Wisdom Teeth: Why Do We Have Them and When Should They Go?

Wisdom teeth are the third molars that typically emerge during late adolescence or early adulthood. Unfortunately, they often lead to oral health issues, prompting the removal of approximately 10 million wisdom teeth each year in the U.S.

Discover why these teeth can be problematic and how Valley Dental Care can help manage them effectively.

What Are Wisdom Teeth?

Wisdom teeth usually appear between ages 18 and 24. Most adults have four wisdom teeth—two in the upper jaw and two in the lower. However, it’s common to have fewer or none at all. Wisdom teeth may also become impacted, meaning they don’t fully erupt through the gums.

Why Do We Have Wisdom Teeth?

Wisdom teeth are remnants from our ancestors, who needed extra molars to grind tougher foods. Modern human jaws are smaller, often leaving insufficient space for wisdom teeth, resulting in various dental issues.

Common Issues Caused by Wisdom Teeth

• Impaction: A tooth that can’t fully emerge, causing pain, infection, or damage to surrounding teeth.
• Tooth decay: Partially erupted teeth can trap food and bacteria, increasing decay risk.
• Pericoronitis: An infection around partially erupted wisdom teeth caused by trapped food and plaque.
• Misalignment: Pressure from erupting wisdom teeth may shift adjacent teeth, impacting orthodontic treatments.
• Cysts and tumors: Fluid-filled cysts may form around impacted teeth, potentially causing bone damage or developing into benign tumors. These often require surgical removal.

When and Why to Remove Wisdom Teeth

If wisdom teeth cause pain, swelling, infection, or other complications, your dentist may recommend removal. Symptoms indicating a problem include facial swelling, persistent pain, sensitivity, or bad breath. Removal may also be proactive, preventing future dental issues even before symptoms arise, according to dental guidelines.
