Introduction
The dentition is the entirety of the teeth of the upper and lower jaw (maxilla and mandible). The development of the teeth begins in the dental arch before birth. At the age of 6 months the first teeth appear in the oral cavity (cavum oris), which is the beginning of the digestive tract.
Usually they are the central incisors of the lower jaw. Gradually, the remaining teeth of the upper and lower jaw also break through the gums, and at the age of 2 years, the tooth breakthrough is complete. However, there are also harmless deviations in the breakthrough times.
So the appearance of the teeth can occur sooner or later. The painfulness of the eruption is also very different in children. These teeth form the 1st dentition and are called milk teeth. The milk teeth (decidual dentition) comprise 20 teeth, the small molars (premolars) are missing. The permanent or permanent dentition of the 2nd dentition comprises 32 teeth.
Milk teeth
The eruption of the milk teeth usually starts with the 2 central incisors (Incisivi) of the lower jaw, followed by the 4 upper incisors, the 2 lateral lower incisors, the first molars, the canines and finally the second molars. The milk teeth are smaller than the permanent teeth and have a thinner enamel layer. This makes them more sensitive to acid attacks.
Therefore, a dental check of the milk teeth is absolutely necessary to detect and repair damages in time. An early loss of milk teeth leads to difficulties in breaking through the permanent teeth. If it is still necessary to remove milk teeth, the insertion of a space maintainer is recommended.
Before the permanent teeth appear, the milk teeth move apart due to the growth of the jawbone to make room for the permanent teeth. At the same time the roots of the milk teeth are resorbed, they loosen and fall out. In some cases a milk tooth remains, which must be removed, otherwise the breakthrough of the permanent tooth is disturbed.
