Have you ever wondered why you have not a single teething? That is, why do not we stay with the first teeth, called "baby teeth", but falling just giving way to new ones? Or why not three changes have teeth? The latter could be very useful to us in times when we have problems with parts of the second does not it?

 

Parts of the tooth

Teeth In dentistry , we understand that the teeth are structures formed by the crown and root. The crown is the visible portion in the mouth and is made available by the enamel (the outer layer), dentin and pulp, commonly called nerve. The root is inserted in the bone of the jaw and, unlike the crown, comprises cement, instead of enamel, dentin and pulp.

 

 

Why we change your teeth?

All parts of our body are developed to a greater or lesser extent during the growth period, in which genetic factors fundamentally influence. In the case of teeth, although we think otherwise, once they formed not grow. Its size is genetically constituted. Note that when the first tooth or teeth poke into the mouth enlarge, only the root develops until it is perfectly adjusted and simultaneously teeth are "accommodating" in the arcade.

As time passes, the teeth are distributed in the available space along the jaws, which do increase its size until the patient completes its growth. In the case of children, their jaws at first are small and have little space to accommodate the teeth, which is why they come out so slowly. When the appearance of the teeth is completed, they amount to twenty and are smaller than those of the second dentition, which become more than 32.

As the jaws and the rest of the body continue to grow, the teeth would be a bit ridiculous in a maxillary already developed. It is for this reason that the progressive change of teeth for the final starts.

 

How many teeth do we have?

How is it that the teeth are twenty and thirty-two final? The twelve new teeth that appear are placed in the arcades, behind the last tooth of milk and are the wheel of six years, twelve years and the trial. This is performed on each side of both jaws, which constitutes a total of twelve. The first definitive tooth comes out is that of six years and is so called because at that age usually it erupts. Indeed, as the former it is also the most affected by decay.
