How many teeth do children have?
Children have 20 baby teeth, also called primary or milk teeth. They usually appear between about 6 months and 3 years of age.
The first teeth to appear are usually the bottom front incisors, at around 6 months old. By about age 3, most children have all 20 baby teeth: 8 incisors, 4 canines and 8 molars. Baby teeth have no premolars.
Baby teeth start to fall out at around age 6, as the permanent teeth growing beneath them push them out. Most children lose their last baby teeth by about age 12. The first permanent molars come in behind the baby teeth at around age 6 without replacing any of them.
Why baby teeth matter
Even though they fall out, baby teeth are important. They help children chew and speak clearly and hold space in the jaw for the adult teeth. Tooth decay in baby teeth can affect the permanent teeth, so dentists recommend brushing as soon as the first tooth appears.
Did You Know?
Babies are born with all 20 baby teeth already forming inside their jaws, hidden below the gums.
