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.
Kids usually lose their first tooth by the age of 6 or 7, and they lose the last tooth, which is the second molar, by the age of 12 or 13. A tooth can sometimes take a few days or even a few months to fall out once you or your child notices that it's loose.
