Several factors can cause tooth decay. The main cause is a diet rich in sugars that help bacteria to eat away the enamel, although depending on the type of sugar, its incidence varies. Other causes include poor dental hygiene, the absence of fluoride in the water and own genetics, as proved that causes tooth decay in some children are especially sensitive to continue despite prophylactic correct habits.

While the bacteria S. mutans is primarily responsible for tooth decay, have found other factors that also show an unexpected correlation with this problem: complications during pregnancy or delivery, premature birth or cesarean delivery, maternal diabetes, kidney disease, Rh incompatibility, allergies, frequent gastroenteritis and chronic diarrhea. A diet high in salt and low in iron and pacifier use also seem to favor the development of caries.

Before the first tooth, about half of children aged 6 months and are infected with Streptococcus mutans. According to research, at 24 months of age 84% of children had developed a substantial colony. Factors associated with these cases were the intake of sweetened drinks at bedtime, taking too many sweet foods, snack between meals, sharing food with adults and a high presence of these bacteria in the mother. By contrast, the absence of bacteria was associated primarily with regular brushing of teeth.
