The most likely pH range for healthy saliva

pH of Saliva:

• a. 5.5
• b. 6.5
• c. 7.5

The most likely pH range for healthy saliva is b. 6.5.

Saliva typically falls within a range of 6.2 to 7.6, with 6.7 being the average. While it can fluctuate slightly throughout the day and depending on your diet, a pH outside this range could indicate potential oral health concerns.

Here's a breakdown of the options:

- a. 5.5:

This is too acidic and could indicate a risk of tooth erosion and enamel demineralization.

- b. 6.5:

This is within the healthy range and suggests a balanced oral environment.

- c. 7.5:

This is slightly alkaline and might not be as effective in fighting off bacteria that can contribute to cavities.

It's important to remember that saliva pH is just one factor in oral health. If you're concerned about your oral health, it's always best to consult a dentist for a professional evaluation.
