Bacteria are necessary to cause dental caries. They adhere to the tooth surface with the help of plaque and use the carbohydrates in food (especially sucrose) to polymerise and produce highly viscous dextrans to form a plaque matrix on the one hand, and to produce acid to demineralise the tooth and cause caries on the other.
Streptococcus mutans is the most damaging of these caries-causing bacteria.
Oral probiotics are of great importance in the prevention of dental caries through their ability to inhibit the growth of cariogenic bacteria in the mouth by colonising or producing metabolites in the mouth.
