The baby teeth chart below shows when your child’s baby teeth (also called primary teeth or deciduous teeth) usually start appearing and falling out. Tooth eruption times vary from child to child.

As seen from the teething chart for babies, the first teeth begin to break through the gums at about six months of age. Usually, the first two teeth to erupt are the two bottom front teeth. Next, the top four front teeth emerge. After that, other teeth slowly begin to fill in, usually in pairs – one each side of the upper or lower jaw – until all 20 teeth (10 upper and ten lower jaw) have come in by the time the child is 2-3 years old. The complete set of primary teeth is in the mouth from the age of 2-3 years to 6-7 years.

Some facts about baby teeth development:

  • A general rule of thumb is that for every six months of life, approximately four teeth will erupt.
  • Girls usually precede boys in tooth eruptions.
  • Lower teeth, in most cases, erupt before the upper teeth.
  • Teeth in both jaws usually erupt in pairs – one on the right and one on the left.
  • Primary teeth are smaller in size and whiter in colour as compared to the permanent teeth that follow.
  • At 2 to 3 years of age, all the primary teeth of the child should have erupted. Shortly after four years of age, the facial and jaw bones of the child begin to grow and creates spaces between the primary teeth. This is an entirely natural growth process that provides the necessary space for the larger permanent teeth to emerge. Between the ages of 6 and 12, a mixture of both primary teeth and permanent teeth reside in the mouth.
