Question

The presence of a base causes tooth decay. True or false?

• A. True
• B. False

Answer 1

The correct option is B False

Tooth decay:

1. Tooth decay results in the gradual softening and degradation of the enamel and dentine.
2. Tooth decay starts when bacteria that grow overnight start acting on sugars from the teeth, and secrete various acids.
3. These acids soften or demineralize the enamel.
4. Tooth decay starts as the pH of the mouth goes under 5.5.
5. Thus, bases do not decay the tooth but acids do.

Thus, the given statement is false.
