What are The Key Differences Of Temporary Versus Permanent Teeth

difference between deciduous and Permanent Teeth

Teeth are an important part of the body that starts developing right in the embryonic stage. Apart from helping us in chewing, teeth also help in speech and facial aesthetics.

We have two sets of teeth in a lifetime: one is temporary, called deciduous teeth, and the other is permanent, called adult teeth.

This blog particularly intends to highlight the morphological the difference between deciduous and permanent teeth, also educating you on how to care for them.


Temporary Teeth

The temporary teeth are the first teeth set that start emerging after 6-8 months of a baby’s birth. Temporary teeth are also called deciduous teeth because they fall after six years, and a new set of teeth replace them. The temporary teeth develop in the fetal stages, but it spurts on the gumline after six months of birth.

Temporary Vs. Permanent teeth


Permanent Teeth

As the name suggests, permanent teeth stay permanently with us until they fall off their own or are uprooted intentionally. They are also called adult teeth, and there are 32 permanent teeth. The number of permanent teeth is more as compared to the temporary teeth, and as the jawline expands while growing, these extra teeth expand and cover the full stretch of the jawline.

A lot of morphological (developmental) changes happen when a child grows. The jaws become hard and  robust. To adapt to the physiological change, the teeth sets replace. The permanent teeth are stronger, darker in color, and have bulbous roots.

The key difference between difference between deciduous and permanent teeth can be studied as:

Other names

Temporary teeth are also known as milk teeth, deciduous teeth, or primary teeth.

Permanent teeth are also called adult teeth or secondary teeth.

Number Of Teeth

There are 20 temporary teeth.

There are 32 permanent teeth.

Morphological  Difference 

10 teeth in the upper jaw and 10 in the lower jaw.

  • 4 incisors
  • 2 canines
  • 4 molars

      (in one jaw)

The permanent teeth have

  • 8 incisors
  • 4 canines, or cuspids.
  • 8 premolars, or bicuspids.
  • 12 molars, including 4 wisdom teeth.

Developmental differences

The crown appears brighter and wider, whereas the roots are larger and slender in dimensions.

The number of crowns increases and appears packed.

 The teeth structure becomes robust and darker than temporary teeth, and the roots become shorter and bulbous.

The temporary teeth eruption paves the way to the proper eruption of permanent teeth. The temporary teeth roots are elongated to grapple gums strongly, and by the time permanent teeth appear, the gums have already become hard. Therefore structurally,  second sets are also tough sets of teeth with more rounded and intact teeth in their sockets.

There are many differences between deciduous and permanent teeth, but there are many similarities. The similarities are:

  • Both teeth sets have incisors, canines, and molars.
  • The teeth structure comprises  enamel, dentine, crown, root, and pulp.
  • They both function for the same, i.e., chewing and speech.


Pro Tips To Care “Milk Teeth”

The milk teeth are harder, shiny, and more prone to cavities. Therefore parents must teach their tots to brush twice every day. They must provide them with a good brush and fluoride toothpaste that helps to ward off cavities.

Most importantly, parents must consult a pediatric dentist for their child before the very first year ends so that the pediatrician can glimpse into the child’s teeth development and highlight an issue that exists.

Pro Tips To Care “Adult Teeth”

Adult teeth are already developed, strong, and hard, and they are supposed to last for a lifetime. Still,  some dental issues such as cavities, gum issues, or improper teeth development can bother you and call for action. Therefore, it is essential to care for your dental hygiene and visit the dentist bi-annually or once every six months so that they may assess your mouth and indicate necessary care or remedial solutions.
