Tooth Decay Explained: Insights from NIDCR

According to NIDCR, tooth decay develops through a gradual process. Dental plaque contains bacteria that convert sugars and starches into acids. These acids repeatedly attack enamel, leading to mineral loss over time.

If remineralization does not keep pace with acid attacks, early enamel damage can progress into cavitation. Once a cavity forms, bacteria can move deeper toward dentin and pulp, increasing the chance of pain, infection, and more complex treatment.

NIDCR prevention principles include fluoride exposure, effective plaque control, and reducing the frequency of sugary intake. In practical terms, this means fluoride toothpaste, daily interdental cleaning, and avoiding all-day sipping on sweet drinks.

Early intervention is critical. Small lesions are easier to manage than deep decay. Regular checkups and radiographs, when indicated, improve the chance of detecting disease before major structural damage occurs.
