How many deciduous teeth should be replaced?

Everyone must have experienced tooth replacement. Some people may not feel anything when their baby teeth fall out, and they will find that they are gone when they wake up the next day. However, some friends have to have their teeth extracted every time they change, and they have to go to the hospital. This is everyone's nightmare when they were young. So, do you really understand the tooth replacement we are familiar with? How many teeth should we change in our lifetime, and what is the difference between baby teeth and adult teeth?

Humans are geminidentates and have two sets of teeth in their lifetime, namely deciduous teeth and permanent teeth. Humans should have 20 deciduous teeth, including 8 deciduous incisors, 4 deciduous canines, and 8 deciduous molars. They usually erupt between 6 months and 2.5 years after birth. The tooth replacement period is between 6 and 12 years old. The deciduous teeth gradually fall out naturally, and the permanent teeth erupt (including six-year molars). By the time the second molars grow out, there are 28 teeth in the mouth, including 8 incisors, 4 canines, 8 bicuspids, and 8 molars.

Most people's third permanent molars (i.e. wisdom teeth) erupt between the ages of 18 and 25. Due to human evolution, the third permanent molars tend to degenerate, and some people have one or two fewer third permanent teeth (i.e. wisdom teeth) or even no third permanent teeth (i.e. wisdom teeth) at all. So adults generally have 28 to 32 teeth.

What should you pay attention to when caring for your baby teeth?

1. Keep the mouth clean: Although children do not need to brush their teeth during childhood, it is best to let them drink some boiled water after each meal and before going to bed to clean the remaining food in the mouth and protect the deciduous teeth.

2. Ensure adequate nutrition: Add complementary foods to children in a timely manner and ensure adequate nutrition to ensure the normal structure and shape of their teeth and improve their resistance to dental diseases.

3. Proper tooth exercise: Babies who are teething should often be given harder foods, such as biscuits, toast slices, apple slices, carrot slices, etc., to exercise the chewing muscles and promote the development of teeth and jaws.

If you are an expectant mother, then this information is very important to you. There are many things that expectant mothers need to know in advance after the baby is born to avoid being caught off guard. If you are already a mother, it is not too late to know now. Help your child correct wrong habits in time and pay attention to the movement of your child's teeth changing. If the teeth do not fall out for a long time, go to the hospital for medical treatment in time, just in case.
