Why a One-Year-Old Child Has Only Grown Two Teeth: Causes and Recommendations

Question

A one-year-old child has only grown two teeth, and the parents are concerned. They hope to understand the possible causes and professional advice.

Answer

The timing of tooth eruption in children varies from person to person. If parents have been supplementing calcium for their child, a late eruption of teeth may not be due to calcium deficiency. A slower rate of tooth eruption may be related to genetic factors, and gender differences can also affect the timing of tooth eruption; usually, girls’ teeth erupt earlier. If the child is premature, their overall development may be slower, which can affect the rate of tooth eruption. Additionally, abnormal pituitary hormone secretion or incomplete ectodermal development may also lead to a slow rate of tooth eruption. It is recommended that parents bring their child to the hospital for a detailed examination to determine the specific cause.
