What are Wisdom Teeth and Why do we Have Them?

Wisdom teeth commonly need to be extracted, so this leaves many of us wondering why do we have them? Long story short, wisdom teeth were once needed by our ancestors. However, as we have evolved as human beings they are no longer needed. If not removed, wisdom teeth can lead to many complications.

What are Wisdom Teeth?

Also known as third molars, wisdom teeth are the four teeth in the back of the mouth. These are normally the last teeth to erupt and commonly come in between the ages of 17-21.

Wisdom Teeth Problems

As we have evolved as a species our jaw anatomy has changed. We now have smaller upper and lower jaws, which means problems for wisdom teeth. In many cases, there simply is not enough room for these molars.

Problems include:
  • Difficulty properly cleaning erupted third molars due to the positioning in the mouth – problems flossing and brushing leading to decay.
  • Food may become trapped due to the positioning of the teeth and lead to cavity-causing bacteria to grow.
  • Partial eruption can give bacteria a place to enter the gums and create a place for infection to occur. This may also lead to pain, swelling, and stiffness in your jaw.
  • Crowd the neighboring teeth – leading to shifting or movement of other teeth.
  • Impacted, meaning they have not or cannot erupt. The teeth are trapped under the gumline which presents a number of problems.
