Question

A 10-month-old baby has only grown two teeth. Is this normal?

Answer

Generally, babies will have four to six teeth by the time they are ten months old, but everyone grows at a different pace. The timing and order of tooth eruption can vary greatly from person to person, and normally, the growth of primary teeth does not affect the arrangement of permanent teeth. Here is a guide to the timing and order of primary tooth eruption:

  1. Central incisors: Lower jaw around 6 months, upper jaw around 7.5 months
  2. Lateral incisors: Lower jaw around 7 months, upper jaw around 9 months
  3. Second primary molar: Lower jaw around 12 months, upper jaw around 14 months
  4. Canines: Lower jaw around 16 months, upper jaw around 18 months
  5. Third primary molar: Lower jaw around 20 months, upper jaw around 2 years Some children may have individual differences in the order of tooth eruption, but this usually does not affect the alignment of the teeth. Typically, babies with good nutrition and higher height and weight will have their teeth erupt earlier than those with poor nutrition. It is recommended to supplement calcium for the baby.
