Just from the childhood days only, we follow some of the basic oral hygiene habits. Brushing, rinsing, and few other habits are some of the basic oral hygiene habits that most of us follow.


However, some of us might have wondered about How many teeth do we have in a lifetime? Well, the answer will be bifurcated in two categories as per the total teeth with only adult teeth and the other with milk teeth. When a person develops adult teeth, they become permanent for life.


There are 32 permanent teeth in total. Before understanding the total number of teeth, it is important to know the difference between temporary and permanent teeth. All these teeth have to be maintained in a proper way.

What is the difference between temporary and permanent teeth?

1. Permanent teeth are hard and temporary teeth are soft

As the milk teeth are soft they are easily prone to food that destroys the teeth like juice, soda, and other flavored waters. The soft enamel of the teeth breaks down quickly and develops the cavities easily.


It further causes the grinding of the primary teeth that further might break the teeth. The permanent teeth have strong enamel and are sturdier comparatively which makes it difficult to destroy easily.


2. Baby teeth are whiter than the permanent teeth

The color of the permanent is yellowish than the baby teeth that can be easily noticeable. It is easily noticed particularly when the permanent teeth erupt next to the baby teeth


3. Baby teeth have large pulp chambers than permanent teeth

When compared to the size of the tooth, the size of the pulp chambers is more in the case of the permanent teeth. It causes the infection or inflammation to affect the teeth.


4. Shape of the teeth

The shape of the baby teeth is much like a cubical form. So the point of contact between the two teeth is large. In the case of adult teeth, they are more rounded which makes a smaller point of contact.


As there are some of the basic differences between these two sets of teeth, it can be easy to determine the type of teeth. As we have understood the difference between both, it will now be easier to know the total teeth in humans.
