Chances are you know someone who needed a wisdom tooth extraction. If not, maybe you are that someone! This is one of the most common dental treatments in the US, and yet, the origin and purpose of wisdom teeth are largely mysterious.
Fortunately for curious types everywhere, you wouldn’t be the first to wonder why humans still develop third molars if they usually have to be pulled. Keep reading for some illuminating answers!
Who Usually Gets Wisdom Teeth?
Wisdom teeth are most common in younger individuals aged 17 – 21. There are cases of them developing in patients a little earlier or a little later in life, though, and roughly 50% of the population won’t develop any! Interestingly, men seem to be more likely to have them than women.
While it’s still fair to say most adults will have to contend with at least one wisdom tooth, it’s not necessarily a bad sign if you never see sight of them!
Why Do Wisdom Teeth Emerge So Late?
That’s a really good question, especially considering when first and second molars develop. Molars (the flat teeth that sit towards the back of your mouth) emerge in sets of four. So the first four molars start to show around age 6, while the second set emerges close to age 12. There’s a pretty sizable gap between second molars and wisdom teeth!
Some scientists suspect that third molars functioned as back-up teeth. Before modern dental advancements, tooth loss was far more common – theoretically, wisdom teeth could replace missing pearly whites.
What’s the Purpose of Third Molars?
Besides the back-up theory, there’s also speculation that third molars were extremely useful when human jaw structures were wider, and actually had enough room to accommodate all 32 teeth. Scientists think they were used to help grind up meat that was much tougher than what’s typically consumed today. However, as society developed softer foods and dining utensils, jaw structure narrowed.
Basically, the idea is that wisdom teeth used to have a very good purpose, but humans haven’t quite evolved to the point where they stop growing in, even though they’re no longer needed.
Should I Still Have Them Extracted?
It depends on your case. More often than not, emerging wisdom teeth cause more problems than their worth. Since most people don’t have room for them, they tend to become trapped below the gumline, which can result in infection or painful dental shifting. Some individuals simply never grow wisdom teeth, though, and others are able to keep them and maintain their oral health.
Regardless of why so many humans develop third molars, you should check in with your dentist to confirm whether you have any that need to be extracted. They’ll make sure you get the care you need!
