How many teeth does a normal person have

Children usually grow deciduous teeth about 6 months after birth. When the deciduous teeth fall off, permanent teeth begin to grow. The permanent teeth will be stronger and sharper. However, most people have 28 permanent teeth when they just grow permanent teeth. Four wisdom teeth will come out after adulthood, so normal people usually have 32 teeth. However, many people choose to remove wisdom teeth. So how many teeth do normal people have?

Each person has 32 permanent teeth, of which 28 are functional teeth.

Generally, 28 to 32 teeth are normal, of which 28 are symmetrical above and below, including 2 central incisors, 2 lateral incisors, 2 first premolars, 2 second premolars, 2 first molars, and 2 second molars, totaling 28 teeth in total. There are also 4 wisdom teeth. Some people have them while some don’t. It is normal to have any number of them.

When one or two teeth fall out, it will not affect the health of the whole body. However, when the teeth gradually fall out and there are less than 20 teeth left, it will begin to affect the functions of multiple systems of the body. At this time, if the fallen teeth are repaired in time and more than 20 functional teeth are kept in the mouth, the aging rate of the human body will slow down, which is beneficial to prolonging human life. This is because when a person has less than 20 teeth, food cannot be fully chewed, which affects the digestive function; the pronunciation of speech will be adversely affected, the appearance will appear old, and it will have a negative impact on the person's psychology. In addition, teeth are important organs of balance in the body. Many physical activities and concentrated mental work require the cooperation of teeth occlusion. When a person has less than 20 teeth, his or her balance function is affected, making him or her prone to making mistakes in activities and falling.

Under normal circumstances (if there is no missing teeth or supernumerary teeth), adults have 28 to 32 teeth, including 32 teeth if they have four wisdom teeth. Children begin to grow deciduous teeth about six or seven months after birth, and have all 20 deciduous teeth by the age of two and a half. It is not until around the age of six that the child starts to change his teeth and the first molars, commonly known as sixth-year molars, grow out. Around the age of fourteen, all the teeth are replaced, with a total of 28 teeth (generally). Wisdom teeth begin to grow between the ages of 18 and 25 (it varies from person to person, and some people's wisdom teeth do not erupt at all). There are 14-16 teeth in the upper jaw and 14-16 teeth in the lower jaw. The number of teeth you have is determined by your DNA, which means it's something you're born with. Sometimes wisdom teeth erupt, or the elderly's gums absorb too much, and the supernumerary teeth that were originally buried inside are exposed, and it feels like a new tooth has grown.

Wisdom teeth are the four third molars on the innermost part of the alveolar bone, one on the upper, lower, left and right sides. There are great individual differences in the growth of wisdom teeth. Some people grow them before the age of 20, some at the age of 40 or 50, and some never grow them in their entire lives. This is all normal.
