Question

what value of PH in the mouth leads to tooth decay why​

Answer 1

Answer:

Tooth decay can occur when the value of PH in the mouth is 5.5. For reference, the neutral level is 7.0. When we consume acidic foods and drinks, the PH level in the mouth decreases and can cause the PH level in the dental plaque to fall rapidly below 5.0.
