...causes dental carries? i want to know what r the bacteria that cause the dental carries and how it causes it in details

Jonny Q

Mutans streptococcus - the main bacterium causing dental caries.
# 1. The oral bacteria responsible for dental caries belong to the streptococcus mutans and lactobacilli groups of bacteria.
# 2. These bacteria, which cause dental caries, are able to metabolize sugar, produce a destructive lactic acid, and produce a sticky dental plaque. This destructive acid dissolves the mineral structure (hydroxyapatite crystals) of teeth. If the tooth mineral continues to be lost because of acid attack, the surface of the enamel will eventually be cavitated, producing a cavity.
# 3. The bacteria which cause caries are usually "passed on" from mother to infant, as early a 10 months of age. The danger of infecting an infant's teeth is increased if the mother already has the caries disease herself.
# 4. Children who frequently consume refined sugar products, such as candy and soft drinks, have a high risk of developing dental caries. Sucrose, a type of sugar, is therefore an important contributor to dental caries
# 5. The newly erupted teeth of infants are the most susceptible to caries because they are not yet fully hardened (calcified). Calcium and phosphate in the saliva help fight dental caries by gradually "maturing" the tooth enamel.
