Detailed explanation-1: -Deciduous teeth-also known as baby teeth, primary teeth, or milk teeth-are your first teeth. They start developing during the embryonic stage and start to erupt through the gums about 6 months after birth. All 20 of them are typically in by age 2½.
Detailed explanation-2: -The first teeth to erupt are the lower and upper central incisors, which erupt between the ages of 6 12 months. The next to erupt are the lateral incisors between 9-16 months, followed by the first molars from 13-19 months.
Detailed explanation-3: -Most babies will develop teeth between 6 and 12 months. Typically, the first teeth to come in are almost always the lower front teeth (the lower central incisors), and most children will usually have all of their baby teeth by age 3.
Detailed explanation-4: -Deciduous teeth, or primary teeth, are the first set of teeth that humans and other mammals develop. They are eventually replaced by permanent teeth, that begin to grow in throughout childhood.
