Wisdom Teeth and Braces

One of the big rites of passage for young adults is wisdom teeth removal.

Of course, there are people who can actually fit those third molars in their jaws comfortably and there are a startling number who don’t even grow them in the first place, but for people who do need their wisdom teeth removed, it’s fun to post pictures of their swollen cheeks and videos of anesthesia antics while enjoying lots of ice cream and smoothies. So what’s the deal with these teeth so many people need removed?

Why Do We Have Teeth That Don’t Fit?

What’s the point of growing an extra set of molars if they don’t even fit in our mouths? We used to think it was all about genes leftover from prehistoric days, but more recently, the leading theory is that it’s actually about the foods we eat compared to what our ancient ancestors ate. Bone can atrophy or grow depending on what we put it through (kind of like muscle), and we simply aren’t giving our jaw bones the same resistance our hunter-gatherer ancestors did.

Prehistoric people’s jaws got an intense workout from grinding up the fibrous plants and raw meat in their diet, which stimulated enough bone growth to make room for the third molars. Today, we eat softer foods that are cooked and processed, so it’s less common for someone’s jaw to grow big enough to fit the wisdom teeth. (We don’t recommend attempting to test this theory, though.)

Why Are Wisdom Teeth Often Extracted?

Despite the growing percentage of people who never get wisdom teeth or don’t get the full set of four, most still get them between their late teens and early twenties, and that can be a problem when there isn’t room. These wisdom teeth tend to end up impacted, or trapped under the gums. They can form cysts or damage the bone tissue or roots of neighboring teeth. This is why extraction is recommended so often.

How Do Wisdom Teeth Interact With Orthodontic Treatment?

Modern evidence shows that wisdom teeth don’t contribute greatly to dental crowding, so they don’t need to be removed for the sake of the straightness of the rest of the teeth. If they do need to be removed for other reasons, that can happen during orthodontic treatment. It’s also a myth that a post-braces smile can be made crooked by wisdom teeth. Our teeth naturally drift as we get older and wear them out more, but not due to wisdom teeth. (So make sure to keep wearing your retainers!)

Let’s Take Care of That Smile!

Everyone’s situation with wisdom teeth is different. Some people need them removed due to impaction, some don’t grow all or any of them, and some get to enjoy the added chewing power of an extra set of molars. We can help you figure out which category you fit into and answer any questions you may have about wisdom teeth and orthodontic treatment.

We love seeing our patients’ smiles!
