The original oath was written in Ionic Greek, in the late Fifth Century BCE. It is usually included in the Hippocratic Corpus. Scholars widely believe that Hippocrates or one of his students wrote the oath between the 5th and 3rd century BC.
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 average child gets his first baby tooth at age six months and then gets three to four new teeth every three to four months. This continues until the second molars erupt at about age two to two and a half years, at which time your child should have all twenty baby teeth. If your child got his first tooth early or finished getting all of his baby teeth early, then he might start losing his baby teeth early too. On the other hand, if he didn't get his first tooth until age twelve or fifteen months, then he might be a little later than average in shedding or losing his first tooth.
