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.
The onset of teething symptoms typically precedes the eruption of a tooth by several days. While a baby's first tooth can appear between 4 and 10 months of age, the first tooth usually erupts at approximately 6 months of age. Some dentists have noted a family pattern of early, average, or late teethers. A relatively rare condition, natal teeth, describes the presence of a tooth on the day of birth.
