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.

Erupting permanent teeth cause the roots of baby teeth to be reabsorbed so that by the time they are loose there is little holding them in place besides a small amount of tissue. Most children lose their baby teeth in this order: 1  Baby teeth ordinarily are shed first at about age 6 when the incisors, the middle teeth in front, become loose. 2  Molars, in the back, are usually shed between ages 10 and 12, and are replaced with permanent teeth by about age 13.
