Why do wisdom teeth grow?

Core Tip: Why Wisdom Teeth grow? People have two sets of teeth in their lifetime.
A pair of deciduous teeth begins to grow around 6 months after birth and begins to fall out at the age of 6. After the deciduous teeth fall out, a pair of permanent teeth gradually grows for life. From 6 to 12 years old is the exchange period of deciduous and permanent teeth…
There are 20 deciduous teeth in total, 10 in each of the upper and lower jaws, and 32 permanent teeth in total, 16 in each of the upper and lower jaws. With the growth and development of the human body, the jawbone also widens and lengthens accordingly. In addition to the 20 permanent teeth that grow on the original 20 deciduous teeth, the two ends of the upper and lower jaws are arranged in order from front to back. Three pairs of large molars grow: the first pair grows around 6 years old, the second pair grows around 12 years old, and the third pair usually grows around 18 to 25 years old, but There are no. The third pair of large molars appear when young people are around 20 years old and are in the period of growing their bodies and knowledge, so people call the third pair of large molars that grow during this period as wisdom teeth. Why do I feel pain when wisdom teeth appear? Because the wisdom teeth are the last to grow, the distance between the distal end of the mandible and the second pair of molars is very small, and the position of the wisdom teeth is not enough, and the crown can only grow in part. If the alveolar bone is very hard, the wisdom teeth will grow in the direction of alveolar osteoporosis. As a result, the wisdom teeth will grow horizontally or grow obliquely in the mesial direction. At this time, there will be a feeling of distending pain. If the surface of the tooth crown is covered by a part of the gums, a pocket is formed between the tooth surface and the gums, and food residues are easy to collect in the pocket. When brushing and rinsing, the food residues are not easy to wash out, which creates favorable conditions for the growth and reproduction of bacteria. When the body’s resistance is low, the gums of wisdom teeth often become inflamed. Normal wisdom teeth are good for chewing, but if they are not positioned correctly, they are not easy to correct, and often induce gingivitis. It is better to remove them as soon as possible, which is more beneficial to health.
