Our Changing Diets and Jaws
We no longer need wisdom teeth because our diets and jaw structures have changed significantly over time.
- Smaller Jaws: Our ancestors ate tougher, more fibrous foods that required strong chewing muscles and larger jaws. This created space for wisdom teeth to erupt without crowding.
- Softer Diets: Modern diets consist of processed and cooked foods that are easier to chew. This has led to smaller jaws and less space for wisdom teeth.
- Evolution: Our jaws have evolved to accommodate these changes. We no longer need the extra chewing power that wisdom teeth provided, and they can actually cause problems in our smaller jaws.
The Problems with Wisdom Teeth
Wisdom teeth, also known as third molars, often erupt in a crowded mouth. This can lead to:
- Impacted Wisdom Teeth: When wisdom teeth get stuck and cannot erupt properly, they are called impacted. This can cause pain, infection, and damage to nearby teeth.
- Crowding: Impacted wisdom teeth can push other teeth out of alignment, causing crookedness and bite problems.
- Cysts: In some cases, impacted wisdom teeth can form cysts, which are fluid-filled sacs that can damage bone and teeth.
Removing Wisdom Teeth
Because of the problems they can cause, many people choose to have their wisdom teeth removed. This is a common surgical procedure that is usually done under local anesthesia.
It's important to note that not everyone needs to have their wisdom teeth removed. If they erupt properly and do not cause any problems, they can remain in place. However, it's essential to see a dentist regularly to monitor wisdom teeth and ensure they don't become problematic.
