Eruption of milk teeth
The eruption of the first milk tooth begins in the child’s mouth around the sixth month, and its eruption may be associated with some pain in the child. A total of twenty brown teeth, so that each jaw contains ten teeth, which are four incisors, two canines, and four premolars. The deciduous teeth are distinguished by the absence of a group of premolars, as it can be said that there are only permanent premolars, which will replace the deciduous molars. As for the permanent molars, they emerge behind the deciduous molars after space becomes available as a result of the maxillary growth in the sagittal direction. The first permanent tooth begins to erupt, which is the lower permanent first molar, at the age of six years. The family may not notice the eruption of this permanent tooth, especially since it may precede the start of deciduous tooth loss.
Eruption of permanent teeth
The first permanent tooth begins to erupt at the age of six, and all permanent teeth erupt until the age of twelve, except for the third molars (wisdom molars), which are delayed until the age of eighteen. It may never emerge for some, either due to a deficiency in the growth and movement of the tooth bud, or to its absence at all. An adult has 32 teeth, and each half of the jaw contains:
Two incisors – tuck and quadruple.
tusk.
Two laughs.
Three molars.
It is collected by the following verse:
Humans have quadruple incisors and canines on all four premolars
Two molars are twice as many as four molars, so know them, as knowledge is higher
