What type of teeth are absent in case of a baby?

In many species, milk teeth erupt soon after birth; in a few, they erupt and are replaced by adult teeth in utero; and in some, they appear to be absent altogether. The milk teeth consist of incisors, canines, and premolars; molars come in later as part of the adult dentition and are not replaced.

Do 2 year olds have all their teeth?

Why does my 2 year old not have teeth?

Genetics: Delayed tooth eruption may just run in the family. If the child’s parent had teeth that erupted late, there’s a chance the child’s teeth will erupt late, too. Genetic conditions such as Down syndrome, amelogenesis imperfecta, and regional odontodysplasia can also delay tooth eruption.

• canines (beside the front molars)
• second molars.

Why some babies get teeth late?

Babies who were born premature or had a low birth weight can get their teeth late and may also have enamel defects. Some genetic conditions, such as amelogenesis imperfecta and regional odontodysplasia, can cause teeth to erupt late and be poorly formed.

How many teeth should a two year old have?

The typical two year old will have 12-16 teeth. However, not everyone is textbook. As a pediatric dentist, I have had a few patients with only 8 teeth by age 24 months. There are few kids that have all 20 by age 2, but that makes it easier to get cavities because you have to care for the baby teeth earlier. Remember, not everyone is average.

What is it called when you don’t have any baby teeth?
