Wisdom tooth removal has become somewhat of a rite of passage – puffy-cheeked post-extraction photos, a diet of Jell-O and mashed potatoes. But not everyone gets their wisdom teeth taken out. In fact, not everyone has wisdom teeth at all! Have you ever wondered why some people have four wisdom teeth while others have fewer or even none? We’ve got the facts behind how many wisdom teeth people have and why!
Why do we have wisdom teeth?
Third molars, or wisdom teeth, were once very useful to our ancestors. Because prehistoric man’s diet of hard-to-chew plants and uncooked meat required powerful chewing muscles, our ancestors’ jaws were large enough to fit 32 teeth, not just 28. Now that humans have evolved a better means of chewing and digesting our food, we no longer have large jaws, so we simply have no need or no room for wisdom teeth. Many scientists believe humans are currently evolving third molar hypodontia, or the lack of wisdom teeth, due to their inability to develop in the first place.
How many people have wisdom teeth?
About 20-25% of the human population is born with 1 to 3 wisdom teeth, and 35% is born without any wisdom teeth at all.
Why do some people have wisdom teeth and some don’t?
There are a few reasons why scientists believe that not everyone develops wisdom teeth:
- Genetics: Some evidence suggests that a genetic mutation occurred hundreds of thousands of years ago, causing some people to be born without wisdom teeth.
- Environment: Percentages of people who develop wisdom teeth varies from culture to culture. Certain ethnic groups are known for low percentages of wisdom teeth development, while others are known for high percentages. Environmental factors during dental development are also a possible explanation.
Will wisdom teeth become obsolete?
With the number of people lacking wisdom teeth steadily growing, it’s possible that we could someday completely evolve to not develop wisdom teeth at all. Scientists have experimented with chemically preventing the development of wisdom teeth. Researchers have found that children ages 2-6 that are given local anesthesia for dental work have a higher chance of not developing wisdom teeth later on. Maybe in the future, simple injections at a young age will keep all of us from having to go through wisdom tooth extraction!

Are missing teeth causing you difficulty, discomfort or embarrassment? Don’t worry – we have all the facts about tooth replacement treatments and the effectiveness of dental implants as a long-term solution for missing teeth.
What are dental implants?
Dental implants are replacement teeth made of titanium. They are composed of an artificial crown attached to a screw that is surgically implanted into the jaw for stability. Implants are an effective treatment for missing teeth because they maintain the strength of the jaw.
There are a few alternative treatment options, some more lasting than others:
Flippers are temporary, removable plastic teeth. They are attached to a retainer for easy removal. Flippers are one of the most cost efficient tooth replacement methods; however, they are the least durable alternatives to dental implants and are considered short-term solutions until a more lasting treatment can be performed.
Fixed bridges literally “bridge” gaps caused by one or more missing teeth. A dental bridge consists of a false tooth, called a pontic, and two abutment teeth, which are crowns that anchor the bridge to the teeth on either side of the gap. Abutment teeth can be secured to both natural teeth and dental implants; however, anchoring them to natural teeth can cause damage.
Dentures are a common treatment for individuals missing all their teeth in one or both of their jaws. They are made of a removable frame that holds an entire set of teeth.
Removable partial dentures are removable frames that hold a partial set of teeth rather than a full set of teeth. This option is often considered for individuals who are missing some but not all of their teeth in one or both jaws.
Why choose dental implants?
Implants are the longest lasting treatment for missing teeth. With proper care, dental implants can last up to ten years or longer. Because they are surgically anchored into the jawbone, they function like natural teeth.
