The main thing in this period is to help the child as easy as possible to experience unpleasant symptoms.

The timing of eruption

If, as it follows from the standard terms, the child has not yet started the process of eruption, do not panic. Dentists say that a deviation of up to 6 months, and in any direction is not considered pathology. The average age for the appearance of the first teeth in 6-8 months, but it has to happen otherwise there really is cause for concern. Factors influencing this may include the following:

  • Hypothyroidism. With an insufficient amount of hormones produced by the thyroid gland, the body is slower;

Children’s dental formula

The dental formula of milk teeth is necessary for a quick calculation of their numbers by this age. Parents can check to be sure normal development of their child. Permanent and milk teeth differ in many respects — size, color enamel, inner structure, the degree of mineralization of the enamel, and therefore the formula of the child is not the same that that of an adult.

Clinical formula

Scheme for milk teeth is written in Roman numerals and are as follows:



Names of milk teeth is the same for upper and lower row, here I and II are the incisors, III — fangs, IV and V large indigenous, while indigenous yet. On this basis, can be calculated according to the formula the number of molars — each number is represented by the number of teeth:

2 0 1 2 2 1 0 2

2 0 1 2 2 1 0 2

It’s only 10 molars on the upper gum and the same on the bottom, just to 4 years the child should receive 20 teeth.

For the calculation of permanent molars to the above formula is added two pairs of premolars. That is, each of the jaw arcs will be for 16 units, in the amount of 32 teeth — the norm for an adult.

How is the teething
