D) Within the tooth's root canal

Answer 1

Tooth decay is caused by bacteria in plaque, and it can accumulate on the enamel surface of the tooth.

Step-by-step explanation:

Tooth decay, also known as dental caries or cavities, is caused by the activity of bacteria on the teeth. When clean teeth come into contact with saliva, a layer of proteins and carbohydrates forms, attracting bacteria and forming a biofilm called plaque. The most common cariogenic species in plaque is Streptococcus mutans. These bacteria feed on sugars in the mouth and produce acids that dissolve the enamel of the tooth, leading to decay. The plaque can accumulate on the enamel surface, causing decay on the crown of the tooth.
