Balancing your mouth’s pH levels
Many people try to achieve balance between work, life, family and friends. But have you considered that the pH in your mouth needs balance, too?
Why pH matters
The pH scale measures how acidic or alkaline a substance is. The scale goes from 0 to 14, with 7 representing neutral levels. The lower the number, the more acidic. The higher the number, the more alkaline. Meanwhile, plain water has a pH of 7.
The normal pH of saliva is between 6.7 and 7.4, meaning that it’s relatively neutral. Multiple factors can increase or decrease the pH level of saliva, however, and those changes in pH can harm your oral health.
Factors that increase saliva acidity
While saliva with a high pH can be a sign of other health issues, it’s low or acidic pH that’s most commonly associated with oral health problems. Here are four common causes of saliva acidity.
pH and oral health
Your tooth enamel is the hardest substance in your body, but it’s still no match for extreme acidity. When the pH level of saliva goes below 5.5, the enamel protecting your teeth loses minerals and starts weakening. Enamel can’t heal itself or grow back, so the damage done by high acidity levels can be long term. Brushing with fluoride toothpaste and drinking fluoridated water can help repair damaged enamel.
The erosion of enamel can lead to:
