Spot Text: Does every person have wisdom teeth is a common question in dental care. Wisdom teeth, or third molars, typically emerge between the ages of 17 and 25. However, not everyone develops them, as evolutionary changes and modern diets have led to a reduction in their necessity. For those who do, these molars can contribute to dental health challenges, such as crowding and misalignment, often leading to removal. Understanding their potential functions and the reasons behind extraction can help individuals navigate their oral health effectively, ensuring optimal care and prevention strategies.
Wisdom teeth, medically referred to as third molars, are the last set of teeth to emerge, typically during late adolescence or early adulthood. These teeth are located at the very back of the mouth, with two on the upper jaw and two on the lower jaw. The term "wisdom teeth" arises from the age at which they appear—when an individual is presumed to have gained some wisdom.
Their primary function in ancient human diets was to help grind and chew coarse, raw foods such as roots, leaves, and meat. As these teeth develop, they usually follow the natural sequence of molar eruption. However, in modern individuals, this process has become increasingly inconsistent due to a variety of factors.

The role of wisdom teeth has evolved over time. Anthropological studies suggest that our ancestors had larger jaws, allowing ample space for all 32 teeth, including wisdom teeth. These extra molars were necessary due to the wear and tear from consuming rough diets that lacked modern food processing and preparation techniques.
However, as human diets became softer and easier to chew—especially with the introduction of cooking and modern food tools—our jaws began to evolve into a smaller size, making the development of third molars less consistent. This evolution explains why some people never develop wisdom teeth at all, and why others may experience complications like impaction.
In fact, studies show that up to 35% of people are born without at least one wisdom tooth, a phenomenon known as agenesis of third molars. This number continues to grow, indicating that wisdom teeth may become completely obsolete in future generations.

Not everyone develops wisdom teeth—a phenomenon that surprises many patients. In fact, the absence of third molars is more common than previously thought. The presence or absence of wisdom teeth is not a random occurrence but a complex interplay of evolutionary, genetic, and environmental factors.
Scientific studies suggest that agenesis, or the failure of a tooth to develop, is especially frequent in the case of wisdom teeth. While the average adult has four third molars, many individuals may have only two, one, or none at all. This variability often depends on ancestral lineage and genetic inheritance. For instance, people of East Asian descent are statistically more likely to be missing one or more third molars compared to those of European descent.
In some cases, wisdom teeth development may initiate but never complete, meaning that the teeth are present but remain embedded within the jawbone. These "invisible" molars can only be detected through dental X-rays.

One of the most significant factors affecting the development of wisdom teeth is genetics. Studies from the National Institute of Dental and Craniofacial Research show that certain genes, such as PAX9 and MSX1, are linked to third molar formation. If these genes are inactive or absent, the molars may never form. This is especially interesting in modern populations, as the number of individuals born without wisdom teeth continues to rise—potentially marking an evolutionary shift.
Environmental factors also play a crucial role. Dietary habits, particularly in childhood, can influence jaw size and shape. A softer modern diet, rich in processed foods, requires less chewing, which can contribute to smaller jaw development. As a result, even if the genetic blueprint for third molars exists, the available space in the jaw may not accommodate them, leading to impaction or failure to erupt.
Furthermore, the early loss of baby teeth or orthodontic interventions during adolescence can change the alignment of the jaw and affect how or whether wisdom teeth emerge at all.

Long before modern dental care and processed foods became the norm, wisdom teeth served a crucial purpose in our ancestors’ lives. Often referred to as third molars, these teeth were essential for chewing coarse, fibrous diets consisting of roots, nuts, raw meat, and tough vegetation. Their emergence typically marked the transition into adulthood—both biologically and functionally.
In early human evolution, tooth loss due to wear or decay was common. Having extra molars meant increased efficiency in grinding food and a backup system when front molars deteriorated. According to anthropological studies published in The Journal of Human Evolution, the role of wisdom teeth was adaptive—they compensated for tooth loss and maximized food breakdown, aiding digestion.
From an anatomical perspective, our ancestors had broader jaws to accommodate all 32 teeth comfortably. There was no concept of impaction or dental crowding because the jawbone structure matched the dietary demand.
Fast-forward to today, and you’ll see that our dietary evolution has dramatically altered the way our jaws develop. With the rise of soft, cooked, and processed foods, there is significantly less stress placed on the jaw during chewing. This change begins in childhood, meaning the jaw doesn’t grow as wide or robust as it did for our ancestors.
As a result, although third molars development is still genetically encoded, the modern jaw often lacks space for these teeth to emerge without causing problems. This is why impaction, misalignment, and crowding are now so commonly associated with wisdom teeth.
Moreover, because our oral hygiene has improved and food is easier to chew and digest, the functional necessity of wisdom teeth has diminished significantly. Dentists now view these molars as vestigial—similar to the appendix in the digestive system—serving little to no purpose in many individuals.

