What is the resting pH of the mouth?

The resting pH of the mouth typically ranges between 6.0 and 7.0, with a commonly accepted average being around 6.7. This slightly acidic to neutral pH level is essential for maintaining oral health, as it helps to control the growth of bacteria and protects against tooth decay. A resting pH of 6.0, while slightly on the lower end, reflects a balance that supports the overall environment of the oral cavity.

When the pH drops below 5.5, it can lead to demineralization of tooth enamel and increase the risk of caries. It is important to maintain a healthy pH balance through appropriate oral hygiene practices and dietary choices to prevent dental problems. The correct answer reflects the typical resting pH that you would expect to find in a healthy mouth, emphasizing the importance of maintaining this balance for oral health.
