How many teeth does a person have, and how many teeth does a normal person have

How many teeth does a person have?

Baby teeth: Children before the age of 6 will have 20 baby teeth, 10 on the top and 10 on the bottom. Among them, there are 8 deciduous incisors, 4 deciduous canines and 8 deciduous molars, which generally erupt between 6 months and 2 and a half years of age.

Permanent teeth: are the second set of human teeth, with a total of 32 teeth. From the age of 6, the baby teeth begin to fall out gradually, and the permanent teeth begin to erupt, replacing the baby teeth, except for the third molar, the remaining 28 generally erupt at about the age of 12.

Molars (wisdom teeth).

The germination time is late, at the age of 18-30 years, and some do not germinate or partially germinate for life (all 4 in total). Theoretically, an adult should have 32 teeth, but the number of teeth that really function is 28, and generally 28 and 32 are normal.

Some people will ask: Do wisdom teeth count as teeth? Of course, some people's wisdom teeth may not grow for life. Wisdom teeth generally grow at an age of 18-30 years old, and if you don't have wisdom teeth before the age of 30, they will basically not grow.

A normal adult has about 28 to 32 teeth. After puberty, the number of teeth in the human body can reach 28, which is a normal physiological phenomenon, but some patients will have wisdom teeth at this age, which may grow 1 4 or up to 32.

Patients should strengthen the protection of teeth in daily life, and can try to avoid the occurrence of caries, gingivitis and other diseases.

A normal person's teeth will have 28-32 teeth.

There are two sets of teeth in a person's life, the first set of teeth is classified as deciduous dentition, which begins to erupt from about 6 months of birth, and completes the eruption of deciduous teeth around the age of 2. There are 5 each on the upper, lower, left and right sides, including deciduous central incisors, deciduous lateral incisors, deciduous canines, first deciduous molars, and second deciduous molars, a total of 20. From the age of 6-7 to 12-13 years, baby teeth gradually fall out and are replaced by permanent teeth, which are the second set of dentition after the loss of baby teeth.

Precautions for protecting your teeth.

Chewing exercise: So masticatory exercise is the full movement of the masticatory muscles. We need to eat harder and rougher often, and it is best to choose high-fiber foods, so that we can effectively exercise the masticatory muscles, and also allow the tissues around the teeth to be fully protected.

Gum massage: It can promote blood circulation in the periodontal tissues, promote the metabolism of the supporting tissues of the teeth, and correspondingly improve the disease resistance of the teeth. Gum massage can be performed in or out of the mouth, so in the process of protecting the teeth, you should also brush your teeth frequently, and every corner must be carefully brushed when brushing, so as to bring better results.
