Acidogenic Oral Bacteria Overview

Acidogenic oral bacteria are microorganisms within the oral cavity that metabolize dietary carbohydrates into organic acids, leading to a decrease in pH at the tooth surface and contributing to dental caries. Key species include Streptococcus mutans, Lactobacillus spp., and Bifidobacterium spp. Targeting these bacteria or modulating their activity is a central strategy for preventing or managing dental caries.

Mechanism of Action

Inhibition of bacterial growth and metabolism; disruption of biofilm formation; reduction of acid production

Biological Functions

Fermentation of dietary carbohydrates
Production of organic acids
Biofilm formation
Nutrient acquisition

Disease Associations
