Why do we have wisdom teeth?
Scientists have discovered that our early ancestors would have used their wisdom teeth much more than we need to today. They would have replaced teeth lost through trauma and decay, and the prehistoric diet and lifestyle would have required a broader jaw for chewing rougher, coarser food.
Today, of course, wisdom teeth aren’t nearly as welcome. Thanks to softer diets, improved dental care and shrinking jaws, squeezing in these extra teeth can cause an array of problems and often mild-to-severe discomfort.
When your wisdom teeth eventually break through, they can sometimes get stuck. This is known as the tooth being impacted, and a fully impacted wisdom tooth will remain completely hidden beneath the gums. Partially impacted wisdom teeth will peek through the gums, meaning they can be glimpsed at the back of the mouth.
