Wisdom Teeth: What You Need to Know

What Are Wisdom Teeth?

Wisdom teeth, also known as third molars, are the last adult teeth to come in. Most people have four wisdom teeth, two on the top and two on the bottom.

When Do Wisdom Teeth Come In?

Wisdom teeth typically start to erupt between the ages of 17 and 25. However, some people may not get their wisdom teeth until their 30s or 40s, or they may never get them at all.

Why Do We Have Wisdom Teeth?

The exact reason why humans have wisdom teeth is not known, but there are a few theories. One theory is that wisdom teeth helped our ancestors chew tough foods, such as nuts and seeds. Another theory is that wisdom teeth were useful for grinding down food when our diets were more plant-based.

Problems with Wisdom Teeth

Wisdom teeth can sometimes cause problems, such as:

• Impaction: Wisdom teeth that are impacted, or stuck in the jaw, can cause pain, swelling, and infection.
• Crowding: Wisdom teeth can crowd other teeth, causing them to become misaligned.
• Caries: Wisdom teeth are often difficult to clean, which can lead to cavities.

Treatment for Wisdom Teeth

If wisdom teeth are causing problems, your dentist may recommend having them removed. Wisdom teeth are typically removed in a simple surgical procedure.
