Is 32 teeth normal?

Generally speaking, the number of teeth in our mouth is fixed. Generally speaking, the number is between 28 and 32, but few people have 32 teeth. So, is 32 teeth normal? In fact, this is also a normal phenomenon. This is mainly because all four wisdom teeth have grown out, so the number of teeth has increased. However, for some wisdom teeth, they need to be removed because they affect oral health.

Wisdom tooth refers to the third molar on the innermost alveolar bone in the human mouth, which is exactly the eighth tooth counting from the central incisor. Because it erupts very late, generally between the ages of 16 and 25, when a person's physical and psychological development are close to maturity, it symbolizes the "arrival of wisdom" and is therefore commonly called "wisdom tooth." There are great differences between individuals in the growth of wisdom teeth. Normally, there should be four teeth that are symmetrical in the upper and lower left and right directions. Some people have less than four or even none, and very few people have more than four. The age difference of eruption is also very large. For some people, it erupts before the age of 20, some people erupt at the age of 40 or 50, or never erupt in their lifetime. This is all normal.

Modern medicine generally believes that wisdom teeth are remnants of human evolution. Since wisdom teeth grow at the end of the alveolar bone, the alveolar bone of modern humans has degenerated to varying degrees in length, width, and strength due to increasingly refined eating habits, resulting in it being unable to provide sufficient space for the eruption of wisdom teeth. As a result, wisdom teeth often erupt ectopically or are impacted due to lack of space. In addition, the degeneration of the wisdom teeth themselves can also lead to insufficient number of erupted teeth and asymmetric eruption. These eruption abnormalities, coupled with the difficulty in cleaning and prevention, usually manifest clinically as pericoronitis of wisdom teeth, caries of wisdom teeth or adjacent teeth, periodontitis, pulpitis and other diseases, causing severe pain. Therefore, it is recommended to preventively extract abnormal or asymmetrically erupted wisdom teeth as early as possible.

What kind of wisdom teeth are worth keeping?

1. The position is relatively correct and is expected to erupt normally.

2. There is no history of inflammation or pain in the soft tissue around the wisdom teeth, and there is no caries in the wisdom teeth.

3. Wisdom teeth that are opposite to the teeth.

Wisdom teeth, like the appendix, are the remains of human evolution. The appendix is ​​an organ used by humans in primitive times to digest crude fiber, such as foods like tree roots, while wisdom teeth are teeth used to chew crude fiber foods such as tree roots and bark to help the human digestive system. With the progress of human beings, food has become more and more refined, and humans have gradually degenerated the things they no longer need. The size of the lower jaw has become smaller, and there is almost no space for wisdom teeth to grow on the jawbone, and the upper jaw no longer has opposing teeth.
