Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The first permanent tooth usually erupts at age ____
A
6 months
B
6 years
C
12 years
D
21 years
Explanation: 

Detailed explanation-1: -The first permanent teeth that emerge in the oral cavity are the maxillary and mandibular first molars at around six years of age (six-year molars). They erupt distally to the deciduous second molars.

Detailed explanation-2: -What Are Six-Year Molars? The six-year molars are permanent, adult teeth that begin to erupt just behind a child’s second or second-year molars at around age six. Since these teeth are new growth, they will not fall out and be replaced by new teeth like your child’s baby teeth.

Detailed explanation-3: -When Do Children Start Getting Permanent Teeth? The baby teeth begin to fall out, and the first permanent teeth customarily appear around 6 or 7 years old. The teeth are called the ‘six year molars’ and emerge in the back of the jaw, making it easy to mistake them for primary teeth.

Detailed explanation-4: -Genetics play a large role in determining when your child’s baby teeth fall out and their adult teeth come in. Typically, kids lose their top 4 teeth and bottom 4 teeth between ages 6 and 8. The remaining 12 teeth, which are canines and molars, are lost between ages 10 and 12.
