Babies are born without teeth. Baby teeth, also called as primary teeth usually start to appear when your child is 6 months old. By the time a child is 3 years old, most children will have a full set of 20 baby teeth in their mouth. However, this varies as each child is unique. Your child’s teeth may come in earlier or later.
Baby teeth can start to decay as soon as they come in as the enamel in baby teeth is thinner than in adult teeth. Sugar is present in almost everything a baby drinks like in breast milk, formula and 100% juices. Only water is sugar free. Acid from sugary drinks can stay on the teeth and can attack the teeth if it is on for 20 minutes or longer. When teeth are in contact with liquids that contain sugar then decay can start.
