  • because of the size of the jaw the crown is less;
  • the roots diverge, since they are the rudiments of the future teeth;
  • the enamel is significantly thinner, which makes the tooth more brittle;
  • pulp more;
  • root channels wide.

The roots of the incisors are fully formed by the age of two to four molars, and the canines only to five.

When a drop of milk teeth

To primary school age starts the process of replacement of milk teeth to permanent. So how does the expansion and growth of the jaw, between the teeth and cause cracks. This is a physiological process and necessary to the molars to give room as they are larger than milk. The bite changes from orthognathic in a straight line. Simultaneously with the appearance of space in milk teeth is the process of resorption of the roots, the circulation stops, the nerves die.

As soon as the milk teeth fall out, they replaced the cut permanent. Sometimes a baby tooth doesn’t want to give «familiar» place indigenous, in this case, you need to go to the doctor and remove it.
