The pH of teeth is not a fixed value but is dependent on the surrounding environment. The enamel of teeth is generally considered to be slightly acidic, with a pH around 5.5. However, this can fluctuate based on factors like diet and saliva pH.
- Neutral pH: The neutral pH level is 7.0, with values below 7 considered acidic and values above 7 considered alkaline (basic).
- Acidic Foods: Consuming acidic foods and drinks can lower the pH of saliva, making it more acidic.
- Tooth Decay: When the pH level in the mouth falls below 5.5 for extended periods, it can create an environment conducive to the growth of cavity-causing bacteria, leading to tooth decay.
- Saliva pH: A healthy saliva pH typically ranges from 6.2 to 7.6, playing a crucial role in maintaining oral health.
It is important to note that the pH of the mouth is constantly fluctuating, and maintaining a balanced pH is essential for protecting tooth enamel and preventing decay.
