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.
Babies may begin teething as early as 3 months old, or well after their first birthday, but 6 months of age is a fairly common time for teething to begin. Your child's behavior may clue you in to when it's almost time for a tooth to emerge, or erupt, through the gums. Babies are often fussy for up to five days or so before a tooth breaks through. Their gums become tender, sore and swollen.
