Why are scientists studying vaccines to prevent cavities?

Scientists are investigating vaccines and other methods to influence the bacterial composition of the oral cavity because dental caries (tooth decay) is an infectious disease driven by specific microorganisms.12

The primary culprit in this process is the bacterium Streptococcus mutans, which resides in dental plaque. These bacteria metabolize ingested sugars and fermentable carbohydrates, producing acids that dissolve enamel and lead to cavity formation. By targeting the bacterial population responsible for this acid production, researchers aim to develop new strategies for the prevention and treatment of decay beyond traditional methods like dietary changes, fluoride use, and dental sealants.21

Ultimately, the goal is to shift the oral microbiome toward a state that does not facilitate the destruction of tooth structure.1
