Tooth decay caused by?
The cause of tooth decay is due to bacteria available in the mouth, mainly Streptococcus Mutans, when food is stuck on the surface of the teeth, especially sugar and starch, the bacteria will decompose food to create acid that corrode tooth enamel. forming a deep hole

.
Bacteria, acids, food humus on the tooth surface will form a sticky film called dental plaque, this film is very sticky and is present in all tooth surfaces, especially molars, dental plaque not only causes decay teeth but also cause gingivitis and inflammation around the teeth.
The plaque is gradually mineralized by the minerals in saliva and food that form tartar.
After the enamel is eroded into a hole, the more bacteria and food are able to attach, the more acid is created, the harder the organization (enamel and dentin) will be, the deeper the hole will expand and toward the pulp
People with gums and tooth root loss, the dental plaque will stick up and start the process of decomposing food to create acid on the surface of the tooth neck and root, the hard tissue of the tooth is eroded to form a deep hole.
