These are called the primary teeth, baby teeth, or milk teeth and there are 20 in all. When a child gets to age 5 or 6, these teeth start falling out, one by one.
Teething: 4 to 7 Months. Teething usually starts during these months. The two front teeth (central incisors), either upper or lower, usually appear first, followed by the opposite front teeth. The first molars come in next, followed by the canines or eyeteeth. There is great variability in the timing of teething.
