Tooth Eruption
The bottom front tooth, called central incisor, is normally the first tooth that erupts around 6-8 months of age.
At around 2-1/2 to 3 years old, your child may have all 20 baby teeth.
Between the ages of 5-7, the first permanent teeth will begin to erupt. Most children complete the 28 permanent teeth around 11-13 years old.
