The lower front teeth are often the first teeth that appear in an infant at the age of six months, and they are also known as the central incisors.
After 4 to 8 weeks, the four front upper teeth, called the central and lateral incisors, begin to emerge.
After about a month, the lower lateral incisors appear, which surround the lower front teeth.
Finally, the molars that help grind food appear, all of which are called deciduous teeth.
