more alkaline state.
