Baby's First Teeth: Facts Parents Should Know

What Are Deciduous Teeth?

First teeth start to erupt from 6-10 months after birth. There are typically 20 deciduous teeth — 10 upper and 10 lower. They are start to grow from the middle to both sides.

The names of the five teeth are:

  • Central incisor
  • Lateral incisor
  • Canine
  • First molar
  • Second molar.

How The Deciduous Teeth Growing?

Generally the lower teeth are earlier than the corresponding upper teeth, and the girl’s teeth are earlier than the boy’s.

Typically, baby's first teeth will start growing in when baby are about 6 months old.

  • The first tooth to grow is usually the central incisor at middle of lower.
  • The second central incisor to grow is right next to the first.
  • The next two teeth to grow are usually the two upper central incisors. After these two upper central incisors have grown out, two upper lateral incisors will grow next to the upper central incisors. They usually start erupting about two months after the same tooth on the lower grow. Then the next two lower lateral incisors will grow.
  • After all the incisors have grown out, two lower canines and two upper canines will grow. But they do not next to the incisors. 
  • The next four to grow between the incisors and the canines are the first molars, two upper and two lower. 
  • The second molars are usually the last of the 20 deciduous teeth.

Every baby is different, so the time and sequence of eruption of baby's first teeth are also different. Early teething does not mean good growth, and late teething does not mean delayed growth.

For example, the eruption time of the baby's first tooth varies from 6 to 10 months, so there is no need to worry too much during this time period.

The medical definition of delayed teething is that the first deciduous tooth has not grown after 13 months. There are many reasons for delayed tooth eruption, which may be idiopathic, or it may be related to heredity, disease and food shape. If the baby is diagnosed with delayed teething, it is best to seek medical attention in time to find out the cause.
