Question

what is cause of decay of tooth ? what is the ph of mouth required ​

Answer 1

Answer:

Tooth decay can occur when the pH level in the mouth is 5.5. ... When we consume acidic foods and drinks, the pH within the mouth decreases and can cause the pH in the dental plaque to fall rapidly below 5.0. This happens through the production of acids as the bacteria metabolize the ingested nutrients.
