Why do some people not have wisdom teeth?

11 Answers

Wisdom teeth usually develop between the age of 17 and 25 years. Some people have one,two,three or four while others have none at all. Lack of wisdom tooth might be as a result of dental abnormality. Also, you'll find that the tooth has grown but it lacks space to penetrate through other teeth but it's there only that it's not visible. For those that have visible wisdom teeth might have experienced some pain when they were growing because the force with which they penetrate between the teeth.

Final reason why some people lack wisdom teeth could be traced back to evolution. Wisdom teeth are classified as vestigial parts of the human body because we no longer use them like our ancestors who used to use them in eating raw food. Also, unlike our ancestors, the lower jaw is smaller to allow penetration of the wisdom teeth.

Not for everyone. That's a text book example. Nobody is the same. Look at coffee ☕for example. Ten people atleast half going to order it different. I'm sure some people get theirs earlier or later. Some may not.

The wisdom teeth grows lately and depends on your heredity so do not expect the growth of wisdom teeth on everybody. Wisdom teeth may shown up on some people.

They are present but still haven’t erupted yet. Wisdom teeth may never erupt if they are impacted (not enough space for them to grow) and may remain dormant in the jaw bone for many years. The lack of wisdom teeth is related to genes.

Not everyone has the same thing. That's like saying why doesn't everyone like hot pink? It's different for different people. Comes at different ages. I had surgery for mine.

In my view, if they do not have wisdom teeth, then we can consider it congenital. It happens when a person grows older without them. It can also be explained as idiopathic.

The gene that causes a lack of wisdom teeth, is estimated that anywhere from 5 to 37 percent of people are missing one to four wisdom teeth. The other factors that might influence the lack of wisdom teeth include environment, diet, and chewing function. Sometimes, impacted or stuck in the gums and as result, they don't fully emerge.

This is likely because of genetic variation. Wisdom teeth are the third molars that usually appear in the late teens or early twenties. Some people may not develop wisdom teeth due to a lack of space in their mouth or due to their genetic makeup. Additionally, wisdom teeth may not form properly, or they may be impacted, meaning they are unable to erupt through the gums.

The cause of not having wisdom teeth is different for each person. Some people may have wisdom teeth because they are born with a perfect tooth, while others may have wisdom teeth because their families were able to keep some of their teeth. There is no specific answer, as the cause of not having wisdom teeth may vary depending on the individual's family and lifestyle.

The reason is unknown, but lack of these teeth could involve genetics. So if one of your parents doesn't have wisdom teeth, you may not have them either. Other factors that might influence the lack of wisdom teeth include environment, diet, and chewing function.

Evolutionary adaptations caused some humans to have smaller jaws, leaving no room for wisdom teeth. Modern diet may also play a role.

Many people do not have wisdom teeth because of evolution. This might sound funny or even unreal but this is real - just like some people that are not born with appendix. The wisdom teeth should come in  a total of 4 teeth on each person, however some people only develop 1, 2 or even none. Others (like myself) have all of them. There is also a possibility that you have them but they never come out, which means they stay inside of your gums forever. These teeth can cause lots of pain and can destroy the job done by braces, that is why it is always a very good idea to have them surgically removed by a professional dentist, that way you do not have the risk of having your smile ruined.
