It’s one of the most common dental procedures we perform, but many patients still wonder: why do wisdom teeth so often need to be taken out? At Cheltenham Dental, we think it’s important to explain the ‘why’ behind any treatment, especially one that might sound a little intimidating.
If you or your teen are facing the possibility of wisdom tooth removal, here’s what you need to know.
What are wisdom teeth, exactly?
Wisdom teeth are the last set of molars to come through, usually appearing between the ages of 17 and 25. In the past, our ancestors required these extra teeth to help them chew rough, unprocessed food. But over time, as our diets and jaw sizes changed, many people simply don’t have enough space in their mouths to fit them properly.
So why do they need to come out?
Not everyone needs their wisdom teeth removed. If they come through straight, have room to grow, and don’t cause problems, we can often leave them alone. But in many cases, they cause issues like:
Impaction: The teeth get stuck or only partially emerge through the gums. This can lead to pain, infection, and swelling.
Crowding: There’s not enough room in the jaw, so other teeth can shift or become misaligned.
Decay or gum issues: Wisdom teeth are tucked right at the back, which makes them harder to clean. That increases the risk of tooth decay and gum disease.
Cysts or infection: In rare cases, impacted wisdom teeth can form cysts or lead to chronic infections.
Our goal is always to catch these issues early. With regular check-ups and X-rays, we can see what’s happening beneath the surface and recommend the right time to act.
Is it better to take them out early?
In many cases, yes. Removing wisdom teeth earlier — before the roots fully develop and while the bone is still soft — often means a smoother recovery. That’s why we frequently assess wisdom teeth in the late teens or early twenties. But even if you’re older, removal is still safe and manageable with the right care.
What’s the recovery like?
Most people recover well within a few days. You’ll likely experience some swelling and discomfort, but we’ll give you clear instructions and support to help things go smoothly. Many of our patients tell us it wasn’t nearly as bad as they expected.
