There are many factors that influence the formation of cavities in baby teeth. However, the main, and most common cause of most cavities in children, is a lack of oral hygiene.
Not brushing your teeth and gums after every meal, or doing so incorrectly, provides an ideal avenue for bacteria in your mouth to develop and form bacterial plaque. Leftovers from food and drink serve as food for their growth.
Baby teeth have less protection than adult teeth, as the pulpal cavities (where the nerve resides) are wider, so they are more at risk of being severely exposed.
In addition, consumption of foods high in sugar is another critical factor in cavities in babies. Simple sugars are consumed by bacteria, favoring the release of acids that damage enamel.
