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.
Children start to lose teeth anywhere between five to seven years of age, but some kids can begin losing teeth as early as age four. Kids usually lose their teeth in the order they first appeared. The top and bottom front teeth, called central incisors, are usually the first to come in and the first to fall out.
