Key Concepts

Biofilm Formation

This concept refers to the accumulation of bacteria on tooth surfaces in the form of dental plaque. The biofilm acts as a protective environment for bacteria, allowing them to adhere to the tooth and interact efficiently with dietary components.

Bacterial Metabolism of Sugars

Bacteria in the dental plaque metabolize sugars obtained from food. Through fermentation processes, these bacteria convert sugars into acids, creating an environment that is detrimental to the structural integrity of the teeth.

Acid Production

The fermentation of sugars by oral bacteria leads to the production of acids. This acid production is a key factor that initiates the process of dental caries, as it lowers the pH in the mouth and starts the demineralization of the tooth enamel.

Enamel Demineralization

Enamel demineralization occurs when the acids produced by bacterial metabolism gradually dissolve the mineral content of the tooth's outer layer. This process compromises the hardness and integrity of the enamel, setting the stage for the formation of cavities.
