When do molar tooth germs form?

• A. When the jaw is fully lengthened
• B. At birth
• C. After eruption of deciduous teeth
• D. During late adolescence

Answer: (D)

Molar germs start forming later in development than the front teeth. The last molars, especially the third molars (wisdom teeth), have the latest initiation, often beginning their development during adolescence and then erupting in the late teens to early twenties. This timing explains why the correct choice points to late adolescence.

Jaw length changes aren’t what trigger tooth germ formation, and many molars begin their development well before birth or long before eruption of deciduous teeth. The fact that the last molars form late in childhood and into adolescence makes late adolescence the most accurate general timing for molar germ formation, particularly for the molars that erupt in the late teen years.
