Wisdom teeth are annoying?

Koreans call wisdom teeth “love teeth” because they grow in their late teens and early teens. Many people think that excess teeth should be removed.

The first wisdom tooth recorded 15,000 years ago grows underground under the gums of a European woman. Researcher Alan Mann, of Princeton University, says wisdom teeth are a “scar of human evolution”. History of human evolution, the brain grows very fast, tripling the original size causing the skull size to change, the jaw structure shrinks, there is no room for wisdom teeth to grow. But because the genes that determine the structure of teeth evolve separately from the genes that control brain development, people are having problems with their wisdom teeth.

The number of wisdom teeth that grows in a person’s life may be one, two, three, or four, and some may not. There are also people who grow more than four wisdom teeth, called supernumerary teeth. According to Dr. William McCormick, associate clinical professor at West Virginia University of Dental Sciences, genetic factors such as the size of the jaw bone can determine a person’s number of wisdom teeth.

World medical documents have recorded many cases of abnormal time of wisdom teeth. The ancient philosopher Aristotle wrote in his book The History of Animals: “There was an old lady in her 80’s – the last stage of her life – but her wisdom teeth were beginning to erupt, causing a lot of pain. happened to the old men. “

In 2017, the Guinness Book of World Records recognized Mr. Robert W. Gray (USA) as the oldest person to have wisdom teeth near the age of 95. He discovered that a new wisdom tooth grows while brushing in the morning. According to Dr. William, most cases of wisdom teeth in the age of 17-25, but “still can not predict when teeth erupt”. The doctor who treated a 65-year-old patient had to have dentures fitted but the wisdom teeth were still inserted.

Wisdom teeth are the source of stem cells. According to William Giannobile, editor of Dental Research, Japanese scientists have been studying the success of creating stem cells from living cells of wisdom teeth, which have amazing regenerative potential. Research on mice by scientists at Pittsburgh Medical University shows that stem cells taken from teeth can be used to treat corneal damage caused by infection or trauma. “There have been studies using stem cells from wisdom teeth to treat neurological disorders and eye diseases,” Dr. Pamela Robey, National Institute of Dental and Skull Research, told CNN.

Wisdom teeth are called by many different names. In Japanese, wisdom teeth are called “oyashirazu” (parents’ unknown teeth), because most people grow when a person is an adult and no longer lives with their parents.

In the US, wisdom tooth prophylaxis is quite common. Many people have wisdom teeth extracted without pain or problems arising from this tooth. Whether or not wisdom tooth extraction should be controversial.

There is a view that most people will have problems with wisdom teeth in the future. “It is difficult to give an exact figure, but at least 75-80% of oral cases are not qualified to maintain the wisdom tooth until the end of life,” said Dr. Louis K. Rafetto. He said that in the United States, an average of 3.5 million wisdom tooth surgeries are performed every year, equivalent to 10 million wisdom teeth removed.

For some people, wisdom teeth are “slow explosive bombs”, affecting the bite, chewing food, causing tooth erosion, tooth decay, can seriously lead to cysts, nerve damage … However, dentist Jay Friedman says only about 12% of wisdom teeth cause pain. He compared this low rate with 7-14% of appendicitis cases, emphasizing that the appendix was only removed when the patient had pain. Dr. William has similar thoughts, saying that only wisdom teeth should be extracted when infected, an abscess appears.

“Think about the risks that can occur with wisdom tooth extraction, although serious complications such as jaw fractures and death are extremely rare,” he said.
