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.
Primary teeth become loose and fall out because the secondary teeth, also known as permanent teeth, begin to emerge and need room to grow. At the age of 12 or 13, most kids have lost all of their baby teeth and will have a full set of permanent teeth. A pediatric dentist will assist you in the care of your teeth from when you are a baby until you are a teenager.
