Have you ever wondered why wisdom teeth exist? After all, they’re always late to grow, and often cause painful or damaging complications for the rest of your smile. So why have them at all? Believe it or not, they once served a very important purpose, even if it doesn’t seem that way now. If you’re curious, continue reading. You’ll explore why wisdom teeth exist and why dentists often recommend having them removed.
Why Does Anyone Have Wisdom Teeth?
Wisdom teeth are your third set of molars, typically erupting between ages 17 and 25. In terms of usefulness, they join a list of vestigial adaptations that our bodies keep around, like your appendix, tonsils, and tailbone.
Long ago, the early ancestors of mankind needed them to chew through tough foods like raw roots, nuts, and meat. These primitive people had larger jaws to accommodate these extra grinders, and having them meant that they could successfully get the nutrients they needed to survive.
Why Wisdom Teeth Aren’t Needed Today
Modern diets look very different from their ancient counterparts. When’s the last time you needed to eat the root of a tree or a slab of raw steak? Probably never. After all, thanks to cooking, softer foods, and utensils, you never have to struggle to eat.
Because of this, modern human jaws evolved to be smaller. Unfortunately, wisdom teeth never got the memo. That’s why many people don’t have enough space for them to grow properly.
Do Wisdom Teeth Always Need Removal?
Not always. Some people have enough space, and these teeth come in without causing problems. But for many, removal is the safest route to protect the rest of their smile. This is because instead of helping, they often cause:
- Impaction: Teeth trapped under the gums or jawbone.
- Crowding: Pushing other teeth out of alignment.
- Infection: Bacteria hiding in hard-to-clean spots.
- Pain: Pressure from improper eruption.
To get a clearer picture of your needs, your dentist will typically use X-rays or other digital scans to monitor whether your wisdom teeth are likely to cause trouble. If they’re impacted, causing pain, or crowding your other teeth, extraction is often recommended.
Wisdom teeth are fascinating reminders of the evolution of mankind. But while they once helped ancient man thrive, today they often create more problems than they solve. If yours start acting up, don’t wait for the pain to get worse. Reach out to your dentist to discuss whether extraction is the right path for you.
