Does Everyone Have Wisdom Teeth?


Teeth typically erupt in stages, starting from incisors and canines to premolars, and molars. Children will develop an initial set of teeth, lose it, and replace it with another set. Wisdom teeth are the last group of teeth to appear, and they develop at the back of the mouth.

Most young adults receive their wisdom teeth between 17-21. The teeth are named wisdom because they appear when young people join college and learn to be independent. Many people will get four wisdom teeth, but it is normal to have less than four or none at all. By the time the wisdom teeth emerge, the conditions are already very crowded.

Why You May Not Have Wisdom Teeth

Although wisdom teeth were once essential for anearly human dietof nuts, roots, meat, and leaves, these third set of molars are no longer necessary. Today, our diet consists of softer food that’s easy to crush. So why do we have them if we don’t need them?

Studiesshow that wisdom teeth are a leftover relic of human evolution. The development of cooking equipment means that people can now prepare softer food, making wisdom teeth redundant. Scientists also attribute the variation of the number of wisdom teeth to lineage and genetics. For example, Asian Americans and African Americans are more likely to have less than four wisdom teeth than individuals of European descent. Your dentist will analyze an X-ray to determine if you have wisdom teeth.

What if My Wisdom Teeth Have Not Erupted?

Sometimes, wisdom teeth get trapped in the jaw or under the gums and fail to erupt fully. If a wisdom tooth does not erupt correctly, it may become impacted and result in infection, nerve damage, or pain.

The primary reason for non-erupted wisdom teeth is insufficient room in the oral cavity. An adjacent second molar can also discourage a wisdom tooth from emerging. If your wisdom teeth have not emerged, your dentists will use X-rays and clinical examinations to forecast their eruption and determine if removal is necessary.

When to See Your Dentist

Every person is different, and you will not know precisely when your wisdom teeth will emerge. The most common indicator of impacted wisdom teeth is pain at the back of your mouth, although some people do not feel pain. While you can expect some gum or jaw pain, do not ignore intense pain that could indicate an abscessed tooth.

Wisdom teeth removal reduces the chances of:

  • Infection
  • Cavities
  • Loss of bone support
  • Nerve pain
  • Shifting teeth
