Why do people grow wisdom teeth? Is long wisdom tooth good or bad?

in life, many people will grow teeth when they reach adulthood, which is often called "wisdom teeth". But long wisdom tooth is not a happy thing, but it will bring a lot of troubles to your life. Why do adults grow wisdom teeth?

1. The so-called wisdom teeth are the third molars that grow one tooth at the bottom of the alveolar bone. And this tooth will grow out after adulthood, so it is regarded as a symbol of wisdom, so it is called "wisdom tooth".

2. Why grow wisdom teeth? This is because a person's jaw is almost the same as that of an adult when he is in adolescence, but some people's jaws are not very big, so there is not enough space for wisdom teeth to grow out, and the growth of wisdom teeth is limited, so they can only develop in other directions. Either it grows in part, or it's all buried in the jaw. Because the space for growth is limited, wisdom teeth can only grow towards the adjacent teeth, thus creating an angle with the third molar, and will squeeze the third molar.

3. As for when to grow wisdom teeth, there is no exact time. Some people grow before they are 20 years old, while some people may not grow until they are 40 or 50 years old, and some people will not grow in their life. This is normal. However, wisdom teeth will not grow completely. Some people will only grow one, some will be two, and some will only grow half.
