What do all dental plaques produce?

Dental plaques are biofilms formed by the accumulation of bacteria on tooth surfaces. One of the key characteristics of these plaques is their ability to produce acid as a byproduct of carbohydrate fermentation. When these bacteria metabolize sugars, they generate organic acids, primarily lactic acid, as a result.

The production of acid plays a significant role in the dental caries process. When acid is produced and remains in contact with the tooth enamel, it leads to demineralization of the enamel, which can eventually result in cavities. The presence of acid is a common outcome across all types of dental plaque, as it reflects the metabolic activity of the bacteria involved.

While caries, chelation, and mineralization are associated with the effects or consequences of plaque, it is the consistent and direct production of acid by the bacteria in dental plaque that is foundational to understanding why managing plaque is critical in dental health. The acids produced can demineralize the enamel and contribute to tooth decay if not properly managed.
