Why are there two sets of teeth?

Until now, you must have understood the basic difference between milk teeth and permanent teeth. Here, we will look at it in more detail.

Here are some of the detailed difference between milk teeth and permanent teeth:

1. Number of teeth

This is one of the basic differences between both, where there are 20 milk teeth and 32 permanent teeth in a person. In the case of milk teeth, each jaw has canine pairs, two lower and upper pairs of incisors, one first molar pair, and one-second molar pair.

2. Size of teeth

The size is the most easily observable difference between the milk teeth and permanent teeth. Milk teeth are smaller in size when compared to permanent teeth. So, this is the reason that they erupt first during the childhood days. Later, there is an eruption of the permanent teeth when a person turns to an adult.

3. Composition in teeth

The layer of the enamel on the milk teeth is very thin in comparison to the permanent teeth. This is the reason for the cavity getting easily developed in the children due to the thin layer on milk teeth. It also has a lesser surface bond cavity due to decay or crack in the teeth. The permanent teeth are stronger in comparison to the milk teeth.

4. Color appearance

The milk teeth are whiter in color when compared to the permanent teeth. The differences between these teeth are clearly visible when the permanent teeth start erupting neighboring to the milk teeth. It makes many of the parents worry as the yellowish layer is visible clearly among their children. It is important to preserve the permanent teeth from getting stained as they will accompany for a prolonged period.

5. Pulp chambers

The pulp chambers of the milk teeth are larger when compared to the permanent teeth. This part contains blood vessels and nerves which is very essential to hold the teeth in a stronger position. Thinner enamel along with the large pulp can cause cavities with some infection to the teeth. Pulp chambers usually get infected during adulthood when the tooth catches cavities. The pulp area needs to be cleaned to get the proper treatment with respect to it.

So, these are some of the differences between milk teeth and permanent teeth. It is very necessary to know the difference between them, as they both have different ways of caring. Every set is prone to different types of dental issues that can be easily analyzed.
