In recent years, some dentists have re-evaluated the automatic extraction of wisdom teeth. While the practice of routinely remove wisdom teeth has been common, there are specific situations where keeping your wisdom teeth might be a viable option. However, there are cases where removing them is the best choice.

What Are Wisdom Teeth?

Wisdom teeth, also known as third molars, begin to develop around age seven. By puberty, they become visible on X-rays and typically start to erupt between the ages of 17 and 21. These teeth earned their nickname “wisdom teeth” because they emerge later in life, when individuals are considered more mature and wise.

Why do we have wisdom teeth?

Historically, our ancestors needed wisdom teeth for their tougher, uncooked diets that required more chewing power. Wisdom teeth would have been useful in an age when life expectancy was around 30 years. With the advent of agriculture and softer diets, our jaws have evolved to be smaller, leaving less room for these extra molars.

To extract or not to extract?

Many dentists now choose to monitor wisdom teeth rather than automatically removing them. During regular checkups, your dentist will assess the development and position of your wisdom teeth through X-rays. If issues arise, extraction may be necessary.

Here are some reasons why wisdom teeth might need to be removed:

1. Impacted Wisdom Teeth

An impacted wisdom tooth is blocked from fully emerging from the gum, potentially lying sideways or too close to adjacent teeth. This can damage neighboring teeth and roots, potentially leading to bone loss.

2. Tooth Decay

Wisdom teeth are located at the back of the mouth, making them difficult to clean thoroughly, especially if they are only partially erupted. Trapped food and bacteria can lead to cavities and decay.

3. Infection

Partially erupted wisdom teeth can trap bacteria and create infections in the surrounding gum tissue. This can lead to pain, swelling, and more serious conditions like periodontal disease and bone loss if untreated.

The Extraction Procedure

We usually remove wisdom teeth under local anesthesia with mild sedation or general anesthesia, depending on the complexity of the case. The procedure is generally straightforward and quick, but you’ll need a ride to and from the office.

Post-op care is crucial for recovery. We may prescribe an antibiotic or pain reliever and recommend a softer diet for a few days. Avoid citrus, spicy foods, and alcohol, which can hinder healing. Additionally, refrain from drinking through straws, smoking, or rinsing vigorously, as these actions can cause a condition called dry socket—a painful complication that occurs in about 25% of cases.

What If You Don’t Have Wisdom Teeth?

It’s possible to have only one or two wisdom teeth, or even none at all. As we continue to evolve, variations in wisdom teeth development are becoming more common.
