In the human mouth, the number of teeth varies from 28 to 32. This subtle difference actually stems from what we call four "hermits" - wisdom teeth. They grow quietly after the age of 16, and more than half of people between the ages of 16 and 20 will encounter them.
But why do doctors always exhort us to remove these four "hermits"? Their harm is actually much deeper than we think. First, they can subtly affect the surrounding teeth, causing other teeth to begin to loosen or even die.
Secondly, the appearance of wisdom teeth can induce inflammation, making us feel severe pain when chewing, swelling, and even affect our diet. Furthermore, over time, the presence of wisdom teeth can cause us to gradually lose our bite function, eventually causing us to be unable to chew food normally.
Of course, there are some lucky people who have wisdom teeth that do not affect the bite and do not cause inflammation and tooth decay. But such lucky ones are only a few after all, and they are like pearls hidden in the crowd, difficult to find. For most people, their wisdom teeth will bring a lot of trouble to their lives.
