Final answer:
Dental caries cannot occur without sugar consumption.
Step-by-step explanation:
Dental caries, also known as tooth decay or cavities, cannot occur without sugar consumption. When sugar is broken down by bacteria in the mouth, acids are produced that dissolve the minerals of the tooth, leading to decay. Other factors such as fluoride application, proper oral hygiene, and saliva production can help prevent tooth decay, but sugar consumption is the main cause.
