If youve ever had your wisdom teeth removed or are facing the possibility you might have wondered, Why do we even have wisdom teeth? Are they necessary, or just a painful part of being human? At McLevin Dental Clinic in Scarborough, patients often ask us if wisdom teeth are simply evolutionary leftovers. The answer is yes for most people, they are. Lets dive into the fascinating history of wisdom teeth and their role (or lack thereof) in modern life.
Why Do Humans Have Wisdom Teeth?
Wisdom teeth, also known as third molars, typically appear between the ages of 17 and 25. They were incredibly useful to our ancestors, whose diets consisted of rough, fibrous foods like roots, nuts, raw meat, and leaves. These foods required a lot of chewing, and extra molars at the back of the mouth were essential for grinding.
Back then, dental hygiene was non-existent. Tooth loss was common by early adulthood due to decay, breakage, or wear, so the arrival of wisdom teeth served as a natural backup set.
Evolution Has Outpaced Our Jaws
Over time, human diets changed dramatically. Cooking and food preparation softened what we eat, making intense chewing less necessary. Additionally, the human jaw gradually became smaller through evolution. As a result, there often isnt enough space in modern jaws for wisdom teeth to erupt properly.
This mismatch between our jaw size and the number of teeth is why so many people experience:
Impacted wisdom teeth (trapped under the gum or bone)
Crowding of other teeth
Infections and swelling
Pain and jaw stiffness
Are Wisdom Teeth Useless Today?
For the majority of people, wisdom teeth serve no functional purpose today. In fact, in many cases, they cause more harm than good. Impacted or partially erupted wisdom teeth create pockets where bacteria thrive, leading to infections, gum disease, and even damage to neighboring teeth.
However, there is a small percentage of people who naturally never develop wisdom teeth at all a sign of ongoing human evolution. Others may have them erupt fully aligned and healthy but this is increasingly rare.
Common Problems Associated With Wisdom Teeth
Infection (Pericoronitis) Gums around partially erupted teeth can swell and become painful.
Decay Wisdom teeth are hard to clean, making them cavity-prone.
Crowding Erupting wisdom teeth can push other teeth out of alignment.
Cysts or Tumors In rare cases, impacted wisdom teeth can lead to cysts or damage to the jawbone.
Do All Wisdom Teeth Need to Be Removed?
Not always. At McLevin Dental, we assess each patient individually. If your wisdom teeth are:
Fully erupted
Healthy
Positioned correctly
Easy to clean
Then removal may not be necessary. However, if they are impacted, causing pain, leading to infections, or posing a risk to surrounding teeth, extraction is highly recommended.
How Do I Know If My Wisdom Teeth Are a Problem?
Watch for these signs:
Jaw pain or stiffness in the back of the mouth.
Swollen, red, or bleeding gums near the wisdom teeth.
Difficulty opening your mouth fully.
Bad breath or an unpleasant taste near the back molars.
Crowding or shifting of other teeth.
Regular dental check-ups, including X-rays, help us monitor your wisdom teeth before they become a bigger issue.
Whats the Process of Wisdom Teeth Removal?
At McLevin Dental in Scarborough, we make wisdom tooth removal as comfortable as possible. The process typically involves:
A thorough exam and X-rays to assess tooth position.

Wisdom Teeth and the Future of Dentistry
As humans continue to evolve, some researchers believe wisdom teeth may eventually disappear altogether. More people today are being born without them a clear sign that our bodies no longer find them necessary.
