Tooth growth has actually occurred since I was still in the womb. However, the first tooth will emerge from the gums when the baby is around 6-12 months old.

The first teeth to appear in children are known as baby teeth. At least, your child will have 20 baby teeth by the age of three that grow gradually, 10 each in the upper and lower jaws. Furthermore, entering the age of 12-14 years, the majority of children already have permanent teeth called adult teeth.

How Many Teeth Are Adults?

Of course, the number of teeth in adults is not the same as the teeth in children. The normal number of teeth for adults is 32 teeth, including the back molars or wisdom teeth. The following is the division of adult teeth by type:

1. incisors

4. Molars

Molars can be called the teeth that are most often used. This type of tooth is also referred to as the strongest tooth with the function of crushing and chewing food.

Causes of the Number of Adults’ Teeth More or Less than Normal

As it turns out, the number of teeth in an adult can be more or less than normal, in this case 32. If the number is more than normal, this condition is referred to as hyperdontia. Meanwhile, the number of teeth in adults is less than normal is called hypodontia.

  • Unable to chew food well.
  • Feel sick and uncomfortable.
  • It is difficult to clean the teeth which can lead to other medical conditions.

Meanwhile, hypodontia occur due to congenital abnormalities or defects. Usually, the number of teeth that do not grow or is missing is less than 6. In addition, there is also a condition called oligodontia. This disorder occurs when 6 or more teeth cannot grow because they fail to develop.

Although this condition is common, treatment is still needed to close or repair the gaps that form between the teeth. Because, if treatment is not carried out, a number of other conditions are prone to occur, including:

  • Decreased self-confidence.
