Age Six to Seven. Between the ages of six and seven, your child may lose his first tooth. The lower central incisors are usually the first teeth that are lost, followed by the upper central incisors. At this point, eating is slightly affected, although your child may prefer to do most of his chewing on the back teeth.
However, because the small roots should dissolve first, loose teeth should not be yanked out abruptly. Otherwise, it is possible for the remaining root to break and become infected. What to Expect explains that baby teeth typically start falling out when a child is 6 years old. The Parents website states that baby teeth can fall out as early as 4 years old or as late as 8 years old. Teeth emerge and drop out following the same pattern.
