Primary teeth development
As of 6 months of age, teeth and molars start to develop. The following overview shows exactly when teeth and molars erupt.
- deciduous incisor, erupts between 6 and 9 months.
- deciduous incisor, erupts at 12 months.
- deciduous canine, erupts at 20 months.
- deciduous molar, erupts at 16 months.
- deciduous molar, erupts between 12 and 30 months.
Replacement of deciduous teeth
At the age of 5 or 6, milk teeth are replaced by permanent teeth. This process usually starts with the replacement of the front teeth. After a few years, all deciduous teeth will be replaced. The replacement process will take up to six years. The roots will dissolve, the teeth will fall out and the permanent teeth and molars will erupt.
The first permanent molar usually erupts at the age of 6. This molar will erupt behind the deciduous teeth. At the age of 12 to 14, the process is completed, except for one kind of molar. The last molars, which sometimes do not erupt at all, erupt at the age 18 to 21 and are called wisdom teeth. The normal adult mouth will contain 32 teeth and molars, 16 in the top jaw and 16 in the bottom jaw.
