Question

This is the first child in the family. The mother wants to know when she should expect her son to start getting his permanent teeth. Which of the following is MOST often the first permanent tooth to erupt into the mouth?

1) Incisor
2) Canine
3) Premolar
4) Molar

Answer 1

The first permanent tooth to typically erupt in a child's mouth is the molar, specifically the first molar, which appears between the ages of 6 and 7.

Step-by-step explanation:

The first permanent tooth to erupt in a child's mouth is most often a molar. Specifically, the first permanent molars, also known as the 6-year molars, typically emerge behind the last baby teeth without replacing any deciduous teeth. They usually appear between the ages of 6 and 7. Incisors are generally the first deciduous teeth to fall out and are replaced by permanent incisors. However, they are not the first permanent teeth to erupt. The sequence of tooth emergence can vary in individuals, but the first molars are most commonly the first to make an appearance in the permanent dentition.

Answer 2

The first permanent tooth to erupt is typically a molar, known as the six-year molar, usually appearing between the ages of six and seven.

Step-by-step explanation:

The first permanent tooth to erupt after the deciduous (baby) teeth begin to fall out is usually a molar. Specifically, these are often the six-year molars, or first permanent molars, which do not replace any deciduous teeth but come in behind the last baby teeth. This commonly occurs between the ages of six and seven. Permanent molars are important for establishing the back of the dental arch and are crucial for proper chewing and grinding of food. Parents can generally expect to see these first molars appear once their child begins to lose their baby teeth.
