Dentition Troubles

 The teeth which are erupted in infancy are known as the milk teeth. These teeth are 20 in number and are gradually replaced by permanent teeth which number 32.

     The eruption of the teeth begins at about the sixth month although some children begin dentition later. It is usually finished by the second year. Any condition which interferes with unutrition or any constitutional disease which disturbs calcium metabolism result in delayed dentition and eruptions of imperfectly developed perishable teeth.

     The usual order of eruption is as follows : At six to eight months, the two lower central incisors followed one month later by the upper central incisors ; next the upper lateral incisors and at the end of one year anterior molars ; at 14 months the lower lateral incisors come through the gums and then the lower anterior molars. Between 16 and 18 months the canine teeth eruptions and the end of two years the posterior molars appear. Ordinarily at the end of one year there are six teeth ; at 18 months there are 12 teeth ; at two years 16 teeth ; and at two and one-half years, the 20 milk teeth should all have erupted.

     The eruption of the permanent teeth begins about the sixth year, the six years molars being the first to appear. At seven to eight years the incisors erupt ; at nine to ten years the bicuspids ; at 12 years the canines ; between the twelfth and fifteenth year the second molars ; and between the seventeenth and twenty-first year the third molars or wisdom teeth.

     Dentition is a purely physiological process and should run a normal, uneventful course. Unfortunately, this is not always the case, and there is no doubt that many infants are unnaturally peevish and uncomfortable and have derangements of digestion when they are teething.

     Proper care of the teeth is a hygienic essential as carious teeth are a serious menace to health. The milk teeth should be preserved as long as possible for premature loss interferes with the growth and development of the jaw.
