The phenomenon of a baby developing the four lower teeth first may stem from various factors, including genetic and physiological developmental differences, as well as the impact of nutrition and health status.
Genetic factors are an important reason that cannot be ignored. If several family members have had early tooth eruption, the baby may be influenced by genetics and also develop the first set of teeth in the lower jaw early.
Additionally, the growth rate of babies varies; some children start to develop teeth around six months old, and the order of tooth eruption often follows from the bottom up or from the front to the back. These individual differences may lead to the lower teeth emerging first.
On the other hand, pathological factors should also be considered. A lack of vitamin D and calcium can interfere with calcium absorption, affecting the process of tooth calcification and altering the normal growth order of teeth, which may lead to the lower teeth developing first. Insufficient maternal nutrition during pregnancy, excessive medication, or local stimulation caused by a baby’s exposure to hard foods may all affect the timing and order of tooth eruption, resulting in the phenomenon of lower teeth emerging first.
In light of this, parents need not worry excessively. As the child grows, most children will gradually have all their primary teeth within one to two years. During this period, parents should pay attention to their child’s oral hygiene and safety to prevent injuries to the new teeth. If there are any concerns, it is advisable to consult a pediatric dentist for targeted guidance and assistance.
