For many people, wisdom tooth removal feels like a universal milestone of young adulthood. Between the ages of 17 and 25, these third molars typically make their appearance—and often cause enough trouble to require extraction. But what if your wisdom teeth never come in? Is it possible to simply not have them at all?
What Are Wisdom Teeth?
Wisdom teeth, or third molars, are the last set of teeth to develop in the back of your mouth. Most people have up to four—one in each corner of the jaw. Historically, they served an important function for our ancestors, whose diets consisted of rougher, fibrous foods that required more chewing power.
However, as human diets and jaw structures evolved, these teeth became less necessary. Today, many people have smaller jaws that don’t have enough room for wisdom teeth to grow in properly, which can lead to impaction or misalignment.
Is It Possible to Be Born Without Wisdom Teeth?
Yes—some people never develop wisdom teeth at all! Studies suggest that about 5% to 37% of the population is missing at least one wisdom tooth, and some individuals are missing all four. This absence is known as hypodontia, and it’s largely determined by genetics.
Researchers believe that changes in the PAX9 and MSX1 genes play a role in whether or not someone develops third molars. If your parents or grandparents never had wisdom teeth, there’s a good chance you might not either.
Why Do Some People Still Have Wisdom Teeth?
Even though our jaws have gotten smaller over time, many people still develop wisdom teeth. Whether they erupt normally or become impacted depends on several factors, including jaw size, tooth angle, and spacing.
When there’s enough room, wisdom teeth can come in without causing any problems. However, if they’re trapped under the gumline or grow at an angle, they can lead to pain, swelling, infection, or crowding of nearby teeth. In these cases, removal is often recommended to protect your overall oral health.
How Do You Know If You Have Wisdom Teeth?
Even if you can’t see or feel them, your dentist can determine whether your wisdom teeth exist using dental X-rays. These images reveal whether your wisdom teeth are developing beneath the gums, have already erupted, or are missing entirely.
If your wisdom teeth are present but not causing any issues, your dentist may simply monitor their growth over time. But if they’re impacted or threatening nearby teeth, it’s better to plan a safe, proactive extraction.
What to Expect If You Need Wisdom Tooth Removal
Wisdom tooth extraction is a common procedure performed with the help of local anesthesia, sedation, or general anesthesia, depending on your comfort level and case complexity. After the extraction, mild swelling and soreness are normal for a few days, but recovery is typically smooth with proper care and rest.
Your dentist or oral surgeon will provide detailed aftercare instructions to ensure you heal quickly and comfortably.
The Bottom Line
Not everyone has wisdom teeth—and that’s perfectly normal. Whether you have all four, just a few, or none at all, your dentist can help monitor your oral health and ensure your smile stays healthy and pain-free.
