How many teeth does a normal person have? How many teeth does an adult have?

Teeth are a very important organ in the human body. They play many roles in the human body, such as assisting pronunciation, chewing food, protecting the oral cavity, maintaining facial shape, etc. People usually start to grow teeth at the age of 1 to 2 years old, and after a period of tooth replacement, their teeth are basically complete. Wisdom teeth are a special case and are not included. So how many teeth do adults have? Let’s take a closer look.

A normal adult has 28-32 teeth. The first 20 teeth, No. 1-5, are replaced by deciduous teeth, and No. 6-8 are permanent teeth that erupt on their own. Usually, No. 8 is the wisdom tooth. The number of wisdom teeth each person has varies. Some people have wisdom teeth, while others do not. When wisdom teeth become skewed or ectopically erupted, they need to be removed. Generally speaking, adults need to perform pit and fissure sealing when tooth No. 6 erupts, and they need to perform sealing again when tooth No. 7 appears to prevent tooth decay. Teeth 28-32 of adults are no longer replaced, so they must be well protected. At the same time, the periodontal tissues must be protected. If there is tartar around the gums, it is recommended to remove it in time and perform teeth cleaning regularly, about once every six months to a year. If caries or food impaction occurs, you should go to the dental department for treatment in time. If a tooth is cracked, it is recommended to extract it immediately. If the wisdom tooth is not in the opposite jaw, extraction is recommended to prevent biting of the cheek mucosa or the gums of the opposite jaw. Long-term stimulation may cause ulcers or tumors.

Functions of Teeth

Teeth not only help chew food and pronounce, but also have a great impact on the beauty of the face. Due to the support of teeth and alveolar bones, normal dental arch shape and occlusion, a person's face and lips and cheeks appear plump. When people talk and smile, neat and white teeth can better show their health and beauty. On the contrary, if the dental arch develops abnormally and the teeth are arranged disorderly and unevenly, the face will appear uncoordinated. If too many teeth are missing, the lips and cheeks will lose support and become sunken, making the face look old and thin. Therefore, people often regard teeth as one of the important indicators of bodybuilding.

Dental Care:

1. Make sure you brush your teeth effectively every time you brush your teeth!

Implement the "three-three system": brush your teeth three times a day, each time for three minutes or more. At the same time, it should be noted that when brushing your teeth, the bristles should be at a 45-degree angle to the tooth surface, and the brush head should be rotated to ensure that every tooth is brushed. The toothbrush should be moved back and forth on the upper and lower tooth surfaces to ensure thorough cleaning. Remember not to brush your teeth sideways or too hard.

2. Choose a toothbrush and toothpaste that suits you.

Toothbrush: Only by choosing a health toothbrush that meets the requirements of oral hygiene can you achieve the effect of cleaning teeth without damaging the teeth and periodontal tissues. The characteristics of a health toothbrush are: a small brush head that rotates flexibly in the mouth; the bristles are arranged reasonably to facilitate cleaning teeth, and the toothbrush itself is easy to clean after brushing; the bristles are thin and elastic; the top of the bristles is round, which is not easy to damage teeth and gums. In addition, an electric toothbrush is also a good choice. The slight vibration generated by its high-speed rotation can not only promote blood circulation in the oral cavity, but also has a massage effect on the gum tissue.

Toothpaste: In order to prevent tooth decay, you can choose an anti-caries toothpaste with a repair function. The formula contains free fluoride ingredients that can directly act on the surface of the teeth. Cracked areas of the teeth are particularly susceptible to absorbing free fluoride. Therefore, free fluoride can play a directional repair role and effectively repair damaged enamel, thereby preventing bacterial invasion.
