Permanent Teeth
Permanent teeth, or adult teeth, are the second set of teeth that typically develop after a child loses all of their primary teeth. These teeth are meant to last a lifetime and are typically stronger and more durable than primary teeth. There are 32 permanent teeth in total, including 16 in the upper jaw and 16 in the lower jaw.

Milk Teeth
Milk teeth, also known as primary teeth or baby teeth, are the first set of teeth that develop in a child's mouth. These teeth typically begin to emerge in the first six months of life and are fully developed by the age of three. There are 20 primary teeth in total, including 10 in the upper jaw and 10 in the lower jaw.

Differences between Permanent Teeth and Milk Teeth
There are several key differences between permanent teeth and milk teeth, including:

- Permanent teeth are larger and stronger than milk teeth.
- Permanent teeth are meant to last a lifetime, whereas milk teeth are meant to fall out and be replaced by permanent teeth.
- Permanent teeth have longer roots than milk teeth, which makes them more stable and less likely to fall out.
- Permanent teeth have more complex shapes and are better suited for grinding and chewing food.

Why Milk Teeth are Important?
Milk teeth play an important role in a child's development. They help children to:

- Chew and digest food properly
- Speak clearly
- Maintain proper spacing for permanent teeth
- Develop good oral hygiene habits

It is important to take good care of milk teeth to ensure that they stay healthy until they are ready to fall out and be replaced by permanent teeth.