One of the most common removal reasons for wisdom teeth is impaction. This occurs when the tooth doesn't have enough room to erupt fully or grows in at an incorrect angle. Impacted third molars may remain trapped within the gums or partially emerge, leading to pain, swelling, and potential infection.
Impacted wisdom teeth can cause significant dental health impacts, including cysts, damage to adjacent teeth, and gum disease. According to the American Association of Oral and Maxillofacial Surgeons, 9 out of 10 people experience at least one impacted wisdom tooth in their lifetime. These complications often necessitate prompt intervention through surgical extraction procedures.
Infections associated with impaction can spread quickly. Bacteria can accumulate in the soft tissue around partially erupted molars, causing pericoronitis—a painful condition that may require antibiotics or emergency extraction.
Even if your wisdom teeth are not impacted, they may still pose a risk to the alignment of your existing teeth. Wisdom teeth presence in a crowded jaw can exert pressure on neighboring teeth, leading to shifting or overlapping—especially noticeable after orthodontic treatments like braces.
This movement can undo years of alignment correction and result in bite problems or jaw discomfort. Orthodontists frequently recommend removing wisdom teeth as a preventive measure, even if they aren’t currently causing discomfort, to preserve long-term dental symmetry.
Moreover, crowding caused by third molars may increase the risk of cavities and gum inflammation, especially in hard-to-reach back molars. This reinforces why early assessment and removal is often part of comprehensive dental care plans.

The extraction procedure for wisdom teeth can vary based on the tooth’s position and condition. For fully erupted teeth, a simple extraction might suffice. However, impacted third molars—which remain beneath the gum line—typically require a surgical approach.
Before the procedure, your dental surgeon will conduct a thorough evaluation using digital X-rays to determine the tooth’s location and proximity to nerves and sinuses. You’ll receive local anesthesia, sedation, or general anesthesia depending on the complexity of the procedure and your comfort level.
During the extraction, a small incision is made in the gum to access the tooth. Bone tissue may be removed, and the tooth might be divided into sections for easier removal. The procedure typically lasts between 20 to 60 minutes per tooth.
Patients often worry about pain during extraction. With today’s techniques and sedation options, discomfort is minimal. According to the Mayo Clinic, most extractions are completed without significant complications, provided they are done by experienced professionals.

Recovery from wisdom teeth extraction procedures generally takes 7–10 days, depending on how impacted the tooth was. Immediate post-op care is crucial to prevent infections or complications such as dry socket—a painful condition where the blood clot dislodges prematurely.
Recommended aftercare strategies include:
Pain management typically involves over-the-counter medications or prescribed analgesics. Some mild bleeding or discomfort is normal, but if severe symptoms persist, you should consult your oral surgeon immediately.
Maintaining dental health during recovery is essential. Proper hygiene, rest, and nutrition help accelerate healing and minimize dental health impacts.

The presence of wisdom teeth requires consistent dental monitoring—even if they’re not causing immediate discomfort. Routine check-ups, including panoramic X-rays, allow dentists to assess third molars’ development, alignment, and potential risks.
Preventative care is essential, as impacted or partially erupted wisdom teeth can create hidden pockets for bacteria, increasing the risk of infections, cysts, or even gum disease. Moreover, modern dietary influences and softer food textures mean our jaws are smaller, making crowding more likely when third molars begin to erupt.
Dentists often recommend proactive removal even when symptoms aren’t present. This is especially true in young adults between 17–25 years old, when the roots are not fully formed, making extraction easier and recovery faster.

Wisdom teeth, also known as third molars, generally begin to develop in the late teenage years. For most people, these teeth start to erupt between the ages of 17 and 25. However, this can vary based on individual genetic and environmental factors. Some may notice signs earlier, while others might not develop these molars at all—a result of ongoing evolutionary dental changes and modern dietary influences.
It’s important to schedule a dental check-up during this period. Early imaging such as panoramic X-rays allows your dentist to assess the wisdom teeth presence, their position, and any potential alignment problems before they become symptomatic.
