As our bodies mature, various changes occur. Among these changes, dental development is a vital aspect that individuals should pay attention to. Understanding which molars undergo change is crucial for maintaining good oral health. In this blog post, we aim to decode the dental development process by addressing some commonly asked questions regarding molars and their transformation.

What are molars?

Molars are the flat teeth located at the back of your mouth. They are responsible for grinding and chewing food before it passes through the digestive system. Typically, adults have a total of twelve molars: four on each side of the upper and lower jaw.

  • First Molars: The first molars, also known as the six-year molars, usually appear around the age of six. They replace the primary molars and are permanent teeth.
  • Second Molars: The second molars, commonly referred to as the twelve-year molars, appear around the age of twelve. These molars are also permanent teeth.
  • Third Molars (Wisdom Teeth): Wisdom teeth, or the third molars, typically emerge between the ages of seventeen and twenty-five. However, they may not develop in everyone. In some cases, wisdom teeth may cause complications and require extraction.

Which molars undergo change?

The molars that undergo change during dental development are the primary molars, which are eventually replaced by the first and second permanent molars. The third molars (wisdom teeth) can also undergo changes, but these changes are not as significant.

What changes occur in primary molars?

Primary molars, also known as baby molars, begin to erupt around the age of six months and continue their development until a child is six years old. During this period, they serve as placeholders for the permanent molars.

As the permanent molars develop, they push against the roots of the primary molars. This pressure causes the roots of the primary molars to resorb, essentially dissolving them. As a result, the primary molars loosen and eventually fall out, making way for the permanent molars.

How do first and second permanent molars change?

Once the primary molars have fallen out, they are replaced by the first and second permanent molars.

The first permanent molars (six-year molars) appear at the back of the mouth, behind the primary molars, without replacing any teeth. They erupt at around six years of age and are essential for maintaining proper spacing in the mouth.

The second permanent molars (twelve-year molars) come in behind the first molars and replace the primary molars. These molars usually erupt around the age of twelve. They complete the set of twelve molars in adult dentition.

Understanding the dental development process and the molars’ changes is crucial for maintaining optimal oral health. By knowing which molars undergo change, you can better care for your teeth, identify possible issues, and seek appropriate dental treatment when necessary. Remember to consult with your dentist regularly to ensure your molars and overall oral health are in excellent condition.
