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.
By around age 12, your child should have all of his permanent teeth. Expect your child's baby teeth to start to fall out in early elementary school, around age 6. Baby teeth usually fall out in the same order they came in. The two bottom front teeth tend to go first, followed by the two top front teeth.
