Mention the pH value below which tooth decay begins. How this fall below this value?
Explain the ill effect of the acidic medium in the mouth. How can this be prevented?
Answers
Answer:
below 5.5 pH
After taking meals due to some enzymes that become active the pH decreases
Due to this the problem of tooth decay arises
This decays the calcium phosphate layer of our teeth
To prevent this one should brush his or her teeth after taking meals
As the toothpaste and tooth powder contain bases they neutralize the acidic medium of the mouth
HOPE IT MAY BE HELPFUL

Answer:
pH value of which tooth decay is less than 5.5. After taking meals due to some enzyme that become actives the pH value.
Bacteria present in the mouth produces acids by degradation of sugar and food particles remaining in the mouth. It can be prevented by using toothpaste which is generally basic to neutralize excess acid.
