Why do some people not have wisdom teeth

There are three main reasons why wisdom teeth may be lacking inside the mouth: 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 related to genes.

Why do some people have missing wisdom teeth?

These teeth were named for the time at which they make their appearance at the very back of the mouth, which is usually between the ages of 17 and 25, when a young person might be pursuing wisdom with higher education. A study shows that up to 35% of people have missing wisdom teeth. Why do some people lack wisdom teeth?

Why don’t my parents have wisdom teeth?

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.

Are there people born without wisdom teeth?

People born without wisdom teeth. As we said, up to 35% of people are born without wisdom teeth. The study we referred to earlier concluded that the absence of wisdom teeth is a result of evolution. As the human brain has expanded over hundreds of thousands of years and continues to do so, it is taking up increasing space in the skull.

Why do wisdom teeth erupt?

Because human jaws have become smaller throughout evolutionary history, when wisdom teeth form they often become impacted, or blocked, by the other teeth around them. Also, if the tooth partially erupts, food can get trapped in the gum tissue surrounding it, which can lead to bacteria growth and, possibly, a serious infection.

Why is my wisdom tooth not getting infected?

The reason is that wisdom teeth sometimes do not emerge normally and become trapped or impacted within the jaw. A passageway develops when your wisdom tooth emerges partially, and this can cause problems mainly because the area is hard to clean and is more likely to become infected.

Are your wisdom teeth impacted?

But a third, more likely possibility is that your wisdom teeth are impacted. In other words, your jaw doesn’t have enough room for them to erupt, so the teeth become trapped below the gumline. The American Association of Oral and Maxillofacial Surgeons says that nine out of 10 people have at least one impacted wisdom tooth.

What happens if your wisdom teeth dont erupt?

Wisdom teeth that do not erupt but remain tucked away can also lead to oral problems, such as crowding or displacement of permanent teeth. On very rare occasions, a cyst (fluid filled sac) can form in the soft tissue surrounding the impacted wisdom tooth. These cysts can lead to bone destruction, jaw expansion, or damage to the surrounding teeth.
