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.
Most kids have their first loose tooth at age 5 or 6, but it can happen when they're as young as 4 or as old as 8. (Children whose baby teeth erupted early usually lose them before late teethers do.) It generally takes a few months from the time a tooth becomes loose until it falls out.
