What is the Difference Between Deciduous and Permanent Teeth?

The main differences between deciduous (primary) and permanent (adult) teeth are in their composition, structure, number, and susceptibility to erosion. Here are the key differences:

1. Composition: Deciduous teeth have thinner enamel than permanent teeth, making them appear whiter and more susceptible to tooth decay.
2. Structure: Deciduous teeth are smaller and have a different root structure than permanent teeth. Their roots are thinner and shorter than those of permanent teeth.
3. Number: There are 20 deciduous teeth, while there are 28-32 permanent teeth, including eight premolars and third molars (wisdom teeth).
4. Susceptibility to Erosion: Deciduous teeth are more susceptible to erosion due to their thinner and more porous enamel layer.

Deciduous teeth, also known as baby teeth or milk teeth, act as placeholders for permanent adult teeth and play an important role in helping a child learn to eat and speak. They start to erupt when a child is around 6 months old and are gradually replaced by permanent teeth from the age of 6. Good oral care is essential for both deciduous and permanent teeth to ensure their longevity and overall dental health.

Comparative Table: Deciduous vs Permanent Teeth

The main difference between deciduous and permanent teeth is that deciduous teeth are temporary and develop at birth, while permanent teeth develop at the age of 5-6 years and remain throughout life. Here is a table summarizing the differences between deciduous and permanent teeth:

Deciduous teeth are also known as primary or baby teeth, and they are eventually replaced by permanent teeth through a process called exfoliation.
