Question

Explain the pH change as the cause of tooth decay.

Answer 1

Tooth decay cause:

1. Tooth decay begins when the pH of the mouth falls below 5.5.
2. Dentine and enamel are gradually weakened by tooth decay. When bacteria react with carbohydrates to produce acids, the enamel is first softened or demineralized. After eating, bacteria in the mouth produce acids by oxidizing the sugar and food particles there.
3. Food particles and a significant number of bacteria that stick to the teeth make up dental plaque. Plaque on the teeth prevents saliva from penetrating the tooth layer to neutralize the acid. Plaque is removed from the teeth after eating before the bacteria start creating acids.
4. The primary focus should be on reducing the number of bacteria in your mouth if you want to stop tooth decay. Brushing and flossing your teeth helps to prevent the accumulation of gummy bacteria (plaque).
5. Combining an antimicrobial mouthwash (such as Listerine or Scope) alongside brushing and flossing can assist to reduce oral bacteria.
